IMIDE COMPOUND AND
OPTICAL RECORDING MEDIUM USING THE SAME
Technical Field
The present invention relates to an optical recording medium, and
more specifically, an optical recording medium capable of writing and reading
by a visible laser, a blue laser beam In addition, the present invention
relates to a novel imide compound
Background Art
As a recordable optical recording medium corresponding to the
specifications of a compact disk (hereinafter simply referred to as a "CD"), a
CD-R (CD-Recordable) has been widely spread The storage capacity of
the CD-R is about 680 MB However, with a drastic increase of the
information volume, demands for higher density and larger storage capacity
in an information recording medium have been increased
As a means for achieving higher density of a recording medium, it is
considered to decrease a beam spot by using a shorter-wavelength laser in
writing and reading and increasing a numerical aperture (N A ) of an object
lens As the short-wavelength laser for use in an optical disk system, red
laser beams of 500 to 700 nm, further 630 to 690 nm, more specifically, 680,
670, 660, 650, and 635 nm have been put to practical use Thus, by virtue
of techniques for reducing the wavelength of a semiconductor laser,
increasing the numerical aperture of an object lens, and compressing data,

an optical recording medium capable of recording a motion picture and large
volumetric information has been successfully produced. Examples of optical
recording media proposed up to the present include a magneto-optical
recording medium, phase change recording medium, chalcogen oxide-based
optical recording medium, and organic dye-based optical recording medium
Of them, the organic dye-based optical recording medium is considered
preferential in view of low cost and easy processing. In consideration of
these circumstances, the one developed as an optical recording medium
capable of recording and regenerating a motion picture with the same quality
level as that of TV and with a higher density than that of CD and as a
recordable optical recording medium capable of regenerating by a
commercially available DVD video player or a DVD-ROM player that have
been widely used and capable of recording by a rea semiconductor laser
having an oscillation wavelength of 630 to 690 nm is a recordable digital
versatile disc (hereinafter, simply referred to as a "DVD-R"). DVD-R is a
write-once optical recording medium having a 3.9 or 4.7 GB storage capacity.
In particular, only recently, a DVD-R medium having a single-side capacity of
4.7 GB has been brought into a market. Such a DVD-R medium also
employs a stacked structure, which is formed of a recording layer containing
a cyanine-based dye, azo-based dye, or the like, and a reflecting layer, is
characterized by a disk structure formed by adhering two substrates of 0.6
mm thick. Regarding such an optical disk having satisfactory recording
characteristics suitable for this capacity, development of a medium applicable
to high-speed recording has been aggressively made at present.
Furthermore, it has been estimated that a further higher density

recording will be desired in future and that the amount of data stored in a
single disk will reach up to 15 to 30 GB To attain such a recording density,
a further shorter-wavelength laser will be inevitably used Accordingly, as a
recording dye suitable for an on-coming organic dye-based optical recording
medium, it is desired to develop a dye having good recording characteristics
within the wavelength range of 300 to 500 nm
In the meantime, regarding a medium attaining high-density recording
more excellent than DVD-R using an organic dye in a recording layer,
Japanese Patent Laid-Open No 10-302310 discloses that a recording
density having a storage capacity of 8 GB or more is attained by using a
laser having an oscillation wavelength of 680 nm or less This publication
suggests that a large storage capacity of 8 GB or more should be attained by
converging laser light of 680 nm or less through an object lens having a high
numerical aperture of 0 7 or more via a light transmission layer of 10 to 177
pm thick.
On the other hand, only in recent years, as a blue laser having an
oscillation wavelength of 390 to 430 nm, a laser of 410 nm using a GaN-
based material and an SHG laser of 425 nm wavelength, which is obtained
by combining a semiconductor laser and an optical wave guide element,
have been developed (for example, January 26 Issue of Nikkei Electronics,
No. 708, p 117, 1998) Thus, development of blue semiconductor laser
applicable dyes suitably used in such a laser is now proceeding.
Furthermore, Nichia Corporation started supply of a GaN-based
semiconductor laser emitting bluish-violet light having an oscillation
wavelength of 400 to 410 nm from the beginning of 1999 Since then,

studies on a medium having a high-density storage capacity of 15 GB or
more per side (hereinafter referred to as an "HD-DVD-R medium") and
capable of recording a motion picture having the same image-quality level as
that of a high definition television (HDTV) for about 2 hours have been
started Such an HD-DVD-R medium is capable of recording motion
pictures for about 6 hours with the same image-quality level as those
currently on air and therefore attracted attention also as a new recording
medium in place of a home VTR Already now, technical outline of a
proposal for a medium using an inorganic recording film of a phase change
system has been introduced in September 6 Issue of Nikkei Electronics, No
751, p 117(1999)

