Abstract
A heat-developable color light-sensitive material comprising a support having thereon at least a light-sensitive silver halide emulsion, a hydrophilic binder and a dye-donating compound capable of releasing a diffusible dye in correspondence or counter-correspondence to the silver development, wherein at least two light-insensitive layers are provided between the support and a light-sensitive layer closest to the support and the light-insensitive layer not adjacent to the light-sensitive layer contains at least one compound represented by the following formula (I) or (II): wherein R1 to R6 are defined herein wherein R7, R8 and R9 are defined herein and Y represents —CO— or —SO2—.
Claims6
A heat-developable color light-sensitive material having a multi-layer structure, comprising a support having thereon at least a light-sensitive silver halide emulsion, a hydrophilic binder and a dye-donating compound capable of releasing a diffusible dye in correspondence or counter-correspondence to the silver development, wherein at least two light-insensitive layers are provided between the support and a light-sensitive layer closest to the support and the light-insensitive layer not adjacent to the light-sensitive layer contains at least one compound represented by the following formula (I) or (II):
- wherein R1 to R6 each represents hydrogen atom, a halogen atom, a hydroxyl group, a cyano group, a sulfo group, a carboxyl group, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted sulfonyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted arylcarbonyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted amino group or a substituted or unsubstituted acyloxy group, provided that at least one of R1 and R3 and at least one of R4 and R6 represent a hydroxyl group and that R1 and R2, R2 and R3, R4 and R5, or R5 and R6 may be combined with each other to form a ring, X represents a divalent linking group, and n represents 1 or 0;
- wherein R7 and R8 each represents hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted carbamoyl group, a substituted or unsubstituted sulfamoyl group, a substituted or unsubstituted acyl group, a substituted or unsubstituted arylcarbonyl group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group, a substituted or unsubstituted alkylthio group, a substituted or unsubstituted arylthio group, a substituted or unsubstituted alkoxycarbonyl group, a substituted or unsubstituted aryloxycarbonyl group, a substituted or unsubstituted amino group or a substituted or unsubstituted acyloxy group, provided that R7 and R8 may combine with each other to form a ring, Y represents —CO— or —SO2—, and R9 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted heterocyclic group, a substituted or unsubstituted alkoxy group, a substituted or unsubstituted aryloxy group or a substituted or unsubstituted amino group.
