Summary:Provided is a laminate useful as a glass substitute material while having high hardness and excellent flexibility. The laminate has a hard coating layer on one side of a base film and a cured resin layer on the other side of the base film, cracks do not occur when wound around a cylinder with a diameter of 30 mm, the hardness when 500 nm indenter is pressed in by a nano indentation method is 0.5 to 1.5 GPa and/or the hardness at 500 mN load using an ultra-micro hardness tester is 0.29-1.10 GPa. 높은 경도와 우수한 가요성을 갖고, 유리 대체 재료로서 유용한 적층체를 제공한다. 기재 필름의 한쪽 면 상에 하드 코팅층을 갖고, 상기 기재 필름의 다른 쪽 면 상에 수지 경화층을 갖는 적층체이며, 직경 30mm의 원기둥에 감았을 때에 크랙이 발생하지 않는 것이고, 나노인덴테이션법에 의해 압자를 500nm 압입했을 때의 경도가 0.5 내지 1.5GPa이고/이거나 초미소 경도계를 사용한 500mN 하중에서의 경도가 0.29 내지 1.10GPa인 것을 특징으로 하는 적층체.
