A process for producing an electrolessly plated molded article, which includes molding a resin composition made of a thermoplastic resin having a specific Izod impact strength and a Rockwell surface hardness and an inorganic filler, then treating the surface of the molded article with air blast using an abrasive having a sharp granular shape, and then conducting catalyst coating, activation treatment and electroless plating. It has been possible to apply the electroless plating with a high adhesion strength to the molded article of the thermoplastic resin composition without conducting the chemical etching treatment.

Method of producing the plated molded articles by non-electrode plating, and the resin compositions for that use

A plastic optical transmittable fiber having improved optical transmission loss and flexibility and good heat resistance. The fiber comprises a cladding of a copolymer comprising 70 to 99.5 mole % of 4-methyl pentene-1 units and 30 to 0.5 mole % of units of an .alpha.-olefin of 2-24 carbon atoms, the refractive index of the core being higher than that of the cladding by at least 0.01.
