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.
