摘要：

PROBLEM TO BE SOLVED: To provide a fluororesin film which is excellent in clarity and in intercepting ultraviolet rays with wavelengths of 360 nm or shorter. SOLUTION: This film is based on a fluororesin (e.g. an ethylene- tetrafluoroethylene copolymer) and contains composite particles dispersed therein. The composite particles have particle sizes of 1-30μm and are formed by agglomerating zinc oxide particles prepd. by coating 100 pts.wt. zinc oxide with 20-200 pts.wt. amorphous silica. Pref., the surfaces of the composite particles are hydrophobized with an organosilicon compd.
