Abstract

The invention relates to a pigment dispersion method, a pigment mixture, light-cured ink and thermo-cured ink. The pigment dispersion method comprises the steps of: mixing 0.05-20wt% of dispersion resin and 5-10wt% of solvent in a stirring way, and preparing dispersion resin solution; mixing 1-20wt% of dispersing agent and 15-20wt% of solvent in a stirring way, and preparing dispersing agent solution; adding 5-20wt% of pigment to be dispersed into the dispersing agent solution, and preparing first mixed solution; adding the dispersion resin solution into the first mixed solution, and preparing second mixed solution; adopting 20-55wt% of solvent to dilute the second mixed solution; and using a sand mill to grind and disperse the second mixed solution which is evenly diluted. The invention has the advantages of small grain diameter, narrow range of grain fineness distribution, low viscosity, excellent wettability, high storage stability and the like.

Description

technical field

[0001] The invention relates to a pigment and a preparation method of the pigment, in particular to a pigment dispersion method, a pigment mixture, light-curable ink and heat-curable ink. Background technique

[0002] In recent years, with the continuous improvement of consumers' requirements for products, producers are also continuously improving their product performance and precision levels. Taking the field of ink technology as an example, with the promotion and popularization of inkjet printing technology, consumers require inks to have bright colors, low viscosity, good fluidity and good storage stability, so correspondingly require pigment mixtures (also known as pigments) Dispersion system) has the properties of small particle size, narrow particle size distribution, low viscosity, stable storage and so on.

[0003] The pigment used as the coloring system in the ink and pigment photoresist is dispersed in the coloring body in the form of micronized p...
