Abstract
Abstract A photographic element comprising a support having coated thereon at least one photographic silver halide emulsion and at least one binding agent comprising a film-forming, addition interpolymer comprising A. from about 1 to about 50% by weight of a polymerized monomer containing active methylene groups and having the formula wherein R1 is hydrogen, methyl or and R2 and R3 are independently selected from the group consisting of alkyl radicals, cycloalkyl radicals and aryl radicals; and B. from about 50 to about 99% by weight of at least one additional polymerized ethylenically unsaturated monomer free of active methylene groups.
