The color of the metal sticker depends solely on the plating metal (for example, gold or silver, etc.), so it is limited to gold, silver, or similar metallic gloss. Bar, there was a problem that it is difficult to express a variety of colors desired by the user.

As an attempt to express the metal sticker in various colors, a method of painting a sticker plate formed by nickel electrodeposition has also been attempted as described above, but this is cumbersome because it has to be made through a separate process after the creation of the sticker plate, and also a manufactured color. There was a fear that the color of the pattern peeled off. In addition, as described above, the sticker plate is mainly to be attached to an object that requires a relatively sophisticated and luxurious expression, such as a wristwatch or an ornament, whereas the sticker plate is neatly processed by painting Has been difficult to meet the demand for the manufacture of metal stickers with higher aesthetics. In addition, the conventional metal stickers had a limit of application as a decorative member of the article rather than a functional element. Recently, the decorative beauty of the product is enhanced, and at the same time, the counterfeit / counterfeit prevention in terms of functionality, recognition of outdoor advertisements / There has been a demand for a metal sticker that can serve as an identification mark and an antenna of RFID attached to a product.

Hereinafter, with reference to the accompanying drawings, a method of manufacturing a metal sticker according to the present invention will be described in detail.

1 is a cross-sectional view of a stainless plate in order to produce a metal sticker in accordance with the method of the present invention, the process of electrodepositing the letters on the surface of the stainless plate and the process of separating the prepared letters from the stainless plate in the form of a sticker It is a block diagram shown as a reference.

As shown in Fig. 1 (a), first, a stainless steel plate 10 having a thickness of about 0.5 mm is preferred and the surface thereof is evenly and smoothly polished and washed, and then evenly disposed on the stainless steel plate 10 as a whole. The developer is applied to form the developer layer 20.

As shown in Fig. 1 (b), a film 30 having a certain pattern is formed on the developer layer 20, and then developed by exposing it. The exposure may preferably be made using a halogen lamp on the order of 30 to 35 lux, but is not limited thereto. You may use any of the normal developing solutions used at the time of printing.

After developing as described above, the film 30 is removed, and the developed stainless plate 10 is placed in a release bath to release the developer, and the developer is not erased from the lighted portion, and the developer is not removed from the light. Therefore, as shown in Fig. 1 (c), a portion of the upper portion of the stainless plate 10 is protected by the developer layer 20, and the remaining portion of the stainless plate 10 is exposed according to the pattern formed on the film. .

As described above, the stainless plate in which the developer remains only in a specific portion is washed with water and submerged in the nickel electrolytic solution. According to a preferred embodiment of the present invention, the solution may be made of nickel as the anode, and include nickel sulfate, nickel chloride, and boric acid. When the developed stainless plate is immersed in the nickel electrolytic solution and a predetermined voltage is applied at a predetermined temperature for a predetermined time, nickel of the anode melts into ions and nickel electrodeposition occurs on a portion 10a of the stainless plate not coated with the developer. . Therefore, if the stainless plate is taken out of the solution after a certain time, the nickel electrodeposition layer 40 is formed on the portion 10a that is not protected by the developer layer 20, as shown in Fig. 1 (d). .

After washing the plate removed from the nickel electroforming solution, it is submerged into a metal salt containing electroforming solution containing various metal salts for coloring. The metal salt-containing electroplating solution may include any one as long as it can be electrolyzed to produce metal ions having various colors, but as described above, preferably, lead, zinc, sodium, gold, copper, potassium and chromium ions. It consists of a solution of a metal salt compound capable of producing one or two or more various metal ions selected from the group consisting of, to promote the redox reaction by electrolysis, as well as glacial acetic acid, boric acid, sulfuric acid And acids such as potassium phosphate or acid salts thereof. The solution may also use nickel, platinum, lead or stainless as the anode depending on the desired color.

