Patents by Inventor Michiru UEHARA

Michiru UEHARA has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11608444
    Abstract: 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.

  • Patent number: 10988634
    Abstract: 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.
