Transparency film assemblage with processing liquid pad in envelope

摘要

A transparency film assemblage for use with a camera includes a mount with an aperture therethrough. A film frame have a photosensitive layer is bonded to the mount in a position to cover the aperture. Secured to the mount is a foil sheet folded upon itself to form a moisture impermeable envelope. Within said envelope is a foraminous pad impregnated with developing liquid. Following exposure of the film frame the envelope is opened, the pad is laminated to the photosensitive layer of the film frame and the foil sheet is refolded to encompass the mount, pad and film frame in a light impermeable envelope suitable to be ejected from the camera while film developing continues.
