摘要： Provided is a laminate that may exhibit thermally stable hydrophilicity, and a coating composition that may be used for such a laminate. A laminate according to one embodiment of the present disclosure includes: a substrate; a first layer disposed on at least one surface of the substrate, the first layer including a binder and an inorganic nanoparticle; and a hydrophilic second layer disposed on the first layer, the binder containing a cured product of a binder precursor containing 30 mass % or greater of a tri- or higher functional (meth)acrylate monomer relative to a total amount of the binder, and the inorganic nanoparticle having a (meth)acryloyl group.
