    摘要： There are provided colored composite microparticles having a fine primary particle diameter and exhibiting a high tinting strength, an excellent dispersibility and an excellent light fastness; a process for producing the colored composite microparticles; and a dispersion of the colored composite microparticles. The colored composite microparticles are composite particles 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. The coloring composition for color filters is prepared by dispersing a colorant for color filters comprising the colored composite microparticles in a coloring composition base material, whereas the ink for ink-jet printing is prepared by dispersing a colorant for inks for ink-jet printing comprising the colored composite microparticles in an ink base solution. The colored composite microparticles have a high tinting strength and are excellent in dispersibility and light fastness, and therefore, can be suitably used in various applications such as ordinarily used paints, printing inks, etc., irrespective of an aqueous system or a solvent system.
