Abstract: A reflecting film has at least a transparent polymer film and a thin silver layer applied on the transparent polymer film to reflect light entered from a side of the transparent polymer film. The reflecting film retains a reflectance of at least 90% to visible light even after the reflector is exposed for 300 hours at a reflecting film temperature of 100.degree. C. and an exposure intensity of 500 mW/cm.sup.2 to artificial sunlight from which light of 390 nm and shorter in wavelength has been eliminated. For fabricating the reflecting film, a surface of the transparent polymer film is preferably treated with a metal-containing plasma, then the thin-silver layer is deposited on the treated surface. A reflector making use of the reflecting film is also disclosed.

Abstract: A laminate using a polymeric molded article as a substrate and having a light transparency, gas barrier properties and an excellent alkali resistance. The laminate is obtainable by carrying out a surface treatment to deposit an oxide of at least one metal selected from the metal elements of groups 2, 8, 9, 10 and 11 of the periodic table, and then forming a gas barrier layer such as oxides of silicon, nitrides of silicon and carbides of silicon on the treated surface. The gas barrier layer is not peeled off from the polymeric molded article even after being immersed in an alkali solution of pH 12 or more. The amount of the metal on the treated surface is preferably in the range of 5.times.10.sup.14 atoms/cm.sup.2 to 3.times.10.sup.16 atoms/cm.sup.2 in terms of the metal atoms per unit area. The practical performance of the laminate is not deteriorated during the patterning, by alkali etching, of a transparent conductive layer formed on the laminate.
