ABSTRACT:
A photosensitive article comprises a substrate of a triacetate or other polyester film or paper coated with a layer of a photosensitive composition. The photosensitive composition includes at least one photodissociable choline compound sensitive to x-rays or radiation of shorter wave lengths, at least one image-forming compound capable of producing a dye by reaction with the dissociation products of the choline compound, a water soluble polymeric binder and a low melting point fatty acid salt for heat development. The photosensitive article can be used to produce an x-ray image by exposing the article image-wise to x-rays and heating the exposed article to develop the image.
