Disclosed is a soil release agent composition essentially containing a fluorine-containing copolymer, which is essentially composed of (a) a fluorine-containing monomer having a fluoroalkyl group, (b) a polyalkyleneglycol (meth)acrylate, (c) a monomer having an acetoacetyl group and (d) a monomer having a cation-donating group, and a crosslinking agent. This soil release agent composition imparts a base material such as a fiber fabric with excellent oil repellency, antifouling property and soil releasing property, while maintaining washing resistance of the base material. The monomer (a) is preferably represented by the following formula (1). n CH 2 ═C(—X)—C(═O)—Y-Z-Rf (1) n (In the formula, X represents a hydrogen atom, a linear or branched alkyl group having 1-21 carbon atoms, a fluorine atom, a chlorine atom or the like; Y represents —O— or —NH—; Z represents an aliphatic group having 1-10 carbon atoms, an aromatic group having 6-18 carbon atoms, an alicyclic group or the like; and Rf represents a linear or branched fluoroalkyl group having 1-21 carbon atoms.) |
