surface roughening of resin molded articles for metallizing.

摘要

A method for roughening the surface of a resin molded article to make it susceptible to metallizing is disclosed, comprising contacting a resin molded article at least the surface of which to be roughened mainly comprises a block copolymer comprising 100 parts by weight of a polyphenylene sulfide resin and from 30 to 100 parts by weight of a polyphenylene sulfide ketone resin with a solvent capable of dissolving a polyphenylene sulfide resin more than a polyphenylene sulfide ketone resin.
