POLYESTER FILM AND HARD COATING FILM

摘要

PROBLEM TO BE SOLVED: To provide a hard coating film free from heat curling arising in thermal processing, improved in attaching easiness of the film and reducing a production loss in applying the hard coating film. SOLUTION: This hard coating film having suppressed heat curling is achieved by a polyester film having 0.2-0.8% heat shrinkage percentage in a wide direction when heat-treated at 150 deg.C for 30 min.
