Abstract

Abstract Anink ribbon for a sublimation transfer type hard copy is employed to obtain a hard copy from a static image, such as an image picked up by a video camera or a TV image. The ink ribbon for a sublimation transfer type hard copy is obtained by forming a coating layer of a sublimating dye on a heat-resistant plastic film base or a plastic film base having a layer which has been given a heat-resistant treatment. With this ink ribbon, it is possible to prevent the shrinkage of the film base as a result of heat during the transfer operation and the production of foaming marks in the film base. Accordingly, the quality of the transferred image is improved.
