ABSTRACT:
Disclosed herein are compositions useful for the preparation of flexible coatings, particularly to photographic materials, which have improved stability to organic solvents and dissolved salts. The compositions comprise an aqueous dispersion of a hydrophilic colloid and a copolymer having a glass transition temperature less than or equal to 60.degree. C. comprising: from about 50 to about 70 percent by weight of an ester of an ethylenically unsaturated carboxylic acid; from about 2 to about 18 percent by weight of an amide of an ethylenically unsaturated carboxylic acid; from about 10 to about 30 percent by weight of a vinyl benzene; and from about 2 to about 18 percent by weight of a sulfonate monomer having the formula ##STR1## wherein R is hydrogen or alkyl; R.sup.1 is selected from the group consisting of alkylene and ##STR2## R.sup.2 is amino substituted with alkyl or hydrogen, or --CH.sub.2).sub.n O-- wherein n is an integer from 0 to 5; m is either 0 or 1; and X is hydrogen or a monovalent cation.
