Title (EN) POLYPROPYLENE RESIN FOR PROTECTIVE FILM AND PROTECTIVE FILM
(FR) RÉSINE POLYPROPYLÈNE POUR FILM PROTECTEUR ET FILM PROTECTEUR
(KO) 보호필름용 폴리프로필렌 수지 및 보호필름
Abstract: front page image
(EN)A polypropylene resin for a protective film according to the present invention has an ethylene content of 10-20 wt% in the polypropylene resin, wherein the ratio (a/b) of the ethylene content to an ethylene content in a solvent extract (b) is 3-4. The polypropylene resin has excellent release ability from an adhesive layer and exhibits a superior effect in reducing the occurrence of fish-eye defects. In addition, the protective film manufactured using the polypropylene resin can be applied for a protective film having fine surface unevenness for backlight unit optical sheets, such as a prism sheet, a micro-lens film, a patterned light guiding plate, and a diffusing plate, due to its excellent release ability and the reduction in the occurrence of fish-eye defects.
(FR)La résine polypropylène pour film protecteur selon la présente invention a une teneur en éthylène de 10 à 20 % en poids dans la résine polypropylène, le rapport (a/b) de la teneur en éthylène à une teneur en éthylène dans un extrait au solvant (b) est de 3-4. La résine polypropylène a une excellente facilité de séparation d'une couche adhésive et fait preuve d'un effet supérieur en termes de réduction de l'occurrence de défauts de type "fish-eye". De plus, le film protecteur fabriqué à l'aide de la résine polypropylène selon l'invention peut être appliqué à titre de film protecteur ayant une fine irrégularité de surface à des feuilles optiques d'unités de rétro-éclairage, telles qu'une feuille prismatique, à un film pour micro-lentille, à une plaque guide-lumière structurée, et à une plaque de diffusion, en raison de son excellente facilité de séparation et réduction de l'occurrence de défauts de type "fish-eye".
(KO)본 발명에 따른 보호필름용 폴리프로필렌 수지는 폴리프로필렌 수지 내 에틸렌의 함량은 10~20중량%이며, 상기 에틸렌의 함량과 b) 용제추출물 내 에틸렌 함량의 비율(a/b)이 3~4인 것을 특징으로 하여, 점착층과의 이형성이 우수하고 피쉬아이의 발생을 줄이는데 탁월한 효과를 나타낸다. 또한, 상기 폴리프로필렌 수지를 이용하여 제조된 보호필름은 점착층과의 이형성 우수 및 피쉬아이의 발생 저하로 인하여 프리즘시트, 마이크로렌즈 필름, 패턴 도광판 및 확산판 등의 미세한 표면요철을 갖는 백라이트 유닛 광학시트의 보호필름으로 적용이 가능하다.
