Abstract
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 PA1 (A) a polymer having a repeating unit derived from maleate or fumarate having at least one fluoroalkyl group; PA1 (B) a fluoroalkyl group-containing copolymer having: PA2 (I) a repeating unit derived from a monomer containing a fluoroalkyl group, PA2 (II) a repeating unit derived from a monomer containing no fluorine, PA2 (III) a repeating unit derived from vinyl chloride, and PA2 (IV) a repeating unit derived from a crosslinking monomer; and PA1 (C) an acrylic copolymer containing no fluorine, which is optionally present.
