Photoplastic Recording Material

Formation of relief images in thermoplastic materials heretofore has required the corona charging of the material surface, radiant exposure and relief formation via the application of either solvent vapors or heat.

There has been found a class of materials for relief image formation that eliminates the necessity of the corona charging and, in certain cases, of any processing following optical exposure.

In particular, it has been observed that when any of the following compositions are coated on a substrate and irradiated with an optical image, a corresponding relief image is formed. Depending on the binder used, the relief image is formed immediately upon evaporation of the solvent, following exposure, or by the subsequent application of heat.
