Title:
SINGLE LAYER FILM AND HYDROPHILIC MATERIAL COMPOSED OF SAME
Document Type and Number:
WIPO Patent Application WO/2007/064003
Kind Code:
A1
Abstract:
Disclosed is a single layer film having at least one anionic hydrophilic group selected from a sulfonic acid group, a carboxyl group and a phosphoric acid group, wherein the anion concentration ratio (Sa/Da) between the anion concentration in the surface (Sa) and the anion concentration in the deep portion (Da) is not less than 1.1. This single layer film is composed of a copolymer having a contact angle with water of not more than 30º which is obtained by polymerizing a composition which contains a compound (I) represented by the following general formula (1): [X]s[M1]l[M2]m, and a compound (II) having two or more (meth)acryloyl groups in a molecule at a molar ratio of 15:1-1:30. Such a single layer film has high hydrophilicity and high surface hardness, while being excellent in antifog property, antifouling property and antistatic property. Consequently, the single layer film is useful for antifog materials, antifouling materials, antistatic materials and multilayer bodies.
