ABSTRACT:
Photographic element used in color diffusion transfer processes comprising an image receiving layer containing a polymer having monomer units represented by either Formula I or Formula II ##STR1## wherein A is a copolymerizable monomer unit having at least two ethylenically unsaturated groups; B and B' are copolymerizable .alpha.,.beta.-ethylenically unsaturated monomer units; each R.sub.1 is independently hydrogen or methyl; R.sub.2 and R.sub.3 are independently hydrogen, alkyl, or aryl; R.sub.4, R.sub.5 and R.sub.6 are independently alkyl groups; L.sub.1 and L.sub.2 are independently divalent combining groups; X is a monovalent anion; x, y, z, p, q, r, and s, are each copolymerization mole percentages as follows: 0.5.ltoreq.x.ltoreq.6, 0.ltoreq.y.ltoreq.79.5, 20.ltoreq.z.ltoreq.99.5, 0.ltoreq.p.ltoreq.6, 0.ltoreq.q.ltoreq.80, 10.ltoreq.r.ltoreq.90, and 10.ltoreq.s.ltoreq.90.
