  • Publication number: 20080152875
    Abstract: This invention provides a transfer foil, which, even in a relief formation layer formed of a highly heat resistant material, can realize good embossing properties of a relief structure and good printing durability of a embossing stamper, and, even in transfer, for example, using a thermal printer, can realize good transferability of a high-definition image, and an image formed object using the transfer foil. The transfer foil comprises a base material, a peel layer, a relief formation layer, and a reflective layer formed in that order. The transfer foil is characterized in that the peel layer comprising at least a thermoplastic resin having a glass transition temperature of 120 to 200° C. and the relief formation layer being formed of a cured product of an ionizing radiation curable resin.
