An object of the present invention is to provide a thermal transfer sheet capable of imparting sufficient abrasion resistance and light resistance to a transfer layer at the same time, and suppressing whitening of dye kicked toward the back side of the thermal transfer sheet to the surface of the transfer layer. do. The thermal transfer sheet is a thermal transfer sheet 100 in which a dye layer 7 and a transfer layer 10 are sequentially formed on one side of the substrate 1, the transfer layer 10 being the substrate 1 From the side, the protective layer 2 and the adhesive layer 3 are laminated in this order to show a laminated configuration, wherein the adhesive layer 3 contains two or more resin components, and one of the two or more resin components is a reactive type. It is a copolymer of a UV absorber and an acrylic monomer, and the copolymerization ratio of the reactive UV absorber in the copolymer of the reactive UV absorber and the acrylic monomer is in the range of 10% or more and 50% or less in terms of molar ratio, and the copolymerization ratio of the acrylic monomer is The molar ratio is in the range of 50% or more and 90% or less, and the content of the copolymer of the reactive ultraviolet absorber and the acrylic monomer is defined in the range of 50% by mass or more and 90% by mass or less with respect to the total mass of the adhesive layer. do. |
