ABSTRACT:
Provided is an image receptor for a thermal transfer ink, including a plastic film, and a coating layer which is formed on the plastic film and composed of a polyester resin of which glass transition point is 40.degree. to 6.0.degree. C., the amount of the coating layer when dried being 0.08 to 0.8 g/m.sup.2. This image receptor is adaptable for a tape printer and assures good fixing property and fastness of a printed image while exhibiting a satisfactory anti-blocking property when stored. Also provided is a thermal transfer ink sheet for forming a printed image on the image receptor, including a sequential lamination of a foundation, a release layer, a barrier layer composed of a polyester resin, and a colored layer containing 40 to 60% by weight of a polyester resin and 30 to 60% by weight of a coloring agent. This thermal transfer ink sheet is advantageously used to form on the above image receptor a printed image of good fixing property and fastness.
