Abstract

Abstract 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 non-diffusible form, said compound of formula (A) being represented by ##STR1## wherein R 1 , R 2 , and R 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 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.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 292 words
A color light-sensitive material comprising a support having thereon at least one light-sensitive silver halide-containing layer, a binder, a compound 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 ##STR20## wherein R 1 , R 2 and R 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 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 of a group capable of forming a hydroxyl group upon heating and/or by the action of a base, wherein the compound or precursor thereof which reacts with an oxidized compound formed from the compound of formula (A) is selected from the following compounds represented by formula (II): ##STR21## wherein R 1 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic ring; R 2 represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted acyloxy group, or a substituted or unsubstituted sulfonyl group; R 3 represents a hydrogen atom or a group which can be hydrolyzed; and R 5 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic ring.
Claim 2
Dependent Claim 292 words
A color light-sensitive material comprising a support having thereon at least one light-sensitive silver halide-containing layer, a binder, a compound 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 ##STR20## wherein R 1 , R 2 and R 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 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 of a group capable of forming a hydroxyl group upon heating and/or by the action of a base, wherein the compound or precursor thereof which reacts with an oxidized compound formed from the compound of formula (A) is selected from the following compounds represented by formula (II): ##STR21## wherein R 1 represents a hydrogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic ring; R 2 represents a hydrogen atom, a halogen atom, a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, a substituted or unsubstituted acyloxy group, or a substituted or unsubstituted sulfonyl group; R 3 represents a hydrogen atom or a group which can be hydrolyzed; and R 5 represents a substituted or unsubstituted alkyl group, a substituted or unsubstituted aryl group, or a substituted or unsubstituted heterocyclic ring.
Claim 3
Dependent Claim 131 words
A color light-sensitive material as in claim 1, wherein R 1 , R 2 and R 3 each represents a hydrogen atom, an alkyl group having up to 4 carbon atoms, an alkoxy group having up to 4 carbon atoms, or an alkylthio group having up to 4 carbon atoms; X represents a chemical bond or a linking group selected from an alkylene group, ##STR22## dye represents an image-forming dye moiety selected from an azo dye, an azomethine dye, an anthraquinone dye, a naphthoquinone dye, a styryl dye, a nitro dye, a quinoline dye, a carbonyl dye, a phthalocyanine dye, and a xanthene dye; and G is a hydroxyl group or a precursor thereof selected from trialkylsilyl ethers, carboxylic esters, carbonic esters, sulfonic esters, and phosphoric esters of a hydroxyl group.
