PREAMBLE TO THE DESCRIPTION
The following specification particularly describes the nature of this invention and the
manner in which it is to be performed:





TECHNICAL FIELD
The invention relates to wide format printed graphics without release liner.
The invention also relates to a process for the preparation of the wide format printed graphics without release liner.
BACKGROUND OF THE INVENTION:
Wide format printed graphics are used for various purposes mainly as a means of advertisements. They can be perforated or non perforated. The perforated wide format window graphics known as one way vision films are ideal for window advertisements in buildings, offices, shops, retail outlets, service stations or convenience stores, while the non perforated wide format printed graphics are used as posters, billboards, banners, etc.
A wide format printed graphic comprises a perforated / non perforated substrate, which is coated with a pressure sensitive adhesive (PSA) layer on one side and adapted to be printed on the opposite side. The adhesive layer may be black so as to make the film opaque and in case of perforated graphics the adhesive is black to have a clear vision from the unprinted side of the film. The film also comprises a release liner as a protective layer for the adhesive layer. At the time of fixing the printed graphic on a surface, the releaser liner is removed and the adhesive layer side of the printed graphic is press fitted on the surface. But due to the nature of the PSA, the problem of crease formation and misalignment, while applying a self adhesive printed graphic to a surface, especially where permanent PSA is used, is rampant. This ends up in a lot of wastage. In order to facilitate the fixing of the printed graphic on a surface, a soap solution is sprayed onto the surface and / or the adhesive side of the film or alternatively the film is dipped in soap solution. Because of the slimy nature of the soap solution, the printed graphic slides on the surface easily and the fixing of the printed graphic becomes easy. But fixation of the printed graphic with the soap solution is messy and requires skilled workman to slide and
2

reposition the printed graphic on the surface without creases and airgaps between the film and the surface.
Various types of wide format printed such as one way vision films with release liners are well known in the industry as described in the prior arts (Re US 6,258,429, US5,925,437, US5,609,938, US5,773,110, US5,525,177, US4,883,536, US 5,858,155 and US5,679,435, and PCT publication W09965679). The release liners are generally made of glassine or sulphide pulp based papers or are polycoated liners which are not water soluble and cannot be repulped and recycled. Disposal of such liners is problematic and creates environmental pollution. Besides, they are also expensive.
Objects of the Invention:
An object of the invention is to provide a wide format printed graphic, which eliminates the release liner and can be easily fixed on a surface even by unskilled workmen.
Another object of the invention is to provide a wide format printed graphic, which does not create any liner disposable problem.
Another object of the invention is to provide a wide format printed graphic, which is cost-effective.
Another object of the invention is to provide a process for the preparation of a wide format printed graphic having the above advantages, which process is simple, easy and convenient to carry out.

The wide format printed graphics of the invention eliminates the release liner and the necessity of removing it at the time of fixing it on a surface. Resultant liner disposal and environmental problems have also been eliminated. In order to fix the wide format printed graphic of the invention on a surface, water is sprayed or applied on the water soluble protective layer or alternatively the printed graphic is dipped in water so as to dissolve the water soluble protective layer. The printed graphic is straightway fixed on the surface against the adhesive layer and excess water is pressed down. The soap or detergent provides sliminess to the printed graphic and aids to reposition the graphic on the surface without damage to the graphic. The wide format printed graphic of the invention can be thus easily and conveniently fixed on a surface even by an unskilled worker. As the protective layer is water soluble and biodegradable it does not create any disposal and environmental problems. It takes about an hour for the printed graphic to dry up and remain firmly adhered to the surface. The cost of the final product is also reduced as the release liner, which constitutes about 20 to 30% of the whole construction is eliminated and the water soluble protective layer used is very thin and will not add much to the cost of the final product.
Examples:
Example 1:
As per one of the embodiments, a self adhesive material, wherein the substrate was a vinyl film of 150 microns, the adhesive used was an acrylic adhesive and the protective release liner was a silicon coated paper of 150 GSM was perforated on a die cutting machine. The size of the perforations was kept 1.7mm and the percentage of the perforated surface area of the face material was 50%. The perforated release liner was then delaminated and a 20 micron of 'SC 50' grade water soluble film incorporated with 30%» of liquid soap was laminated on the adhesive side of the substrate. The laminate was then slit and cut as desired and the perforated substrate side was then printed by the known inkjet printing method. The printed laminate was then cut to desired size. The water soluble protective layer side of the laminate was then sprayed with water and when the film started becoming tacky, it was applied to the glass window of a building and was repositioned as required.
