Colored composite microparticles, process for producing the colored composite microparticles, colorant, color filter and ink for ink-jet printing

摘要

Colored composite microparticles comprising silica and an organic pigment in which the silica is enclosed in the organic pigment and contained in an amount of 0.001 to 9% by weight (calculated as Si) based on the weight of the composite particles. These microparticles have a high tinting strength and are excellent in dispersibility and light fastness.
