Abstract

Provided is a resin composition having higher platability. The resin composition contains at least two kinds of metals and also containing a conductive oxide having a resistivity of 5×10 3 Ω·cm or less.

First claim

The invention claimed is:

1. A resin composition comprising a thermoplastic resin, and a laser direct structuring additive containing at least two kinds of metals and also containing a conductive oxide having a resistivity of 5×10 3 Ω·cm or less.

2. The resin composition according to claim 1 , wherein the laser direct structuring additive contains at least a metal of Group n, wherein n is an integer of 3 to 16, and a metal of Group n+1 of the periodic table.

3. The resin composition according to claim 2 , wherein an amount of one of the metal of Group n, wherein n is an integer of 3 to 16, and the metal of Group n+1 of the periodic table contained in the laser direct structuring additive is 15 mol % or less provided that the total amount of the metals is 100 mol %.

4. The resin composition according to claim 2 , wherein n is 12.

5. The resin composition according to claim 2 , wherein the metal of Group n, wherein n is an integer of 3 to 16, of the periodic table is zinc.

6. The resin composition according to claim 2 , wherein the metal of Group n+1 of the periodic table is aluminum.

7. The resin composition according to claim 1 , wherein the thermoplastic resin comprises resin components including 40 to 100% by weight of a polycarbonate resin and 0 to 60% by weight of a styrene-based resin, a polyamide resin, or a thermoplastic polyester resin.

8. The resin composition according to claim 1 , further comprising a glass filler.

9. The resin composition according to claim 1 , further comprising a silicate mineral.

10. The resin composition according to claim 9 , wherein the silicate mineral is talc.

11. The resin composition according to claim 1 , further comprising a non-conductive metal oxide.

12. The resin composition according to claim 11 , wherein the non-conductive metal oxide is a titanium oxide.

13. A resin molded article obtained by molding the resin composition according to claim 1 .

14. The resin molded article according to claim 13 , having a plated layer on a surface of the resin molded article.

15. The resin molded article according to claim 14 , wherein the plated layer has performance as an antenna.

16. The resin molded article according to claim 13 , which is a part for portable electronic devices.

17. A process for preparing a resin molded article having a plated layer, comprising irradiating a surface of a resin molded article obtained by molding the resin composition according to claim 1 with a laser beam, and then applying a metal to form the plated layer.

18. The process for preparing a resin molded article having a plated layer according to claim 17 , wherein the plated layer is a copper plated layer.

19. A process for manufacturing a part having an antenna for portable electronic devices, comprising the process for preparing a resin molded article having a plated layer according to claim 17 .

20. A laser direct structuring additive comprising a conductive oxide having a resistivity of 5×10 3 Ω·cm or less, which contains at least a metal of Group n, wherein n is an integer of 3 to 16, and a metal of Group n+1 of the periodic table, wherein an amount of one of the metal of Group n, wherein n is an integer of 3 to 16, and the metal of Group n+1 of the periodic table contained in the laser direct structuring additive is 15 mol % or less provided that the total amount of the metals is 100 mol %.
