Title (EN) ACRYLIC FILM
(FR) FILM ACRYLIQUE
(KO) 아크릴 필름
Abstract:
(EN) The present invention relates to an acrylic film characterized by being formed from a main dope solution comprising poly(methyl methacrylate) (PMMA) particles and an acrylic resin represented by chemical formula (1), and having a dynamic friction coefficient of 0.7 or lower. The present invention enables improved roll winding quality and quality maintenance over time.
(FR) La présente invention concerne un film acrylique caractérisé en ce qu'il est formé à partir d'une solution de dopage principale comprenant des particules de poly(méthacrylate de méthyle) (PMMA) et une résine acrylique représentée par la formule chimique (1), et ayant un coefficient de frottement dynamique de 0,7 ou moins. La présente invention permet d'améliorer la qualité d'enroulement sur rouleau et de maintenir la qualité dans le temps.
(KO) 본 발명은 화학식 1로 표시되는 아크릴 수지 및 폴리메틸메트아크릴레이트{PMMA; Poly(methyl methacrylate)} 재질의 입자를 포함하는 주 도프액으로부터 형성되며, 동마찰계수가 0.7 이하인 것을 특징으로 하는 아크릴 필름으로서, 롤(roll) 권취 품질이 좋아지고, 경시에 따른 품질 유지가 가능하다.
