Process for producing resin molded article

1. A process for producing a resin molded article, comprising the steps of

forming a high-pressure fluid by dissolving, in a high-pressure carbon dioxide, a fluorine-containing metal complex and a fluorine-based solution capable of dissolving said metal complex,

introducing said high-pressure fluid into a heated and molten resin, and

molding the resin into which said high-pressure fluid has been introduced, to shape the resin molded article.

2. The process of claim 1 , wherein the dissolution of said fluorine-containing metal complex and said fluorine-based solution in said high-pressure carbon dioxide comprises the steps of

dissolving said fluorine-containing metal complex in said fluorine-based solution, and

dissolving, in said high-pressure carbon dioxide, said fluorine-based solution in which said fluorine-containing metal complex is dissolved.

3. The process of claim 2 , wherein the dissolution of said fluorine-containing metal complex in said fluorine-based solution comprises the steps of

dissolving said fluorine-containing metal complex in said fluorine-based solution to form a mixture solution, and

allowing said mixture solution to have a high pressure.

4. The process of claim 1 , wherein the dissolution of said fluorine-containing metal complex and said fluorine-based solution in said high-pressure carbon dioxide comprises the steps of

dissolving and saturating said fluorine-containing metal complex and said fluorine-based solution in a first high-pressure carbon dioxide, and

mixing said first high-pressure carbon dioxide in which said fluorine-containing metal complex and said fluorine-based solution are dissolved and saturated, with a second high-pressure carbon dioxide in which any of said fluorine-containing metal complex and said fluorine-based solution is not dissolved.

5. The process of claim 1 , using an injection-molding apparatus comprising a mold and a heating cylinder which heats and melts said resin and injects the heated and molten resin into said mold, wherein the introduction of said high-pressure fluid into said heated and molten resin comprises the step of introducing said high-pressure fluid into said resin which is heated and molten in said heating cylinder; and the molding of said resin into which said high-pressure fluid is introduced comprises the step of injecting said resin into which said high-pressure fluid is introduced, into said mold from said heating cylinder.

6. The process of claim 1 , further comprising a step of subjecting, to a heat treatment, said molded article shaped of said resin into which said high-pressure fluid is introduced.

7. The process of claim 1 , further comprising a step of subjecting, to a vacuuming treatment, said molded article shaped of said resin into which said high-pressure fluid is introduced.

8. The process of claim 1 , wherein said fluorine-based solution has a boiling point of from 150 to 400° C.

9. The process of claim 1 , wherein the molecular weight of said fluorine-based solution is from 500 to 15,000.

10. The process of claim 1 , wherein a high-pressure carbon dioxide having a pressure of from 5 to 25 MPa is used as said high-pressure carbon dioxide in which said fluorine-containing metal complex and said fluorine-based solution are dissolved.

11. The process of claim 1 , wherein said metal complex is hexafluoroacetylacetonatopalladium (II) or nickel (II) hexafluoroacetylacetonatohydride, and wherein said fluorine-based solution is perfluorotripentylamine or perfluoro-2,5,8,11,14-pentamethyl-3,6,9,12,15-pentaoxaoctadecanoyl fluoride.

12. The process of claim 1 , further comprising a step of forming a metal film on said molded article.

13. The process of claim 12 , wherein the formation of said metal film on said molded article comprises a step of bringing said molded article into contact with a fluid in which another high-pressure carbon dioxide is compatiblized with a plating solution.
