Title:
AQUEOUS COMPOSITION AND METHOD FOR PRODUCING SAME
Document Type and Number:
WIPO Patent Application WO/2022/270172
Kind Code:
A1
Abstract:
This aqueous composition contains: a silanol compound having an imidazolidinone group represented by general formula (1); and a condensate of the silanol compound. The content of an alcohol is less than 5 mass% relative to the content of the silanol compound and the condensate of the silanol compound. The aqueous composition suppresses the generation of alcohols, suppresses excessive condensation of the silanol compound, prevents an increase in molecular weight over time, and yields a colorless transparent aqueous solution. (In the formula, R1 denotes a halogen atom or a methyl group, R2 denotes an unsubstituted divalent hydrocarbon group having 1-8 carbon atoms, and n denotes an integer between 0 and 2.)
