    摘要: The invention provides a diffusion transfer receiver comprising a support with a non-light-sensitive image receiving layer coated onto each face thereof, said image receiving layer in each case comprising a catalytic nuclei layer for physical development of transferred complexed silver halide and each composite comprising a diffusion modifying active component which is preferably a tone controlling compound. The composites of Side 1 and Side 2 are different constitutions so as to provide receivers suitable for different end users. For example Side 1 can be made suitable for creative designers while Side 2 can be made suitable for pre-sensitized plate-makers.The invention also provides a method for improving transmission density of a receiver sheet in a non-light-sensitive image receiving layer of a silver diffusion transfer process which method comprises utilizing in the receiver layer an S-thiuronium alkyl sulfonate transmission density enhancer.

    摘要: A non-light-sensitive image-receiving element useful in a silver complex diffusion transfer process includes at least one layer containing certain tone controlling agents that accelerate the physical development of silver. Compounds useful for this purpose are alkyl disulfides substituted by a water solubilizing group, thiazolidine carboxylic acids, .gamma.-thiobutyrolactones, higher alkyl thioglycolates, and carboxy-substituted rhodanines.

    摘要: A method of forming a photographic image in an imagewise exposed high contrast photographic material free from nucleating agents comprising a support bearing a silver halide emulsion layer comprising silver halide grains wherein at least 10% of the silver halide grains are spectrally sensitized and a hydrophilic colloid having a silver:hydrophilic colloid ratio above 1. The method comprises developing the material in a developer comprising an ascorbic acid developing agent at a pH no greater than 10.5, the developer being free of hydroquinone.
