Abstract
The synthetic mixed pigments of Lithol Rubine were prepared throught cocoupling reaction of two diazo-constituent or two coupler. The measure of colour property showns that: most of synthetic mixed pigments exhibit synergistic action. It was found that change of dispersive state is one of important reasons of syneigism of pigment.
