PURPOSE:To obtain a photographic light sensitive plate capable of forming a photographic image good in sharpness easily at low cost, by forming a photosensitive emulsion layer on a base and joining a colored filter having an effective max. transmittance in a specified wavelength region onto this layer. CONSTITUTION:A photosensitive emulsion consisting mainly of gelatin, silver bromide grains, etc. is coated on a base 1 of glass, org. film, or the like to form a photosensitive emulsion layer 2. On this layer, a colored filter 3 having an effective max. transmittance in 400-600nm wavelength region is joined to form an intended photographic plate. It also executes the function of a protective film for preventing defects of the emulsion in contact exposure and further during operations such as from negative to positive or from positive to negative processing, or from positive to positive reversal processing. |
