ABSTRACT:
Dye diffusion images can be produced by a rapid process in which a first sheet material which contains at least one light sensitive silver halide emulsion on a layer support and at least one color producing compound capable of releasing a diffusible dye on development and/or a second, light insensitive sheet material containing a layer of binder in which is incorporated a salt of a weakly acidic organic compound and a strong organic base is or are moistened with an aqueous liquid and the two sheet materials are then heated to 40.degree.-120.degree. C. with their coated surfaces in contact and subsequently separated.
