Abstract

An optical laminate comprising an adherend including a curable resin, and a barrier film laminated on at least one surface of the adherend, wherein the barrier film comprises, on an outermost surface facing the adherend, a primer layer formed by curing a primer composition containing a silane coupling agent having a reactive functional group capable of reacting with the curable resin, other than an alkoxysilane group and a silanol group, and assuming that a thickness of the primer layer is D, a total content of the reactive functional group and the reactive functional group that has reacted with the curable resin per 1 m×D of the primer layer is 1.5×10mol or higher and 3.5×10mol or lower.
