Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method for forming precious metal images such as gold, silver, platinum, etc. on ceramic products. Methods of applying precious metal tomoe to ceramic products include mixed liquid (water and gold), platinum liquid, silver liquid, etc.
9r, a method of drawing with a fine brush or a rubber stamp, and a method of direct printing using a shell metal organic substance blend base) or a method of slide transfer.

Conventionally, in the case of the slide transfer method [Prize S4 organic compound paste is made of precious metals such as gold and platinum. It is formulated with solvents such as natural resins such as turpentine, vegetable essential oils such as turpentine, ethers such as butyl seron luhe, and esters such as amyl acetate.Use such paste trays for screen printing, etc.↓9 Transfer paper (Water-absorbent paper fully coated with dextrin), after drying, cover the image with a solvent-based cover coat (top coat), after cn2 drying, immerse in water, and remove the separated cover coat. Slide transfer the image onto the ceramic product,
It was being fired. However, in the above-mentioned method, the drying time of the printed transfer paper becomes long due to the mixing of medium-to-high boiling point solvents, and the drying area and area become large. Directly layer Ikenomisai paste ink tJiQ t) Mix and dry:■
Because the time is long, the movement to the next EnerA is slow and inefficient.Also, if the low boiling point bath is used for 11 sessions,
There is no paste stability due to the evaporation of the -6 agent, resulting in rough edges during printing, and even if the drying time can be shortened, good images cannot be obtained.

Moreover, after printing width 1, the image is covered with cover coat 7, but the remaining solvent adversely affects the firing atmosphere, and the color development and gloss of the image due to the mixture of the remaining solvent and the cover coat solution 11. C. There were defects that caused negative effects. father,
Environmental by the vaporization of solvent? 4? They also have some birth defects.

Therefore, in order to remove the above-mentioned defects, this invention
? In this method, an image sound is formed on a ceramic product by using an ultraviolet curable resin R without using IW.

μ [, An embodiment of the present invention will be described in detail.

The above-mentioned paste for gold and platinum 6 is an example of a composition for hardening with ultraviolet rays without using a solvent according to the present invention. By adding all of the commercially available 7 Lacs (Glass 1 Compliment Agent), a matte precious gold sail organic compound base can be obtained. Nonoradium can also be used as the precious metal instead of platinum. Thus, the matte golden 4 organic compound paste I/i
It is as follows.

First example paste io.

Gold powder (average particle size 1 micron) 7. Flux (commercially available glass adhesive) 1. Stamp the image on transfer paper using the above-mentioned 4 organic compound blended paste χ, and harden it with ultraviolet light (this base). UV hardening “H type fA” is applied on the cured image.
Oil formulation (dog coat) or commercially available synthetic resin formulation (solvent type top coat) t cover coating and transfer paper? obtain. This transfer paper is immersed in water, and the transfer paper is dissolved by water absorption from the back side of the mount, and the 18 image is peeled off together with the top coat.

This fl-7r was transferred onto a ceramic product by sliding it, and after being completely dried, the top coat was burned out.
Kiln - 6 The desired image of gold, silver, platinum and other gold films is obtained on the product. Of course, in the formulation)-iit
is burnt out during formation, bismuth and chromium increase in the genus N, and rhodium and rhodium increase in luster.

As detailed above, there is no need for solvents with medium to high boiling points, the drying volume is shortened, there is no time loss due to overprinting, and it is also environmentally hygienic (as there is no residual solvent). The atmosphere in the firing furnace was good, and the paste and top coat were melted and /)
There is no mixing, and the color development and gloss of the image of the ceramic product after firing are excellent.
