Abstract
The present invention provides a heat-developable light-sensitive material having a support and a light-sensitive layer provided on the support. The heat-developable light-sensitive material contains dyes which are decolorized through reaction with a decolorizing agent during a development process. The dyes are non-diffusible and at least a part of decolorized dyes resulting from the development process is non-diffusible. Also provided is an image forming method using the heat-developable light-sensitive material. The present method provides images having excellent sharpness within a short period of time.
Claims15
A heat-developable light-sensitive material comprising a support and having thereon a light-sensitive layer comprising silver halide grains and a binder wherein the heat-developable light-sensitive material further contains a decolorizable dye layer formed from a dispersion in which oil droplets formed by dissolving the dye in oil and/or oil soluble-polymer arc dispersed into a hydrophilic binder, wherein the dye is decolorized by the reaction with a decolorizing agent or a precursor thereof that is incorporated into the light-sensitive material in advance or incorporated into the light-sensitive material from a processing material in a heat development processing stage, and wherein the dye is non-diffusible and at least a part of the decolorized dye resulting from the heat development process is non-diffusible.
