Purification method of crude pigment and production method of pigment for low viscosity applications |
| abstract |
PROBLEM TO BE SOLVED: To provide a simple method for purifying a crude pigment and a pigment capable of lowering the viscosity of an ink while maintaining tinting strength. SOLUTION: A crude pigment is ground at 100 ° C or lower, and the ground pigment is heat-treated at 150 to 250 ° C to purify the crude pigment. Using the purified crude pigment, a pigment for low-viscosity applications is obtained by treatment under an organic solvent, water and an organic solvent or solvent salt milling. |
