Claim 3
Independent Claim
109 words
THE METHOD OF FORMING A PLASTIC DEFORMATION IMAGE COMPRISING THE STEPS OF: (A) PROVIDING A FILM COMPRISING A SOFTENABLE MATERIAL WHICH HAS AN ELECTRICAL RESISTIVITY GREATER THAN ABOUT 10**10 OHM-CENTIMETERS AT ITS SOFTENING POINT AND IS CAPABLE OF ACCEPTING AND MECHANICALLY RESPONDING TO A CHARGE PATTERN DEPOSITED ON A FILM OF SAID MATERIAL TO FORM SURFACE WRINKLES, AND A PHOTOPOLYMER; (B) FORMING AN ELECTROSTATIC LATENT IMAGE ON THE SURFACE OF SAID FILM; (C) SOFTENING SAID FILM WHEREBY THE SURFACE WRINKLES IN IMAGE CONFIGURATION; AND (D) EXPOSING SAID FILM TO ELECTROMAGNETIC RADIATION OF A FREQUENCY WHICH CAUSES POLYMERIZATION OF SAID PHOTOPOLYMER THEREBY PERMANENTLY HARDENING AND FIXING SAID PLASTIC DEFORMATION IMAGE.
