Abstract
A saturated cross-linkable binder composition adapted for preparing coatings having a non-glossy surface is disclosed which comprises: (a) at least one cross-linkable resin selected from the group consisting of saturated polyester resins and epoxide resins; (b) a cross-linking agent wherein the functional groups are selected from the group consisting of acid groups and acid anhydride groups and, in case the cross-linkable resin is a saturated polyester resin, also masked isocyanate groups; and, (c) having associated therewith a salt of an at least bivalent metal ion and an organic acid anion selected from the group consisting of carboxylic anions and acetylacetonate. These binder compositions are particularly useful as binding agents in powderous paint compositions which yield a paint coating having a non-glossy and textured surface.
