Abstract:
A self-developing, photosensitive film unit including a multilayer photosensitive element and a transparent imagerecording element laminated to one another during manufacture and a rupturable container of processing liquid attached to the elements at one end for dispensing its liquid contents between the elements, and adapted to be processed by passing the film unit including the container and laminated elements between a pair of pressure-applying members. The film unit is formed by embossing, or attaching spacer strips, to the lateral margins of an elongated strip and then laminating the strip to a second strip by spreading a film-forming agent between the strips, severing the laminated strips to the required length to form sandwiches each comprising laminated photosensitive and imagerecording elements, securing a binding around at least two sides of each sandwich and attaching a container of processing liquid to one end of the sandwich.
Abstract:
A photographic film unit comprising all of the materials required to produce a photographic print including a pair of sheets secured at their margins in face-to-face relation and a liquid processing agent; and a method of rapidly spreading a viscous liquid processing agent in a continuous uniform layer between the superposed sheets. A film unit is disclosed comprising a photosensitive sheet and a second sheet secured in face-to-face relation at the edges of the sheets by essentially fluidtight binding means adopted to release gas from between the sheets during spreading of the liquid carried in a collapsible container secured at one edge of the sheets so as to discharge its contents between the sheets when compressive pressure is applied to the container. A method is disclosed in which gas is discharged from between the sheets during spreading of the processing liquid therebetween and liquid is prevented from escaping by way of the means for releasing the gas.
