[Problem]
To provide hydrophilic modified acrylic resin films which exhibit excellent antifogging properties and antifouling properties and high transparency.
[Solution]
A modified acrylic resin film of the invention is obtained by treating a surface of an acrylic resin film having anionic hydrophilic groups with a compound (A), the acrylic resin film being such that the concentration of the anionic hydrophilic groups on the surface is higher than the concentration of the anionic hydrophilic groups at a depth half the film thickness from the surface of the acrylic resin film, the compound (A) having in the molecule thereof one or more anionic hydrophilic groups and one or more groups selected from groups having a polymerizable carbon-carbon double bond, amino groups, mercapto groups and hydroxyl groups.
问题
提供亲水性改性丙烯酸树脂薄膜,使其具有优异的防雾性能和防污性能,以及高透明度。
[解决方案]
本发明的一种改性丙烯酸树脂薄膜是通过用一种化合物(A)处理具有阴离子亲水基团的丙烯酸树脂薄膜的表面而获得的,该丙烯酸树脂薄膜的表面上的阴离子亲水基团的浓度高于从丙烯酸树脂薄膜表面算起的一半膜厚深度处的阴离子亲水基团的浓度、化合物 (A) 分子中具有一个或多个阴离子亲水基团和一个或多个选自具有可聚合碳碳双键的基团、氨基、巯基和羟基的基团。
