Abstract
1,062,116. Photographic silver halide emulsions. ILFORD Ltd. April 6, 1965 [April 10, 1964], No. 14925/64. Heading G2C. A photographic gelatino silver halide emulsion of improved contrast is made by forming an emulsion in which a predominant proportion of the silver halide grains have a polyhedral shape, i. e. have a number of sides exceeding-eight, and are in the size range 0À5-2 microns and adding at the digestion stage or later a watersoluble mono or disaccharide and also, at a stage not later than the digestion stage, from 1 to 500g. per gram mole of silver of a polyvinyl alcohol having a molecular weight of 10000 to 30000 and containing at least 25% residual acetate. Saccharides mentioned are sucrose, glucose and fructose.
