PROBLEM TO BE SOLVED: To provide an aqueous dispersion containing photosensitive silver salt and a non-photosensitive silver salt of an organic carboxylic acid for a photothermographic material, having improved stability of background density at high temperature and high humidity, and to provide a method for preparing the dispersion and a photothermographic recording material. SOLUTION: The method for separately preparing a second aqueous dispersion, containing photosensitive silver halide and a third aqueous dispersion containing a non-photosensitive silver salt of an organic carboxylic acid and producing a mixture of these, where the mixture does not substantially contain salts of >=12C aliphatic carboxylic acids and a step selected from a step for raising the pH of the second aqueous dispersion to at least 8.0 before mixing with the third aqueous dispersion includes a step for raising the pH of the third aqueous dispersion to at least 8.0 before mixing with the second aqueous dispersion and a step for raising the pH of the mixture to at least 8.0 is included.
