description	An embodiment of the present invention provides an optical film manufactured from a polymerizable composition containing: a diamine monomer; and at least one of a dianhydride compound and a dicarbonyl compound, wherein the optical film has a yellowness index change (△Y.I.) of 1 or less at a thickness of 50 μm. In the optical film, the yellowness index change is calculated by equation 1: [Equation 1] △Y.I. = │Y.I.(300℃) - Y.I.(270℃)│, wherein, the Y.I. (300℃) is the yellowness index (Y.I.) of the optical film as measured after cooling to room temperature following heat treatment at 300℃ for 10 minutes, and the Y.I. (270℃) is the yellowness index (Y.I.) of the optical film as measured after cooling to room temperature following heat treatment at 270℃ for 10 minutes. Un mode de réalisation de la présente invention concerne un film optique fabriqué à partir d'une composition polymérisable contenant : un monomère diamine ; et au moins un composé parmi un composé dianhydride et un composé dicarbonyle, le film optique présentant un changement d'indice de jaunissement (△Y.I.) inférieur ou égal à 1 à une épaisseur de 50 µm. Dans le film optique, le changement d'indice de jaunissement est calculé par l'équation 1 : [Équation 1] △YI = │Y.I.(300 ℃) - Y.I.(270 ℃)│, dans laquelle Y.I.(300 °C) est l'indice de jaunissement (Y.I.) du film optique tel que mesuré après refroidissement à température ambiante après traitement thermique à 300 °C pendant 10 minutes et Y.I.(270 °C) est l'indice de jaunissement (Y.I.) du film optique tel que mesuré après refroidissement à température ambiante après traitement thermique à 270 °C pendant 10 minutes. 본 발명의 일 실시예는, 디아민 모노머; 및 디안하이드라이드 화합물 및 디카르보닐 화합물 중 적어도 하나;를 포함하는 중합성 조성물로부터 제조되며, 50㎛ 두께를 기준으로, 황색도 변화(△Y.I.)가 1 이하인 광학 필름을 제공한다. 여기서 황색도 변화는 하기 식 1로부터 계산되며, [식 1] △Y.I. = │Y.I.(300℃) - Y.I.(270℃)│ 상기 식 1에서 상기 Y.I.(300℃)은 300℃에서 10분간 열처리 후 상온으로 냉각한 뒤 측정된 상기 광학 필름의 황색도(Y.I.)이며, 상기 Y.I.(270℃)은 270℃에서 10분간 열처리 후 상온으로 냉각한 뒤 측정된 상기 광학 필름의 황색도(Y.I.)이다.
