摘要:
A heat-developable color light-sensitive material is disclosed, comprising a support having thereon at least one layer containing a light-sensitive silver halide, a binder, a compound containing a color moiety represented by formula (A), and a compound or a precursor thereof which reacts with an oxidized compound formed from the compound of formula (A), thereby converting the oxidized compound into a nondiffusible form, said compound of formula (A) being represented by ##STR1## wherein R.sub.1, R.sub.2, and R.sub.3 each represents a hydrogen atom, an alkyl group, a cycloalkyl group, an aryl group, an aralkyl group, an alkoxy group, an aryloxy group, an acylamino group, an alkylthio group, an arylthio group, or a halogen atom, provided that at least one of R.sub.1, R.sub.2, and R.sub.3 represents a hydrogen atom; X represents a chemical bond or a divalent linking group; Dye represents an image-forming dye moiety; and G represents a hydroxyl group or a group capable of forming a hydroxyl group upon heating and/or by the action of a base.The material provides an image having a low minimum density in highlight areas, and excellent color separation and image preservability.
