Abstract
Abstract AN IMPROVED DEVELOPING SYSTEM FOR DRY OR ESSENTIALLY DRY PHOTOGRAPHIC PROCESSING COMPRISES A PELLICLE CONTAINING PHOTOGRAPHIC DEVELOPER AND A WEB CONTAINING ACTIVATOR FOR THE DEVELOPER. THE SYSTEM MAY ALSO INCLUDE NECLEATING MATERIALS AND COMPLEXING AGENTS FOR POSITIVE PRINT PRODUCTION. THE SYSTEM IS PARTICULARLY SUITABLE FOR SILVER HALIDE MICROFILM PROCESSING AND THE LIKE. IN ONE EMBODIMENT THE PELLICLE IS LAMINATED WITH THE WEB AND THE COMBINATION LAMINATED TO A PHOTOGRAPHIC EMULSION BEARING A LATENT IMAGE TO TRANSFER ACTIVATOR AND DEVELOPER TO THE EMULSION. FOLLOWING DEVELOPMENT AND DELAMINATION, THE PELLICLE REMAINS WITH THE WEB. IN ANOTHER EMBODIMENT, THE PELLICLE IS TEMPORARILY LAMINATED WITH THE WEB TO IMBIDE DEVELOPER INTO THE WEB WHEREUPON THE PELLICLE IS REMOVED AND THE WEB LAMINATED WITH THE PHOTOGRAPHIC EMULSION, AS ABOVE. NUCLEATING AND COMPLEXING AGENTS CAN BE INCLUDED, TO REMAIN WITH THE WEB, TO PROVIDE A POSITIVE PRINT BY DIFFUSION TRANSFER OR TO AID IN STABILIZATION OF THE PHOTOGRAPHIC EMULSION.
