Abstract (en)
A silver salt diffusion transfer method comprising imagewise exposing a light-sensitive material comprising a support having provided thereon at least (a) an image receiving layer containing a silver precipitant, (b) a peeling layer, (c) an antihalation layer having a light blocking function, and (d) a light-sensitive silver halide emulsion layer, overlaying the light-sensitive material with a processing sheet comprising a support having provided thereon a hydrophilic colloid layer containing a solvent for silver halide, developing the material by a silver salt diffusion transfer in the presence of a small amount of water, a developing agent, at least one of a base and a base precursor, and peeling off the peeling layer and the layers over the peeling layer from the image receiving layer to obtain a positive image on the image receiving layer. Furthermore, a film unit using the above-described silver salt diffusion transfer method is described.
