Abstract:
1. A radio wave transmitting decorative member comprising: a substrate which is a shaped article formed of an organic material; and a light reflecting layer provided on top of the substrate and formed of an alloy composed of a metal element and either silicon element or germanium element, wherein a ratio of the metal within the alloy is within a range from 0.1 to 60 volume %, based on the volume of the alloy, the light reflecting layer is a continuous layer comprising a homogenous amorphous structure in which no gaps are present where the alloy is absent, and the organic material is at least one member selected from the group consisting of polyolefin, cyclic polyolefin, modified polyolefin, polyvinyl chloride, polyvinylidene chloride, polystyrene, polyamide, polyimide, polyamideimide, polycarbonate, poly-(4-methylpentene-1), an ionomer, an acrylic resin, polymethyl methacrylate, an acrylonitrile-butadiene-styrene copolymer, an acrylonitrile-styrene copolymer, a butadiene-styrene copolymer, polyoxymethylene, polyvinyl alcohol, an ethylene-vinyl alcohol copolymer, polyester, polyether, polyether ketone, polyether ether ketone, polyether imide, polyacetal, polyphenylene oxide, modified polyphenylene oxide, polysulfone, polyether sulfone, polyphenylene sulfide, polyallylate, aromatic polyester, polytetrafluoroethylene, polyvinylidene fluoride, a styrene-based elastomer, a polyolefin-based elastomer, a polyvinyl chloride-based elastomer, a polyurethane-based elastomer, a polyester-based elastomer, a polyamide-based elastomer, a polybutadiene-based elastomer, a trans-polyisoprene-based elastomer, a fluororubber-based elastomer, a chlorinated polyethylene-based elastomer, an epoxy resin, a phenolic resin, a urea resin, a melamine resin, unsaturated polyester, a silicone-based resin, a urethane-based resin, a polyparaxylylene resin, natural rubber, polybutadiene rubber, polyisoprene rubber, acrylonitrile-butadiene copolymer rubber, styrene-butadiene copolymer rubber, styrene-isoprene copolymer rubber, styrene-butadiene-isoprene copolymer rubber, a hydrogenated product of diene-based rubber, saturated polyolefin rubber, an ethylene-propylene-diene copolymer, an a-olefin-diene copolymer, urethane rubber, silicone rubber, polyether-based rubber, and acrylic rubber.
