PCT No. PCT/EP91/00977 Sec. 371 Date Nov. 9, 1992 Sec. 102(e) Date Nov. 9, 1992 PCT Filed May 24, 1991 PCT Pub. No. WO91/19225 PCT Pub. Date Dec. 12, 1991.A photographic donor material useful in forming continuous tone images in a silver salt diffusion transfer process is comprised of a support; a photosensitive silver halide emulsion layer in which the silver halide is at least 80% silver chloride and is substantially free of iodide; and, located between the photosensitive silver halide emulsion layer and the support, a silver halide emulsion layer which is non-photosensitive under the conditions in which the donor material is used.
