Abstract: Described are coating materials comprising (a) at least one polymeric polyol selected from the group consisting of poly(meth)acrylate polyols, polyester polyols, polyurethane polyols and polysiloxane polyols, (b) at least one crosslinking agent selected from the group consisting of blocked and nonblocked polyisocyanates, amino resin crosslinkers, and TACT, and (c) at least one glycerol diester of the general formula (I) wherein one of the two radicals R1 or R2 is hydrogen and the radical of the two radicals R1 and R2 that is not hydrogen is a radical the radicals R3, R4, R5, R6, R7, and R8 independently of one another are hydrogen or a saturated, aliphatic radical having 1 to 20 carbon atoms, with the proviso that the radicals R3, R4 and R5 together contain at least 5 carbon atoms and the radicals R6, R7 and R8 together contain at least 5 carbon atoms. Also described are multicoat paint systems and their production, the use of the coating materials, and substrates coated therewith.
