Film assemblage for color diffusion transfer film

Abstract

Abstract THE PRESENT INVENTION IS DIRECTED TO A NEW AND IMPROVED FILM ASSEMBLY FOR PRODUCING DIFFUSION TRANSFER PROCESS COLOR REFLECTION PRINTS EMPLOYING A FILM PACK OR MAGAZINE TYPE FILM UNIT. THE FILM ASSEMBLY INCLUDES, IN ESSENCE, A GENERALLY RECTILINEAR CONTAINER SELECTIVELY RETAINING, IN ORDER, AND IN STACKED RELATIONSHIP, A DARK SLIDE AND A PLURALITY OF COLOR DIFFUSION TRANSFER PROCESS FILM UNITS CONSTRUCTED AS DETAILED. THE ASSEMBLY SPECIFICALLY COMPRISES, IN COMBINATION, A GENERALLY RECTILINEAR CONTAINER INCLUDING A FOWARD WALL POSSESSING A LIGHT-TRANSMITTING SECTION, A SIDE WALL POSSESSING A WITHDRAWAL ORIFICE THROUGH WHICH A DARK SLIDE AND INDIVIDUAL DIFFUSION TRANSFER PROCESS COLOR FILM UNITS ARE ADAPTED TO BE SELECTIVELY WITHDRAWN SEQUENTIALLY, AND MEANS FOR BIASING THE DARK SLIDE AND FILM UNITS TOWARD THE LIGHT- TRANSMITTING SECTION; A DARK SLIDE DISPOSED SUBSTANTIALLY COEXTENSIVE THE LIGHT- TRANSMITTING SECTION OF THE CONTAINER''S FORWARD WALL AND INCLUDING A LEADING EDGE AND A TRAILING END SECTION; A PLURALITY OF DIFFUSION TRANSFER PROCESS COLOR FILM UNITS EACH INCLUDING A LEADING END AND A TRAILING END SECTION AND COMPRISING A PHOTOSENSITIVE LAMINATE CONTAINING AS ESSENTIAL LAYERS, IN ORDER, A DIMENSIONALLY STABLE TRANSPARENT SUPPORT LAYER, A LAYER ADAPTED TO RECEIVE A DIFFUSION TRANSFER PROCESS DYE IMAGEFORMING MATERIAL DIFFUSION THERETO, AN OPAQUE LAYER, A PHOTOSENSITIVE SILVER HALIDE LAYER HAVING ASSOCIATED A DIFFUSION TRANSFER PROCESS DYE IMAGE-FORMING MATERIAL, A TRANSPARENT DIMENSIONALLY STABLE SHEET SUPERPOSED SUBSTANTIALLY COEXTENSIVE THE SURFACE OF THE LAMINATE OPPOSITE THE TRANSPARENT SUPPORT, AND A RUPTURABLE CONTAINER RETAINING A PROCESSING COMPOSITION INCLUDING AN OPACIFYING AGENT EXTENDING TRANSVERSE THE LEADING EDGE OF THE FILM UNIT TO EFFECT UNDIRECTIONAL DISCHARGE OF THE CONTAINER''S CONTENTS BETWEEN THE TRANSPARENT SHEET AND THE LAMINATE, EACH OF THE FILM UNITS DISPOSED IN STACKED RELATIONSHIP WITHIN THE CONTAINER WITH ITS TRANSPARENT SHEET DISPOSED TOWARD THE LIGHT- TRANSMITTING SECTION AND THE RUPTURABLE CONTAINER TOWARD THE WITHDRAWAL ORIFICE; AND A PLURALITY OF LEADER SHEETS EACH COMPRISING A LEADING AND A TRAILING END SECTION AND INCLUDING A FIRST LEADER SHEET, THE LEADING END SECTION OF WHICH EXTENDS THROUGH THE WITHDRAWAL ORIFICE AND THE TRAILING END SECTION OF WHICH IS SECURED TO THE DARK SLIDE REARWARD OF ITS LEADING EDGE, A SECOND LEADER SHEET INTERCONNECTING THE DARK SLIDE AND NEXT SUCCEEDING FILM UNIT WITH THE TRAILING END SECTION OF THE LEADER SHEET SECURED TO THE LEADING END SECTION OF THE FILM UNIT, AND THIRD LEADER SHEETS EACH INTERCONNECTING A PRECEEDING FILM UNIT AND NEXT SUCCEEDING FILM UNIT IN THE STACK WITH ITS TRAILING END SECTION SECURED TO THE LEADING END SECTION OF THE NEXT SUCCEEDING FILM UNIT.
