Abstract
A photothermographic material includes on a support a non-photosensitive sliver salt, a photosensitive sliver halide, a nucleation agent, and a binder, and a layer containing specific compounds is formed on an outer side of the image forming layer. Thus, there are obtained such images optimal for photomechanical processes as having a high Dmax (maximum density), a low fog, a good coated surface condition, and less surface defects such as repellency, coating lines or the like.
Claims23
A photothermographic material comprising on a support a non-photosensitive silver salt, a photosensitive silver halide, a nucleation agent, and a binder,
- wherein a layer is formed on or above an image forming layer comprising the photosensitive silver halide, said layer comprising:
- one or more organic acid compounds represented by the following Formula (1),
- where T represents a univalent substituent and k1 represents an integer of from 0 to 4;
- in the case of k1>2, more than one T may be the same or different from one another and may be combined to form a ring;
- L1 and L2 each represents a bivalent linking group;
- n1 and n2 each independently represents an integer of from 0 to 30,
- and one or more compounds represented by the following Formula (2),
- R−(A)n−Y (2)
- where R represents an alkyl group selected from the group consisting of perfluorohexyl, perfluoroheptyl, perfluorooctyl, perfluorononyl, perfluorodecyl, perfluorododecyl, and perfluorohexadecyl;
- A represents a bivalent linking group;
- n represents an integer of from 0 to 50;
- Y represents —SO3M or —OSO3M;
- M represents a hydrogen atom, an alkali metal atom, alkaline-earth metal atom, an ammonium group or a lower alkylamine.
