BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fastener element for a slide fastener in which the surface of the fastener element is decorated with beautiful decorations and good adhesive properties.

0002

[Prior Art] Conventional fastener elements with beautiful decorations are made by adding a coloring material to the resin itself that makes up the fastener element to give it decorative properties, or by applying a metal vapor deposition method to the surface of the fastener element. Zipper elements have been known that are decorated with a glossy finish unique to metals, and those that are decorated with colored designs printed on the surface of the fastener element using a printing method are known.

0003

[Problems to be Solved by the Invention] Conventional decorative fastener elements other than those decorated by printing methods are limited in the types of decorations; Although it is highly decorative, it has a problem of poor adhesion. SUMMARY OF THE INVENTION An object of the present invention is to solve the conventional problems and provide a fastener element for a slide fastener that is highly decorative and highly adhesive.

0004

[Means for Solving the Problems] In order to achieve the above object, the present invention provides an undercoat layer made of a curable resin on the surface of a fastener element, and a decoration is formed on the undercoat layer by a transfer method. A fastener element for a slide fastener is constructed by providing a layer and then providing an overcoat layer made of a curable resin on the decorative layer. Alternatively, an overcoat layer provided on the decorative layer formed by a transfer method may be configured to hang down from the periphery of the decorative layer and completely cover the decorative layer.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Examples of the present invention will be described below in detail with reference to the drawings. FIG. 1 shows a cross section of the fastener element of the present invention, and is a cross-sectional view of the long fastener chain 1 of FIG. 2 taken along line A-A. The fastener chain 1 to be decorated is made of a woven or knitted colorless or colored fastener tape 2 as shown in FIG.
A pair of fastener tapes 2 in which fastener elements 3 injection-molded from a synthetic resin such as polyacetal, nylon, ABS, or polyester are implanted at regular intervals on the edge of the tape.
are combined in an interlocking state. As shown in FIG. 1, on the surface of each fastener element 3,
The undercoat layer 4 made of a curable resin, the decorative layer 5 which is transferred and adhered by a transfer method in a semi-cured state, and the decorative layer 5 are protected and have good weather resistance, abrasion resistance, and washing resistance. An overcoat layer 6 made of a curable resin is successively formed.

Next, in order to clarify the structure of the fastener element 3 of the present invention, a method of painting the fastener element will be explained. FIG. 3 schematically shows a fastener chain decorating device that applies decoration to each fastener element 3 of the fastener chain 1 during transport. An undercoat layer 4 made of a curable resin is formed on the surface of the fastener element 3 by a dispenser device 10 that can continuously form a precise coating film. The curable resin is preferably a resin that can be formed into a highly resistant film and has good adhesion to the fastener element 3. There are various types of resins, but thermosetting resins, ultraviolet curable resins, electron beam curable resins, etc. are particularly suitable. A coating liquid containing such a curable resin as a main component and made into an ink or a paste using a solvent or the like is filled into the nozzle 11 of the dispenser device 10, and the air pressure applied to the ink and the application time are delicately controlled by the controller 12. The coating is applied by finely adjusting the discharge amount of the needle 13 attached to the tip of the nozzle 11. The undercoat layer 4 is then sent to the next semi-curing device 20 to be semi-cured. Note that the semi-cured state is a state in which the undercoat layer 4 is dry to the touch and not sticky to the touch, and the surface of the undercoat layer 4 remains active.
This improves the adhesion with the next painted layer. Then, a decorative layer 5 is formed on the semi-cured undercoat layer 4 by a roll transfer device 30. The roll transfer device 30 continuously feeds the transfer sheet 31,
The adhesive layer of the transfer sheet 31 is placed on top of the fastener element 3 so that it is in contact with the adhesive layer, and the transfer sheet 31 is heated and pressurized from the base sheet side using a pad roll 32 made of silicone resin to bring them into close contact, and then the base sheet is peeled off. , the part that does not overlap the fastener element 3 is peeled off together with the base sheet, and the fastener element 3 is peeled off together with the base sheet.
The overlapping portion is peeled off at the interface between the base sheet and the release layer of the transfer sheet 31 and remains on the fastener element 3, and a decorated layer 5 is formed on the undercoat layer 4 by the pattern layer of the transfer sheet. . The pattern layer of the transfer sheet 31 may have a design such as a colored pattern or a glossy pattern, or may be a layer in which these are arbitrarily combined. Colored patterns are formed by normal printing methods using colored inks made of normal pigments or dyes, binders, additives, etc. The pattern layer can be a single layer or a multilayer structure with multiple colors. There may be. The glossy pattern is made of a thin film of metal such as aluminum, nickel, chromium, or tin formed by vacuum deposition, sputtering, ion plating, or the like. Next, the zipper chain on which the decorative layer 5 has been formed is sent to a dispenser device 40 similar to the device for forming the undercoat layer 4, where a curable resin similar to that of the undercoat layer 4 is applied, and the overcoat layer 4 is coated with the same curable resin. is formed. In forming this overcoat layer 6, as shown in FIG. 1, it is formed so as to hang down to completely cover the surrounding edges of the decorative layer 5 so as not to peel off from the edges. Finally, the semi-cured undercoat layer 4 and overcoat layer 6 are completely cured in a complete curing device 50 to form a finished zipper chain with pictures as shown in FIGS. 1 and 2 and rolled onto a roll 8. Take and complete. By this complete curing, the undercoat layer 4 is strongly fixed to the decorative layer 5 due to the surface activity remaining in the semi-cured state, and the overcoat layer 6 is
The surface has sufficient weather resistance, abrasion resistance, washing resistance, fastness, etc., that is, the fastener element 3 has sufficient strength against friction with the slider and erosion by water and solvent during washing. Become.

[0007]

[Effects of the Invention] The present invention has the above-mentioned structure, in which a decorative layer is formed on the surface of a fastener element of a long zipper chain by a transfer method using a transfer material, and a decorative layer is formed on the surface of the fastener element of a long zipper chain. Since an overcoat layer is formed on the surface, it is possible to create colored designs by printing, glossy designs by metal vapor deposition, etc.
It is now possible to create paintings that freely combine these designs, resulting in rich decorative properties.The designs are also protected by an overcoat layer, which provides good adhesion, as well as high abrasion resistance and washability. You can obtain beautiful painted fastener elements with durability. Furthermore, if the overcoat layer is formed to hang down from the periphery of the decorative layer, the decorative layer is completely covered, further preventing peeling and improving adhesion.
