Abstract

Copper phthalocyanines are commercially important organic pigments for blue shades of colour. They are dispersed by mechanical means as tiny molecular crystals (of dimensions 0.02-0.5 µm) into a wide range of commercial media to form products such as printing inks, paints and coloured plastics. Many important technological properties of copper phthalocyanine pigments, including colour strength and dispersion performance, depend on the physical properties of their crystals, notably crystal lattice type, crystal size and crystal shape. The roles which these crystal properties play in determining a copper phthalocyanine pigment's technological performance are briefly reviewed. The reduction of crystal aggregation during the manufacture of a copper phthalocyanine pigment and the control of flocculation in an application medium are also highlighted.
