    摘要： A medium includes a heat-sensitive medium and an adhesive medium. The heat-sensitive medium includes a first base material and a first heat-sensitive layer. The first base material has a transparency. The first heat-sensitive layer has a transparency. The first heat-sensitive layer is provided on one surface of the first base material. The first heat-sensitive layer is configured to develop a first color when heated to a first temperature or higher. The adhesive medium includes a second base material and a first adhesive layer. The first adhesive layer is provided on one surface of the second base material. The heat-sensitive medium and the adhesive medium are to be superimposed such that the first heat-sensitive layer and the first adhesive layer are interposed between the heat-sensitive medium and the adhesive medium. The adhesive medium has an ultraviolet absorbance greater than an ultraviolet absorbance of the first base material.

    摘要： Provided is a thermal transfer sheet that can form a good image on both a transfer object made of a polyethylene terephthalate and a transfer object made of a polypropylene, as well as can form an image with high alcohol resistance. The thermal transfer sheet of the present invention includes a substrate, and a transfer layer including a colored layer and an adhesive layer, in which the adhesive layer has a phase-separated structure formed by a polyester and a polyolefin that are incompatible with each other, and in which the percentage of the region formed by one of the polyester and the polyolefin to the total area (100%) of the adhesive layer is 55% or more and 85% or less.
