  • Patent number: 7514138
    Abstract: An object of the present invention is to provide a hydraulic transfer film with a transfer layer capable of forming a cured resin layer on a hydraulic transfer body, to provide a hydraulic transfer film capable of forming a clear decorative layer on a curable resin layer, and a hydraulic transfer body having excellent surface properties and a clear pattern. A hydraulic transfer film having a water-soluble substrate film, a hydrophobic transfer layer including a curable resin layer which can be cured by at least one of irradiation with radiation and heating provided on the substrate film, and a peelable film provided on the transfer layer is described along with a method for producing the hydraulic transfer film.

  • Publication number: 20070042163
    Abstract: A film for hydraulic transfer having a supporting film formed from a water-soluble or water-swelling resin, and a transfer layer that is soluble in organic solvent provided on top of the supporting film, in which the transfer layer includes a curable resin layer that is curable by irradiation with an active energy beam, and a decorative layer composed of an ink or a coating film, wherein the curable resin layer is non-adhesive at room temperature, and contains: 1) a non-polymerizable thermoplastic resin (A), and, 2) a radical polymerizable oligomer (B1), having a weight average molecular weight within a range from 700 to 3,000 and being compatibility with the non-polymerizable thermoplastic resin (A).
