ABSTRACT:
A photographic light-sensitive material comprising at least one layer containing a polymer dispersion of the following formula (I) or (II) as a mordant ##STR1## wherein A represents a monomer unit obtained from at least one monomer having at least two copolymerizable ethylenically unsaturated groups at least one of which is in the side chain; B represents a monomer unit obtained from at least one copolymerizable monoethylenically unsaturated monomer; D.sup..sym. represents a 5- or 6-membered heterocyclic group containing one or two nitrogen atoms one of which is positively charged and D may contain one or more substituents; R.sub.1 represents a hydrogen atom or a lower alkyl group; R.sub.2 and R.sub.3, which may be the same or different, each represents an alkyl group or an aralkyl group, or R.sub.2 and R.sub.3 may combine together with the nitrogen atom to which they are attached and form a 5- or 6-membered ring; X.sup..crclbar. represents an anion; Q represents an alkylene group, a phenylene group, an aralkylene group or a group of the formula ##STR2## wherein Y represents an alkylene group or an aralkylene group and R represents an alkyl group; and x, y and z represent the molar percentage of the respective units in the polymer and x is about 0.5 to 10%, y is about 0 to 60% and z is about 30 to 99.5%.
