Silver halide photographic paper having developer in the emulsion layer and a rough hydrophilic backcoating layer |
| abstract |
Blocking between emulsion layer and backcoating layer and haze of the emulsion surface which often occur when silver halide photographic papers are stored in the form of a roll or a stack can be avoided or reduced by providing a silver halide photographic paper comprising a support coated with a resin on both sides where the surface roughness of the resin layer provided on the side where emulsion layer is not present is within the range of 0.7-2.5 mu in terms of center line average height Ra according to JIS B0601. This effect is conspicuous in reduction of blocking and haze which severely occur in the photographic paper where the developer is contained in the photographic layer. |
