    • Coated paper substrates having a high gloss suitable for vacuum metallization are manufactured by a direct coating method which comprises laminating an interleaving film and the thermoplastic resin-coated surface of a paper substrate employing suitable temperatures and pressure to render the thermoplastic flowable and thereafter nonflowable. The interleaving film is than stripped away leaving the resin-coated paper substrate with a high specular gloss which can thereafter be vacuum metallized.
      Similar high gloss paper substrates are also provided by a transfer coating process which comprises laminating a paper substrate and the thermoplastic resin-coated surface of a transfer film employing sufficient temperatures and pressure to first render the thermoplastic resin flowable and then nonflowable and thereafter stripping away the transfer film.
      Paper substrates having 75° specular gloss readings of at least 85 prepared by a process of this invention are then vacuum metallized resulting in the manufacture of highly reflective metallized paper.
    • 通过直接涂布方法制造具有适用于真空金属化的高光泽度的涂布纸基材,其包括使用合适的温度和压力层压交织膜和纸基材的热塑性树脂涂覆表面,以使热塑性塑料流动并且之后不可流动。 交错膜被剥离,留下具有高镜面光泽度的树脂涂布纸基材,此后可以真空金属化。 通过转印涂布方法也提供了类似的高光泽纸基材,其包括使用足够的温度和压力层压纸基材和转印膜的热塑性树脂涂覆表面,以首先使热塑性树脂流动然后不可流出,然后剥离 转移膜。 然后通过本发明的方法制备的具有至少85°的75°镜面光泽读数的纸基材被真空金属化,从而制造高反射性金属化纸。
