Color light-sensitive material
摘要:
A heat-developable color light-sensitive material is dis- doaed, 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 non-diffusible form, said compound of formula (A) being represented by
wherein R 1 , R 2 , and R 3 each represents a hydrogen atom, analkyl group, a cycloalkyl group, an aryl group, an aralkyl group. an alkoxy group, an aryloxy group, an acylamino group. and alkylthio group, an arylthio group, or a halogen ntom. provided that at least one of R 1 , R 2 , and R 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.
