AI Technical Summary

Technical Problem

Existing technologies make it difficult to prepare stable pigment dispersions at high temperatures, resulting in uneven pigment dispersion in polymers and affecting coloring effects.

Method used

A pigment dispersion is formed by using a pigment dispersion containing ethylene glycol or ethylene glycol oligomers as a solvent, adding a material with a boiling point higher than that of the solvent, combining a salt of specific dispersants P and X, and heating at high temperature to the solvent boiling temperature.

Benefits of technology

The pigment was uniformly dispersed in the polymer at high temperature, which improved the stability and coloring effect of the colored polymer.
