ABSTRACT:
A process for preparing photographic elements comprising a support, a layer containing an acid dye or acid dye precursor and a layer containing a dye mordant composition, said process comprising coating on a support with a substantially aqueous dispersion of a polymer containing units according to the formula: ##SPC1##
Wherein A represents units of an addition-polymerizable monomer containing at least 2 ethylenically-unsaturated groups; B represents units of a copolymerizable ethylenically unsaturated monomer; Q is N or P; R.sup.1, R.sup.2 and R.sup.3 are independently selected from the group consisting of carbocyclic groups and alkyl groups; M.sup.- is an anion and x is from about 0.25 to about 5 mole percent; y is from about 0 to about 90 mole percent and z is from about 10 to about 99 mole percent; and applying a layer containing acid dyes or acid dye precursors. The polymeric mordants are especially useful in diffusion transfer processes.
