PURPOSE:To reduce the concn. of reaction and to provide uniform etching bleaching effect by affording continuous foam-shaped unevenness to a surface forming a coarse surface. CONSTITUTION:An image receiving material for diffusion transfer of silver complex salt causing small reduction of reaction concn. and etching bleaching effect with a coarse surface is obtd. in a resin coated photographic paper having rough coated surface by coating an image receiving layer contg. physical development nuclei on a base body forming foam-shaped unevenness on the coarse surface. Further, the photographic resin coated paper is formed by using base paper made of pulp usually consisting essentially of natural pulp with roughened surface using a copper plated surface or iron core roll surface roughened by forming fine unevenness by sand-blasting or liquid honing, etc. Useful hydrophilic colloid is a proteinous substance such as gelatin, similar substance, etc. Sulfides or selenides of Au, Ag, Co, Pb, or Cu, or particles of noble metal is used for the physical development nuclei. |
