Zusammenfassung:	Provided is an adhesive for an optical film, capable of improving durability and suppressing bending and dent damages under harsh environments (high temperature, high humidity, thermal shock) even when the adhesive is used for a single-sided protective polarizing plate, and achieving excellent rework properties (processability). The adhesive for the optical film includes: a polymer component (A) having a hydroxyl group; and a silane coupling agent (B) having a plurality of isocyanate groups, wherein the silane coupling agent (B) is a compound having an isocyanurate skeleton including a plurality of isocyanate groups having a specific structure. 편면 보호 편광판에 이용하였을 경우에도 가혹한 환경 하(고온, 고습, 열 충격)에 있어서의 내구성을 향상시키는 동시에 휨 및 타흔의 양쪽을 억제할 수 있고, 더욱이 리워크성(가공성)도 뛰어난 광학 필름용 점착제를 제공한다. 수산기를 갖는 중합체 성분(A)과 이소시아네이트기를 복수 개 갖는 실란 커플링제(B)를 포함하는 광학 필름용 점착제이며, 상기 실란 커플링제(B)가 특정한 구조의 이소시아네이트기를 복수 개 갖는 이소시아누레이트 골격을 갖는 화합물인 것을 특징으로 하는 광학 필름용 점착제.
