Abstract
A heat developable color light-sensitive material containing at least light-sensitive silver halide, a binder, and a dye-providing compound on a support, wherein at least one of the compounds represented by formula (1) is contained as the above dye-providing compound, and the amount of the above binder is 5 g/m.sup.2 or less: ##STR1## wherein veriables in the above formula are defined in the specification. The heat developable color light-sensitive material which provides an excellent discrimination of an image and is less susceptible to an influence by a fluctuation in a development processing condition.
Claims4
An image-forming process comprising heating a heat developable color light-sensitive material at the same time as or after an imagwise exposure, wherein said heat developable color light-sensitive material comprises a support having thereon at least one silver halide emulsion layer and containing a compound represented by formula (4) in said emulsion layer or another hydrophilic colloid layer:
- Y--(G--X'--(L-(Dye).sub.p).sub.m).sub.n ( 4)
- wherein Dye is an image-forming dye or a precursor thereof;
- Y is a group able to differentiate diffusibility of a dye component inversely corresponding with a light-sensitive silver halide having an imagewise latent image, having the following formula:
- ##STR103## wherein EAG is a group receiving an electron from a reductive material;
