Abstract
Abstract A sheet for sublimation transfer recording which is characterized by being composed of a base coated with an ink for sublimation heat-sensitive transfer and further coated with a heat-resistant resin such as a water-soluble cellulose type derivative, e.g., methyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxypropylmethyl cellulose or hydroxybutylmethyl cellulose. The obtained recording has good definition and shows no abrasion staining in the non-printed part of the image receiving body, and peeling-off of the recording sheet from the image receiving body is easy.
