    Abstract: Finely divided, agglomerated crude polyhalo-copper phthalocyanine is recrystallized (conditioned) by heating the crude pigment with benzoic acid, toluic acid, ethylbenzoic acid or a mixture of these, in the presence of water, at from 80.degree. to 130.degree. C.The resulting polyhalo-copper phthalocyanine pigments are readily dispersible and of high color strength, and pigmentary forms ranging from transparent to high-hiding can be obtained in a selective manner.The carboxylic acids used as conditioning media can readily be recovered by acidifying the mother liquor.

  • Patent number: 4606859
    Abstract: An infra-red absorbing phthalocyanine compound in which each of at least five of the peripheral carbon atoms in the 1, 4, 5, 8, 9, 12, 13 or 16 positions (the "3,6-positions") of the phthalocyanine nucleus, as shown in Formula I, is linked by an atom from Group VB or Group VIB of the Periodic Table, other than oxygen, to a carbon atom of an organic radical. In preferred compounds each of the eight 3,6-positions is linked by an atoms from Group VB or Group VIB, especially sulphur, selenium or nitrogen, to an organic radical.
