Abstract

PURPOSE: To form a fog resistant film of high surface hardness and fog resistant characteristic by impregnating a hydrophilic or hydrophobic resin in a porous film formed through anodic oxidation of the metallic thin film on a substrate.
CONSTITUTION: A transparent conductive film 4 such as "NESA film" is formed on a substrate 3 of glass etc. and a metal thin film 5 of Al etc. is formed thereon. This is immersed in a sulfuric acid bath 6, and a power source 8 is connected between the conductive film 4 and an electrode 7 of platinum etc. in the bath 6, thence the thin film 5 is anodized. Then, the thin film 5 is made porous uniformly over the entire area. The fog resistant film obtained by impregnating a hydrophilic or hydrophobic resin in this porous film retains the fog resistant resin in its oxide film pores and therefore it has high hardness and retentivity of for resistance.
