Transparent, high strength organic pigments and process for making same
摘要:
High strength, highly transparent azo pigments have mean ultimate particle size of from 0.010 micron to 0.040 micron. These pigments are produced by a process in which the azo compound is reacted with a coupler in the presence of one or more of a specific group of surface active agents.
