Title:
塩素化銅フタロシアニン顔料
Document Type and Number:
Japanese Patent JP6662912
Kind Code:
B2
Abstract:
It is an object of the present technology to overcome the disadvantages of conventional chlorination of a copper phthalocyanine which produces copper phthalocyanine, wherein the number of chlorines is less than than or equal to 4. The pigments described herein contain less chlorine than standard commercial grades of tetrachlorinated (or greater) copper phthalocyanine pigments while achieving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. The inventive pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.
