1. In a laminated film having:
- (A) an organic polymer film,(B) a thin metal layer having a thickness of 30 to 500 A laminated on at least one surface of said organic polymer film,(C) the improvement which comprises coating said thin metal layer with a transparent thin layer containing metal compounds and having a thickness of 0.02 to 0.3μ
laminated on said thin metal layer (B),wherein at least 60 wt. % of said transparent thin layer (C) comprises zirconium, silicon and oxygen, and at least 60 molar % of metal elements in the above transparent thin layer (C) comprises zirconium and silicon in the range of molar ratio Zr/Si of 80/20 to 20/80, whereby said film shows significant increases in resistance against abrasion, light, weather, and heat.

10. In a laminated film having:
-
(A) an organic polymer film, (B) a thin metal layer having a thickness of 30 to 500 A laminated on at least one surface of said organic polymer film, (C) the improvement which comprises coating said thin metal layer with a transparent thin layer containing metal compounds and having a thickness of 0.02 to 0.3μ
laminated on said thin metal layer (B),wherein said transparent thin layer (C) is formed by applying a mixture of at least one of at least one of zirconium compounds of the general formula;
