Description

[Detailed Description of the Invention] Purpose of the Invention (Industrial Field of Application) This invention relates to a method of manufacturing a thin plate for pasting metal stickers, seals, nameplates, nameplates, etc. (Prior Art) To manufacture stickers and the like from a metal plate, the metal plate is punched into the desired shape, and the metal plate is etched with an etchant such as ferric chloride solution to form the desired pattern. The decorative pieces were finished with metal plating. After plating, apply an adhesive to the back of the decorative piece and releasably attach it to the release paper, then releasably attach a transparent film to the release paper so as to cover the item. 〇 However, in the method described above, in order to manufacture one Stella car, etc., all the decorative pieces are manufactured by punching, etching, and plating, and then the decorative pieces are pasted on release paper and filmed. This made manufacturing very troublesome. Also,
It is also difficult to accurately apply the etchant to the metal plate according to a desired pattern, and it has been almost impossible to obtain an accurate pattern, especially when the design is minute.

Furthermore, when one pattern is not connected to each other and is separated into two or more decorative pieces, the decorative pieces fall apart, making it difficult to arrange the separated decorative pieces in a desired state.

(Problems to be Solved by the Invention) As described above, this invention is troublesome to manufacture, and when the intricate design is minute, it is almost impossible to obtain an accurate pattern, and furthermore, it is impossible to obtain an accurate pattern. This aims to solve the problem that it is difficult to arrange a pattern having two or more separate parts in a desired state.

Structure of the Invention (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention forms an electrodeposited layer by electroforming on a molding member in which a part of the metal plate is exposed. process, and after this electroforming process, a process of attaching an adhesive film to the electroformed surface of the molding member and then peeling it off from the molding member together with the electrodeposited layer to form a decorative piece. and, after this peeling step, a step of adhering the decorative piece to release paper together with an adhesive film.

(Function) The present invention adopts the above-mentioned structure, and the electrodeposited layer formed on the metal plate exposed from the molding member is peeled off together with the adhesive film to become a decorative piece.

(Example) Hereinafter, one embodiment of the present invention will be described in detail with reference to all the drawings.

Among the drawings, FIG. 1 shows the entire molding member 1;
2 is a metal plate such as a copper plate or a stainless steel plate, and 3 is a resin layer fixed on the metal plate 2. To describe in detail the method for manufacturing the molding member 1, as shown in FIG. After forming a resin layer 3 by coating and drying a resist (using a resist), the entire positive 3a for black and white photography is placed on the same resin M3. The positive 3a is obtained by photographing a desired pattern 4 in advance and then developing it, as shown in FIG. 3, for example.

After placing the positive 3a on the resin layer 3, place the positive 3a from above.
irradiate it with strong light from an arc lamp or mercury lamp. In this exposure process, the light emitted from an arc lamp etc. is a positive 3
The transparent part 5 (the part where the emulsion is fixed) reaches the resin layer 3 through the transparent part 5 (the part where the emulsion is fixed), and it is blocked in the opaque part 6 (the part where the emulsion has been washed away) and does not reach the resin layer 3. Therefore, the resin In the layer 3, exposed areas and unexposed areas are formed corresponding to the transparent areas 5 and opaque areas 6 of the positive 311.

After this, remove the positive 3af from the resin layer 3 and add white kerosene, 1
- Treat the resin layer 3 with a solvent such as 11 chlortyrene.

2. That is, by dissolving and removing only the unexposed portion of the resin layer 3, a recess 2a is formed and the metal plate 2 is exposed,
It has an uneven surface corresponding to the shape of the pattern 4 of the positive 3a. Forming the mold member 1 - The mold part b'iu constructed as described above is immersed in a 2% solution of chromic acid for about 30 seconds, and then washed with water. Then, as shown in FIG. 4, the concave m2a of the molding member 1 is exposed! 118-r, a thin chromium coating 7 is fixed on the surface of the metal plate 2. This film forming step is carried out in the same manner as the usual chromate treatment to smooth the surface of metal materials, but in this example, the electrodeposited film is formed on the molding member 1 by electroforming treatment, which will be described later. This is done to facilitate peeling off of the layer 11.

