ABSTRACT:
This application discloses novel self-developing film units of the integral type. The film units have spacers or rails positioned between the superposed sheets for controlling the thickness of the applied layer of processing fluid. The rupturable pod is attached to the remainder of the film unit at only one edge, so that it may "float" after the processing fluid has been applied. A spacer is bonded to the mask in the area overlying the pod. The mask may be folded over and around only the leading and trailing ends of the film unit.
