Abstract
A structure for producing images, such as microform, comprises a layer of a water soluble high molecular weight condensation product of a nitrogen compound, which is capable of giving off nitrogen upon subjecting it to energy, to form an insoluble resinous product, and thereunder a layer of an image forming material which is not soluble in water. The imaging structure may also comprise as the image forming material a layer of a composition which contains from about 50 to 100 atomic percent, and preferably from about 80 to 100 atomic percent tellurium and extended thereover a layer of an energy sensitive material, which is capable of changing, upon subjecting it to energy, its solubility such that a latent image of soluble and insoluble areas is formed upon imagewise exposure. The image is formed by dissolving the energy sensitive material in the areas where it has the greater solubility in one solvent and dissolving the portions of the image forming material in the areas where the energy sensitive material has been dissolved, in another solvent.
