Abstract: The invention concerns novel polyester polyols and their use as the polyol component in two-component polyurethane paints. The polyester polyols produce films which display exceptional properties after hardening. Owing to the low solvent requirement when reaction paints are prepared, they are particularly environmentally friendly. The permanence of the gloss of the hardened coatings should be stressed in particular.

Abstract: Copolymer solutions, based on addition products of .alpha., .beta.-unsaturated carboxylic acid with glycidyl esters and copolymerisable .alpha., .beta.-unsaturated monomers, with a remarkably high as-copolymerized solids content of about 80% by weight and which can be processed with polyisocyanates into high solids two-component coatings having a good processing viscosity. The copolymers contain a methoxy-functional polysiloxane as copolymerized units. The copolymers can be processed with amino resins into binders for baking finishes which used as improved clear coatings for automotive topcoating produce paint films which possess excellent abrasion resistance in car washes.

Abstract: Alkyd resins, processes for their production, and their use are disclosed, these resins being distinguished by the fact that, in production, no organic solvents are used. The alkyd resins are clear and almost odorless and have a low viscosity. When used as a bonding agent in brush paints final products produced from these resins should not contain more than 10 to 15% by weight of organic solvents. The alkyd resins are obtainable from the following ingredients:A) 58.90 to 75.25% by weight of drying fatty acids,B) 7.00 to 16.25% by weight of pentaerythritol,B') 0 to 3.00% by weight of glycerolC) 0.07 to 1.40% by weight of hypophosphorous acid,D) 5.00 to 29.00% by weight of trimellitic anhydride andE) 0 to 5.00% by weight of triphenyl phosphite, where the components A), B), B'), C), and E) must make up 100% by weight.

Abstract: Copolymerizate solutions are disclosed containing copolymerizates based on addition products of an .alpha.,.beta.-unsaturated carboxylic acid with a glycidyl ester and copolymerizable .alpha.,.beta.-unsaturated monomers with and without hydroxyl groups which are present after the copolymerization with unusually high solid matter content (approximately 78-83% by weight solid matter) and which can be reacted with polyisocyanates to form reaction lacquers with a high solid matter content with good processing viscosity. These lacquers are especially well suited for automobile finishes.
