Abstract: PROBLEM TO BE SOLVED: To simply prepare the subject polymorph, having a desired particle size and a desired particle size distribution and useful as a pigment for coloring coating materials, etc., by reductively cyclizing phthalonitrile in the presence of an aliphatic alcohol, a redox catalyst, an inorganic base and a specific phthalocyanine derivative. SOLUTION: Phthalonitrile is reductively cyclized in the presence of an aliphatic alcohol, a redox catalyst, an inorganic base and a phthalocyanine derivative (phthalocyanine-sulfonic acid, phthalocyanine-carboxylic acid, an aminomethylated phthalocyanine, a halogenated phthalocyanine, etc.). Thereby, the subject phthalocyanine directly usable as a pigment for coloring printing inks, coating materials and plastics is obtained without passing the phthalonitrile through finishing steps (grinding and/or solvent treatment).

Abstract: A new modification of non-metallised phthalocyanine (IA) has substantial lines in the x-ray powder diagram (CuKa) at 2&thetas; angles of 5.0, 8.3, 9.6, 13.0, 14.4, 16.8, 21.5, 24.2 and 26.8 degrees . Also claimed is a method for directed synthesis of non-metallised phthalocyanine (I) by reductive cyclisation of ortho-phthalodinitrile (o-PDN) in the presence of an aliphatic alcohol, redox catalyst and inorganic base, in which cyclisation is carried out in the presence of specified phthalocyanine derivative(s) (II) to regulate the modification formed.
