Abstract
1,232,853. Dye developer diffusion transfer processes. EASTMAN KODAK CO. July 25, 1968, [July 28, 1967], No. 35562/68. Heading G2C. A dye developer diffusion transfer process comprising imagewise exposing a material comprising a support and at least two silver halide layers sensitized to different spectral regions and each layer containing a dye developer or being directly above a layer containing a dye developer and processing with an alkaline liquid so that the unoxidized areas of the dye developers transfer by diffusion to a receptor layer; dimethyl sulphoxide or 2, 2
