  • Patent number: 11479057
    Abstract: 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.

  • Patent number: 8444757
    Abstract: This invention provides fibers made from a thermoplastic cellulose ester composition, which can maintain excellent mechanical properties still after high temperature dyeing treatment, especially suitable as fibers mixed with polyester fibers or as fabrics woven or knitted together with polyester fibers, and also provides the thermoplastic cellulose ester composition constituting the fibers. For example, this invention provides a thermoplastic cellulose ester composition containing at least 70 to 95 wt % of a cellulose fatty acid mixed ester with an average substitution degree of 2.4 to 2.8, 5 to 25 wt % of a plasticizer and 1 to 10 wt % of a cellulose acetate with an average substitution degree of 2.3 to 2.6, and also provides fibers made from the thermoplastic cellulose ester composition.
