Which has hydrophilicity and is excellent in antifogging property, antifouling property, antistatic property, dew condensation preventing property, and the like, and which has excellent transparency even when the film thickness is increased and tends to have excellent scratch resistance, and a laminate having the above- to provide. A monomer composition containing a specific monomer and a polyvalent monomer having at least two (meth) acryloyl groups and no sulfonic acid group, carboxyl group and phosphoric acid group in a specific molar ratio, and a solvent having a solubility parameter? At least one anionic hydrophilic group selected from a sulfonic acid group, a carboxyl group and a phosphoric acid group by polymerizing the monomer composition after preparing a mixture, applying the mixture to a substrate, removing at least part of the solvent, and And the anion concentration ratio Sa / Da of the anion concentration Sa at the surface and the anion concentration Da at the midpoint between the inner surface and the outer surface in contact with the substrate is within a specific range. |
