Duplicating method

Claim 1

A METHOD OF FORMING DUPLICATE COPIES OF AN ORIGINAL CONTAINING THEREON INDICIA, CAPABLE OF PRODUCING LOCALIZED AREAS OF HEAT, THROUGH A PROCESS OF THERMAL REPRODUCTION, COMPRISING THE STEPS OF (A) INTERPOSING BETWEEN SAID ORIGINAL AND A MASTER RECEPTOR TISSUE A TISSUE CONTAINING DITHIOXAMIDE THEREBY TO FORM A FIRST ASSEMBLY COMPRISING SAID ORIGINAL, SAID MASTER RECEPTOR TISSUE AND SAID DITHIOXAMIDE-CONTAINING TISSUE IN INTIMATE SURFACE CONTACT; (B) EXPOSING SAID FIRST ASSEMBLY TO RADIANT FLUX OF SUFFICIENT INTENSITY AND DURATION TO GENERATE IN SAID INDICIA SUFFICIENT LOCALIZED HEAT TO SUBLIME AT LEAST A PORTION OF SAID DITHIOXAMIDE CORRESPONDING IN AREA TO SAID INDICIA ON SAID ORIGINAL AND IN DIRECT PROPORTION TO THE ABILITY OF SAID INDICIA TO ABSORB AND TRANSMIT HEAT WHEREBY SAID DITHIOXAMIDE IS TRANSFERRED TO SAID MASTER RECEPTOR TISSUE TO FORM A MASTER TISSUE; (C) CONTACTING SAID MASTER TISSUE WITH A COPY SHEET TO FORM A SECOND ASSEMBLY, SAID COPY SHEET CONTAINING METALLIC IONS AVAILABLE FOR REACTION WITH SAID DITHIOXAMIDE TO FORM A WATER-INSOLUBLE CHROMOPHORIC COMPLEX; AND (D) HEATING SAID SECOND ASSEMBLY THEREBY TO SUBLIME A PORTION OF SAID DITHIOXAMIDE TO CONTACT SAID COPY SHEET AND REACT WITH SAID METALLIC IONS THEREIN THEREBY TO FORM A DUPLICATE OF SAID INDICIA IN SAID COPY SHEET.
