Pigment compositions containing chlorinated copper phthalocyanine pigments in the gamma crystal form

The present technology is directed to pigment compositions having a pure, or substantially pure, γ crystal form, containing less chlorine than standard tetrachlorinated copper phthalocyanine pigments, while giving similar color space, chromaticity, fastness properties, and color travel in automotive...

Zusammenfassung:	The present technology is directed to pigment compositions having a pure, or substantially pure, γ crystal form, containing less chlorine than standard tetrachlorinated copper phthalocyanine pigments, while giving similar color space, chromaticity, fastness properties, and color travel in automotive waterborne and solvent borne systems. These pigments are more advantageous from a toxicity and environmental perspective, and allow the manufacturer to produce pigments in a safe and economical manner.
