Abstract

934,199. Photographic colour materials. PERUTZ PHOTOWERKE G.m.b.H. Aug. 21, 1961 [Aug. 20, 1960], No. 30152/61. Class 98 (2). Photographic silver halide colour emulsions comprise either (a) a water-insoluble phenolic coupler which is free from acid groups and contains a straight or branched hydrocarbon chain of 10-21 carbon atoms and which may carry substituents and a sensitizing dye of the general formula wherein Y is S or Se, R is alkyl, A is alkylene and X is an anion and the benzene nuclei may be substituted, or the anhydro form thereof, or (b) a water-insoluble pyrazolone coupler which is free from acid groups and contains a straight or branched hydrocarbon chain of 10-21 carbon atoms and which may carry substituents and a sensitizing dye of the general formula wherein the symbols are as defined above and the benzene nuclei may be substituted, or the anhydro form thereof, the colour couples being incorporated into the emulsions without the aid of an oil-former. Preferably, the couplers are dissolved in a water-immiscible organic solvent having a boiling point below 175‹ C. before adding them to the emulsion, and then subsequently vaporizing off the solvent. Suitable known colour couplers and sensitizing dyes are specified. Specification 541,589 and German Specifications 704,141, 725,872 and 726,611 are referred to.