Further, the optical recording media are proposed including an optical
recording medium described in Japanese Patent Laid-Open No 11-53758,
which is formed of two layers, one is a recording layer primarily containing a
porphyrin-based dye or cyanine-based dye as an organic dye for forming the
recording layer and the other is a metal reflecting layer primarily containing

silver, an optical recording medium described in Japanese Patent Laid-Open
No 11 -203729 which attains writing in 2 wavelength regions by devising the
constitution of a medium, that is, using a medium having a blue laser
responsive dye layer containing a cyanine-based dye responsible to a blue
laser and a red laser responsive dye layer, an optical recording medium
using an indigold-based dye compound described in Japanese Patent Laid-
Open No 11 -78239 which attaining writing in two wavelength regions by
mixing two types of dyes, that is, a dye for a blue laser and a dye for a red
laser, an optical recording medium using a cyanoethene-based dye
described in Japanese Patent Laid-Open No 11-105423, and an optical
recording medium using a squarylium-based dye compound described in
Japanese Patent Laid-Open No 11-110815
On the other hand, as examples for using an organic dye film for
writing within the blue region of 400 to 500 nm, Japanese Patent Laid-Open
Nos. 7-304256 and 7-304257 have suggested to mix a molecular compound
coordinated to the central metal of a porphyrin-based compound and a
polymer or a polymer having a molecular structure having a central metal
coordinated as a side chain, thereby shifting the Soret zone of the porphyrin-
based compound toward a long wavelength range so as to correspond to an
Ar laser of 488 nm, and simultaneously to reduce manufacturing cost by
achieving film formation by spin coating Furthermore, Japanese Patent
L aid-Open Nos 4-78576 and 4-89279 disclose polyene-based color
compounds, which are, however, poor in light stability according to the
studies by the present inventors, and required some modifications, for
example, blending of a quencher or the like, to put them to practical use

As the recent circumstances, since the prospect of putting a bluish-
violet semiconductor laser of 400 to 410 nm wavelength to practical use is
given, development of a high-capacity recordable optical recording medium
using the laser has been aggressively made and particularly development of
dyes having excellent light stability and high-speed recording characteristics
has been desired
However, the optical recording media mentioned above are actually
insufficient to be subjected to the laser light having a wavelength of 400 to
410 nm More specifically, the media using the organic dyes mentioned
above have a problem in that when recorded signal data is read out, the
read-out of a signal is not satisfactory performed, since the ratio of carrier to
noise (C/N) is not always proper Therefore, development of an optical
recording medium capable of overcoming this problem and writing and
reading high-density data by a laser beam of 400 to 410 nm wavelength has
been urgent need
As a result of studies conducted by the present inventors on recording
materials suitable for an optical recording medium, the following two findings
were obtained
(1) Since a large capacity optical recording medium uses a laser beam
of 300 to 500 nm in writing and reading data, it is important to control the
absorption coefficient, refractive index, and reflectivity of the recording
medium in the vicinity of the laser wavelength.
(2) As mentioned above, although large-capacity optical recording
media using the laser have been aggressively developed and particularly the
development of a dye having excellent light stability and good high-speed

recording characteristics has been desired, the dye compounds mentioned
above have not yet satisfied recording characteristics as a recording material
capable of reading and writing data with a laser beam of the wavelength
range and thus still need to be improved at present Furthermore, as a
favorable characteristic of a dye for use in a medium manufactured by a
coating method, such as spin coating, which is a simple method for forming a
recording film, the high solubility of the dye to a coating solvent must be
considered
Also, in general, to increase the storage capacity, higher-density
recording must be performed To attain this, it is necessary to increase the
numerical aperture of an object lens in order to converge an optical beam for
use in recording and generate a shorter-wavelength laser by an optical
system. However, when an optical beam is converged, the minimum beam
diameter is determined by its diffraction-limit
In the meantime, since writing is made when the intensity of beam
exceeds a certain threshold, the record pit obtained is smaller than the beam
spot converged, as shown in Figure 1 (a) The periphery of the record pit
corresponds to the skirts of the intensity peak. Under the present
circumstances where a further shorter wavelength laser is developed, a
photochemical reaction in the recording layer is facilitated even in the
periphery of the record pit In particular, in the wavelength range of the
aforementioned bluish-violet laser, a photochemical reaction of an organic
compound is likely to occur, producing a problem a pit edge is degraded
during writing time, decreasing signal characteristics To explain more
specifically, recoding data which must be essentially written in response to a

