ABSTRACT:
A photosensitive material for diffusion transfer process is disclosed according to which characteristic such as high maximum density, high contrast and image reproducibility can be stably obtained. This photosensitive material comprises a support and, provided thereon, a silver halide emulsion layer and a hydrophilic colloid layer and which is processed in contact with an image receiving material in a processing solution for silver complex diffusion transfer process wherein at least one of the silver halide emulsion layer and the hydrophillic colloid layer permeable to water contains a hydroxybenzene developing agent; when the layers on the emulsion layer coated side are immersed in a 0.1N aqueous sodium hydroxide solution at 20.degree. C. for 1 minute, amount of solution absorbed in the layers is 3.5-7.0 ml per 1 g of hydrophilic colloid; and the support comprises a paper coated with polyolefin resin on both sides and has a water content of 5.5%-7.5%.
