Abstract

The present invention addresses the problem of providing the following: a film that exhibits an excellent balance of hydrophilicity and resistance to wear, exhibits minimal hydrophilicity degradation upon exposure to water, and is also highly weather-resistant; and a polymer and polymer composition that yield said film. Said film is made from either: a specific copolymer (i), each molecule of which contains a sulfonic-acid-containing group, an epoxy group, and a specific alkoxysilyl group; or a composition containing said copolymer (i).

Description

technical field [0001] The present invention relates to a film obtained from a hydrophilic copolymer or a composition containing the copolymer, which has antifogging properties, antifouling properties, and antistatic properties, and is excellent in abrasion resistance and weather resistance, and uses thereof. Background technique [0002] In recent years, there has been an increasing demand to improve fogging and fouling that occur on substrate surfaces such as plastic surfaces and glass surfaces. [0003] As a method for solving the problem of fogging, an antifogging coating in which a reactive surfactant is added to an acrylic oligomer has been proposed, and it is considered that the cured film obtained by the antifogging coating has improved hydrophilicity and water absorption (Non-Patent Document 1). In addition, as a method to solve the problem of fouling, for example, anti-pollution materials having self-cleaning properties (anti-pollution properties), which improve t...