rectangular wave [indicated by a solid line in Figure 1(b)], as shown in Figure
1(b), results in a broader tailed wave form (indicated by a broken line in
Figure 1 (b) due to the deterioration of the pit edge Furthermore, when
regeneration is performed by the same bluish-violet laser wavelength as in
recording, a photo reaction is facilitated even by weak light irradiation such
as regeneration light As a result, deterioration proceeds every time
regeneration is performed. Against such a problem, Japanese Patent Laid-
Open Nos 7-304256 and 7-304257 take measures by varying the
wavelength of recording light from that of regeneration light, virtually, using a
longer wavelength light as regeneration light than recording light As a
result, the requirement for high-density recording has not yet sufficiently
satisfied up to present Furthermore, using recording light and regeneration
light different in wavelength means that a recording device and a
regeneration device must be separately prepared or means that two optical
systems and control systems must be provided in a single apparatus, with
the result that such an optical recording medium is limited in use and entails
enlargement of the apparatus, increase of cost, and losing general versatility
Furthermore, in a conventional optical recording medium such as CD-R,
on/off of writing can be determined based on whether or not reaching thermal
threshold on physical characteristics such as melting point, sublimation point,
phase transition point or thermo-decomposition point of an organic dye film.
However, such a contrast is made indistinctive by optical deterioration due to
excitation of a bluish-violet laser. In particular, in a high-density recording
system in which recording pits must be formed smaller than that of an optical
beam, there is a possibility that the quality of a recording signal may

significantly decrease
Now, as a case where an organic dye film is used in recording in the
visible light range of 400 to 700 nm, Published Japanese translations of PCT
international publication No 2002-501497 describes a writable and erasable
optical recording medium using a perylene-based compound. Further,
Japanese Patent Laid-Open No 10-6645 describes a laser beam of 620 to
690 nm wavelength used on a medium using a perylene compound analogue
in the recording layer However, it was found that these compounds are still
insufficient with respect to light stability and signal characteristics when a
bluish-violet laser of 400 to 410 nm wavelength is used for writing
Also, as an optical recording medium using an organic dye, on which
recording can be made by a laser of 400 to 500 nm wavelength, Japanese
Patent Laid-Open No 2000-113504 describes an optical recording medium
using a naphthalene imide compound However, it was found that the
compound was still unsatisfactory in light stability and the recording medium
thus required further improvement.

Best Mode for Carrying Out the Invention
The present invention relates to an optical recording medium
characterized by containing an imide compound of the present invention in a
recording layer thereof, and a novel optical recording medium capable of
writing and reading by a laser beam selected from the wavelength range of
300 to 900 nm, particularly from 390 to 430 nm, and more particularly from
400 to 410 nm and a novel imide compound
The optical recording medium according to the present invention is one
capable of writing and reading data However, herein, as an appropriate
example, an optical recording medium of the present invention having a
recording layer and a reflecting layer on a substrate will be explained. Note
that, in the following explanation, as an optical recording medium, an optical
disk, which has a supporting substrate having guide grooves and a reflecting
film and a recording layer containing an organic dye as a main component
formed on the guide grooves, to which a laser beam of a wavelength of 300
to 500 nm is applied to perform read and write of a signal, will be described
However the optical recording medium of the present invention is not limited
to such a structure and constitution, and may be applied to the media of a
card-form, sheet-form and other forms, and having no reflecting layer, and
applied to writing and reading performed by a shorter wavelength laser which

will be developed in future
An optical recording medium of the present invention has, for example,
either a four layered structure in which a substrate 1, a recording layer 2, a
reflecting layer 3 and a protecting layer 4 are sequentially stacked as shown
in Figure 2 or a bonded structure as shown in Figure 3 More specifically,
the recording layer 2 is formed on the substrate 1 and the reflecting layer 3 is
formed on and in close contact with the recording layer 2 Further on the
resultant structure, the protecting layer 4 is bonded with an adhesion layer 5
interposed between them Note that another layer may be present under or
on the recording layer 2 and another layer may be present on the reflecting
layer 3 Alternatively, as shown in Figure 4, the substrate 1, reflecting layer
3, recording layer 2, and protecting layer 4 are sequentially stacked and read
and write may be performed from the side of the protecting layer As
described in Japanese Patent Laid-Open No 10-326435, a medium may
have a structure in which the thickness of a light transmission layer is defined
based on the numerical aperture (N A ) of the optical system and the
wavelength X of a laser. Furthermore, an optical recording medium of the
present invention may have a structure having two or more recording layers if
necessary as described in Japanese Patent Laid-Open No 11-203729
As an example where the present invention is applied to an optical
disk, a structure as shown in Figure 5 may be mentioned in which a substrate
11, a recoding layer 12, a reflecting layer 13 and a protecting layer 14 are
stacked in this order and further a dummy substrate 15 is bonded on the
protecting layer 14 also serving as an adhesion layer Of course, a structure
having no substrate 15 may be used and other layers may be present

