ABSTRACT:
An improved slide for electrophotographic film which comprises a pair of slide frame forming panels hingedly connected along adjacent edges enabling the panels to be folded together in superposed relation. The inner surfaces of each panel is coated with a pressure sensitive adhesive which bonds an electrophotographic film to one panel. A transparent protective film or a second photographic film may be bonded to the other panel. A conductive foil strip is affixed along an edge of the film for providing a grounding contact required for imaging the film in a duplicating camera and a release paper is disposed over the adhesive coating of the other panel. Subsequent to imaging, a slide is formed by stripping off the release paper and folding the panels so that the adhesive coating bonds the inner surfaces together with the film being retained therebetween.
