Abstract
805,827. Photographic light - sensitive materials. ILFORD, Ltd. April 23, 1957 [June 7, 1956], No. 17581/56. Class 98(2) A photographic gelatino silver halide emulsion layer has its sensitivity increased by adding to the layer or to a colloid supercoat layer the condensation product of ethylene oxide with castor oil. It is preferred to include, in one of the layers, an anti-foggant such as a 4-hydroxy-6- alkyl-1:3:3a:7- tetrazaindene. Specification 805,826 is referred to.
