Zusammenfassung:PURPOSE:To obtain a colored film having excellent weather resistance, decoration, contamination resistance, chemical resistance and adhesive properties by specifying vinylidene fluoride resin and methacrylic acid ester resin components, and coloring at least one of a surface layer, an intermediate layer and a rear layer with an organic pigment. CONSTITUTION:A composition containing 100-50 pts.wt. of vinylidene fluoride resin, 0-50 pts.wt. of methacrylic acid ester resin and 0-15 pts.wt. of ultraviolet ray absorbent as main ingredients is used as a surface layer. A composition containing 100-50 pts.wt. of methacrylic acid ester resin, 0-50 pts.wt. of vinylidene fluoride resin and 0.1-15 pts.wt. of ultraviolet ray absorbent as main ingredients is used as a rear layer, and at least one layer is covered with an organic pigment. Thus, it can be effectively used for a sheath utility which is particularly severely affected by the influence of direct sunshine with excellent decoration, chemical resistance, excellent long term weather resistance of the vinylidene fluoride resin and no decrease in adhesive properties to a base material for a long period.
