Abstract
922,682. Copying, using infra-red radiation. W. RITZERFELD, and G. RITZERFELD. May 5, 1961 [May 19, 1960], No. 16359/61. Class 98 (2). A method for use in the production of a copy of an original text to be copied comprises the steps of placing a transfer sheet having on one side thereof a transferable layer containing an ink or dye, and having directly or indirectly on the first said layer a further layer, of latently adhesive material of such nature as to become effectively adhesive when heated to a temperature above normal room temperature but below its melting temperature and below the melting temperature of the first said layer, with its layered side in contact with a further sheet, on which the copy is to be made, subjecting both layers to a differential infra-red irradiation by direct illumination through, or reflex illumination from, the original text, allowing or causing the sheets and layers to cool to below the adhesion temperature of said adhesive material and separating both sheets, portions of the further layer and the corresponding formerly underlying portions of the first said layer, which portions correspond to the original text, being removed from the transfer sheet on said separation, as a result of the adhesion of the said portions of the further layer to the further sheet. The latently adhesive layer may comprise a thermoplastic synthetic resin. The latently adhesive layer may be, for example, an isobutylene polymer, butyl rubber, abietyl alcohol or an ester of abietic acid. The transferable layer may comprise a triphenylmethane dye embedded in fat and wax. Three examples are also given of compositions for transfer layers comprising crystal violet, Victoria blue and lamp black with milori blue respectively in various wax and fat compositions. All but the last example are of use in the production of printing master sheets. If an intermediate layer is present between the transferable and latently adhesive layers it should be substantially non infra-red absorbing and may comprise for example equal amounts by weight of hard paraffin and bentonite. The original text may either be on a separate sheet or printed on the back of the sheet on which the copy is to be made.
