SELF-PROCESSING FILM UNIT HAVING AN INTERNAL DARK SLIDE

摘要

A self-processing photographic film unit of the preregistered integral type includes an internal dark slide which protects the unit from exposure prior to use. The film unit includes a photosensitive element (18) and a cover sheet (30) between which the dark slide (12, 112 or 212) is removably positioned to shield one side of the photosensitive element (18) from light. Exposure from the other side (28) is prevented by an opaque layer (22) in the element (18) itself. When used with an opaque processing composition, the unit can be handled in daylight, without fogging, both before and after exposure. The film unit is adapted for use in commercially available adaptors for professional type cameras. Figure 6 is the preferred figure for the abstract.
