Abstract
The present invention relates to a release sheet and an adhesive tape which display excellent releasability from an adhesive layer, excellent printing and print recordability for thermal transfer systems using an ink ribbon or the like, little susceptibility to slipping when release agent layers are placed together, little susceptibility to blocking, and no ink soiling.A release sheet of the present invention is a thermal transfer recordable release sheet with a release agent layer of a release agent composition provided on at least one surface of a substrate, wherein the release agent composition comprises at least one thermoplastic resin and/or thermoplastic elastomer selected from a group consisting of polyurethane resins, polyester resins, polyamide resins, ethylene-vinyl acetate copolymers, long chain alkyl compounds produced by reacting a vinyl acetate (co)polymer and an alkyl isocyanate, polyisobutylenes, butyl rubbers, brominated butyl rubbers, chlorinated butyl rubbers, polyisoprenes and polybutadienes, as well as a polydimethylsiloxane, and an adhesive tape of the present invention is a tape in which an adhesive layer is provided on such a release sheet, on the opposite surface to the release agent layer.
