  • Patent number: 4348463
    Abstract: The reflector of the present invention is the one in which on a substrate are successively arranged a resin layer, preferably, a resin layer having a molar percentage of an aryl group/(alkyl group plus aryl group) is 65-100%, a vacuum deposited layer of a light reflective metal and a light transmissible crystalline ceramic layer in this order. Pinholes or non-smoothness on the substrate is eliminated by disposing the resin layer on the substrate, and a vacuum deposited layer of a light reflective metal having a smooth surface is easily obtained. And on the surface thereof is disposed a vacuum coated layer of the light transmittable crystalline ceramic, and hence, without taking the reflector out of a vacuum depositor, it can be vacuum deposited continuously and its manufacture is very easy.
