Abstract

PURPOSE: To prevent deterioration of the reflectance of a reflective plate by applying a reflective layer on a prime coat and by coating the reflective layer with a protective layer of an alkali metal silicate.
CONSTITUTION: An ultraviolet curing resin paint is applied on one surface of a base plate 22 to form a prime coat 23. When ultraviolet rays are radiated onto the coated paint for several minutes the paint will be fully cured to form a very hard prime coat 23. On the smoothed surface of the base plate 22 with the prime coat 23 thereon is then coated a reflective layer 24. The reflective layer 24 is formed by application of a metal such as aluminum, chromium, nickel or silver. If use is made of aluminum, it will be deposited by vacuum deposition. On the reflective layer 24 is coated protective layer 25 of an amorphous film comprising an alkali metal silicate, part of which alkali metal silicate may have been modified by at least one of boric acid and phosphates.
