Abstract

488,555. Coloured photographic material. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.) Jan. 5, 1937, No. 308. [Class 98 (ii)] Photographic emulsions, particularly silver halide emulsions, supports, protective layers, filter layers and anti-halation layers are coloured with phthalocyanines. Copper phthalocyanine may be used for " blueing " barytes paper. Multi-layer material may contain phthalocyanines in one or more emulsion layers or in the support. The water-soluble sulphonated phthalocyanines may be used for making coloured layers, while insoluble, for example metal-free, phthalocyanines may be incorporated in emulsion layers for colour photography. Reference is made to the use of coloured lakes produced by precipitation of basic triphenylmethane or xanthene dyestuffs with phosphotungstic acid and of pigments of the indigo and indanthrene series.
