Abstract
Nanoscale pigment particles of phthalocyanine pigments are prepared by providing a unsubstituted phthalocyanine chromogen material and a substituted phthalocyanine chromogen material, reacting the unsubstituted phthalocyanine chromogen material and the substituted phthalocyanine chromogen material to form a mixture of unsubstituted phthalocyanine dye molecules and substituted phthalocyanine dye molecules, and causing the substituted phthalocyanine dye molecules to non-covalently associate with the unsubstituted phthalocyanine dye molecules, so as to limit an extent of particle growth and aggregation and result in nanoscale pigment particles.
