Procedure: BM 2: 500 parts of an epoxy resin based on Bisphenol A and epichlorohydrin (epoxy equivalent weight about 500) are dissolved in 214 parts propyleneglycol monomethylether and reacted at 110° C. with 83 parts of a semiester of phthalic acid anhydride and 2 ethylhexanol, in the presence of 0.5 parts of triethylamine as catalyst, to an acid value of below 3 mg KOH/g. Then, 120 parts of an NH-functional oxazolidine of aminoethylethanolamine, 2-ethylhexylacrylate and formaldehyde, and 26 parts diethylaminopropylamine are added and the batch is reacted at 80° C. to an epoxy value of practically zero. The batch is diluted with 200 parts propyleneglycol monomethylether. 70 parts (resin solids) of this oxazolidine modified epoxy resin amine adduct are homogenized for 30 minutes at 50° C. with 30 parts based on resin solids of a crosslinking component obtained through reaction of 1 mole of a toluylene diisocyanate semi-blocked with 2-ethylhexanol and 0.33 moles triethanolamine. The reaction is carried out in a 70% solution of diethyleneglycol dimethylether, at 50 to 60° C. until all isocyanate groups have reacted.
