PROBLEM TO BE SOLVED: To obtain a fluororesin film coated steel sheet having excellent water resistance and moisture resistance. SOLUTION: In the fluororesin film coated steel sheet, a first adhesive layer, second adhesive layer made of plasticized polyvinyl chloride resin film having 5 wt.% or less of water absorbing properties when dipping in boiled water for 2 hours, and polyester resin, polyurethane resin or trivalent or more or polyhydric isocyanate and transparent or translucent ethylene-tetrafluoroethylene copolymer film are sequentially laminated. Accordingly, film release is prevented for a long period even in severe moisture atmosphere such as water section by a combination of specifying water absorbing ratio of the plasticized resin film and type of second adhesive. |
