Title:
HYDROPHILIC-COATING-FILM FORMING COMPOSITION AND HYDROPHILIC COATING FILM USING SAME
Document Type and Number:
WIPO Patent Application WO/2018/230514
Kind Code:
A1
Abstract:
Provided are a hydrophilic coating film of which hydrophilicity and anti-fogging properties do not deteriorate even during storage under high-temperature and high-humidity conditions and a hydrophilic-coating-film forming composition with which said film is obtained. The present invention provides a hydrophilic-coating-film forming composition containing a siloxane monomer having a betaine group having a positive charge on a nitrogen atom in a nitrogen-containing heterocyclic structure, such as a compound represented by formula [1], and water or an organic solvent.
[1]
(In the formula, R1 represents an alkyl group having a carbon number of 1 to 5; R2 represents an alkyl group, etc. having a carbon number of 1 to 5; p represents 1 to 3; q represents 0 to 2 when p is 1, 0 to 1 when p is 2, and 0 when p is 3; L represents a straight-chain or branched-chain alkylene group that has a carbon number of 1 to 20 and that may have a hetero atom; X represents a single bond, etc.; Y represents a divalent organic group having a nitrogen-containing hetero ring; M represents a straight-chain or branched-chain alkylene group having a carbon number of 1 to 10 and bonded to a nitrogen atom in Y, wherein either one of M and L forms an N+ moiety through bonding to the nitrogen atom in Y; and Z represents COO-, SO3
-, etc.)
