감압 접착제와 자외광-흡수 올리고머의 블렌드를 포함하는 조성물. 올리고머는 펜던트 자외선 흡수 기를 갖는 제1 2가 단위 및 하기 화학식에 의해 나타내어지는 제2 2가 단위를 갖는다: [화학식 I]상기 식에서, R은 수소 또는 메틸이고, R는 4 내지 20개의 탄소 원자를 갖는 알킬이다. 조성물을 포함하는 물품이 개시된다. 예를 들어, 배리어 필름 및 조성물을 포함하는 조립체가 또한 개시된다. A composition that includes a blend of a pressure sensitive adhesive and an ultraviolet light-absorbing oligomer. The oligomer has a first divalent unit having a pendent ultraviolet absorbing group and a second divalent unit represented by formula in which R1 is hydrogen or methyl, and R2 is alkyl having from 4 to 20 carbon atom. Articles including the composition are disclosed. For example, an assembly including a barrier film and the composition is also disclosed.
