The invention provides a cured product (for example, a film including the cured product) which has an excellent balance between hydrophilicity and abrasion resistance, can retain high hydrophilicity even when washed with water, and can remain hydrophilic and resistant to the attachment of (or can be easily cleaned of) contaminants even when subjected to long storage or heating, and a composition which can give such cured products. A cured product is obtained by curing a composition which includes a copolymer (i) including structural units represented by specific chemical formulae, and an amino resin (ii).

摘要:
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.

The invention provides monolayer films excellent in hydrophilicity and transparency which include a crosslinked resin having a surface enriched with hydrophilic groups, and materials which exhibit excellent properties such as hydrophilicity, antifogging properties and antifouling properties by virtue of having the above monolayer films. A monolayer film is fabricated which includes a crosslinked resin obtained by polymerizing a composition including a compound (I) having an anionic hydrophilic group and a functional group with a polymerizable carbon-carbon double bond, and a compound (II) having three or more hydroxyl groups and three or more functional groups with a polymerizable carbon-carbon double bond, the monolayer film having a gradient (Sa/Da) of not less than 1.1 wherein Sa is the surface concentration of the anionic hydrophilic groups in the monolayer film, and Da is the deep concentration of the hydrophilic groups at 1/2 of the thickness of the monolayer film.
