Document Type and Number:
WIPO Patent Application WO/2019/163570
Kind Code:
A1
Abstract:
Disclosed is a surface treatment agent which contains:
(A) a water repellent oil repellent polymer which has a repeating unit derived from at least one water repellent oil repellent monomer that is selected from among (A1) fluorine-containing monomers and (A2) non-fluorine monomers having a hydrocarbon group with 7-40 carbon atoms;
(B) a silicone polymer represented by formula R53
3Si-O-[-Si(R51)2-O-]a-[-Si(R51)(R52)-O-]b-SiR53
3 (wherein each R51 independently represents a hydrogen atom, an alkyl group having 1-20 carbon atoms, an aryl group having 6-20 carbon atoms or an alkoxy group having 1-4 carbon atoms; each R52 independently represents a saturated hydrocarbon group having 23-40 carbon atoms; each R53 independently represents a hydrogen atom, an alkyl group having 1-20 carbon atoms, an aryl group having 6-20 carbon atoms, an alkoxy group having 1-4 carbon atoms or a saturated hydrocarbon group having 23-40 carbon atoms; a represents an integer of 0 or more; b represents an integer of 1 or more; and (a + b) is 10-200); and
(C) a liquid medium. This surface treatment agent imparts excellent water and oil repellency, especially excellent water repellency to a base material such as fiber.
