Kind Code:
B2
Abstract:
Disclosed is a thermal transfer sheet capable of imparting sufficient abrasion resistance and light fastness simultaneously to a transfer layer and capable of inhibiting a dye that has been kicked to the back side of the thermal transfer sheet from backing to the surface of the transfer layer.A thermal transfer sheet 100 comprising a dye layer 7 and a transfer layer 10 provided on one surface of a substrate 1, as being frame sequentially, wherein: the transfer layer 10 has a layered structure comprising a protective layer 2 and an adhesive layer 3 layered in this order from the side of the substrate 1; the adhesive layer 3 contains two or more resin components; one of the two or more resin components is a copolymer of a reactive ultraviolet absorbing agent and an acrylic monomer; in the copolymer of the reactive ultraviolet absorbing agent and the acrylic monomer, the copolymerization ratio of the reactive ultraviolet absorbing agent is in the range of 10% or more and 50% or less on a molar ratio basis and the copolymerization ratio of the acrylic monomers is in the range of 50% or more and 90% or less on a molar ratio basis; and the content of the copolymer of the reactive ultraviolet absorbing agent and the acrylic monomer is specified in the range of 50% by mass or more and 90% by mass or less on the basis of the total mass of the adhesive layer.
