Abstract
Aqueous binders for liquid coating agents which contain a film-forming, aqueous plastic dispersion and a crosslinking component can be stored in ready-to-use form and quickly harden after being processed into a coating, at room temperature or a temperature just slightly above, forming a hard, dry, crosslinkable film. The plastic dispersion is an emulsion polymer with polymerized units of an ethylenically-unsaturated, radically polymerizable monomer with an alkylene urea side group. The crosslinking agent contains at least two, possibly protected, aldehyde groups.
