Patent number: 11608444Abstract: Although a composition for formation of a coating film is sometimes required to have satisfactory storage stability, it could not be said that a conventionally known composition has sufficient storage stability. It is an object of the present invention to provide a composition comprising an organosilicon compound which is excellent in storage stability. The present invention provides a composition comprising an organosilicon compound (A) represented by the following formula (a1), a metal compound (B) represented by the following formula (b1), a carboxylic acid compound (C), and an acid catalyst.Type: GrantFiled: August 16, 2021Date of Patent: March 21, 2023Assignee: SUMITOMO CHEMICAL COMPANY, LIMITEDInventors: Michiru Uehara, Tomohiro Ito

Patent number: 10988634Abstract: A mixed composition comprising an organosilicon compound represented by the following formula (a1), a solvent, water, and a carboxylic acid compound, wherein a mass ratio of the water to the organosilicon compound is 30.0 or more. In the following formula (a1), a plurality of Aa1 each independently represent a hydrolyzable group, Za1 represents a hydrocarbon chain-containing group, x is 0 or 1. Ra10 represents an alkyl group having 6 to 20 carbon atoms in which a part of methylene groups may be replaced with an oxygen atom and one or more hydrogen atoms may be replaced with a fluorine atom, and Za1 and Ra10 may be the same or different.Type: GrantFiled: March 29, 2019Date of Patent: April 27, 2021Assignee: SUMITOMO CHEMICAL COMPANY, LIMITEDInventors: Michiru Uehara, Tomonori Miyamoto, Yasuharu Shimazaki
