    Abstract: A POROUS, INK CONTAINING TRANSFER MEDIUM IS PREPARED BY COATING THE SURFACE OF A POLYMER FILM, SUCH AS A POLYAMIDE, WITH A PORE FORMING AGENT, SUCH AS AMMONIUM BICARBONATE, CONTAINED IN A SOLVENT SUCH AS ETHANOL, WHICH IS AT LEAST A PARTIAL SOLVENT FOR THE POLYMER FILM, TO IMPREGNATE A PORTION OF THE PORE FORMING AGENT INTO THE SURFACE OF THE POLYMER FILM. THE SOLVENT IS REMOVED AND THE FILM IS HEATED TO CAUSE THE PORE FORMING AGENT TO VAPORIZE AND FORM AN OPEN PORED CAPILLARY STRUCTURE IN THE SURFACE OF THE FILM. THE MARKING MATERIAL CAN BE INCORPORATED EITHER WITH THE PORE FORMING EITHER WITH THE PORE FORMING AGENT OR AFTER THE OPEN PORED CAPILLARY STRUCTUE HAS BEEN FORMED.

    Abstract: Ink receptive convertible films suitable for use in copying systems or projection slides are prepared by coating the surface of a transparent film with a fusible polymer material such as polyvinyl acetate with a pore forming agent such as ammonium carbonate. The polymer containing the pore forming agent to volatilize and render the film porous, and ink receptive. The film is then readily printed with a conventional ink after which the nonprinted portion of the opaque coating is rendered transparent through the application of heat and/or pressure, or the action of solvent vapors. The printed matter substantially retains the print quality it possessed during the ink receptive opaque stage.

    Abstract: A MULTICOLOR TRANSFER MEDIUM IS PROVIDED BY A PROCESS WHICH COMPRISES MAKING A FIRST MATRIX MATERIAL BY MIXING A FLUID TRANSFER INK OF A FIRST COLOR WITH A SOLUTION OF A FILM FORMING POLYMER IN A SOLVENT FOR THE POLYMER, COATING THE RESULTING DISPERSION ON A FIRST SUBSTRATE AND EVAPORATING THE SOLVENT TO FORM THE MATRIX MATERIAL OF A FIRST COLOR. A MATRIX MATERIAL OF A SECOND COLOR IS FORMED IN AN IDENTICAL MANNER UTILIZING A FLUID TRANSFER INK OF A SECOND COLOR. THE TWO SUBSTRATES SUPPORTING THE MATRIX MATERIALS ARE

    THEN PLACED IN ADJACENT EDGE ALIGNED RELATIONSHIP TO ONE ANOTHER ON A THIRD SUBSTRATE WHICH HAS BEEN COATED WITH A FUGITIVE ADHESIVE AND A POLYMER IS THEREAFTER BACK COATED OVER THE TWO MATRIX MATERIALS TO SEAL THEM TOGETHER. THE RESULTING UNITARY MULTICOLORED TRANSFER MEDIUM IS THEN STRIPPED FROM THE SUBSTRATES AND SLIT, IF REQUIRED, TO A DESIRED WIDTH.