After forming the peeling film 7 in the recess 2a of the molding part 1,
Next, as shown in FIG. 5(a), the mold member 1 is subjected to an electroforming process in an electrolytic solution 9 in an electrolytic solution tank 8. The electrolyte solution 9
is formed by mixing 240 f/(l) of copper sulfate, 9(1/e) of sulfuric acid, and a trace amount of brightener (in this example, Cataracid CU from Okuno Pharmaceutical Co., Ltd. is used), and the same electrolyte. By passing an electric current between the electroforming material 10 such as Nitsu 7/L' material dipped in 9 and the molding member 1, the molding member 1 is formed as shown in Figure 1 (1)). Electrodeposition layer 11 is attached to recess 2a.

The current value at this time is IA per 10,000 meters of the exposed part of the metal plate 2 in the recess 2a of the molding part shrine 1,
Furthermore, the metal plate 2 exposed on the entire non-electroformed surface of the molding part 1
The back side has been lacquered in advance to make it non-electrodepositable.

After confirming that the electrodeposited layer 11 has been adhered to the molding member 1, the molding member 1 is taken out from the electrolyte bath 8 and dried with warm air. When the molding member 1 is completely dry, a transparent adhesive film 12 made of synthetic resin is pasted on the electroformed surface of the molding member 1 as shown in FIG. 6, and then as shown in FIG. , the adhesive film 12 is peeled off from the molding member 1 together with the electrodeposition layer 11 . At this time, the electrodeposition layer 11 in the recess 2a of the molding member 1 is removed by the action of the release film 1.
It is easily peeled off from the metal plate 2 exposed inside, and the positive 3
A decorative piece 13 having a shape corresponding to the pattern 4 of a is attached to the adhesive film 12.

After the adhesive film 12 is peeled off from the molding member 1, an adhesive is applied to the back surface of the decorative piece 13, and both 12 and 13 are adhered to the surface of the release paper 14 as shown in FIG. The surface of the release paper 14 is waxed or siliconized so that the adhesive film 12 can be easily peeled off later. Therefore, when it is desired to use the decorative piece 13 by pasting it on an object such as a passenger car, the release paper 14 and the adhesive film 12 are used.
What is necessary is to peel off the adhesive film 12 together with the decorative piece 13 and attach it to the object, and then peel off only the adhesive film 12 from the object.

In this embodiment, the pattern 4 is formed by a pair of decorative pieces 13 arranged on the left and right and separated from each other.
Since it is formed by transferring the adhesive film 11 to the adhesive film 12, it can be attached to the object without disturbing the relative positional relationship between the two 13.

Moreover, since the decorative piece 13 is finished into a desired shape by electroforming, even a detailed design can be formed accurately.

Furthermore, manufacturing is simple because no process other than electroforming is required to form the decorative piece 13.

Note that the present invention is not limited to the embodiments described above; for example, the electroforming material 10 may be made of gold, silver, chrome, etc. instead of nickel/l/, and the color of the decorative piece 13 may be As long as it does not deviate from the purpose of the invention, such as by changing the feeling etc. Any changes are possible in ll.

Effects of the Invention As detailed above, the present invention includes a step of forming an electrodeposited layer 11 by electroforming on the molding member 1 with a part of the metal plate 2 exposed, and a step of forming the electrodeposited layer 11 after this electroforming step. An adhesive film 12 is attached to the electroformed surface of the molding member 1, and this is peeled off from the molding member 1 together with the electrodeposition m11 to form a decorative piece 13.
The manufacturing process is simple, and even fine patterns can be formed accurately. Moreover, even separated patterns can be arranged in a desired state, which is an excellent effect.
