Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is directed to the production of gold and silver plated transfer paper that transfers a three-dimensionally raised gold and silver pattern onto the surface of ceramic products such as ceramics, glass, and enamel by scattering and fixing gold and silver powder. Pertaining to law.

Gold and silver patterns formed from gold or silver powder have a noble color and are prized, but they are not suitable for printing and cannot be attached to the surface of ceramic products and fixed by baking. A supporting pattern is printed using a varnish that acts as a binder, and while it is still wet, gold or silver powder is sprinkled and fixed, and after drying, the unnecessary portions of the gold and silver powder are removed to reveal the pattern. It is something that exists.

However, since there is no pressure varnish layer in this conventional method, the pattern is easily damaged during cleaning, and when forming a cover coat on top of the gold and silver pattern using the screen printing method, or when combining other colors with printing, the pattern is easily damaged. The drawback was that it easily caused clogging, making printing difficult. The present invention eliminates such drawbacks, and uses a screen printing method to form a cover coat that is applied to prevent the gold and silver pattern from being damaged by cleaning work and to prevent the pattern from collapsing when transferred from the mount to the transferred object during slide transfer. Everything has been streamlined so that printing can be easily performed without clogging the screen with gold and silver powder when printing or printing with other colors.

An embodiment of the invention will be described with reference to the accompanying drawings.

1st step Water-soluble pigments are prepared on the water-absorbing mount 1 by kneading pigments and adjusting the color tones such as white, yellow, and green, and using ceramic printing ink that has a binder effect for adhering metal powder. On the glue layer 2, there is a 30μ to 50μ ink mound larger than the normal printed pattern (the normal pattern is 15μm).
μ~20μ).

(Figure 1). Second step: While the support pattern 3 is not dry, gold powder or silver powder a is sprinkled to form a gold and silver pattern 4 that adheres to the surface of the pattern 3.

(Figure 2). Third step: After the ink of the support pattern 3 dries and the gold and silver pattern 4 is fixed, a fluid ``vehicle'' is printed on the pattern 4 to a thin thickness of 5 μm or less.

Due to its fluidity, the vehicle also flows to the side edges of the gold and silver pattern 4, forming a holding vehicle layer 5 that almost covers the gold and silver pattern 4. (Figure 3). j Fourth step After the presser layer 5 is dried, the gold and silver powder in unnecessary parts is removed to reveal the gold and silver pattern 4.

(Figure 4).

Continuing to the fifth step, a pattern-supporting cover coat 6 is printed on the required area of the mount 1 to cover the gold and silver pattern 4.

Is the cover coat a petroleum-based mixture of acrylic resin? A known cover coat material is used which has been treated with a chemical agent. (Figure 5). As clarified in the description of the above embodiments, the method of the present invention is to form a raised support pattern 3 using pigment-mixed ink in large ink mounds, and then sprinkle gold and silver powder to adhere to the support pattern 3. A fixed gold and silver pattern 4 has a three-dimensional raised pattern, and the raised support pattern 3
Even if it is heated to the baking temperature of the gold and silver pattern 4 and burns off the organic content in the ink, the pigment will not be burned out, so it will be baked into the surface of the transfer object in a ridged shape and the gold and silver pattern 4 will also be formed. Fixed by baking.

Therefore, the gold and silver pattern 4 has a three-dimensional shape that directly follows the shape of the three-dimensional pattern of the raised support pattern 3, and there is no possibility that the pattern will be crushed due to internal hollowing, making it impossible to express the pattern. In addition, the raised support pattern 3 can be made into any color by using pigments mixed with the ceramic ink used to print it, so as it is printed, it is colored with a mixed color that is a mixture of the original bright colors of the gold and silver powder of the gold and silver pattern 4. can be applied to produce, for example, a white-ish gold color, a green-ish silver color, etc., thereby enhancing the color mixing effect. However, the gold and silver powder that adheres to the surface of the raised support pattern and forms the gold and silver pattern 4 has some parts that are unstable in adhesion and fixation, and is peeled off when unnecessary parts are cleaned, causing the pattern 4 to be partially damaged. The printing of the cover coat 6 may cause obscurity or cause clogging due to the eyes of the screen when the cover coat 6 is printed by screen printing means, thereby reducing the strength of the cover coat 6. Since the holding vehicle layer 5 is formed before forming, the gold and silver powder of the gold and silver pattern 4 does not scatter even if the unnecessary part of the gold and silver powder is vigorously cleaned. The amount of collection can be improved, and the gold and silver patterns 4 will not be damaged. Furthermore, the cover coat 6 can be formed accurately by preventing clogging of the screen by the holding vehicle layer 5, and can bring about excellent effects in terms of manufacturing and printing.

Claims (1)

[Claims] 1 A raised support pattern 3 with a larger ink buildup than a normal printed pattern is printed on a water-soluble glue layer 2 provided on a water-absorbing mount 1 using a pigment-mixed ink having a binder effect, and the pattern 3 is left undried. In between, gold powder is sown to form a gold and silver pattern 4 that covers the raised support pattern 3, and after the gold and silver pattern 4 is dried, a presser vehicle layer 5 is thinly overprinted and further dried.
The method for producing gold and silver plated transfer paper is characterized in that the unadhered gold and silver powder in unnecessary parts is then swept away and a pattern-supporting cover coat 6 is applied.
