ABSTRACT:
Composite particles having an average particle diameter of 0.001 to 10.0 μm, comprise:white inorganic particles as core particles;a gluing agent coating layer formed on surface of the white inorganic particle; andan organic pigment coat formed onto said gluing agent coating layer in an amount of from 1 to 500 parts by weight based on 100 parts by weight of the white inorganic particles. The composite particles are substantially free from desorption of an organic pigment from the surface thereof and contain no harmful element.
