发明名称 Silver halide photosensitive material and image-forming method using heat-responsive-discolorable coloring composition
摘要 A silver halide photosensitive material having a substrate, a heat-responsive-discolorable coloring layer and a photosensitive layer coated thereon and having a silver halide, dye-providing compound and a binder, the heat-responsive-discolorable coloring layer containing a heat-responsive-discolorable coloring composition, which is colored at a temperature lower than its discoloration initiation temperature (T) of 60 to 200° C.; which is substantially discolored at a temperature equal to or higher than T; and which does not recover its color once discolored, even when its temperature is lowered to a temperature lower than T again, and the heat-responsive-discolorable coloring composition containing a polymer having a glass transition temperature of 60 to 200° C.
