Patent ID: 8895140

Claim:
A vinylidene fluoride resin film comprising: a vinylidene fluoride resin; a methacrylic acid ester resin; a titanium oxide surface treated with alumina and silica; and a fatty acid ester of polyethylene glycol and/or a derivative thereof; the titanium oxide having a total adhesion amount of alumina and silica of 5 to 11% by mass and having a particle diameter of 0.05 to 2.0 μm in terms of average particle diameter, inclusive of adhered silica and alumina, determined by precipitation, and wherein a color difference ΔE* ab of the resin film heated under a condition of 265° C. for 30 minutes is 2.5 to 4.3, and a color difference ΔE* ab of the resin film heated under a condition of 265° C. for 60 minutes is 3.3 to 6.5.
