PROCESS FOR THE PREPARATION OF PIGMENT COMPOSITION FOR DYEING VARNISH-AND-PAINT AND POLYMERIC MATERIALS

摘要

A pigment solid composition for dyeing varnish-and-paint and polymeric materials of mixture of pigment compounds with further separation is characterized in that it is prepared of compounds of general formulae (I) and (II) in weight ratio of 1:10-10:1, its surface is modified with carboxyl-containing oligoether of general formula (III) or complex of carboxyl-containing oligoether salt with macrocyclic crown-ether dibenzo-18-crown-6 or 18-crown-6, or 15-crown- amount of 2-5%, and a process for the preparation of pigment solid composition is carried out in medium of concentrated sulphuric acid in amount of 1:1-9 weight part per 1 weight part of organic pigment compounds at 80-.
