Abstract:
A heat developable light-sensitive material comprising a support, a light-sensitive layer and a non-light-sensitive layer, said light-sensitive layer containing silver halide and a reducing agent, and said non-light-sensitive layer containing a cyanine dye represented by the formula (I-1) or a salt thereof and a base precursor, wherein the cyanine dye or the salt thereof is in the form of solid particles, which are dispersed in the non-light-sensitive layer: ##STR28##in which R.sup.1 is hydrogen, an aliphatic group, an aromatic group, --NR.sup.21 R.sup.24, --OR.sup.21 or --SR.sup.21, each of R.sup.21 and R.sup.24 independently is hydrogen, an aliphatic group or an aromatic group, or R.sup.21 and R.sup.24 are combined to form a nitrogen-containing heterocyclic ring; R.sup.2 is hydrogen, an aliphatic group or an aromatic group; R.sup.3 is an aliphatic group; L.sup.1 is a trimethine or a pentamethine; and each of Z.sup.1 and Z.sup.2 independently is an atomic group forming a five-membered or six-membered nitrogen-containing heterocyclic ring, which may be condensed with an aromatic ring.
