Problems solved by technology

[0002] At present, the formula of commonly used laser water transfer decal paper color coating is mainly phenolic resin. Due to the high temperature resistance of phenolic resin, its brightness is not high enough for laser imprinting, so it cannot meet the production needs.
Therefore, the existing technology increases the embossing brightness by increasing the embossing brightness of the laser water transfer decal paper color coating, and increases the embossing brightness by the resin proportion in its formula. However, the hot stamping of the laser water transfer decal paper color coating after the formula adjustment Speed, fastness, cutting surface, adhesion and other related functions are easy to change, which makes the transfer effect of post-processing uncontrollable
Moreover, in the control of the coating process of laser water transfer decal paper color layer coating, the production conditions are also changed due to the change of the color layer formula, which greatly reduces the production efficiency

Abstract

The invention relates to the technical field of laser water transfer-printing stained paper color layers and particularly relates to laser water transfer-printing stained paper color layer coating as well as a preparation method and an application thereof. The laser water transfer-printing stained paper color layer coating is prepared from the following components in percentage by weight: 15%-20% of phenolic resin, 0.5%-1% of methyl acrylate, 0.5%-1% of n-butyl acrylate, 0.2%-0.6% of methyl methacrylate and 78%-83% of absolute ethyl alcohol. A certain amount of methyl acrylate, n-butyl acrylate and methyl methacrylate is used for preparing the phenolic resin, so that the tolerable temperature of the prepared laser water transfer-printing stained paper color layer painting is lowered, and therefore, the embossing brightness of the laser water transfer-printing stained paper color layer coating can be greatly increased during laser embossing, and the production needs can be met. Moreover, the laser water transfer-printing stained paper color layer coating can be used for ensuring that associated functions such as embossing speed, firmness, section and adhesion are not changed, so that the production efficiency can be improved.
