  • Patent number: 4386175
    Abstract: This invention relates to a resin composition characterized in that a conventional chemical etching treatment is removed and instead of it a surface of the resin composition is plated with a metallic layer having a strong adhesive force, by means of a surface treatment by only a dry etching. Accordingly, the surface thereof can be directly treated with electroplating. Further, the use of chromic acid as a source of environmental pollution or other conventional addition agents for the surface treatment is completely eliminated.
