Heat-developable light-sensitive material and method of forming color images |
(57) 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.
