Title (EN) POLYAMIDE PRECURSOR SOLUTION AND METHOD FOR PRODUCING SAME
(FR) SOLUTION DE PRÉCURSEUR DE POLYAMIDE ET PROCÉDÉ POUR SA PRODUCTION
(KO) 폴리이미드 전구체 용액 및 이의 제조방법
Abstract:
(EN) The present invention provides a polyamide film which, by having a fluorine structure adopted into a rigid polyamide chain structure, exhibits not only superb heat resistance but also enhanced optical properties. Additionally, the polyamide according to the present invention, by having the particular structure, exhibits excellent transparency, heat-resistance, mechanical strength and flexibility, and thus can be utilized in a variety of functions such as an element substrate, display cover substrate, optical film, integrated circuit (IC) package, adhesive film, multi-layered flexible printed circuit (FPC), tape, touch panel, and protective film for optical disks.
(FR) La présente invention concerne un film de polyamide qui, par le fait de présenter une structure de fluor adoptée dans une structure de chaîne de polyamide rigide, présente non seulement une excellente résistance à la chaleur mais également des propriétés optiques améliorées. De plus, le polyamide selon la présente invention, grâce à la structure particulière, présente une excellente transparence, une excellente résistance à la chaleur, une excellente résistance mécanique et une excellente flexibilité et peut ainsi être utilisé dans un certain nombre de fonctions telles qu'un substrat d'élément, un substrat de couvercle d'affichage, un film optique, un boîtier de circuit intégré (CI), un film adhésif, un circuit imprimé (FPC) souple multicouche, une bande, un écran tactile et un film protecteur pour disques optiques.
(KO) 본 발명은, 강직한 폴리이미드 사슬구조에 플루오렌 구조를 도입함으로써 우수한 내열성을 나타낼 뿐만 아니라, 광학적 특성이 동시에 향상된 폴리이미드 필름을 제공한다. 또한, 본 발명에 따른 폴리이미드는 특정한 구조를 포함함으로써, 투명성, 내열성, 기계적 강도 및 유연성이 우수하여, 소자용 기판, 디스플레이이용 커버기판, 광학필름, IC(integrated circuit) 패키지, 전착필름(adhesive film), 다층 FPC(flexible printed circuit), 테이프, 터치패널, 광디스크용 보호필름 등과 같은 다양한 분야에 사용될 수 있다.
