Abstract:
A heat developing color photosensitive material comprising a substrate carrying thereon a photosensitive silver halide, binder, a compound represented by the formula (I) or (D) and a two-equivalent coupler which forms or releases a diffusive cyan, magenta, or yellow dye by reaction with an oxidized product of the compound represented by the formula (I) or (D), further comprising at least one of compounds represented by the formulae (II-a), (IV-a), (IV-b), (IV-c), (IV-d), (IV-e), and (IV-f and (IV-g); wherein Z represents a carbamoyl group, an acyl group, an alkoxycarbonyl group, an aryloxycarbonyl group, a sulfonyl group or a sulfamoyl group, and both Q1 and C represent an atomic group forming an unsaturated ring; wherein, R1 to 1 each independently represent a hydrogen atom or substituent, A represents a hydroxyl group or substituted amino group, X represents a linkage group with a valency of two or more selected from the group consisting of â€”COâ€”, â€”SOâ€”, â€”SO2â€”, and â€”PO1 and R2 and, R3and R4 each independently may bond with each other to form a ring; wherein Ball represent an organic ballasting group which allows the compounds represented by the formula (II-a) to become non-diffusive, when R1 is non-difffusive, Ball may not be required; Y1 represents a carbon atom group required for completing a benzene nucleus or naphthalene nucleus; R1 represents an alkyl group, cycloalkyl group, aralkyl group, aryl group, amino group or heterocyclic group, R2 represents a hydrogen atom, halogen atom, alkyl group, cycloalkyl group, aralkyl group, aryl group, heterocyclic group, alkoxy group, aryloxy group, acyl group, alkyloxycarbonyl group, aryloxycarbonyl group, carbamoyl group, sulfainoyl group, alkylsulfonyl group, arylsulfonyl group, acylamino group, alkylthio group, or arylthio group; n represents an integer from 0 to 5, and when n is 2 to 5, R2 may be the same or different, or a plurality of R2 groups may bond together to form a ring; when Y represents an atomic group required for completing a naphthalene nucleus, Ball and R2 can be bonded to any one of the rings in the naphthalene nucleus; wherein, A represents a bivalent electron attractive group, R21 represents an alkyl group, an aryl group, an alkoxyl group, an aryloxy group, an alkylamino group, an anilino group or a heterocyclic group; 1 represents an integer of 1 or 2; R22 represents an alkyl group, an alkoxy group, a hydroxyl group or a halogen atom, m represents an integer from 0 to 4; Q2 represents a benzene ring or heterocyclic ring which may be condensed with a phenol ring; R23 represents an aryl group, an aryl group or a heterocyclic group; Y2 represents an aryl group, an alkyl group, a heterocyclic group, a â€”P(&boxH;O) (Rb)â€”Ra group, or a â€”C(&boxH;O)-Ra group; Râ€²24 represents an alkylene group, an arylene group or an aralkylene group; R24 represents an alkyl group or an aryl group; wherein, Y2 and R24 cannot represent an alkyl group simultaneously; Ra and Rb each independently represent an alkyl group, an aryl group, an amino group, an alkoxy group, or an aryloxy group; n represents an integer from 1 to 5; R25 represents a hydrogen atom, an alkyl group, an aryl group, a phenylsulfonyl group, or an acyl group; R26 and R24 have the same meaning; R25 and R26 may close a ring to form a 5- to 7-membered ring; R27 and R28 have the same meaning as R24, and may close a ring to form a 5- to 7-membered ring; and R29 represents an alkyl group having 12 to 50 carbon atoms in total; represents a 5- to 7-membered heterocyclic ring; wherein the photosensitive material has at least three silver halide emulsion layers each having light sensitivity in a different spectral range; wherein the coupler is present in an amount of 0.05 to 5.0 mmol/m2; wherein the compound represented by formula (I) or (D) is present in an amount of 1 to 10 times the amount of the coupler; and wherein the compound represented by formula (II-a) is present in an amount of 0.01 to 100 times the amount of the compound represented by formula (I) on a molar amount basis.
