PROBLEM TO BE SOLVED: To effect free discoloration in design colors or the like through variation in temperature, and enhance the strength of antiabrasion by laminating successively a resin layer, reversible thermal discoloration resin containing reversible thermal discoloration pigment and resin, and pressure sensitive adhesive resin layer on one surface of a support directly or through a release layer. SOLUTION: Coating comprising 10 pts. of polyurethane resin emulsion or the like is applied as a resin layer 3 on the surface of a PET film strip support 2 by direct coating. In the next place, after ink comprising a 100 pts. of reversible thermal discoloration pigment with reversible thermal discoloration composition contained in a microcapsule is applied as a reversible thermal discoloration resin layer 4, an acrylic pressure-sensitive adhesive agent is applied and dried as a pressure-sensitive adhesive resin layer 5 so as to obtain a reversible thermal discoloration pressure-sensitive transfer tape 1. If the pressure sensitive adhesive agent layer 5 side of the reversible thermal discoloration pressure-sensitive transfer tape 1 is stuck on a character-written paper face, and then the support 2 is released, the resin layer and reversible thermal discoloration resin layer are transferred on the characters. |
