Abstract

1527435 Silver halide emulsion KONISHIROKU PHOTO INDUSTRY CO Ltd 17 March 1976 [17 March 1975] 10747/76 Heading G2C A silver halide photographic emulsion (having improved sensitivity to flash exposure) comprises 10<SP>-8</SP> to 10<SP>-5</SP> mole of a water-soluble iridium compound per mole of silver halide and a selenium sensitizer. By "flash exposure" is meant exposure for less then 1/10000 sec. generally 10<SP>-5</SP> to 10<SP>-7</SP> secs. to high illuminance sources e.g. lasers, xenon lamps, high pressure mercury lamps. Suitable iridium compounds are IrCl 3 , IrCl 4 , potassium or ammonium hexachloroindate. Selenium compounds specified are potassium selenocyanide, selenious acid, selenium dioxide, colloidal selenium, allyl isoselenocyanate, selenoacetamide, selenoacetone, selenoacetophenone, selenopropionic acid, ethyl selenopropionate, triphenylphosphine selenide, selenourea, methylselenourea, N, N-dimethylselenourea, diethylselenourea and N, N-dimethyl -N'-carboxyethyl - selenourea, and the stable and unstable selenium compounds disclosed in Specifications 1115038, 1098466 and 1201396.
