Abstract
A water- and oil-repellent agent that is an aqueous dispersion containing (A) a fluorine-free polymer having repeating units derived from a fluorine-free (meth)acrylic acid ester monomer, (B) a wax, (C) an aqueous medium, and (D) an emulsifier. The fluorine-free (meth)acrylic acid ester monomer is a compound represented by the formula CH═CA-C(═O)—O-Awhere Ais a hydrogen atom or a methyl group and Ais a linear or branched Chydrocarbon group. The emulsifier includes a sorbitan ester and another emulsifier, and the emulsifier has a hydrophilic-lipophilic balance (HLB) of 7.5 to 13.5. Also disclosed is a method of producing the water- and oil-repellent agent and a method of producing a treated substrate by applying the water- and oil-repellent agent to a substrate.
