摘要:
A method for manufacturing an azoic pigment is disclosed, according to an illustrative embodiment of the present invention. The method includes producing slurry of the azoic pigment. The slurry includes primary aromatic amine (PAA). The method further includes the derivatization of the residual PAA in the slurry, followed by encapsulation of the slurry. The slurry is acidified or basified. Finally, the slurry is further processed, thereby forming PAA migration free azoic pigment. The derivatization and encapsulation additively or synergistically reduce the PAA content thereby inhibiting migration of PAA from the pigment into a substrate onto which the pigment is loaded.
