Abstract

Photographic element and diffusion transfer assemblages are described which contain a novel mordant comprising recurring units having the formula ##STR1## wherein A represents recurring units derived from an .alpha.,.beta.-ethylenically unsaturated monomer; PA1 R represents hydrogen or methyl; PA1 each R.sup.1 independently represents hydrogen or an alkyl group of 1 to about 4 carbon atoms; PA1 Q represents an alkyl, substituted alkyl, cycloalkyl, aryl or substituted aryl group; PA1 X.sup..crclbar. represents an anion; PA1 w is from about 0 to about 25 mole percent; PA1 x is from about 30 to about 90 mole percent; PA1 y is from about 8 to about 65 mole percent; and PA1 z is from about 2 to about 9 mole percent.
