Abstract
Abstract AN IMPROVED IMAGING PROCESS FOR ELECTRON BEAM RECORDING IS DISCLOSED. IN THIS PROCESS, A LAYER OF A HIGHLY VISCOUS PHOTOPOLYMER IS EXPOSED TO AN ELECTRON BEAM IN A VACUUM. IT HAS BEEN FOUND THAT THE ELECTRON BEAM SIMULTANEOUSLY CAUSES THE FORMATION OF A SURFACE DEFORMATION IMAGE WHILE POLYMERIZING THE MATERIAL IN EXPOSED AREAS. THUS, AN INSTANTANEOUS VISIBLE IMAGE IS FORMED WITH NO POST PROCESSING OF THE MATERIAL REQUIRED. BACKGROUND AREAS OF THE MATERIAL MAY BE POLYMERIZED BY EXPOSURE TO SUITABLE RADIATION, SUCH AS ULTRA VIOLET LIGHT, IN THE SUBSTANTIALY ABSENCE OF OXYGEN. THIS PRODUCES A STRONG, EASILY HANDLED IMAGED SHEET.
