Abstract

1318852 Photographic diffusion transfer EASTMAN KODAK CO 14 Jan 1971 [ 14 Jan 1970] 1831/71 Heading G2C Silver salt diffusion transfer process is carried out in the presence of a 5-selenyl-1,2,3,4- tetrazole as toning agent. The tetrazole is preferably substituted in the 1-position and is added to the receiving material, processing liquid or silver halide emulsion. Preferably the receiving sheet contains a polyvinyl quaternary salt, an iodide an Ag salt or complex, and Pd nuclei and has a release coating.
