2. Description of the Related Art Conventionally, in order to form three-dimensional characters, marks, patterns, etc. on the surface of another product, Japanese Patent Application Laid-Open No. 59-14038
4, or by a method as disclosed in JP-A-64-26184. FIG. 4 shows a typical conventional example. A metal layer of a required pattern is formed and held on the lower surface of the adhesive tape 1 using a photoresist electroforming method or the like, and further, an adhesive 6 is applied to the lower surface of the metal layer, and then an adhesive layer protective liner 7 is cut to a required size. 2. Description of the Related Art There has been widely used a method of separately attaching a part to be directly attached to a part of a product to be decorated which requires decoration. However, according to this method, the decorative pattern components such as characters, marks, and patterns, which are once formed of the metal layer, are simply pasted once to the surface of the product to be decorated. Stay in range. In addition, such a conventional method cannot solve one of the causes of the appearance defect by causing the adhesive 6 to protrude at the boundary portion between the pattern and the base portion to be adhered or to cause a line irregularity as the fineness of the decorative pattern increases. Was. Furthermore, minimizing the bonding area to solve the above-mentioned drawbacks reduces the adhesive strength of the decorative part, and may cause serious drawbacks such as falling off.

[0003]

As seen from the above, according to the prior art, the three-dimensional effect is limited to a single layer of the metal layer pattern. Further, the fineness of the decorative pattern is limited due to the balance between the finished beautifulness of the boundary between the pattern and the base and the adhesive strength to the base.

[0004] It is an object of the present invention to increase the density of the three-dimensional appearance and to expand the possibility by stacking decorative patterns. Another object of the present invention is to improve the fineness of the decorative pattern by improving the beauty of the boundary line of the three-dimensional portion and improving the adhesive strength of the decorative component.

[0005]

Means for solving the above problems are as follows. A temporary fixing adhesive is applied to the back surface of the final decorative pattern layer, and the temporary adhesive is applied to a substrate having an area sufficient to laminate the entire decorative pattern. After fixing by the above, a step of applying a transparent or colored paint on the entire upper surface of the laminated product, then forming an adhesive layer for full-scale fixing on the back surface of the laminated product, attaching an adhesive layer protective liner to the final decorative component And the step of performing. In this configuration, as a method of full-scale fixing of the laminated product, a fixing pin can be formed on the back surface of the laminated product, and the laminated product can be fixed to the decorative object. In this case, the fixing pins are formed at the stage of the substrate before the final decorative pattern is temporarily bonded to the substrate, and, following this process, the final decorative pattern is temporarily contacted, and finally the transparent or colored paint is applied. Completed as a product. Furthermore, it is also possible to add two or more multi-layers to the substrate by layering decorative patterns, and by overlapping or combining such methods, the possibility of overcoming the unavoidable limits of expression in the past can be overcome. give.

[0006]

The delicate decorative pattern layer is firmly adhered and laminated to the substrate by the application of the paint after the temporary adhesion to the substrate by the penetration of the paint liquid. The increase in the fixing strength makes it possible to laminate finer and finer decorative patterns between layers, and to obtain a decorative component having a deep decorative pattern. In addition, after the decorative pattern is once fixed on the substrate and then bonded to the surface of the product to be decorated, the bonding area can be kept large, and the bonding strength of the decorative component can be improved.
