Abstract
A stainproofing polymer having: (i) a reactive group selected from the group consisting of a carboxyl group or its salt, a hydroxyl group, an epoxy group, a phosphoric acid group, an alkoxysilane group, an imine group, a sulfonic acid group, an amino group, an isocyanate group and a blocked isocyanate group; and (ii) a fluoroalkyl group, characterized in that a melting point of a monomer having a fluoroalkyl group, which constitutes the polymer, is at least 70° C. and a melting point of the stainproofing polymer is at least 50° C., gives durability capable of maintaining sufficient water- and oil-repellency after cleaning.
