Ink ribbon for thermal sublimation transfer process

摘要

Disclosed is an ink ribbon for thermal sublimation transfer process having ink layer(s) (2) and thermally-transferable image-protecting layer(s) (3) separately formed on one and the same surface of a substrate (1). The ink layer(s) (2) contains/contain a releasing resin, preferably a silicone-modified polyvinyl acetal resin, as the binder. The ink ribbon is applicable even to printing paper that has not been made releasable or has been made releasable but only slightly, while preventing the hot-sealing of the ink ribbon to the printing paper. The thermally-transferable image-protecting layer(s) of the ink ribbon is/are uniformly transferred onto the dye-receiving layer of printing paper. $$
