ABSTRACT:
A polyester photographic film support having a surface coated with a subbing layer which comprises a mixture of gelatin and a polymer where the gelatin to polymer ratio is less than 97:3 and such that the combination of dry coverage and weight fraction of gelatin in the mixture satisfies the equation: C+1.32.times.Z.gtoreq.0.825, where C is dry coverage in g/m.sup.2 and Z is the weight fraction of gelatin, and the polymer comprises:
a) from 1 to 60 weight percent of recurring units derived from a 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 hydrophilic vinyl monomer; and
c) from 20 to 98 weight percent of recurring units derived from a hydrophobic nonionic vinyl monomer.
