ABSTRACT:
This invention relates to a color silver halide photographic element comprising gelatin, a support bearing at least one dye image forming unit selected from a dye image forming unit comprising at least one red sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, a dye image forming unit comprising at least one green sensitive silver halide emulsion layer having associated therewith a dye-forming coupler, and a dye image forming unit comprising at least one blue sensitive silver halide emulsion layer having associated therewith a dye-forming coupler; and a polymer represented by Formula 1.wherein:A independently represents a bond or a group linking the polymer chain to the SO3−M+group(s),R1independently represents H or a lower alkyl group of from 1 to 4 carbon atoms,M+independently represents an alkali or alkaline earth metal ion or an ammonium or substituted ammonium ion,Z independently represents at least one ethylenically unsaturated, hydrophilic monomer, anda and b represent the weight percent of the respective monomers where a is between 0 and 95%, b is between 5 and 100%, and n is 1 or 2; andwherein the average molecular weight of the polymer is less than about 300,000 and the total amount of the polymer contained in the silver halide element is greater than 1.0% of the total amount of gelatin contained in the silver halide element. It further relates to a method of processing said element.
