Abstract

968,466. Heat-sensitive photographic materials. INTERNATIONAL BUSINESS MACHINES CORPORATION, and KALVAR CORPORATION. Feb. 16, 1962 [March 6, 1961], No. 6051/62. Heading G2C. A method of copying an original which comprises placing the document in contact with a vesicular copy sheet, heating by infra-red radiation so that the areas of the sheet in contact with the image areas of the original become more heated and less sensitive to ultra-violet radiation, subjecting the heated sheet to ultra-violet radiation and heating to develop the latest image therein. The copy sheet may be mounted on a support which is preferably transparent to infra-red and ultra-violet radiations. Specification 861, 250 is referred to.
