1. A photographic element comprising a support having coated on one side a radiation sensitive silver halide layer or layers and coated on the other side an antistatic layer comprising:

  • ##STR11## wherein;

    A represents units of an addition polymerizable monomer containing at least two ethylenically unsaturated groups;

    B represents units of a copolymerizable α



    -ethylenically unsaturated monomer;

    Q is N or P;

    R1, r2 and R3 are independently selected from the group consisting of carbocyclic and alkyl groups;

    M is an anion;

    x is from about 0.1 to about 20 mole percent;

    y is from about 0 to about 90 mole percent; and

    z is from about 10 to about 99 mole percent and a polymeric hydrophobic binder wherein the weight ratio of said hydrophobic binder to said antistatic polymer is about 5;

    1 to 2;

    1 and wherein the total coverage of said antistatic polymer and said binder is about 0.25 g/m2 to 20 g/m2.
