Abstract
The invention relates to a self-emulsifying polymer US comprises Michael donor groups, wherein the Michael donor groups are acidic C—H groups from activated methylene and/or methine groups, to an aqueous polymer dispersion containing a mixture thereof with compounds having Michael acceptor groups which are activated olefinically unsaturated groups, activated by an electron-withdrawing group, and a catalyst to promote the Michael reaction, to a paint binder prepared from the mixture and the catalyst, and to coating compositions comprising the paint binder and appropriate additives.
