Abstract

본 발명은 폴리에스테르 수지의 적어도 한면에 유리전이 온도가 35~65℃인 아크릴 수지 50~70wt%, 분자 구조중에 아미노기를 갖는 하기 일반식(I)의 수분산성 오르가노폴리실록산 25~50wt%, 고급 지방산 왁스 1~5wt%및 불활성 무기미립자 1~5wt%를 혼합한 조성물을 건조피막의 두께가 100~10, 000A이 되도록 도포하고, 도포면의 표면장력이 35dyne/cm 이하인 층을 형성시킴을 특징으로 하는 슬립성과 이형성이 우수한 이축연신 폴리에스테르 필름의 제조방법에 관한 것이다.The present invention is 50 to 70wt% of acrylic resin having a glass transition temperature of 35 to 65 ° C on at least one side of the polyester resin, 25 to 50wt% of water dispersible organopolysiloxane of the following general formula (I) having an amino group in the molecular structure, 1-5 wt% of fatty acid wax and 1-5 wt% of inert inorganic fine particles are applied to a dry film having a thickness of 100-100,000 A, and a layer having a surface tension of 35 dyne / cm or less is formed. It is related with the manufacturing method of the biaxially-stretched polyester film excellent in the slip property and mold release property.

여기에서, R'은 히드록시기, 메틸기 또는 에틸기이며, R은 탄소수 0~10의 탄화수소에 NH또는가 결합된 것이고, m은 5~1000의 정수이며, n은 100~20000의 정수이고이다.Here, R 'is a hydroxy group, a methyl group or an ethyl group, and R is NH or a hydrocarbon having 0 to 10 carbon atoms. Are combined, m is an integer from 5 to 1000, n is an integer from 100 to 20000 to be.
