发明名称 INTERMEDIATE TRANSFER MEDIUM, AND COMBINATION OF INTERMEDIATE TRANSFER MEDIUM AND HEAT TRANSFER SHEET
摘要 The disclosed are an intermediate transfer medium which excels in peel-off property on removing a transfer layer which include a protective layer with the aid of a peel-off layer of a thermal transfer sheet, and which imparts a high durability to a print which is formed by transferring the transfer layer to a transfer receiving article, and which retransfers the transfer layer onto the transfer receiving article without any problem; and a combination of the intermediate transfer medium and a thermal transfer sheet. The intermediate transfer medium 10 of a first aspect comprises a substrate sheet 1, a protective layer 3 and a receiving layer 4 which are layered on a surface of the substrate sheet 1; wherein the protective layer 3 comprises a blend of two or more kinds of binder resins which have mutually different number average molecular weights (Mn), and wherein a sum total (ˆ‘) of products, each product being calculated by multiplying the number average molecular weight (Mn) of individual binder resin and its content ratio in the blend together, is in the range of not less than 3000 and not more than 17000. The combination of the second aspect comprises the intermediate transfer medium and the thermal transfer sheet, wherein the intermediate transfer medium comprises a substrate, a protective layer and a receiving layer which are layered in this order on a surface of the substrate sheet, wherein the protective layer comprises a polyester resin having a number average molecular weight (Mn) of not less than 5000 and not more than 15000, and wherein the thermal transfer sheet comprises another substrate, and a peel-off layer which is provided on a surface of the another substrate, wherein the peel-off layer includes one or more kinds of resins selected from the group consisting of acrylic resins, vinyl chloride - vinyl acetate copolymer resins and polyester resins.
