Description

DETAILED DESCRIPTION OF THE INVENTION "Industrial Application Field" The present invention uses electrolysis to fix only images such as individual characters, figures, patterns, etc. on adherends. The present invention relates to a method for producing an electrodeposited image with an adhesive, in which only an electrodeposited image is formed and an adhesive is attached to the electrodeposited image.

``Prior art'' Conventionally, parts of a metal plate other than the required image are coated with insulation, and the non-insulated areas are electrodeposited by electrolysis to form an electrodeposition image of a thin metal film, which is transferred to a film, and then Apply adhesive to the electrodeposited image after transfer, leave it as it is, or paste release paper on the adhesive side and peel it off before use, and then stick the electrodeposited image to the adherend using the adhesive. The film is peeled off from the electrodeposited image and fixed with adhesive.

In the above method, it was very difficult to apply adhesive only to the electrodeposited image.

Therefore, the invention disclosed in Japanese Patent Publication No. 63-18674 covers the metal plate with insulation only in the vicinity of the image, excluding the necessary image, and electrodeposit the entire metal plate by electrolysis method. The thin film of the image, i.e.
A mask is formed to prevent adhesive from adhering to the electrodeposited image and a metal plate around the image, a film with adhesive is attached to the metal plate and peeled off, and the electrodeposition image and mask are transferred to the film. Then, spray a strong adhesive onto the electrodeposited image transferred to the film, remove the mask, and paste only the electrodeposited image on the adherend directly or after pasting it on release paper. As a result, the adhesive can be easily applied only to the desired image, and an electrodeposited image with less edge effect can be obtained due to the well-known auxiliary cathode effect.

"Problem to be Solved by the Invention" If the above-mentioned mask is formed at the same time as the required image, if the required image is a character, the area ratio of the character on the metal plate is extremely small; In comparison, a much larger proportion of the electrodeposited area is formed as a mask, and the mask is discarded after the adhesive has been applied to the image.

For this reason, a large amount of electric power is required for electrolysis, and a large amount of metal material for electrodeposition formed on the mask is required, resulting in an increase in manufacturing cost. Even if the electrodeposition metal material used in the mask were to be recovered and reused, it would be expensive to reuse it, which would increase the manufacturing cost in any case.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a simple and inexpensive method for producing an electrodeposited image with an adhesive by an electrolysis method while maintaining quality.

"Means for Solving the Problems" A first aspect of the present invention is to apply an insulating coating to a portion of the metal plate other than a necessary image and a linear auxiliary cathode portion that is close to and surrounds the image; Electrodeposition is performed on the non-insulated part of the metal plate, the insulating part is removed, and the adhesive side of the sheet coated with a weak adhesive is pasted on the metal plate and then peeled off. Peel off the deposited part from the metal plate, remove only the electrodeposited part on the auxiliary cathode part from the sheet, and use a mask with an opening slightly larger than the image to remove the image on the sheet. Cover the area and apply adhesive to the electrodeposited area of the image.

This is a method for producing an electrodeposition image.

A second invention of the present invention is a method for producing an electrodeposited image according to the first invention, wherein a release paper is pasted on the side of the electrodeposited portion of the image coated with an adhesive.

"Example" Hereinafter, an example of the present invention will be described using the drawings. As shown in FIGS. 1A and 1B, an electrodeposition film 1 and a mask film 2 used for adhesive application are created as image patterns by photography, printing, or the like. In the figure, the symbol 3 illustrated as ABCDE is a required image (hereinafter simply referred to as an image). 4 is a linear auxiliary cathode image surrounding the image 3 near the image 3; an auxiliary cathode image 4 surrounding one image 3 and an auxiliary cathode image 4 surrounding the image 3 adjacent to the image 3;
are connected by the connecting part 4a to form a single stroke and a closed shape, which improves the workability when removing the electrodeposited part electrodeposited on the auxiliary cathode made using the auxiliary cathode image 4. preferred for. The thinner the thickness of the auxiliary cathode image 4 is, the more economical it is, as long as it does not tear off when removing the electrodeposited part on the auxiliary cathode made using the auxiliary cathode image 4. Thinness is also limited to prevent wear.

On both sides of the image 3, installation guide mark images 5 are printed or photographed to create an electrodeposited part to be placed at a certain position on the adherend to fix the electrodeposited image on the thin plate that will be formed later from the image 3. Alignment guide mark images 6 are provided at the four corners of the film 1 to form electrodeposited portions for alignment with a mask, which will be described later, made using the mask film 2.

The mask film 2 is provided with a transparent window 8 that is slightly larger than the image 3 and surrounds the image 3 close to its periphery when superimposed on the electrodepositing film 1.
In addition, the mask film 2 is a sheet made from the electrodepositing film 1 in a subsequent process.
In order to accurately overlap the masks made in the subsequent process, an alignment guide mark image 9 is provided at the same position as the alignment guide mark image 6 provided on the electrodeposition film 1. The mask film 2 is black and opaque except for the transparent window 8 and the alignment guide mark image 9.

First, a method for manufacturing a mask using the mask film 2 will be described. Using the mask film 2, a transparent window 8 is formed on a metal plate 21 by photography or printing.
When the insulation coating 22 is applied at the position (FIG. 2) and electrodeposition is performed on the metal plate 21 (FIG. 3), the electrodeposition is applied to areas other than the insulation coating 22, and the electrodeposited portion ²⁵¹ is peeled off from the metal plate 21. As shown in FIG. 4, a mask 25 is completed in which an opening 23 corresponding to the transparent window 8 and a matching hole 24 corresponding to the matching guide mark image 9 are formed.

〔Effect of the invention〕

Since the present invention has a method for producing an electrodeposited image with adhesive as described above, the main thing that is discarded at the electrodeposition section is the metal electrodeposited on the auxiliary cathode, but this part is completely disposed of on the metal plate or transparent film. The area is small compared to the area, the amount of metal used for electrodeposition is extremely small, the power consumption during electrodeposition is small, and the time required for electrolysis is short, making it economical. Incidentally, since the mask used is one that is used repeatedly, the above-mentioned economical efficiency is not hindered.
