ABSTRACT:
A multi-layer coating reflector consisting of 3 or 4 layers of the present invention, which comprises a light reflective metallic vacuum-deposited layer disposed on a substrate which may, or may not, have a resin layer thereon and a light transmittable inorganic or light transmittable resin layer which may, or may not, be further disposed on the surface of that, use for one or both of the resin layers high aryl silicone resin in which the mole percentage of aryl/alkyl+aryl is 65-100%.
With the use of such high aryl silicone resin, when said resin is a protective layer, the reflector has excellent resistance to light, weathering, water, humidity, chemicals and bending and when it is on the substrate, the light reflective metal has excellent reflection properties and obtains bright reflected images, high precision light collection and distribution properties.
