Abstract: A photothermographic material is disclosed, comprising a support having on at least one surface thereof a light-sensitive silver halide grain, an organic salt, a reducing agent for silver ion and a binder, wherein the heat-developable light-sensitive material contains a methine dye represented by formula (I).

Abstract: A photothermographic material comprising light-sensitive silver halide grains, with the photosensitive material further comprising a heptamethine cyanine dye containing at least one arylthio or thienyl group as substituent.

Abstract: A photothermographic material has a photosensitive layer containing a binder, organic silver salt, reducing agent, and silver halide on one surface of a support. The photosensitive layer further contains a specific sulfur-containing compound and a merocyanine dye of specific structure and has an absorbance of 0.15-1.0 at an exposure wavelength. Sharpness, sensitivity, and aging stability are improved.

Abstract: A photothermographic material containing photosensitive silver halide grains, in which a cyanine dye containing at least one of an alkylthio group, an arylthio group, and a substituent group having a thioether bond is included, thereby the photographic material exhibiting low fogging, high sensitivity, and improved stability.

Abstract: A silver halide photographic material which is useful for photography and diagnostic imaging and exhibits excellent storability to ordinary aging, excellent image storability, high sensitivity and low D.sub.min is disclosed. The heat-developable silver halide infrared ray-sensitive material comprises a support having on one side of the support an emulsion layer containing a binder, a nonsensitive silver salt, a reducing agent for silver ion and silver halide grains spectrally sensitized at a wavelength within the region of from 750 to 1,400 nm, wherein the nonsensitive silver salt comprises a mixture of silver salts of at least three kinds of acids, one of the acids is behenic acid, and the content of the behenic acid in the acids is from not less than 35 to less than 90 mol %.

Abstract: A silver halide photographic material comprising a transparent support and at least one silver halide emulsion layer provided on at least one side of said transparent support, said at least one silver halide emulsion layer comprising silver halide grains, wherein at least 50% of the total projected area of said silver halide grains accounts for silver chloride-containing tabular grains having a silver chloride content of 20 mol % or more, and the tabular grains have an average aspect ratio of 2 or more, and the silver halide photographic material contains at least one compound represented by formula [I] or (A): ##STR1## The photographic material can reduce pollution caused by developing solutions and fixing solutions, and reduce the replenishment rate thereof.

Abstract: A silver halide photographic material is disclosed, comprising at least one silver halide emulsion layer on a support and a backing layer on the surface of the support opposite to the emulsion layer, wherein said silver halide emulsion layer comprises tabular grains having an aspect ratio of not less than 3 in a proportion of not less than 50% as calculated in the terms of projected area of the silver halide grains contained in the emulsion layer and the surface on the backing layer side has a Beck smoothness of not more than 150 seconds.
