PROBLEM TO BE SOLVED: To obtain a metal lustrous thermal ink transfer recording medium which does not show the deterioration of a metal luster in a printed image, if the surface of an adhesive layer is uneven by providing a layer composed mainly of a resin whose glass transition point and melt viscosity are specified between the metal evaporated layer and the adhesive layer of the metal lustrous thermal ink transfer recording medium. SOLUTION: This metal lustrous thermal ink transfer recording medium consisting of at least, a colored or an uncolored ink layer, a metal evaporated layer and an adhesive layer arranged in that order on one of the faces of a base material has a layer composed mainly of a resin with a glass transition point of 65 deg.C or more and a melt viscosity of 1×10 cPs or more at 140 deg.C arranged between the metal evaporated layer and the adhesive layer. In addition, the coating amount of the layer formed between the metal evaporated layer and the adhesive layer is set to the range of 0.1-1g/m . Consequently, a luster retaining layer does not become softened excessively, if the adhesive layer is softened and melted during thermal ink transfer, and has the ink transferred retaining its original shape. Besides, the unevenness of the adhesive layer surface no longer adversely affects the metal evaporated layer, hence a print image with a superior metal luster.
