  • Patent number: 8475891
    Abstract: This invention provides an embossed release paper that has high heat resistance and embossing properties. The embossed release paper comprises a paper base material, an ionizing radiation-cured resin layer, and a heat-cured silicone layer stacked in that order, the embossed release paper having embosses. The embossed release paper has high heat resistance and thus is suitable for use in synthetic leather production and melamine decorative sheet production that involve surface emboss pattern formation.
