Abstract
Abstract A resin laminate comprising a layer of styrene-based polymer having mainly syndiotactic configuration and a thermoplastic resin layer, a metallized laminate comprising a layer of the styrene-based polymer described above and a metal layer, and process for producing these laminates are disclosed. In the laminated the styrene-based polymer layer and the thermoplastic resin layer may be biaxially stretched. The laminates are expected to be utilized for electrostatic capacitors, hot stamping foils, flexible printed circuit board substrates, food wrapping films, and other functional films including magnetic tapes, and ornament films.
