摘要： In a photographic monosheet material for the dye diffusion transfer process a temporary bond is adjusted between a first layer and a second layer by placing between said layers another layer of a graft polymer which is obtained by grafting a monomer containing double bonds capable of radical polymerization onto a hydrophilic linear basis polymer. The two layers are firmly bonded to each other but are easily separated, when the processing liquid is forced between them.

摘要： A neutralization system for the dye diffusion transfer process comprises an acid polymer layer containing a polymer with free acid groups and a retarding layer. The retarding layer contains a hydratable polymer which in its non-hydrated state is a barrier for hydroxyl ions and in its hydrated state provides no resistance for diffusing hydroxyl ions. The retarding layer is arranged between a laminate consisting of a light-sensitive film unit comprising at least a light-sensitive silver halide emulsion layer and a non-diffusible dye giving compound associated with the light-sensitive silver halide emulsion layer. The retarding layer allows a first high pH value to be maintained during a first time interval which is sufficient and necessary for producing the desired image density in the image receiving layer and thereafter a second low pH value to be adjusted within a second time interval which is less than half as long as the first. Suitable polymers for the retarding layer are homo-, co- and graftpolymers of 1,2-dimethoxyethylene.
