Abstract

The invention provides colored fine resin particles useful as coloring materials for inks which can provide images having good water fastness, weather fastness and rub-off resistance and are excellent in dispersion stability, and a production process thereof. The colored fine resin particles have a structure in which a pigment coated with a water-insoluble resin is encapsulated with a copolymer composed of at least a polymerizable unsaturated monomer and a reactive emulsifier.
