ABSTRACT:
A photosensitive material having a widened temperature lattitude. The photosensitive material is described, comprising a support having thereon at least one silver halide emulsion layer associated with a dye-providing compound capable of forming an imagewise mobile dye as the result of exposure and development, wherein a hydroquinone derivative and a water-insoluble but organic solvent-soluble homopolymer or copolymer having a recurring unit containing a ##STR1## bond in the main chain or side chain are integrated and dispersed as individual particles in a hydrophilic colloid of the silver halide emulsion layer or layers or the dye providing compound containing layer or layers.
