Abstract:
A method for providing film record cards whereby a film-forming solution, emulsion or latex is poured into the aperture of a card structure while said card structure is supported on a base which is nonadherent to said film, and is dried so as to form a strongly adherent film to the peripheral edges of said aperture. Film record cards prepared by the foregoing method.
Abstract:
A METHOD FOR PREVENTING LOSS OF PHOTOGRAPHIC SPEED OF AN OXYGEN SENSITIVE PHOTORESIST BY PROVIDING A LAYER OF INERT GAS PRODUCING MATERIAL OVER THE STANDARD PHOTORESIST. THE GAS PRODUCING MATERIAL LIBERATES GAS DURING THE EXPOSURE STEP THUS PROTECTING THE RESIST.
Abstract:
A photographic element for producing vesicular images having extended latitudes and low gradations comprising two or more superimposed layers, each comprising a binder material and a photosensitive compound capable of decomposing upon exposure to light to form gas wherein each of said binder materials has a different permeability to gas. A process for producing vesicular images having extended latitudes and low gradations comprising imagewise exposing the above-described photographic elements to light to decompose the photosensitive compounds and heating the element to develop the vesicular images.
