Abstract: There is provided a heat-sensitive transfer recording medium which is able to suppress the occurrence of abnormal transfer during high-speed printing using a high-speed printer of sublimation transfer type and is able to improve transfer sensitivity in high-speed printing. The heat-sensitive transfer recording medium includes a base (10), a heat-resistant lubricating layer (20) formed on one surface of the base (10), an underlying layer (30) formed on the other surface of the base (10), and a dye layer (40) formed on a surface of the underlying layer (30) which is opposite to the surface facing the base (10). In the heat-sensitive transfer recording medium, the underlying layer (30) has a major component that is a copolymer of polyester having a sulfonic group on a side chain and acrylic having at least one of a glycidyl group and a carboxyl group.

Abstract: Provided are a thermal transfer image receiving sheet which is high in print density and good in adhesion to a substrate when high-speed printing is effected using existing high-speed printers and which can mitigate the generation of glitter even when high-speed printing is effected under high temperature and high humidity environments and also a method for fabricating the same. A thermal transfer image receiving sheet (1) related to the present embodiment is one formed by successively stacking, on one surface of a substrate (2), a heat-insulating layer (3), an undercoat layer (4) and a dye-receiving layer (5) wherein the undercoat layer (4) is comprised, as a main component, of a polycondensate formed by using at least one of an alkoxide, a hydrolyzate of an alkoxide and tin chloride, a water-soluble polymer, a vinyl pyrrolidone-vinyl imidazole copolymer, and a urethane resin.

Abstract: An excellent protective layer transfer sheet that can obtain glossy printed matter and matte printed matter from the same protective layer transfer sheet, and obtain printed matter having high image quality, foil cutting properties, and plasticizer resistance is provided. In a protective layer transfer sheet (1), a heat-resistant lubricating layer (3) is provided on a first surface of a substrate (2), and a thermally transferable protective layer (6) is provided on at least part of a second surface of the substrate (2). The thermally transferable protective layer (6) is composed of a peeling layer (4) and an adhesive layer (5). The peeling layer (4) contains cellulose acetate propionate resin having a glass transition temperature (Tg) in the range of 140°C or more and 150°C or less, and a number average molecular weight (Mn) of 30,000 or less, and polyester resin having a number average molecular weight of 15,000 or more.
