Abstract
A silver salt photothermographic dry imaging material including non-photosensitive aliphatic carboxylic acid silver salts; a photosensitive emulsion containing photosensitive silver halide grains; a silver ion reducing agent; a binder; and a cyan coloring leuco dye. A percentage of the photosensitive silver halide grains having a mean particle size of 0.01 or more μm and 0.04 μm or less is 5% or more by mass and 50% or less by mass of total photosensitive silver halide grains by conversion into a silver amount.
Claims5
A silver salt photothermographic dry imaging material comprising:
- non-photosensitive aliphatic carboxylic acid silver salts;
- a photosensitive emulsion containing photosensitive silver halide grains;
- a silver ion reducing agent;
- a binder;
- and
- a cyan coloring leuco dye,
- wherein the non-photosensitive aliphatic carboxylic acid silver salts are manufactured by making a silver ion-containing solution using water or a mixture of water and an organic solvent as a solvent react with an alkali metal salt of aliphatic carboxylic acid-containing solution using water, an organic solvent or a mixture of water and the organic solvent as a solvent under existence of tertiary alcohol.
