PURPOSE:To improve the characteristics of a layer for shielding ultraviolet rays by incorporating an ultraviolet absorber which is leached from a constituent layer of a sensitive material or is bleached in the layer into the backing layer of the sensitive material so as to provide specified absorbance. CONSTITUTION:One side of a support is coated with a silver halide emulsion layer and a protective layer, and the other side is coated with a backing layer and a backing protective layer to form a sensitive material. An ultraviolet absorber is incorporated into a layer other than the emulsion layer and the protective layer therefor, e.g., the underlayer, the backing layer or the protective layer therefor to obtain a photosensitive silver halide material for a daylight room. By incorporating the ultraviolet absorber into a constituent layer of the sensitive material, the material has 0.65-1.7 absorbance to 310-420mmu wavelengths or the luminous intensity of a superhigh voltage mercury lamp, and it can be exposed with a conventional exposer in a daylight room. When the material is developed, the absorber can be inactivated without deteriorating the sensitivity and causing fog. |
