OPTICAL LAMINATE FILM

PROBLEM TO BE SOLVED: To provide an antireflection film having sufficient adhesiveness between a sol-gel layer and a hard coat layer without subjecting the hard coat layer to a surface treatment or the like.SOLUTION: An optical laminate film is provided, having an active energy ray-cured coating layer and a thermoset coating layer, layered on a transparent substrate film; and a composition for forming the coating layer is provided. The active energy ray-cured coating layer is a film A containing an active energy ray-curable resin and a photopolymerization initiator; and the thermoset coating layer is a film B containing silicon oxide. The composition for forming the film A and/or the film B satisfies two or more conditions in the following conditions: the film A contains an alkoxysilane and its hydrolysate having a photosetting reactive group in the molecule; the film A contains an active energy ray-curable resin having at least one reactive group selected from a hydroxyl group, an epoxy group and an isocyanate group in the molecule; and the film B contains an alkoxysilane and its hydrolysate having a photosetting reactive group in the molecule.
