A single layer film containing at least one anionic hydrophilic group selected from a sulfonic acid group, a carboxyl group and a phosphate group, wherein an anion concentration ratio (Sa/Da) of an anion concentration at a surface (Sa) to an anion concentration at a deep part (Da) is 1.1 or more. The single layer film is a copolymer prepared by polymerizing a composition containing a compound (I) represented by the general formula (1) ([X]s[M1]1[M2]m (1)) and a compound (II) having two or more (meth)acryloyl groups in a molecule at a molar ratio of 15:1 to 1: 30 and having a water contact angle of 30° or less. Such a single layer film has high hydrophilicity and surface hardness and is excellent in antifogging property, antifouling property and antistatic property, thus is useful as an antifogging material, an antifouling material, an antistatic material and a multilayer body.
一种单层薄膜,含有至少一个选自磺酸基、羧基和磷酸基的阴离子亲水基团,其中表层阴离子浓度(Sa)与深层阴离子浓度(Da)之比(Sa/Da)为 1.1 或以上。单层膜是一种共聚物,它是通过聚合含有通式(1)([X]s[M1]1[M2]m (1))表示的化合物(I)和分子中含有两个或两个以上(甲基)丙烯酰基的化合物(II)的组合物制备而成,摩尔比为 15:1 至 1:30,水接触角为 30°或更小。这种单层薄膜具有高亲水性和表面硬度,防雾性能、防污性能和抗静电性能优异,因此可用作防雾材料、防污材料、抗静电材料和多层体。
