Description

ABSTRACT:
A dye fixing material for fixing a mobile hydrophilic dye formed imagewise to a dye fixing layer is disclosed. The mobile hydrophilic dye image is formed by heating a heat-developable silver halide light-sensitive material in a substantially anhydrous condition after or during imagewise exposure. At least one layer of the dye fixing material contains a polymer having monomeric units of the following formula ##STR1## wherein A represents a vinyl monomer unit having no imidazole or imidazolium group, R.sub.1 and R.sub.3 represent a hydrogen atom, an alkyl group, an alkyl group substituted by a group capable of forming a coordinate bond with a metal, or a salt thereof, R.sub.2 and R.sub.5 represent a hydrogen atom or an alkyl, aralkyl, or aryl group, R.sub.4 represents an alkyl or aralkyl group, X.sup..crclbar. represents an acid radical, x is from 0 to 80 mole %, y is from 10 to 100 mole %, z is from 0 to 50 mole %.
