Objects of the present invention are to provide a composition which can easily give cured products enriched with hydrophilic groups at the surface, and a composition which can give cured products while ensuring that the surface is enriched with hydrophilic groups which are hardly concentrated at the surface by conventional methods; to provide cured products obtained from such compositions; to provide a composition which is suited for producing cured products having high and long-lasting hydrophilicity and also having high surface smoothness; and to provide a cured product obtained from the composition. A monolayer film is fabricated which includes a crosslinked resin obtained by polymerizing a composition including a compound (I) having at least one hydrophilic group selected from anionic hydrophilic groups, cationic hydrophilic groups and hydroxyl groups, and at least one functional group with a polymerizable carbon-carbon double bond (wherein the number of the functional groups with a polymerizable carbon-carbon double bond is one when the hydrophilic group is a hydroxyl-containing group); a compound (II) having two or more functional groups with a polymerizable carbon-carbon double bond (wherein the compound may have a hydroxyl group but is free from anionic hydrophilic groups and cationic hydrophilic groups); and at least one compound selected from a surfactant (III) having a hydrophilic moiety including an anionic hydrophilic group, a cationic hydrophilic group or two or more hydroxyl groups, and a hydrophobic moiety including an organic residue, and a compound (IV) having a siloxane bond and a molecular weight of 200 to 1,000,000 (wherein the surfactant (III) and the compound (IV) have no polymerizable carbon-carbon double bonds). The monolayer film has a gradient of hydrophilic group concentration (Sa/Da) of not less than 1.1 wherein Sa is the surface concentration of at least one type of hydrophilic groups selected from anionic hydrophilic groups, cationic hydrophilic groups and hydroxyl groups, and Da is the deep concentration of the hydrophilic groups at 1/2 of the thickness of the monolayer film.

The purpose of the present invention is to provide a modified acrylic resin cured product, particularly, a modified acrylic resin film, having excellent lubricity and excellent transparency, and a laminate including the modified acrylic resin film. The modified acrylic resin cured product (C) according to the present invention is obtained by treating the surface of a cured product (X) including an acrylic resin by using a compound (A) containing, in each molecule, one or more anionic hydrophilic groups forming an ion pair with an onium ion of an amino silicone, and one or more groups selected from the group consisting of a group containing a polymerizable carbon-carbon double bond, an amino group, a mercapto group and a hydroxy group.

In the present invention, there is provided a hydrophilic monolayer film that is excellent in antifogging properties, antifouling properties, the durability of antifogging properties and antifouling properties, and smoothness and that has an antireflective function or a surface structure that serves as a polarizer. There is also provided a method for easily producing such a monolayer film. The monolayer film that is to be produced has a surface structure with multiple protrusions and depressions. The distance between the peaks of adjoining protrusions among such multiple protrusions is in the range of 1 nm to 800 nm. The monolayer film is formed of a crosslinked resin produced by curing of a polymerizable composition that contains a compound having a specific hydrophilic group and a functional group with a polymerizable carbon-carbon double bond and a compound having two or more (meth)acryloyl groups. A gradient of the concentration of hydrophilic groups (Sa2/Da2) in the monolayer film is not less than 1.1 wherein Sa is the concentration of at least one type of hydrophilic groups selected from anionic hydrophilic groups, cationic hydrophilic groups, and a hydroxyl group at the top layer, and Da is the depth concentration of the hydrophilic groups at 1/2 of the thickness of the monolayer film.
