Abstract
Provided is a moisture absorption film layered product that can be photocured by using ultraviolet ray, which can achieve curing in a short time, and that has both excellent defogging properties and abrasion resistance. A moisture absorption film layered product including a moisture absorption film formed on a surface of a substrate, wherein the moisture absorption film is formed by curing a photocurable resin composition containing a siloxane resin (A) having a (meth)acryloyl group, three particular (meth)acrylate monomers (B), (C), and (D), and a photo-initiator as essential components, a blending proportion of (A):(B):(C):(D) is 0.1 to 5:35 to 55:0.5 to 10:40 to 60, (B) is a bifunctional monomer having a hydroxy group, (C) is a monofunctional monomer having an ethylene glycol chain, and (D) is a monofunctional monomer having a hydroxy group.
