Problems solved by technology

However, the solvent resistance of the dye is poor, and its color is easy to precipitate when it encounters a solvent, which makes the bronzing products prone to the problem of color fading during production and use.
In order to solve the problem that the color is easy to fade, the existing technology will increase the percentage of dye used, but if the percentage of dye used is high, the surface quality of bronzing coating will be relatively poor after coating
[0003] Compared with dyes, pigments have better heat resistance, weather resistance and solvent resistance, and the product has high color brightness, but pigments are used in bronzing coatings. It will make the bronzing products have poor light transmittance, thus making the bronzing products lack of market competitiveness

Abstract

The invention relates to the technical field of gold stamping coatings, and in particular relates to a gold stamping coating and a preparation process thereof. The gold stamping coating comprises acrylic resin, an organic pigment, a metal complex dye, butanone, methyl isobutyl ketone and a dispersant. The preparation process of the gold stamping coating comprises the following steps: I, dispersing the organic pigment into the acrylic resin to obtain a pigment dispersion; II, uniformly mixing butanone and methyl isobutyl ketone; III, slowly adding the pigment dispersion into a mixed solvent in a container while stirring at a low speed, and increasing the stirring speed while adding to obtain first color paste; IV, adding the metal complex dye into a mixed solvent to obtain second color paste; V, mixing the first color paste and the second color paste, and stirring uniformly to obtain third color paste; VI, adding the third color paste and the dispersant into the acrylic resin, and stirring uniformly to obtain the gold stamping coating. The gold stamping coating has the advantage of high solvent resistance, and can be used for increasing the transmittance of a gold stamping product.

Description

technical field [0001] The invention relates to the technical field of bronzing paint, in particular to a bronzing paint and a preparation process thereof. Background technique [0002] In the hot stamping printing industry, color is an important factor affecting the appearance quality of hot stamping products. In the prior art, since dyes are easy to dissolve and have better transparency (transparency, that is, the degree of light transmission) after dissolution, dyes are commonly used as toners in bronzing coatings. However, the solvent resistance of the dye is poor, and its color is easy to precipitate when it encounters a solvent, which makes the bronzing product prone to the problem of color fading in the process of production and use. In order to solve the problem that the color is easy to fade, the existing technology will increase the percentage of the amount of dye, but if the percentage of the amount of dye is high, the surface quality of the bronzing paint after ...
