Abstract

As mordant for mordanting diffusing anionic dyes in image receiving layers of photographic dye diffusion materials the invention makes use of addition polymers having at least 10 mole % of recurring structural units of formula I ##STR1## in which Q represents nitrogen or phosphorus; PA1 R.sup.1, R.sup.2, R.sup.3 each represents a carbocyclic or alkyl group or two of these substituents complete a 5- or 6-membered heterocyclic ring PA1 R.sup.4 represents hydrogen or alkyl, PA1 X.crclbar. is an anion.
