Addition polymers containing at least 10 mole % of recurring structural units of formula I are useful mordants for acid dyes which preferably contain at least two sulfo groups. The polymers can be used together with the dyes in dyed layers of photographic recording materials, such as in antihalo or filter layers. ##STR1## in which Q represents N or P; R.sup.1, R.sup.2, R.sup.3 represent alkyl or carbocyclic radicals or two of R.sup.1, R.sup.2 and R.sup.3 complete a 5- or 6-membered heterocyclic ring, R.sup.4 represents H or alkyl, X.sup..crclbar. represents an anion.
In a photographic recording element, comprising a layer support, at least one layer comprised of photosensitive silver halide emulsion supported on said layer support, and at least one other supported layer as a dyed layer containing uniformly distributed therein a polymeric mordant for acid dyes and at least one acid dye,
