TREATED PIGMENT AND INK

PROBLEM TO BE SOLVED: To provide a coating-treated pigment which is easily dispersible and gives a pigment dispersion excellent in viscosity and dispersion stability, and an ink having the treated pigment dispersed therein. SOLUTION: The treated pigment is obtained by causing a reactive emulsifier b...

Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a coating-treated pigment which is easily dispersible and gives a pigment dispersion excellent in viscosity and dispersion stability, and an ink having the treated pigment dispersed therein. SOLUTION: The treated pigment is obtained by causing a reactive emulsifier bearing an acidic group to bond to a pigment which has a coloring matter derivative bearing a basic group bonded on the surface thereof and causing the reactive emulsifier to polymerize.
