Title:
AQUEOUS COATING MATERIAL AND COATED SUBSTRATE
Document Type and Number:
WIPO Patent Application WO/2019/009415
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing: an aqueous coating material which is capable of forming a coating film having excellent water resistance and anti-adhesiveness, and has excellent storage stability; and a coated substrate having excellent water resistance and anti-adhesiveness. The aqueous coating material contains: particles of a fluorine-containing polymer including a unit based on fluoroolefin and a unit based on a monomer having an alkyl group; particles of a silicone-modified (meth)acrylic polymer; and water, wherein the molar ratio of fluorine atoms to silicon atoms in the aqueous coating material is 10-700. The coated substrate has: a substrate; a fluorine-containing polymer disposed on the surface of the substrate; and a coating film containing a silicone-modified (meth)acrylic polymer, wherein the content of silicon in the coating film is 0.01-10 mass% with respect to the total mass of the coating film, and the molar ratio of fluorine atoms to silicon atoms on the surface of the coating film is 10-300.
