Zusammenfassung:	PCT No. PCT/EP95/02740 Sec. 371 Date Jan. 15, 1997 Sec. 102(e) Date Jan. 15, 1997 PCT Filed Jul. 13, 1995 PCT Pub. No. WO96/03458 PCT Pub. Date Feb. 8, 1996The present invention relates to a solution of a polyacrylate resin in one or more organic solvents, containing one or more phosphites, characterized in that the solution contains from 0.05 to 1.0% by weight, based on the solids content of the acrylate resin solution, of one or more phosphites and in that the phosphite has been added, either partially or entirely, after the polymerization reaction, at a temperature below the polymerization temperature. The present invention further relates to coating compositions which contain these polyacrylate resin solutions, their use in processes for producing a multilayer protective and/or decorative coating on a substrate surface, and the use of the coating compositions in the automotive refinishing sector.
