  A metal film-coated molded resin article comprising: a molded article formed of a polybutylene terephthalate-based resin composition and/or a polycarbonate-based resin composition; and a metal film disposed on a surface of the molded article, wherein the resin composition(s) contain(s) a reactive compound and/or a resin having a reactive functional group. A metal film-coated molded resin article comprising: a molded article formed of a polybutylene terephthalate-based resin composition; and a metal film disposed on a surface of the molded article, wherein the peel strength of the metal film that is measured according to an adhesion test method described in appendix 1 (specifications) of JIS H8630:2006 is 9.0 N/cm or more. Provided is a metal film-coated molded resin article in which a metal film excellent in adhesion is formed on the surface of a molded resin article such as a molded polybutylene terephthalate based-resin article and/or a molded polycarbonate-based resin article using a dry process instead of electroless plating.

  一种金属膜包覆的模压树脂制品，包括：由聚对苯二甲酸丁二酯基树脂组合物和/或聚碳酸酯基树脂组合物形成的模压制品；以及设置在模压制品表面的金属膜，其中树脂组合物含有活性化合物和/或具有活性官能团的树脂。一种涂有金属膜的模塑树脂制品，包括：由聚对苯二甲酸丁二醇酯基树脂组合物形成的模塑制品；以及设置在模塑制品表面的金属膜，其中，根据 JIS H8630:2006 附录 1（规格）中描述的附着力测试方法测量的金属膜剥离强度为 9.0 N/cm 或以上。本发明提供了一种金属膜涂层模塑树脂制品，在该制品中，使用干法工艺而不是无电解电镀法，在模塑树脂制品（例如模塑聚对苯二甲酸丁二酯基树脂制品和/或模塑聚碳酸酯基树脂制品）的表面形成了附着力极佳的金属膜。
