1. Field of the Invention: The present invention relates to a slide fastener chain for slide fasteners, and more particularly to a slide fastener chain having a multicolor ornamental portion along each of confronting inner longitudinal edges of a pair of its fastener tapes, the ornamental portion being exposed to outside when the slide fastener is used on an article. 2. Description of the Related Art: Conventional ornamental slide fasteners each bearing a pattern of design over the entire surface of a slide fastener chain including a pair of fastener elements are disclosed by, for example, Japanese Utility Model Laid-Open Publications Nos. Sho52-47908 and Hei6-9510. With such a conventional slide fastener chain, since the fastener tapes is usually sewn to rear surfaces of edge portions of an opening of an article to which the slide fastener chain is attached, the pattern of design born over the entire front surface of each fastener tape was concealed by the cloth of the article and could not be seen.

Each row of coiled fastener elements 3 is sewn by two parallel double-loop stitches. Each row of the stitches is formed with a single needle and two threads, i.e. a single multicolor thread 6 as a looper thread and a sewing threads 7 as a needle thread. The two rows of rainbow-colored neat ornamental portions 8 formed of the multicolor threads 6 appear contrastively and clearly on a front surface of each row of the transparent or light-colored coiled fastener element 3; this arrangement is particularly suitable with large-sized fastener elements. These two rows of ornamental portions 8 may be either identical or different in colors; if they are identical with each other, a wide neat ornamental portion 8 would appear on the front surface of each coiled fastener element 3. The fastener element 3 of a synthetic fiber monofilament should by no means be limited to a coiled type and may alternatively be a zigzag type. FIGS. 7 and 8 show a slide fastener chain 1 according to a fifth embodiment. In this slide fastener chain 1, a pair of rows of zigzag-shaped fastener elements 3 are respectively sewn astride of and to a pair of fastener tapes 4, 4 along their confronting inner longitudinal edges by double-loop stitches using a single needle and two threads, i.e. a single multicolor thread 6 as a looper thread and a sewing thread 7 as a needle thread. As a result, a rainbow-colored neat ornamental portion 8 appears on a front surface of each row of the zigzag-shaped fastener elements 3. FIG, 9 shows a slide fastener stringer 2 according to a sixth embodiment. In this slide fastener stringer 2, a row of zigzag-shaped fastener elements 3 is mounted astride of an inner longitudinal edge of a fastener tape 4, and then a white or light-colored narrow blade 9 is placed over a front surface of the row of fastener elements 3, whereupon the row of fastener elements 3 is sewn to the fastener tape 4 by two parallel rows of double-loop stitches with a single needle and two threads in such a manner that multicolor threads 6 as looper threads constitute a pair of rainbow-colored neat ornamental portions 8 appearing contrastively on the white or light-colored narrow blade 9. These two ornamental portions 8 may be identical or different in colors. FIG. 10 shows a slide fastener stringer 2 according to a seventh embodiment. In this embodiment, like the sixth embodiment of FIG- 9, a row of zigzag-shaped fastener elements 3 is mounted astride of an inner longitudinal edge of a fastener tape 4, and then a narrow blade 9 is placed on a front surface of the row fastener elements 3, whereupon the row of fastener elements 3 is sewn to the fastener tape 4 by two parallel rows of double-loop stitches with a single needle and two threads. using a multicolor thread 6 as a looper thread. The multicolor threads 6 constitute an ornamental portion 8 on the front surface of the blade 9, and the blade 9 also is colored in various colors to constitute a wide ornamental portion 8. The arrangement of colors of each of the multicolor threads 6 and the blade 9 may be selected as desired. The sewing means should by no means be liitated to double-loop stitches with a single needle and two threads. FIG. 11 shows a slide fastener chain 1 according to an eighth embodiment. In this embodiment, a pair of rows of transparent or light-colored zigzag-shaped fastener elements 3, through which two core cords 5 are respectively inserted, is mounted on a front surface of a pair of fastener tapes 4 along their inner longitudinal edges, whereupon each row of zigzag-shaped fastener elements 3 is sewn to the respective fastener tape 4 by double-loop stitches with a single needle and two threads, a multicolor thread 6 as a looper thread and a sewing thread 7 as a needle thread. As a result, the multicolor threads 6 constitute a rainbow-colored neat ornamental portion 8 appearing contrastively on the front surface of each row of zigzag-shaped fastener elements 3. The row of fastener elements 3 should by no means be limited to a synthetic fiber monofilament and may be molded of thermoplastic resin, such as polyamide, polyester or polypropylene, like a ninth embodiment as shown in FIGS. 12 and 13. As shown in FIGS. 12 cind 13, a succession of fastener elements 3 of thermoplastic resin is molded on a synthetic fiber connecting thread 10 at a predetermined pitch by extrusion molding. Each of the fastener elements 3 is folded about their coupling heads with their opposite legs 11 astride of an inner longitudinal edge of a fastener tape 4. The successive fastener elements 3 are sewn at a succession of recesses 12 on the legs 11 thereof to the fastener tape 4 by double-loop stitches with a single needle and two threads, i.e. a multicolor thread 6 as a looper thread and a sewing thread 7 as a needle thread. The succession of recesses 12 on the front legs 11 are filled with the multicolor thread 6, while a succession of recesses 12 on the rear legs 11 receive the sewing thread 7. Thus the multicolor thread 6 constitutes a rainbow-colored neat ornamental portion 8 appearing on the front surfaces of the fastener elements 3. Preferably the fastener elements 3 are while or light-colored so that the ornamental portion 8 thereon can be set off. FIGS. 14 and 15 show a slide fastener chain 1 according to a tenth embodiment. In this embodiment, a succession of fastener elements 3 of thermoplastic resin are molded directly on a front surface of a fastener tape 4 along its inner