The present invention provides an adhesive composition comprising a copolymer (a) of a methylmethacrylate (MMA) and/or a butylmethacrylate (BMA) and a styrene (St), also provides an adhesive composition comprising a mixture of an acrylic polymer (b) and a ketone resin, wherein the acrylic polymer (b) is at least one polymer selected from the group consisting of a poly MMA, a poly BMA, a MMA/BMA copolymer or a MMA/BMA/St copolymer, and also provides a thermal transfer sheet having a layer comprising the adhesive composition. The adhesive composition has excellent heat sealing characteristics and resistance to blocking when it is used for the formation of an adhesive layer, is also superior in miscibility with various organic or inorganic additives and allows these additives to exhibit their functions sufficiently when these additives are added and has high transparency.

Adhesive composition and thermal transfer sheet

The present invention is first directed to a thermal transfer sheet which is not high in cost for obtaining a substrate, does not involve a problem of blocking or the like at the time of winding after coating of a backside layer onto the substrate, can eliminate the need to provide a release layer on the protective layer region, and further can enhance glossiness of a print with a protective layer. The thermal transfer sheet comprises a substrate, a dye layer of at least one color and a thermally transferable protective layer provided in a face serial manner on one side of the substrate, a protective layer provided on a part of one side of the substrate, an easy-adhesion layer provided on the whole surface of the protective layer and the substrate, the dye layer being provided on the easy-adhesion layer in its region where the protective layer is not located on the underside of the easy-adhesion layer. The second invention is directed to a thermal transfer sheet which can cope with increased printing speed in the thermal transfer, can meet demands for the provision of thermally transferred images having high density and high quality, can prevent the occurrence of abnormal transfer, cockles, etc., and can improve sensitivity in transfer at the time of printing. The thermal transfer sheet according to the second invention comprises a substrate, a heat-resistant slip layer provided on one side of the substrate, and an adhesive layer and a dye layer provided in that order on the other side of the substrate, the adhesive layer comprising a polyvinylpyrrolidone resin. By virtue of this construction, the sensitivity in transfer can be significantly improved at the time of thermal transfer, and a high-density thermally transferred image can be provided without applying high energy.

Thermal transfer sheet

The present invention provides a protective layer transfer sheet which, when used to thermally transfer a protective layer onto an image-receiving sheet with an image formed thereon, provides a print that does not cause cracking of the protective layer and, even when housed and stored in a vinyl chloride case containing a plasticizer or the like, does not cause the migration of a dye constituting the image to the case, that is, has excellent fastness properties. In a protective layer transfer sheet comprising a substrate sheet , a heat-resistant slip layer provided on one side of the substrate sheet , and a thermally transferable protective layer releasably provided on at least a part of the surface of the substrate sheet remote from the heat-resistant slip layer , the thermally transferable protective layer contains an epoxy resin and, in addition, contains at least one member selected from the group consisting of a butyral resin, an acrylic resin, and an ultraviolet absorber. By virtue of this construction, a protective layer is strongly adhered onto an image-receiving sheet with an image formed thereon. Further, the protective layer is strong and homogeneous, and, thus, even when the print is housed in a vinyl chloride case, the print does not cause the dye to migrate to the case, that is, has excellent plasticizer resistance.
