Abstract
The present invention relates to a heat transfer cover film characterized in that a specific transparent resin layer (2) is releasably provided on a substrate film (1). This transparent resin layer (2) can be easily laminated on the surface of the resulting image (7Y, 7M and 7C) by heat transfer means, making it possible to provide expeditious provision of image representations which are improved in terms of such properties as durability, gloss and color development and is curl-free.
