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. And yet combination of the abovementioned smooth metallic reflecting surface with properties of the crystalline ceramic having very little light refraction or absorption, make it undergo little change of total reflectivity, regular reflectivity and refractivity, resulting in a very clear reflected image or the one having a high precision light collective and light distributing properties. Further, since the outermost layer is a light transmittable crystalline ceramic vacuum deposited layer, the reflector has the properties that there is little loss of transparency or coloring degradation with the time and thermal conductivity is great; thus with the use as an illumination reflector, temperature rise is small and it is heat-, light-, weather- and solvent-resistant.
