ABSTRACT:
A method of fabricating a succession of photographic diffussion transfer film units, each including photosensitive and second sheets secured in face-to-face relation; a container of processing composition; and means for collecting and retaining excess processing composition. In the fabrication method a succession of photosensitive elements are adhered in superposed position with a second element to form a sandwich -- such adherence to be accomplished without the employment of external transverse binders or tapes. Other components of the film units, including containers, processing composition trapping elements and associated components are preferably mounted along lateral and/or transverse portions of the structure with subsequent transverse severance of the composite units each from the other to form individual film units.
