ABSTRACT:
A process is provided for preparing improved aqueous gelatin compositions for improved coatings, particularly light sensitive photographic coatings, wherein a viscosity increasing amount of a copolymer of an alkali metal or ammonium salt of a sulfonic acid containing polymer with an unsaturated monomer, particularly a copolymer of acrylamide and sodium-2-acrylamido-2-methylpropanesulfonate, is added to an aqueous gelatin composition at a point immediately before any point which requires a high viscosity after and a low viscosity before the addition.
