Abstract:
A water and oil repellent composition, comprising:(A) a polymer comprising (A1) polymerized units of a (meth)acrylate (a1) having a poly-fluoroalkyl group; and (A2) polymerized units of a polymerizable monomer (a2) which comprises a polymerizable unsaturated group and a hydroxyl group and in which the polymerizable unsaturated group and the hydroxyl group are connected to each other through 7 or more covalent bonds; (B) a surfactant comprising a nonionic surfactant in an amount of from 60 to 100 wt %; (C) an aqueous medium selected from the group consisting of i) water only, and ii) a mixture of water and a water-soluble organic solvent; and (D) a cross-linkable compound; wherein said nonionic surfactant in said surfactant (B) is selected from the group consisting of (b1) a nonionic surfactant comprising units obtained from a polyoxyalkylene monoalkyl ether, a polyoxyalkylene monoalkenyl ether or a polyoxyalkylene monoalkpolyenyl ether; (b2) a nonionic surfactant comprising units obtained from a compound which has at least one carbon-carbon triple bond and at least one hydroxyl group in its molecule and which exhibits a surface activity; (b3) a nonionic surfactant comprising units obtained from a compound in which a polyoxyethylene moiety having two or more oxyethylenes chained and a moiety having two or more oxyalkylenes having a carbon number of 3 or more chained, are connected, and both terminals are hydroxyl groups; (b4) a nonionic surfactant having an amine oxide moiety in its molecule; and (b5) a nonionic surfactant comprising units obtained from a condensate of a polyoxyethylene mono(substituted phenyl) ether, or a polyoxyethylene mono(substituted phenyl) ether.
