Title: Thermal transfer sheet for printing printed matter with metallic luster

Abstract: A thermal transfer sheet for printing a printed matter having a metallic luster comprised of a substrate, a deposition anchor layer, a metal deposition layer and an adhesive layer. The deposition anchor layer, the metal deposition layer and the adhesive layer are formed in this order on one surface of the substrate. The deposition anchor layer contains a linear polymer having a glass transition temperature of not less than C. by an amount of not less than 40 weight % of a total weight of the deposition anchor layer to thereby preventing the metal deposition layer from clouding due to high heat of a thermal head. The adhesive layer is formed of a mixture containing a wax and a thermoplastic resin and a composition ratio in amount of the thermoplastic resin to the wax is made smaller on a side to be contacted a transfer-receiving material than that on a side contacting the metal deposition layer along a direction of thickness of the adhesive layer to thereby provide a good appearance of the luster surface on the printed matter having an irregular surface.
