Abstract

A metal film-coated molded resin article includes: 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 includes: 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 measured under the adhesion test described in appendix 1 (specifications) of JIS H8630:2006 is ≥9.0 N/cm. A metal film-coated molded resin article may include a metal film excellent in adhesion, formed on the surface of the 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.

First claim

1 . A metal film-coated molded resin article, comprising:
a molded article comprising a polybutylene terephthalate-comprising resin composition and/or a polycarbonate-comprising resin composition; and a metal film disposed on a surface of the molded article, wherein the resin composition(s) comprises a reactive compound and/or a resin comprising a reactive functional group.

2 . A metal film-coated molded resin article, comprising:
a molded article comprising a polybutylene terephthalate-comprising resin composition; and a metal film disposed on a surface of the molded article, wherein the metal film has a peel strength, measured according to an adhesion test method described in appendix 1 (specifications) of JIS H8630:2006, of 9.0 N/cm or more.

3 . The article of claim 2 , wherein the polybutylene terephthalate-comprising resin composition comprises the reactive compound and/or the resin comprising a reactive functional group.

4 . The article of claim 1 , wherein the reactive compound and/or the resin having the reactive functional group is a compound comprising an amide group and/or a resin comprising an amide group.

5 . The article of claim 4 , wherein the resin comprising the amide group is a polyamide resin.

6 . A plating film-coated molded article, comprising:
the metal film-coated molded resin article of claim 1 ; and a plating layer disposed on the metal film.

7 . A vehicle-mounted component comprising:
the plating film-coated molded article of claim 6 .

8 . An electrical component comprising:
the plating film-coated molded article of claim 6 .

9 . A resin composition useful for producing the metal film-coated molded resin article including a metal film formed on a surface of a molded polybutylene terephthalate-based resin article and/or a surface of a molded polycarbonate-based resin article using a dry process, the resin composition comprising a reactive compound and/or a resin having a reactive functional group.

10 . A method for producing the metal film-coated molded resin article of claim 1 , the method comprising:
depositing the metal film on a surface of a molded polybutylene terephthalate resin-based article and/or a surface of a molded polycarbonate-based resin article using a dry process.

11 . The method of claim 10 , wherein, after the surface of the molded polybutylene terephthalate resin-based article and/or the surface of the molded polycarbonate-based resin article is subjected to plasma treatment in a vacuum atmosphere, the metal film is deposited on the plasma-treated surface(s) by sputtering.

12 . A method for producing a plating film-coated molded article, the method comprising:
forming a plating layer on the metal film of the metal film-coated molded resin article produced in claim 11 .

13 . The article of claim 1 , wherein the reactive compound comprises an epoxy compound and/or the reactive functional group comprises an epoxy group.

14 . The article of claim 4 , wherein the resin composition further comprises an epoxy compound and/or a resin comprising an epoxy group.

15 . The article of claim 2 , wherein the reactive compound and/or the resin having the reactive functional group is a compound comprising an amide group and/or a resin comprising an amide group.

16 . The article of claim 15 , wherein the resin comprising the amide group is a polyamide resin.

17 . A plating film-coated molded article, comprising:
the metal film-coated molded resin article of claim 2 ; and a plating layer disposed on the metal film.

18 . A vehicle-mounted component, comprising:
the plating film-coated molded article of claim 17 .

19 . An electrical component, comprising:
the plating film-coated molded article of claim 17 .

20 . A method for producing the metal film-coated molded resin article of claim 2 , the method comprising:
depositing the metal film on a surface of a molded polybutylene terephthalate resin-based article and/or a surface of a molded polycarbonate-based resin article using a dry process.
