摘要： An aqueous polyurethane dispersion includes particles of polyurethane in water, wherein the polyurethane is derived from an organic diisocyanate, a hydrophilic monomer, a neutralizer, a chain extender, and a polyester resin, the polyester resin being a random copolymer having randomly distributed subunits of formula 1: where: R is ethylene, octylene, or decylene, a is from about 40 to about 100 mole % of the polyester resin, b is from 0 to about 30 mole % of the polyester resin, c is from 0 to about 30 mole % of the polyester resin, and a+b+c=100 mole % of the polyester resin.
