<p>Provided is a vinylidene fluoride resin film that has good adhesiveness to a base material, achieves good dispersivity even when a pigment is contained in large amounts, and has excellent thermal stability during a forming process. To a resin component composed of a vinylidene fluoride resin and a methacrylic acid ester resin, a predetermined amount of a titanium oxide surface treated with alumina and silica and a predetermined amount of a fatty acid ester of polyethylene glycol and/or its derivative are added to prepare a vinylidene fluoride resin film. Alternatively, at least a front side layer and a back side layer have such a composition, the front side layer has a combination amount of the vinylidene fluoride resin and the methacrylic acid ester resin of 70 : 30 to 95 : 5 in terms of mass ratio, and the back side layer has a combination amount of the vinylidene fluoride resin and the methacrylic acid ester resin of 5 : 95 to 45 : 55 in terms of mass ratio. In each case, the total adhesion amount of alumina and silica is 5 to 11% by mass in the titanium oxide relative to the total mass of the titanium oxide.</p> |
