Title:

DISPERSION OF COLORED PARTICLE EXCELLENT IN WEATHER RESISTANCE

Document Type and Number:

Japanese Patent JPH06145549

Kind Code:

A

Abstract:

PURPOSE: To provide the title dispersion suppressed in the photodecomposition of the constituent halide and improved in weather resistance by mixing a solvent containing dispersed colored particles comprising a halide with a halogen of the same kind as that of the halide.

CONSTITUTION: Colored particles comprising a halide are dispersed in a solvent to obtain a colored particle dispersion of a water content of 1000ppm or below. To this dispersion are added a halogen of the same kind as that of the halide in an amount to provided a molar ratio of 0.01-5 based on the halide and optionally 0.1-20wt.% light stabilizer comprising a benzotriazole compound and/or a benzophenol compound and optionally further a hindered amine compound.
