<p>The invention provides monolayer films which not only have hydrophilicity and are excellent in such properties as antifogging properties, antifouling properties, antistatic properties and anti-condensation properties but also tend to exhibit excellent transparency even with a large film thickness and excellent scratch resistance, as well as stacks having the monolayer film. The monolayer film is obtained by preparing a mixture including a monomer composition and a solvent, the monomer composition including a specific monomer and a polyvalent monomer having two or more (meth)acryloyl groups and being free of sulfonic group, carboxyl group and phosphoric group in a specific molar ratio, the solvent having a specific solubility parameter Ã; applying the mixture onto a substrate and removing at least part of the solvent; and polymerizing the monomer composition to produce a monolayer film having at least one anionic hydrophilic group selected from a sulfonic group, a carboxyl group and a phosphoric group and a specific anion concentration ratio (Sa/Da) of the anion concentration (Sa) at the outer surface to the anion concentration (Da) at the middle point between the inner surface in contact with the substrate and the outer surface.</p> |
