The objective of the present invention is to provide a coating composition that shows the effect of implementing an excellent elongation rate while remaining constant over a certain level of surface properties, and a laminate comprising the same. To this end, a laminate according to the present invention comprises: a base material layer; and a coating layer positioned on one surface of the base material layer, wherein the coating layer is a cured layer of a coating composition including a monomer having a nitrogen-containing functional group and a urethane acrylate-based oligomer, and it may exhibit an elongation rate of 40% or more. 본 발명에 따른 적층체는 기재층 및 기재층의 일면 상에 위치하는 코팅층을 포함하며, 상기 코팅층은 질소 함유 관능기를 갖는 모노머 및 우레탄 아크릴레이트계 올리고머 성분을 포함하는 코팅 조성물의 경화층으로, 40% 이상의 신장율을 나타내는 것일 수 있다.
