Thermosetting resinous binder compositions, their preparation and their use as coating materials.

摘要

This invention provides thermosetting resinous binder compositions containing a hydroxyl group-containing non-acidic resinous compound, a beta-hydroxyl ester group-containing polyester cross-linking agent and a transesterific- tion-promoting metal compound, the resinous compound and/or the polyester having a hydroxyl or beta-hydroxyl ester functionality of more than 2, wherein the beta hydroxyl ester groups in the polyester are substituted in the gamma-position by a hydroxyl or amino group, or a transferable ester group derived from a polycarboxylic acid, their preparation and tbeir use as coating materials.
