Process for the production of readily dispersible pigment preparations |
摘要 |
A process for the production of readily dispersible pigment preparations with a pigment content of more than 65% is disclosed. An aqueous suspension containing 25% to 50% by weight of a pigment is made and kneaded with heating to 60 DEG -70 DEG C. Following addition of a cation-active substance and an oleate, a binder dissolved in an organic solvent is added and a phase inversion takes place whereby water is separated out. After decantation, the organic mass of pigment is kneaded and dried.
