Abstract
A heat developable color light-sensitive material provided on a support, which is for use in an image forming process comprising using a dye fixing element provided on a support separate from the support for the light-sensitive material, superposing one on another, heat developing to form a diffusible dye in the light sensitive material, and transferring the diffusible dye to the dye fixing element to form an image, is disclosed. The light sensitive material comprises at least a light-sensitive silver halide and dye-donating compounds, and forms or releases diffusible yellow, magenta and cyan dyes by the heat development, the diffusible cyan dye comprising at least two kinds of cyan dyes, the yellow dye, the magenta dye and the cyan dye showing the maximum absorption intensity in spectral absorption at a wavelength of from 440 nm to 460 nm, from 525 nm to 545 nm, and from 610 nm to 640 nm, respectively, and the absorption intensity of the cyan dye satisfying the following requirements (1) to (3): (1) the wavelength (.lambda.C(10%-)) at which an absorption intensity in the short-wavelength side of the cyan dye reaches 10% of a peak absorption intensity is 525 nm to 545 nm; (2) the wavelength (.lambda.C(10%+)) at which an absorption intensity in the long-wavelength side of the cyan dye reaches 10% of a peak absorption intensity is 690 nm or more; and (3) the difference between .lambda.C(10%+) and .lambda.C(10%-) is 155 nm or more.
