Title:
POLYMER PARTICLES AND DISPERSION LIQUID INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/235540
Kind Code:
A1
Abstract:
Provided are: polymer particles that, by being mixed in a small amount with other particles, are capable of forming a coating film having excellent flexibility and chemical resistance; and a dispersion liquid including said particles. The polymer particles include more than 20 mass% of a structural unit (X) derived from a fluorine-containing (meth)acrylic acid ester monomer (A), at least 30 mass% of a structural unit (Y) derived from a (meth)acrylic acid ester monomer (B), and more than 2 mass% to 30 mass% of a structural unit (Z) derived from a (meth)acrylic acid ester monomer (C) having a hydroxyl group, and are characterized in that the structural unit (X) derived from the fluorine-containing (meth)acrylic acid ester monomer (A) is represented by general formula (1), the structural unit (Y) derived from the (meth)acrylic acid ester monomer (B) is represented by general formula (2), and the structural unit (Z) derived from the (meth)acrylic acid ester monomer (C) having a hydroxyl group is represented by general formula (3). (In formulas (1), (2), and (3), R1 is hydrogen or a methyl group, R2 is a fluorine-containing C1-10 hydrocarbon group, R3 is a group selected from the group consisting of benzyl groups and C5-10 cyclic hydrocarbon groups, R4 is a C1-10 hydrocarbon group including a hydroxyl group, and a, b, and c represent the degree of polymerization.)
