    摘要： It is a main object of the present invention to impart higher antifogging properties to the hydrophilic material formed of a crosslinked resin, having a surface enriched with hydrophilic groups, previously proposed by the inventors. The laminate of the present invention includes a water absorbing layer (B) and a hydrophilic layer (A) provided in this order on a substrate, wherein the hydrophilic layer (A) is formed of a crosslinked resin having an anionic, cationic or nonionic hydrophilic group, and has a gradient of hydrophilic groups (intensity of hydrophilic group on surface of the hydrophilic layer (A)/intensity of hydrophilic group at ½ of thickness of the hydrophilic layer (A)) of not less than 1.1; and the water absorbing layer (B) is formed of a crosslinked resin having a water absorption rate per unit mass (g) of in the range of 5 to 500 wt %.

    摘要： The present invention provides: a composition including a polymer (i) which has a —SO3M group and an epoxy group, wherein M represents a hydrogen atom, an alkali metal, an alkaline earth metal or an ammonium ion, and a silane compound (ii) which has at least two hydroxy group(s), alkoxy group(s) or halogen atom(s) that are each bound to a silane atom; and a hydrophilic film obtained by curing the composition. The hydrophilic film of the present invention is excellent in its hydrophilicity, durability, abrasion resistance and weather resistance and has high antifogging, antifouling, antistatic and quick-drying (water evaporation) properties. Therefore, a variety of laminates in which the hydrophilic film of the present invention is laminated on a substrate can also be provided.
