Abstract

PURPOSE:To provide a reflector with excellent durability. CONSTITUTION:By laminating a metallic thin film containing silver on the one surface of a flexible base plate having transmittance of 10% or less in a wave length of 380-100nm, a reflector is improved in its durability against light, heat or the like without significantly lowering the reflectance of visible rays. In this way, the deterioration of the reflector due to light or heat is restrained and thereby the durability and practicability of the reflector is improved.

However, a coating film made of an aluminum vapor deposition product, a stainless steel plate, a resin or the like had a low reflectance and was completely inadequate. In addition, a light reflector with a silver thin film layer formed on a general-purpose plastic film has a high reflectance when manufactured, but due to environmental factors such as heat and light, the reflectance of the reflector is remarkably reduced by ultraviolet rays. However, there is a technical problem that the function of the backlight as a reflector is not satisfied.
