Document Type and Number:
WIPO Patent Application WO/2018/038271
Kind Code:
The main purpose of the present invention is to impart a greater antifog property and a greater antireflective function to a hydrophilic material that was previously presented by the present inventors and comprises a cross-linked resin wherein hydrophilic groups are segregated to a surface thereof. A laminate according to the present invention is provided with a water absorption layer (B), an antireflective function imparting layer (C), and a hydrophilic layer (A) in this order on a substrate, wherein the hydrophilic layer (A) comprises a cross-linked resin having an anionic, cationic, or nonionic hydrophilic group, the gradient (hydrophilic group strength at a surface of the hydrophilic layer (A)/hydrophilic group strength at a point at 1/2 the thickness of the hydrophilic layer (A)) of the hydrophilic groups in the hydrophilic layer (A) is 1.1 or greater, the water absorption layer (B) comprises a cross-linked resin with a water absorption rate in the range of 5-500wt% per unit mass (g), and the refractive index of a layer that makes up the layer (C) satisfies a particular condition.
