Abstract
A water-dispersible, cyclocarbonate-functionalized vinyl copolymer binder, a process for the preparation of the binder, an aqueous dispersion containing the binder, a system comprising the binder, water and an (amine) curing agent and the use of the binder for the production of a hardened coating are proposed. It was surprisingly found that this binder, in which the emulsifier groups according to the invention are incorporated in the polymer chain, gives stable aqueous dispersions having a solids content of up to a 30% by weight.
