PURPOSE: Partially metal-plated products of synthetic resin that is produced by etching, neutralizing and electrically plating two-colored products composed of a thermoplastic resin composition containing a specific carbon block and a thermolastic resin. n CONSTITUTION: Two-colored molded products are formed from (A) a thermoplastic resin composition with volume specific resistivity of 10 8 ohm or less that is composed of (a) 100 parts by wt of one or more thermoplastic resins such as polypropylene or vinyl chloride resins and (b) 3W100 parts of carbon black with 200ml/ 100g or more oil absorption and 500m 2 /g surface area and (B) at least one thermoplastic resin. The products are etched, neutralized and metal-plated directly on the part of (A). n COPYRIGHT: (C)1979,JPO&Japio |
