PURPOSE: To obtain a fiber or film having color-anisotropy and high durability by forming a metallic reflection film having a specific thickness on a fiber and/or fiber structure or a film, applying a transparent film having a specific thickness to the surface of the reflection film and applying a resin layer to the transparent film.

CONSTITUTION: A reflection film consisting of a mixture of aluminum and aluminum oxide and having a film thickness of 100-2,000 in terms of metallic film is formed on the surface of a fiber such as natural fiber and synthetic fiber, a fiber structure such as knit, woven or nonwoven fabric or a film. A transparent film consisting of tin oxide or a mixture of tin oxide and tin and having a film thickness of 100-5,000 is formed on the reflection film e.g. by vacuum evaporation and the product is coated with a protection resin layer preferably composed mainly of ethyl acrylate and/or butyl acrylate to obtain the objective color-anisotropic fiber and/or fiber structure or film having excellent durability such as washing resistance and abrasion resistance.
