Abstract

434,474. Photographic emulsions. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Nov. 29, 1933, No. 33468. Void [Abridged as open to inspection under Sect. 91 of the Acts, May 30, 1934]. [Class 98 (ii)] Relates to the manufacture of silver halide emulsions, and consists in substituting for part of the binding agent, e.g. gelatin or collodion, a reduced quantity of a polymeric carboxylic acid or a salt thereof, or of a mixed polymerization product of two or more unsaturated carboxylic acids or derivatives thereof. Examples are given of silver halidegelatin emulsions in which the polymerization product consists of (a) polyacrylic acid, (b) poly(styrol - maleic acid anhydride), and (c) poly (acrylic acid nitrile-acrylic acid).
