Minute-cellular polyester film provided with coating

A film is disclosed, which comprises an at least uniaxially stretched finely cellulated polyester film of a high surface roughness having an apparent specific gravity in the range of 0.4 to 1.3 and an opacifying power of not less than 0.2, and a coating applied to either or both of the opposite surf...

Zusammenfassung:	A film is disclosed, which comprises an at least uniaxially stretched finely cellulated polyester film of a high surface roughness having an apparent specific gravity in the range of 0.4 to 1.3 and an opacifying power of not less than 0.2, and a coating applied to either or both of the opposite surfaces of the polyester film. The coating applied to the minute-cellular polyester film serves the purpose of improving the adhesive property of the polyester film.
