(57) Abstract: A layer containing a dye sublimated by heat is laminated on one surface of a biaxially oriented polyester film via an easy-adhesion layer, and an anti-stick layer is provided on the other surface. A sublimation-type thermal transfer material, wherein the easy-adhesion layer has a phase-separated structure in the thickness direction, and a mixed phase of each phase is present at the phase-separated interface. [Effect] The sublimation-type thermal transfer material produced by the present invention has excellent adhesiveness to a layer containing a dye that is sublimated by heat, and also has excellent adhesiveness under high temperature and high humidity, and has excellent ink resistance during printing.
