Abstract

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.⊕ 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 1 represents a hydrogen atom or a lower alkyl group; R 2 and R 3 , which may be the same or different, each represents an alkyl group or an aralkyl group, or R 2 and R 3 may combine together with the nitrogen atom to which they are attached and form a 5- or 6-membered ring; X.sup.⊖ 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%.
