ABSTRACT:
A silver halide photographic light-sensitive material for photomechanical process and a method for the reduction treatment of said light-sensitive material are described. The light-sensitive material comprises a support, at least one light-sensitive silver halide emulsion layer, and at least one light-insensitive upper layer, characterized in that at least one light-insensitive upper layer contains a polymer comprising: (a) a monomer unit containing at least one group having an electric charge; and (b) a monomer unit having a functional group capable of crosslinking through a gelatin hardening agent with a like functional group of another polymer chain of the same type or with gelatin. The light-sensitive material is very advantageous; for example, it has greatly improved reduction treatment suitability, and the reduction treatment suitability is not deteriorated even if the amount of silver coated per unit area is reduced.
