Abstract:
1. A plated-polyester article comprising a polyester article (A) and a plating layer (B) formed on the surface of the article, wherein (1) the polyester article (A) is irradiated with ionizing radiation to crosslink a polyester resin, (2) the arithmetic mean roughness Ra of the surface of the plating layer (B) is at most 1 μm, and (3) adhesion strength between the polyester article (A) and the plating layer (B) is at least 2 MPa, wherein the polyester article (A) is an article obtained by melt-molding a resin composition with an inorganic filler selected from the group consisting of calcium pyrophosphate, crushed silica and spherical silica having an average particle diameter of 1 to 10 μm dispersed in a proportion of 5 to 20 vol. % in a polyester resin crosslinkable by irradiation with ionizing radiation, and has been irradiated with ionizing radiation to crosslink the polyester resin, and further wherein the polyester article (A) has been etched with an aqueous solution of sodium hydroxide to form fine irregularities in the surface thereof.