By applying a constant voltage to the metal salt-containing electroforming solution, the metal material constituting the positive electrode plate melts into the solution in the form of ions. The molten ions undergo a redox reaction in accordance with the difference between the standard reduction transition and the other metal ions present in the metal salt-containing electrolytic solution, thereby forming a specific color on the nickel electrodeposition layer 40 formed in the previous step (50). ) Will be electrodeposited.

When taking out the stainless plate subjected to the coloring process under a predetermined temperature, time and voltage, as shown in Figure 1 (e), a metal electrodeposition layer 50 having a specific color is formed on the nickel electrodeposition layer 40. The voltage to be applied and the voltage application time will vary depending on the type of metal salt contained in the applied electrode solution, but in general, the voltage application time for electrodeposition of metal ions is very short compared to the nickel electrodeposition time. The reason is that electrodeposition of metal ions is sufficient to sustain the reaction only to the extent that the color of the particular metal is electrodeposited onto the plate already formed.

When the plate on which the metal electrodeposition layer 50 is formed is taken out of the metal salt-containing electroplating solution and submerged in the degreasing solution, the remaining developer is completely degreased, and the nickel electrodeposition layer on the stainless plate 10 as shown in FIG. Only 40 and the metal electrodeposition layer 50 formed thereon remain. The electrodeposition layer forms a predetermined pattern according to the character or figure that was designed on the film.

In order to manufacture the pattern of letters or patterns in the form of a sticker, a transparent protective paper 60 coated with an adhesive is attached onto the electrodeposition layer, and then the stainless plate 10 is carefully peeled off and separated. A transparent protective paper 60 is attached to the upper electrodeposition layer, and FIG. 1 (g) shows a state where the stainless plate below the electrodeposition layer is separated.

In FIG. 1 (g), when the adhesive is applied again to the lower surface 40a of the electrodeposition layer having the transparent protective paper 60 attached to the top, and the release paper 70 is attached thereto and cut to size, it is shown in FIG. 1 (h). The metal sticker according to the invention as shown is completed.

Now, the metal stiffened in this way, by first peeling off the lower release paper 70, if necessary, by placing the letter in the desired place, the adhesive, and then detaching the transparent protective paper 60 attached thereon, The letters and patterns can be easily and neatly attached to watches and other elaborate ornaments.

As described above, the present invention is characterized by producing a metal sticker of various colors by electrodeposition by using a metal salt solution capable of generating metal ions that can exhibit various colors by redox reaction by electrolysis. do.

In the series of processes, the types of metal ions capable of expressing various colors are not limited to the above, but more various, in order to ensure that the metal ions are well electrodeposited on the nickel electrodeposited plate, the standard metal transition reduction value between the metals In consideration of this, an appropriate anode and metal salts may be selected and combined to prepare a coloring solution. Furthermore, those skilled in the art will be able to easily select and carry out a reaction temperature, time, and voltage in a suitable range so that it can be well electrodeposited on the stainless plate, depending on the type of metal ion selected. Therefore, depending on the type of metal ion, the temperature, time, and voltage suitable for causing a redox reaction may all vary, but at a temperature between 30 ° C. and 80 ° C., a voltage between 0.4 V and 10 V may be applied. The reaction is allowed to proceed until electrodeposition.

Multi-deposited metal sticker according to another aspect of the present invention, as mentioned above, can be made by repeating part of the manufacturing process of the metal sticker according to the present invention.

That is, a developer is applied to a polished and washed stainless plate, the first film having a pattern formed thereon is developed and developed, and then primary nickel electrodeposited in a nickel electroforming solution. The nickel-deposited plate is taken out, the remaining developer is removed, washed with water and dried, and then the developer is applied over the plate as a whole. It develops by putting the 2nd film which another form designed here. A double electrodeposited metal sticker can be produced by subjecting the developed plate to nickel electrodeposition in the nickel electroforming solution again. Furthermore, after the developed stainless plate is washed with water and dried, the developing solution is applied as a whole, and a third film having a pattern different from the patterns of the first and second films is placed thereon, and the developed plate is developed. Multiple electrodeposition metal stickers may also be prepared by electrodeposition again in a nickel electroforming solution.
