Abstract
A silver salt photothermographic imaging material is disclosed, comprising a light-sensitive aliphatic acid silver salt, a light-sensitive emulsion containing light-sensitive halide grains, a reducing agent for silver ions, a binder and a cross-linking agent, wherein the cross-linking agent is an aromatic polyisocyanate compound and the photothermographic material further comprises a compound selected from compounds represented by the following formulas.
Claims10
A photothermographic material comprising a light-insensitive aliphatic acid silver salt, a light-sensitive emulsion containing light-sensitive silver halide grains, a reducing agent for silver ions, a binder and a cross-linking agent, wherein the cross-linking agent is an aromatic polyisocyanate compound and the photothermographic material further comprises a compound selected from the compounds represented by the following formulas (1) through (3)
- wherein R11, R12 and R13 are each a hydrogen atom or a univalent substituent;
- X11 is an electron-donating heterocyclic group, a cycloalkyloxy group, a cycloalkylthio group, a cycloalkylamino group or cycloalkenyl group;
- wherein R21 is an alkyl group;
- R22 and R23 are each a hydrogen atom or a univalent substituent;
- X21 is an ejection-withdrawing group;
- L21 is an aromatic carbon-ring group;
- and n2 is 0 or 1;
- wherein X31 is an electron-withdrawing heterocyclic group, a halogen atom or a haloalkyl group;
- one of R31 and R32 is a hydrogen atom and the other one is a hydroxy group.
