Zusammenfassung:	The present invention relates to a light guide film (100) comprising: a base layer (101); and an optical pattern layer (102) on at least one surface of the base layer (101), wherein the optical pattern layer (102) comprises a cured product of a composition containing at least one (meth)acrylic copolymer, at least one (meth)acrylic ester monomer, and at least one aziridine cross-linker, so that the light guide film (100) has excellent adhesion even without a separate adhesion promoting layer, leading to an improvement in durability, and thus can achieve thinning of a backlight unit. La présente invention concerne un film guide de lumière (100) comprenant : une couche de base (101) ; et une couche de motif optique (102) sur au moins une surface de la couche de base (101), la couche de motif optique (102) comprenant un produit durci d'une composition contenant au moins un copolymère (méth)acrylique, au moins un monomère d'ester (méth)acrylique, et au moins un agent de réticulation aziridine, de manière que le film guide de lumière (100) dispose d'une excellente adhérence même sans couche favorisant l'adhérence distincte, ce qui permet une amélioration de la durabilité et d'obtenir ainsi un amincissement d'une unité de rétroéclairage. 본 발명은 기재층(101); 상기 기재층(101)의 적어도 일 면 상에 광학패턴층(102);을 포함하고, 상기 광학패턴층(102)은 각각 1종 이상의 (메트)아크릴계 공중합체, (메트)아크릴계 에스테르 모노머 및 아지리딘 가교제를 함유하는 조성물의 경화물을 포함함으로써, 별도의 밀착력 증진층 없이도 밀착성이 우수하여 내구성이 향상되고, 그로 인해 백라이트 유닛을 박형화할 수 있는 도광필름(100)에 관한 것이다.
