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 ½ of the thickness of the monolayer film.
