ABSTRACT:
Disclosed is a process for thermal transfer impression, which comprises contacting a master image forming substrate sheet with a thermal transfer ink roll comprising as major components a wax, a coloring matter, and a low-melting-point resin, heating said substrate sheet on the side opposite to that in contact with the ink roll to impress a master image on the latter side of said substrate sheet, then bringing the impressed side of said substrate sheet in contact with an image receiving substrate sheet, and passing the resulting assembly through a heating device to transfer the impressed image to said image receiving substrate sheet. Multicolor thermal transfer impression is possible by using an ink roll divided into a plurality of ink sections of different colors.
