Stainproofing agent composition

摘要

The present invention provides a stainproofing agent composition having the durability capable of maintaining sufficient water- and oil-repellency as well as stainproofing properties before and after cleaning. Disclosed is a stainproofing agent composition containing (A) a polymer having a repeating unit derived from maleate or fumarate having at least one fluoroalkyl group; (B) a fluoroalkyl group-containing copolymer having: (I) a repeating unit derived from a monomer containing a fluoroalkyl group, (II) a repeating unit derived from a monomer containing no fluorine, (III) a repeating unit derived from vinyl chloride, and (IV) a repeating unit derived from a crosslinking monomer; and (C) an acrylic copolymer containing no fluorine, which is optionally present.
