Abstract:
A thermally developable photosensitive material comprising a support having thereon an organic silver salt, a binder, a photosensitive silver halide, and an infrared-sensitizing dye represented by the following formulas (1), (2), (3) or (4) and a macrocyclic compound containing a heteroatom selected from the group consisting of a nitrogen atom, oxygen atom, sulfur atom and selenium atom:Formula (1) ##STR26##Formula (2) ##STR27##wherein Y.sub.1, Y.sub.2 and Y.sub.11 each are independently an oxygen atom, sulfur atom, selenium atom or --CH.dbd.CH--; L.sub.1 to L.sub.9 and L.sub.11 to L.sub.15 each are independently a methine, group; R.sub.1, R.sub.2, R.sub.11 and R.sub.12 each are independently an aliphatic group; R.sub.3, R.sub.4, R.sub.13 and R.sub.14 each are independently an, alkenyl group, a cycloalkyl group or a heterocyclic group; W.sub.1, W.sub.2, W.sub.3, W.sub.4, W.sub.11, W.sub.12, W.sub.13 and W.sub.14 each are independently a hydrogen atom, a substituent selected from the group consisting of an alkyl group, aryl group, heterocyclic group, halogen atom, vinyl group, trifluoromethyl, alkoxy group, aryloxy group, sulfonyl group, alkoxycarbonyl group, amino group, acyl group, urcido group, thiourcido group, alkylthio group, alkenylthio group, arylthio group, hydroxy and styryl, or a non-metallic atom group necessary to form a condensed ring by bonding between W.sub.1 and W.sub.2, W.sub.3 and W.sub.4, W.sub.11 and W.sub.12, or W.sub.13 and W.sub.14 ; X.sub.1 and X.sub.11 each are an ion necessary to compensate for an intramolecular charge; k1 and k11 each are a number of the ion necessary to compensate for the intramolecular charge; ml is 0 or 1; and n1, n11 and n12 each are 0, 1 or 2, provided that n11 and n12 are not 0 at the same time;Formula (3) ##STR28##Formula (4) ##STR29##wherein Y.sub.21, Y.sub.22 and Y.sub.31 each are independently an oxygen atom, a sulfur atom, a selenium atom, --C(Ra) (Rb)-- group or --CH.dbd.CH-- group, in which Ra and Rb each are an alkyl group, a cycloalkyl group, an aralkyl group, an alkoxyl group, an aryl group and a halogen atom; R.sub.23, R.sub.22, R.sub.31 and, R.sub.32 each are independently an aliphatic group; Rc and Rd each are independently an alkyl group, a cycloalkyl group; an aralkyl group, an aryl group or a heterocyclic group; W.sub.21, W.sub.22, W.sub.23, W.sub.24, W.sub.31, W.sub.32, W.sub.33 and W.sub.34 each are independently a hydrogen atom, a substituent selected from the group consisting of an alkyl group, aryl group, heterocyclic group, halogen atom, vinyl group, trifluoromethyl, alkoxy group, aryloxy group, sulfonyl group, alkoxycarbonyl group, amino group, acyl group, ureido group, thioureido group, alkylthio group, alkenylthio group, arylthio group, hydroxy and styryl, or a non-metallic atom group necessary to form a condensed ring by bonding between W.sub.21 and W.sub.22, W.sub.23 and W.sub.24, W.sub.31 and W.sub.32, or W.sub.33 and W.sub.34 ; V.sub.21 to V.sub.29, sand V.sub.31 to V.sub.33 each are independently a hydrogen atom, a halogen atom, an amino group, an alkylthio group, an arylthio, group, an alkyl group, an alkoxyl group, an aryl group, an aryloxyl group, a heterocyclic group or a non-metallic atom group necessary to form a 5-to 7-membered ring by bonding between V.sub.21 and V.sub.23, V.sub.22 and V.sub.24, V.sub.23 and V.sub.25, V.sub.24 and V.sub.26, V.sub.25, and V.sub.27, V.sub.26 and V.sub.28, V.sub.27 and V.sub.29, or V.sub.31 and V.sub.33 ; X.sub.21 and X.sub.31 each are an ion necessary to compensate for an intramolecular charge; 121 and 131 each an ion necessary to compensate for an intramolecular charge; k21 and k22 each are 0 or 1; n21, n22, n31 and n32 each are 0, 1 or 2, provided that n21 and n22, or n31 and n32 are not 0 at the same time.
