    摘要: Provided are methods for preparing a phthalocyanine pigment in high yield that eliminate the need to add a heavy metal catalyst. The resulting pigmentary phthalocyanine products thus contain no or only trace amounts of heavy metal impurities. The provided methods produce phthalocyanine pigments that can be used in any application that utilizes phthalocyanine pigments, such as in dispersions, printing inks, paints, plastics and coatings.
