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 and a hydrophobic polymer having an acidic group. 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 a 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 10 mol %: ##STR1## in which each of R.sup.1 and R.sup.2 independently is hydrogen, an aliphatic group or an aromatic group.
