ABSTRACT:
A process is provided for transfer printing into a substrate comprising applying onto a temporary transfer support in a desired pattern a heat transfer printing ink composition comprising a sublimatable dye, fine powder graphite and a strong acid in a carrier liquid, bringing the transfer support containing the ink into close contact with the substrate, the ink being in direct contact with the substrate, thereby temporarily transferring a portion of the ink to the substrate as a result of the direct contact, and permanently transferring the ink into the substrate by applying heat and, optionally, pressure. Suitable substrates into which the desired pattern may be transferred include paper, wood, plastic, natural cloth, synthetic cloth, carpet material, concrete, glass, metal such as steel, porcelain and ceramic. The process may include applying the ink to the transfer support by a computerized process including inputting an image of a desired pattern into a computer central processing unit having a keyboard and a peripheral video display terminal and printer by means of an optical character reader, employing in the printer the heat transfer printing ink composition of the invention, and printing the desired pattern onto conventional computer paper, the computer paper becoming the temporary transfer support. The process may include a modem and the printer may be located remote from the central processing unit and printing may be accomplished by the printer via the modem.
