  • Thermoplastic resin sheets provided with functionality by transfer method and their production processes
    Publication number: 20070104961
    Abstract: The present invention provides a functional thermoplastic resin sheet including a thin film of at least one layer formed on at least one side of a thermoplastic resin sheet by a transfer method, wherein at least one layer of the thin film has functionality. The functional thermoplastic resin sheet of the first invention has a thin film of at least one layer formed on an uneven surface of a thermoplastic resin sheet having the uneven surface by a transfer method. The production process includes transferring, using a transfer film with a thin film of at least one layer formed on a surface of a base film, the thin film to an uneven surface of a thermoplastic resin sheet having the uneven surface, at which when the glass transition temperature of a thermoplastic resin sheet is denoted as Tg, a surface temperature of the thermoplastic resin sheet is in a range of not lower than (Tg?10° C.) and not higher than (Tg+70° C.
