PURPOSE:To thin the photographic constituting layer without rising fog by incorporating a mordant agent in the binder contd. in a nonphotosensitive layer, and a specified yellow filter dyestuff in the nonphotosensitive layer, respectively. CONSTITUTION:In the titled material, the mordant agent is incorporated in the binder contd. in the nonphotosensitive layer, and the nonphotosensitive layer contains the yellow filter dyestuff which can decolor by processing. Namely, as the nonphotosensitive layer which fulfills the function of a yellow filter layer contains the mordant agent and the yellow filter dyestuff, the fog in the emulsion layer does not rise differing from the case of using a colloidal silver, whereby the nonphotosensitive layer is not necessary to separate from the emulsion layer by an intermediate layer. Thus, as the intermediate layer is needless, the photographic constituting layer can reduce the thickness by that of the intermediate layer, thereby improving the sharpness of the titled material. |
