Abstract: This invention relates to coating media based on one or more styrene-free, unsaturated polyester resins, which containA) one or more unsaturated polyesters obtainable by the reaction ofa) 0.5 to 1.0 mole of at least one alpha,beta-ethylenically unsaturated dicarboxylic acid or the anhydride thereof,b) 0 to 0.5 mole of at least one aromatic, aliphatic and/or cycloaliphatic saturated dicarboxylic acid or the anhydride thereof,c) 0.4 to 0.8 mole of at least one aliphatic saturated dihydric alcohol,d) 0.5 to 1.2 mole of at least one hydroxy-functional allyl ether,B) one or more polyglycol diacrylates of general formula ##STR1## where n=2-5 and m=2-5, particularly dipropylene glycol diacrylate, C) one or more initiators, andoptionally one or more organic solvents, one or more pigments and/or extenders, as well as accelerators, catalysts and/or customary lacquer additives.

Abstract: This invention relates to two-component, solvent-thinnable coating media based on a polyisocyanate component and a component which reacts with isocyanate. The coating media contain one or more hydroxy-functional copolymers, one or more secondary polyamines containing ester groups, one or more aliphatic and/or cycloaliphatic polyisocyanates containing allophanate groups, extenders and/or pigments and optionally one or more organic solvents and customary lacquer additives. 60 to 75% by weight of aluminium hydroxide and calcium magnesium carbonate are contained in total, with respect to the total amount of extenders and/or pigments.

Abstract: The description relates to coating agents for use as primers and fillers in the manufacture of multilayer lacquer coatings, more particularly in the motor-vehicle sector.The coating agent contains a binder mixture ofA) 60-75 wt. % of a hydroxy-functional copolymer with an OH number of 110 to 170 mg KOH/g, obtainable froma) 5-60 wt. %, preferably 10-30 wt. % of at least one diester of an alpha, beta-olefinically unsaturated dicarboxylic acid with saturated monohydric alcohols containing 1-8 carbon atoms,b) 10-70 wt. %, preferably 35-60 wt. % of one or more vinyl aromatic hydrocarbons,c) 0-30 wt. %, preferably 0-15 wt. % of one or more glycidyl esters of aliphatic saturated monocarboxylic acids branched in the alpha position,d) 25-50 wt. % of at least one hydroxy alkyl ester or a mixture of at least one alkyl ester and one hydroxyl alkyl ester of an alpha, beta-olefinically unsaturated monocarboxylic acid, ande) 0-10 wt. % of one or more alpha, beta-unsaturated monocarboxylic acids,B) 1-6 wt.
