Abstract

A substrate of ceramics or metal is coated with a thermosetting resin, and it is applied to transfer painting by heating and pressing. Butanolized melamine resin of a low degree of polymn. is prepd. by adding butanol at the condensn. of melamine formaldehyde resin. A convex printing layer is formed by screen painting a substrate coated with butanolized melamine resin. The convex printing layer is half-hardened by heating at 100≰C for 4 - 5 min. Then a transfer sheet is covered and pressed down by a rubber pad.

How to transfer prints of gold and silver on a candle or metal surface

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer printing method for transferring iron or gold and silver onto a surface of a candle or metal material. In the case of the glass or metal material, there was an oil film on the surface, and the surface melting of the transferred object, which was essential for the transfer printing, did not reach the adhesive melting state of the transfer paper, and thus, the transfer was not carried out.

Therefore, the transfer method printed on vegetable or metal materials was transferred by applying the glaze before applying the glaze to the transfer paper printed with the vegetable pigment and then glazing again, and in the case of gold and silver, a solvent containing pure gold or silver was used. As a result, the manufacturing process is very cumbersome and expensive, and there is a drawback of discoloration easily due to salt, moisture or gas in the air.

In addition, it is possible to print metal and gold, silver and silver foil which can give a silver effect, but also it has no inherent gold and silver luminescent effect by forming a transparent film layer on the surface after the first printing process like a candle. The sharpness of the colors was reduced and the printing process was very complicated, which also caused the price increase.

It is well known in the art that there are no other prints that are more effective than gold and silver transfer printing, especially in the case of gold and silver in print clarity.

However, such transfer printing is press-molded by applying a suitable temperature to the plastic resin layer and heat-pressing the transfer paper to the object to be transferred, whereby the shape of the mold is melt-bonded and printed on the object to be transferred. In this transfer printing process, it is obvious that the most important thing among the selection requirements of the transfer object is that the warming temperature of the mold is transferred to the transfer object, and the surface thereof is melted and melt-bonded with the adhesive of the transfer paper.

An object of the present invention is to transfer gold, silver transfer printing of iron powder on the surface of a transfer material that does not have such a requirement, that is, metal or supermaterial.

As mentioned above, the inventors experimented several times that the gold and silver foil transfer paper made of iron material is not transferred unless the molten state of the transfer object melts at the heating temperature at which the adhesive attached to the transfer paper is bonded. It became clear.

What is tested here is to transfer onto a transfer object layer which is melted on a transfer object which is not melted, and which is to be transferred and printed.

The substrate to be transferred is preferably a plastic resin which can be melted, so that the substrate is first applied to the surface of the glass or metal material through the plastic resin.

However, this process was not successful.

The plastic resin did not adhere to the oil film such as glass or metal material.

Since the plastic resin is viscoelastic, it is inadequate as an intermediate layer for transfer printing because it melts at a high temperature heated during this coloring process or loses adhesiveness.

In addition, the present invention is to transfer only a certain figure on the initial surface or the metal surface, the base layer of the plastic resin is melt-deformed by the heating pressure generated during the transfer printing process, the partial transfer printing of fine figures or characters was impossible. .

It was decided again to adopt a thermosetting resin having high hardness and not thermally deforming.

As a result, in the thermosetting resin, butanolated melamine resin containing butanol was used when condensing melamine formaldehyde reacted with melamine used as a paint and formaldehyde.

However, low polymerization degree with good heat resistance and weather resistance was adopted.

The manufacturing process of the present invention can be roughly divided into two stages: the intermediate layer printing process and the transfer printing process of the transfer paper. In other words,

Manufacturing process 1.

Low-condensation butanolated melamine resin containing butanol when condensed with melamine formaldehyde resin, using a screen printing method to print a pattern or text on the surface of the first coating film.

Manufacturing process 2.

The printed layer screen-printed with a constant pattern is heated at a temperature of about 100 ° C. for about 4-5 minutes, and the transfer sheet is covered, and the rubber pad of the plate is hot pressed before being completely cured, and then completely cured at high temperature or room temperature. Since the printed layer screen-printed with a predetermined pattern is formed more protruding than the substrate, the transfer layer is only transferred to the screen printed layer of the protruding portion by covering the transfer sheet and thermally pressing the rubber pad of the flat plate.

의 금형을 열가압하여서 전사 인쇄하는 것이므로 기판이 가소성수지로도 가능하였으나 본 발명은 전사하고자 하는 부위만이 인쇄돌출되어 있으므로 점탄성(粘彈性)의 가소성수지로는 가압순간 인쇄층이 뭉개지게되어 부적당한 것이다.What is important here is that conventional transfer printing covers transfer paper on a planar plastic resin substrate,

Since the substrate can be a plastic resin because the mold is thermally pressurized and transferred, the present invention can print out only the portion to be transferred, so that the printing layer is crushed at an instant with a viscoelastic plastic resin. It is.

In addition, the transfer printing before the intermediate print layer is cured because the melamine resin, which is a curable resin, is not deformed after being cured once and transfer printing is impossible after curing.

That is, the present invention selects the curable resin and screen-prints the substrate (curve or metal material) to protrude the print layer and apply the appropriate temperature to semi-curing the print layer to create a condition that enables transfer printing. The press of the transfer sheet using the rubber pad of the flat plate on the printing layer portion will have the gist of the process of combining only the printing layer that is the projection portion.

Thus, the present invention has a transfer printing layer is tightly printed by the hardness and adhesiveness of the melamine resin, and a slight protrusion pattern is formed, so that a beautiful transfer printing layer having superior three-dimensional and glossiness than the conventional gold and silver printing effect is provided. can do.
