<p><P>PROBLEM TO BE SOLVED: To provide a method of atomizing an organic pigment which can be commercialized cost-wise in a simple step and is endowed with solidness and surface treated organic pigment particles. <P>SOLUTION: The surface treated organic pigment particles has an organic pigment particle base (A) and a metal-containing gel layer (B) which contains a fluorine-containing metal alkoxide to cover the surface of the organic pigment particle base and is formed by the sol-gel reaction of the metal alkoxide. The surface treated organic pigment particles have fine primary particles and excel in solidness (for example, light resistance, heat resistance, oil resistance, chemical resistance, solvent resistance, bleeding resistance, and migration resistance), and are also high performance nanopigments which show dispersibility with good stability by avoiding a strong aggregation of the pigment particles. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
