Patent number: 11479057Abstract: An intermediate transfer medium that allows formation of high-density images on a transfer layer while suppressing printing unevenness and provides good foil cutting properties of the transfer layer, a combination of the intermediate transfer medium and a thermal transfer sheet, and a method for forming a print using the intermediate transfer medium. In an intermediate transfer medium having a transfer layer on a substrate, the transfer layer has a single layer structure including only a receiving layer or a layered structure including the receiving layer. When the transfer layer has the layered structure, the receiving layer is located furthest from the substrate among layers constituting the transfer layer. The receiving layer contains a binder resin having a number average molecular weight of 8000-32000 and a release agent. The content of the release agent based on the total mass of the receiving layer is 6% by mass or more.Type: GrantFiled: April 23, 2021Date of Patent: October 25, 2022Assignee: Dai Nippon Printing Co., Ltd.Inventors: Shinya Yoda, Yasushi Yoneyama
