The invention relates to thermally hardenable one-component coating materials having 40 80 wt. % of a solid body and an electric resistance ranging from 600 to 1.300 kO, made of, respectively in relation to the coating material, (A) 18 - 25 wt. % of a (meth)acrylate(co)polymer having a hydroxyl number of between 80 - 240 mg KOH/g, an acid value of between 0 - 40 mg KOH/g, an average molecular weight number of between 1.500 - 20.000 daltons, a glass transition temperature of between -40 - +80 °C and a primary hydroxyl group content of > 50 equivalent %, in relation to the total amount of hydroxyl groups present in (A), (B) 2 - 7 wt. % of a tris(alkoxycarbonylamino)triazine, (C) 2 - 8 wt.- % of a polyisocynate blocked with a pyrazole, (D) 3 - 9 wt. % of a water-soluble, reactive melamine formaldehyde resin, (E) 3 -9 wt. % of a water insoluble, highly reactive melamine formaldehyde resin, (F) 0 - 40 wt. % of an additional substance and (G) 20 - 60 wt. % of an organic solvent. The invention also relates to a method for the production and use thereof.
