Abstract

The present invention relates to a composition comprising (A) at least one carboxy-functional polyester having an acid number in the range from 20 to 250 mg KOH/g, prepared using at least one difunctional monomer (a1) with aliphatic groups having 12 to 70 carbon atoms between the functional groups, and also (B) at least one synthetic layered hydroxide, where the at least one layered hydroxide (B) is prepared in the presence of the polyester (A). The present invention further relates to the preparation of the composition and also to the use of the composition as coating material.