between the substrate 11 and the recording layer 12, between the recording
layer 12 and the reflecting layer 13, between the reflecting layer 13 and the
protecting layer 14, and between the protecting layer 14 and the dummy
substrate 15 In the optical disk of Figure 5, write and read may be
performed from the side of the substrate 11
Furthermore, as another embodiment, the constitution disclosed in
Japanese Patent Laid-Open No 10-302310 may be used For example, as
shown in Figure 6, on the supporting substrate 11' having guide grooves
therein, a reflecting layer 13' and a recording layer 12' containing an organic
dye as a main component are stacked in this order On the recording layer
12', a light transmission layer 15' is formed via a transparent protecting layer
14', which is optionally formed on the recording layer 12' Write and read
are performed from the side of the light transmission layer 15' Note that
guide grooves may be conversely formed on the side of the light transmission
layer 15' and the transparent protecting layer 14', recording layer 12' and
reflecting layer 13' may be stacked on the light transmission layer 15' and
adhered to the supporting substrate 11'
Alternatively, as another embodiment, the structure disclosed in
Japanese Patent Laid-Open No 2002-175645 is known For example, as
shown in Figure 7, on a supporting substrate 21 having guide grooves, a
recording layer 22 containing an organic dye as a main component is formed
in this order On the recording layer 22, a nitride layer 23 and an oxide layer
24 are sequentially formed, thereby forming a dielectric layer 40 Further,
on the dielectric layer 40, a light transmission layer 25 is formed by applying
an adhesive agent between them, if necessary. The write and read of data

is performed from the side of the light transmission layer 25 Note that, the
structure may be conversely formed by forming guide grooves on the side of
the light transmission layer 25, stacking a dielectric layer 40, which is formed
by sequentially stacking the oxide layer 24 and the nitride layer 23, and the
recording layer 22 and adhering to the supporting substrate 21 As
described above, an optical recording medium providing an appropriate initial
reflectivity can be obtained by obtaining an optical enhancement effect due to
multiple interference given by forming a dielectric layer on a data recording
layer without using a reflecting layer A compound of the present invention
can be applied to such a medium
In the present invention, a recording layer is provided on a substrate
The recording layer of the present invention contains at least one type of
imide-based compound according to the present invention, in particular, a
compound represented by a general formula (1), as a recording dye The
recording dye is the one whose thermal decomposition and sublimation can
be induced by laser beam irradiation, to cause a change of a recording layer
or in the texture (formation of pits), thereby forming a portion varied in
reflectivity An optical recording medium of the present invention is capable
of writing and reading data with the wavelength of a recording laser
particularly selected from the wavelength range of 300 to 900 nm More
particularly, when a writing laser wavelength and reading laser wavelength
selected from the range of 390 to 430 nm, and more particularly, from 400 to
410 nm is applied to the optical recording medium, good signal
characteristics can be obtained
An imide compound according to the present invention, since it can

arbitrarily select the absorbing wavelength by selecting a substituent while
maintaining the absorption constant, can provide a satisfactory optical
constant required for the recording layer at the aforementioned laser
wavelength Furthermore, the imide compound is extremely useful organic
dye having a high stability to light and excellent stability of reading light
The present invention will be described in more detail below
In an optical recording medium of the present invention, one or more
types of imide compounds according to the present invention are contained
in the recoding layer As an imide compound according to the present
invention, an imide compound having a metallocene residue, preferably, an
irnide compound having at least one imide group having a metallocene

group consisting of A1 to An is one having at least one substituted or
unsubstituted metallocene residue

heterocyclic aromatic ring It is more preferable to use a substituted or
unsubstituted carbocyclic aromatic ring or substituted or unsubstituted
heterocyclic aromatic ring having 3 to 60 carbon atoms, and further

Although the content of an imide compound according to the present
invention in the recording layer may be arbitrarily set as long as it attains
write and read, usually the content is 30% or more and preferably 60% or
more. Incidentally, it is also preferable that the content be substantially
