Abstract

1398055 Photographic emulsions MITSUBISHI PAPER MILLS Ltd 25 Jan 1973 3924/73 Heading G2C [Also in Division C3] Photographic silver halide emulsions contain a water-soluble resin which is an addition copolymer derived from ethylenically unsaturated monomers and having side-chains comprising carboxylic acid groups, optionally substituted imidazole groups and N-(1,1-dimethyl-3-oxobutyl) aminocarbonyl groups and optionally acid amide groups. Specified copolymers are derived from (1) acrylamide, 1-vinyl-2-hydroxyethylimidazole, acrylic acid and diacetoneacrylamide and (2) acrylamide, diacetoneacrylamide and 1-vinyl-2- methyl-imidazole, copolymer (2) being hydrolyzed to introduce carboxylic acid groups.
