摘要

PROBLEM TO BE SOLVED: To provide a method of manufacturing a pigment composition capable of manufacturing a high concentration resin composition for coloring which can be mixed into a vehicle for a printing ink, coating material and the like only by agitation without using a bead pulverizer, and a pigment dispersion and a resin composition for coloring which use the pigment composition to be manufactured by the method.;SOLUTION: The method of manufacturing a pigment composition is characterized in that a water soluble organic solvent solution of a water insoluble resin, a pigment, and water are mixed and depositing a composition containing the pigment and the water insoluble resin is deposited, and further, a mechanical attrition treatment is conducted in mixing the water soluble organic solvent solution of the water insoluble resin, the pigment, and water, and furthermore, an aqueous suspension of the pigment is mixed with the water soluble organic solvent solution of the water insoluble resin to effect mixing of the water soluble organic solvent solution of the water insoluble resin, the pigment, and water.;COPYRIGHT: (C)2004,JPO
