ABSTRACT:
The present invention provides a stainproofing agent 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 containing (A) a fluroalkyl group-containg copolymer having (I) a structure unit derived from a monomer having a fluoroalkyl group, (II) a structure unit derived from a monomer containing no fluorine, (III) a structure unit derived from vinyl chloride, and (IV) a structure unit derived from a crosslinking monomer; (B) a urethane compound having a fluoroalkyl group, or a copolymer having (V) a structure unit derived from a monomer having a fluoroalkyl group and a carbon-carbon double bond, and (VI) a structure unit derived from a monomer which contains no fluorine atom and has at least one urethane or urea linkage and one carbon-carbon double bond; and (C) an acrylic copolymer containing no fluorine.
