发明名称 SILVER HALIDE PHOTOGRAPHIC MATERIAL
摘要 A silver halide photographic material that has a photographic emulsion layer formed on a support comprising paper base coated with a resin on both sides is disclosed. In this photographic material, a hydrophilic colloidal layer containing a material that has an absorption in the wavelength region in which the photographic emulsion layer has sensitivity is provided between the emulsion layer and the support. The surface of the support on the side where the hydrophilic colloidal layer is to be coated has a center-line-average roughness, Ra, of 0.3 - 1.5 .mu.m, and the thickness of this hydrophilic colloidal layer is at least one half the center-line-average roughness, Ra, of the surface of said support. This photographic material has the advantage of imparting improved sharpness and a high degree of whiteness, as well as high sensitivity.