longitudinal edge by injection molding, whereupon the successive fastener elements 3 are sewn at a succession of recesses 12 on the legs 11 thereof to the fastener tapes 4, 4 by double- loop stitches with a single.needle and two threads, i.e. a multicolor thread 6 as a looper thread and a sewing thread 7 as a needle thread. The succession of recesses on legs 11 of the fastener elements 3 are filled with the loops of the multicolor thread 6. As a result, a rainbow-colored neat ornamental portion 8 appears on the front surface of the fastener elements 3. In the foregoing embodiments, the fastener elements 3 are of any of various types. Though the multicolor thread 6 constitutes an ornamental portion 8 on a front surface of the fastener elements 3, it should by no means be limited to as a looper thread and may alternatively be used as a needle thread. As another alternative, the core cord 5 inserted through the fastener elements 3 may be multicolored by suitable means as shown in FIG. 16, in order to make the slide fastener chain 1 much more colorful. Further, the fastener elements 3 may be colored with a fluorescent dye or may contain a luminous pigment, so that an article to which the slide fastener is attached can be used in night and day. In either case, elegant colors of the multicolor thread 6 should appear on the front surface of each row of the fastener elements 3 as the fastener elements 3 set off the ornamental portion 8 of the multicolor thread 6. The arrangement of colors of the ornamental portion 8 on one slide fastener stringer 2 may be asymmetrical with that of the other slide fastener stringer 2. Or, the opposite stringers 2, 2 may be symmetrical in form and color. In use, the fastener tapes 4 of the slide fastener chain 1 are sewn to the rear surfaces of marginal portions of an opening at the front part of a garment or wear in such a manner that at least the fastener elements 3 and, the ornamental portions 8 are exposed to outside from the opening. The slide fastener chain of the present invention has advantageous results as follows: According to the first aspect of the invention, partly since the fastener elements 3 are sewn to the fastener tapes 4, 4 along their confronting inner longitudinal edges by the multicolor threads 6, and partly since the multicolor threads 6 constitute ornamental portions 8, it is possible to manufacture a slide fastener chain 1 having a multicolored elegant ornamental portion 8 by a simple process. These multicolored elegant ornamental portions 8 on the front surface of the slide fastener chain 1 can appear when the slide fastener is used on an article such as a garment. According to the second aspect of the invention, partly since the multicolor sewing threads 6 are colored with a plurality of kinds of different color dyes or pigments, partly since the different colors of the multicolor sewing threads 6 are regularly eirranged. each of successive portions of the different colors has a predetermined length, it is possible to produce the multicolored threads 6 and neat ornamental portions 8 in a simple manner. According to the third aspect of the invention, partly since the multicolor sewing threads 6 are colored with different color dyes or pigments, partly since the different colors of the multicolor sewing threads 6 are arranged at random, and partly since each of successive portions of the different colors has an arbitrary length, it is possible to produce the multicolor threads 6 quickly and simply. According to the fourth aspect of the invention, since each of said multicolor sewing threads 6 is composed of a plurality of monofilaments individually colored and twisted into a unit, it is possible to produce the multicolor threads 6 having various colors arranged at random, thus, neat ornamental portions 8 Eire realized in a simple manner. According to the fifth aspect of the invention, since the multicolor sewing threads 6 are double-loop-stitch looper threads arranged in a single row, it is possible to produce a multicolored neat ornamental portion 8 with maximum ease by a simple sewing means. According to the sixth aspect of the invention, since the multicolor sewing threads 6 are double-loop-stitch looper threads eirranged in two rows, it is possible to produce a multicolored neat wide ornamental portion 8 with ease by a simple sewing means. According to the seventh aspect of the invention, since the fastener elements 3 are thermoplastic synthetic fiber monofilaments that are transparent or light-colored, it is possible to set the multicolored ornamental portion 8 off the filamentary fastener elements 3 so that the ornamental portion 8 can appear clearly and neatly. According to the eighth aspect of the invention, since the fastener elements 3 are molded of thermoplastic resin by extrusion or injection molding, it is possible to set the multicolored ornamental portion 8 off the extrusion- or injection-molded fastener elements 3 so that the ornamental portion 8 can appear clearly and neatly. According to the ninth aspect of the invention, since a pair of blades 9, 9 each of which covers an upper surface of each row of the fastener elements 3 and are sewn to each of the fastener tapes 4, 4 by the multicolor sewing threads 6, It is possible to set the multicolored ornamental portions 8 off the blades 9, 9 contrastively and to produce it in a simple manner. According to the tenth aspect of the invention, since each of the blades 9, 9 on the fastener elements 3 are colored in a plurality of colors, it is possible to produce a wide ornamental portion 8 on the front surface of the fastener element 3 simply. According to the eleventh aspect of the invention, since the ornamental portion 8 constituted by the multicolor sewing threads 6 on both of the fastener stringers 2, 2 are identical in shape and arrangement of colors with respect to each other, it is possible to match the arrangement of colors of the ornamental portion 8 on one slide fastener stringer 2 with those of the ornamental portion 8 on the other side fastener stringer 2, thus realizing well-balanced neat ornamental portions 8. According to the twelfth aspect of the invention, since each of the fastener tapes 4, 4 has near the fastener elements 3 an ornamental portion of multicolor threads 6' to constitute another ornamental portion 8', the ornamental portions 8' on the fastener tapes 4, 4 appear in harmony on the fastener elements 3, thus making the side fastener chain 1 more colorful.
