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 CSR particles and an acrylic resin represented by chemical formula (1); having peelability of 20gf/2inch or lower when peeled at a peeling speed of 0.5mpm; and having tear strength of 6gf or higher. The present invention has excellent peelability and thus enables reduction of exterior stain due to non-uniform thickness, and has high tear strength and thus has improved brittleness.
(FR) La présente invention concerne un film acrylique caractérisé en ce qu'il est formé à partir d'une solution principale de dopant comprenant des particules de CSR et d'une résine acrylique représentée par la formule chimique (1); en ce qu'il présente une aptitude au pelage de 20 gf/2 pouces ou moins lorsqu'il est pelé à une vitesse de pelage de 0,5 mpm; et en ce qu'il présente une résistance à la déchirure supérieure ou égale à 6 gf. La présente invention présente une excellente aptitude au pelage et permet ainsi une réduction de la souillure extérieure due à une épaisseur non uniforme et présente une résistance à la déchirure élevée et présente ainsi une fragilité améliorée.
(KO) 본 발명은 화학식 1로 표시되는 아크릴 수지 및 CSR 입자를 포함하는 주 도프액으로부터 형성되고, 0.5mpm의 박리 속도로 박리시 박리력이 20gf/2inch 이하이며, 인열강도가 6gf 이상인 것을 특징으로 하는 아크릴 필름으로서, 박리력이 우수하여 두께 불균일에 의한 외관 얼룩이 개선되었고, 인열강도가 높아 취성이 좋다.
