Abstract
High contrast graphic arts photographic materials exhibiting improved accuracy in image reproduction are comprised of a support, a silver halide emulsion layer having a chloride content of at least 50 mole percent, and a non-electroconductive hydrophilic colloid layer containing both a vinyl polymer and a hydrophilic colloid interposed between the support and the silver halide emulsion layer. A hydrazine nucleating agent is incorporated in or adjacent to the silver halide emulsion layer and the photographic material preferably also contains an amino compound which functions as a booster.
