Abstract
A coloring composition for a color filter composed of composite particles having an average particle diameter of 0.00 1 to 1.0 μm, and containing white inorganic particles, a glue coating layer formed on the surface of the white inorganic particle and an organic pigment coat formed on the glue. A dispersant, binder resin, monomer as a reactive diluent, a polymerization initiator and a solvent are also present. The colorant provides not only a sharp particle size distribution but also excellent light resistance.
