ABSTRACT:
A silver halide light-sensitive material comprises a support, a hardening layer and a light-sensitive layer. The hardening layer contains an ethylenically unsaturated polymerizable compound or an ethylenically unsaturated cross-linkable polymer. The light-sensitive layer contains silver halide and a hydrophilic polymer. The hardening layer or the light-sensitive layer contains a reducing agent. An adhesive layer or the light-sensitive layer contains a water-soluble synthetic polymer. The adhesive layer is provided between the hardening layer and the light-sensitive layer. The water-soluble synthetic polymer comprises a repeating unit represented by the formula (I) in an amount of at least 50 mol %: ##STR1## in which each of n1 and n2 is an integer of 10 to 5,000; each of R.sup.1 and R.sup.2 is hydrogen, an alkyl group or an aryl group; X is --O--R.sup.4 --O-- or --NR.sup.5 --; R.sup.4 is an alkylene group, an alkyleneoxyalkylene group, an arylene group or an aralkylene group; R.sup.5 is an alkyl group or an aryl group; Y.sup.1 is --CO-- or --CONH--; Y.sup.2 is --CO-- or --NHCO--; and R.sup.3 is an alkylene group, an alkenylene group, an arylene group or an aralkylene group.
