Abstract

To provide a material that does not contain fluorine or excludes fluorine as much as possible, has high liquid repellency performance, and is soluble in an aqueous solvent that contributes to VOC reduction. 【Solution means】A block copolymer containing structural unit (1) and structural unit (2), wherein the abundance ratio of structural unit (1) is 0.05 to 0.2 in molar ratio and the abundance ratio of structural unit (2) is 0.7 to 0.95 in molar ratio with respect to the structural units of the entire block copolymer. TIFF2026098900000030.tif2599 (In the formula, X 1 is -O- or -NH-, R 10 is an alkylene or phenylene having 2 to 12 carbon atoms, R 11 is a linear, branched, or cyclic hydrocarbon group having 6 to 30 carbon atoms.) TIFF2026098900000031.tif19129 (In the formula, X 2 is the same as the above X 1 and R 2 is a monovalent organic group having -(CH2CH2O)n-, and n is an integer from 2 to 30.)
