    • 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%.
    • 公开了用于扩散转印方法的感光材料,其中可以稳定地获得诸如高最大密度,高对比度和图像再现性等特征。 该感光材料包括载体,并且在其上提供卤化银乳剂层和亲水胶体层,并且在银络合物扩散转移方法的处理溶液中与图像接收材料接触地加工,其中至少一种卤化银 乳液层和可透水的亲水胶体层含有羟基苯显影剂; 当乳液层被覆层的层在20℃下浸渍在0.1N氢氧化钠水溶液中1分钟时,每层亲水胶体中吸收的溶液量为3.5-7.0ml; 支撑体包括两面涂布有聚烯烃树脂的纸,其含水量为5.5%〜7.5%。
