Abstract

Provided is an aqueous-dispersible, self-crosslinkable interpenetrating polymer network composition which comprises an aqueous-dispersible, isocyanate-based thermoplastic polymer containing urethane and/or urea linkage and an interpenetrating polymer containing latent reactive functionality, whereby the two polymers are at least partially entangled with each other on a molecular level. Also provided are aqueous dispersions of such self-crosslinkable interpenetrating polymer networks, methods of producing such aqueous dispersions, coating compositions therefrom and coated substrates and films obtained from it.
