PROBLEM TO BE SOLVED: To provide a laminate using an aqueous resin composition as a primer enhancing adhesion between a base material and a cured coating film of an active energy ray-curable composition even in the case where the base material is a difficult-to-adhere base material such as a polyester film and to provide an optical film.SOLUTION: The laminate is used, which has a primer layer formed on the surface of a base material by using an aqueous resin composition containing (A) an aqueous urethane resin having a sulfonic acid group and (B) silica and has a cured coating film formed by using an active energy ray-curable composition on the surface of the primer layer.SELECTED DRAWING: None |
