BIAXIALLY ORIENTED POLYESTER FILM

摘要

PURPOSE:To obtain the title film having a flat and uniform surface and excellent traveling properties and abrasion resistance by adding thereto a specified amount of CaCO3 particles which have a specified particle diameter and are surface-coated with an organic crosslinked polymer. CONSTITUTION:This film contains 0.01-4wt.% CaCO3 particles which have a mean particle diameter of 0.05-3mum and are surface-coated with an organic crosslinkd polymer (e.g. acrylic acid/methyl methacrylate/ethylene glycol dimethacrylate/divinylbenzene copolymer).
