Abstract

Although lithographic printing has been widely recognized and commercialized to a great extent, it has been necessary to employ hydrophilic materials in the non-imaged areas of the lithographic plate which comprise highly hydrated surface layers whose mechanical and electrical properties are therefore inherently humidity-sensitive, In particular these materials which become conductive under humid ambient conditions are not well suited for imaging by electrostatic electrophotography because a material which is highly re- sistive is required for imaging. It is to this problem to which this invention is directed.
