Abstract: Diffusion transfer photographic products and processes are disclosed for forming transparencies wherein a positive silver transfer image is maintained together with a negative silver image in a separate layer, said images being viewed together as a positive transparency. The invention is particularly applicable to forming additive color transfer images. The sum of the projected areas of the silver halide grains in the silver halide emulsion layer does not exceed about 50% of the surface area of the silver halide emulsion layer. Development of the exposed silver halide grains results in little, if any, increase in the projected area whereby the maximum negative silver density is kept low. Predominantly homogeneous grain size silver halide emulsions, preferably of particular mean diameter and grain size distribution, are utilized to obtain good sensitometry in addition to desired minimum and maximum image densities.

Abstract: Projector apparatus employing a cassette-latching shaft member which automatically locates and locks a photographic cassette in an operative location responsive to insertion of the cassette in a cassette-receiving element of the apparatus. Displacement of the shaft member to its cassette-locking position allows engagement of other cooperating elements of the apparatus with the cassette and initiates operation of the latter through a preprogrammed sequence for projection including transport of the film in a forward and rewind direction. Following completion of the film rewind, the cooperating elements and the shaft member are automatically disengaged from the cassette, the latter is partially ejected and the apparatus turned off. The apparatus is also configured for operation of a multipurpose cassette which includes a processor station adapted to apply processing fluid to the film strip during its first rewind following exposure, and when the cassette is unprocessed, the apparatus automatically processes the cassette during the first film transport cycle and repeats the cycle prior to cassette ejection so as to program the latter through both a process and projection mode.

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 laminating a photosensitive element to an image-receiving element by applying a layer of a film-forming agent to one of the elements, superposing the elements and distributing a layer of a second film-forming material therebetween to form an adhesive bond that is weaker than the bond between any other layers of said film unit and is adapted to rupture readily during the spreading of a processing liquid between the elements. A binding is secured around at least two sides of the laminate and a container of processing liquid is attached to one edge of the sandwich in position to eject its contents between the elements in response to the application of compressive pressure.
