Abstract
1466024 Silver halide photographic material FUJI PHOTO FILM CO Ltd 25 Feb 1975 [25 Feb 1974] 7922/75 Heading G2C A method of preparing a silver halide photographic light-sensitive material comprises (a) adding to a silver halide photographic emulsion wherein at least 60 mole per cent of the silver halide is silver chloride, a water-soluble iridium compound in an amount of 10<SP>-6</SP> to 10<SP>-4</SP> mole of the compound per mole of silver halide, during the first or second ripening of the emulsion, (b) subsequently adding to the emulsion a hydroxytetracizaindene and a polyoxyethylene compound and (c) coating the emulsion in a layer on a support. "Pressure marks" particularly in the case of lithographic photosensitive materials are prevented. Suitable iridium salts and complex salts are listed. Preferably 10<SP>-4</SP> to 10<SP>-2</SP> mole of the hydroxy-tetracizaindene per mole of silver halide is used. Suitable polyoxyethylene compounds include condensation products with an alcohol, glycol, carboxylic acid amine or hexital and also copolymers and block copolymers of ethylene and propylene oxides. The silver grain size is generally 0À04 to 1 micron, preferably 0À1 to 0À7 micron.
