摘要：
A graft polyurethane copolymer dispersion can include dispersed polyurethane particles including a graft polyurethane copolymer. The graft polyurethane copolymer in this example includes a polyurethane backbone, a graft side-chain polymer attached to the polyurethane backbone, sulfonic acid groups, and isocyanate-generated amines. The graft side-chain polymer can include a poly(meth)acrylic moieties with C1 to C12 alkyl pendant groups, polyalkylene oxide pendant groups, or a combination thereof.
