ABSTRACT:
An imaging method involves a substrate having a coating which undergoes a photochemical conversion upon being irradiated to yield only products whose vapor pressure under the operative temperature is higher than that of the coating. In this way as a result of the selective vaporization of the coating the desired image is obtained. The new method has wide applications such as photography, production of microfilms, electrophotographic document duplication, production of master prints for offset printing, etc.
