Abstract
A polymer composition comprising: (a) from 1 to 60 weight percent of recurring units derived from a polymerized vinyl monomer having a primary amine addition salt component or an aminostyrene addition salt component; (b) from 0 to 50 weight percent of recurring units derived from a nonionic polymerized hydrophilic vinyl monomer; and from 20 to 98 weight percent of recurring units derived from a polymerized hydrophobic nonionic vinyl monomer is disclosed for use in coating compositions for polyester supports.
Claims6
A photographic element comprising a silver halide emulsion layer and a discharge-treated polyester film support having coated directly thereon a crosslinked layer of an aqueous polymer and gelatin coating composition wherein the polymer to gelatin ratio is in the range of 95:5 to 60:40 and the polymer comprises
- (a) from 1 to 60 weight percent of recurring units derived from a polymerized vinyl monomer having a primary amine addition salt component or aminostyrene addition salt component;
- (b) from 0 to 50 weight percent of recurring units derived from a polymerized hydrophilic vinyl monomer;
- and
- (c) from 20 to 98 weight percent of recurring units derived from a polymerized hydrophobic nonionic vinyl monomer.
