POLYESTER-BASED FILM AND ITS PRODUCTION

摘要

PROBLEM TO BE SOLVED: To obtain a high-performance polyester-based film in which various coating defects which occurs in coating process and provide a method for producing the film. SOLUTION: This method for producing a polyester-based film feathers applying an aqueous or water-disperse-based resin at <=50 deg. contact angle of coating solution under atmosphere having <=5,000/ft2 dust having >=2μm particle size and drying and stretching the resin. This film is produced by the above method.
