Abstract: Described are glycerol diesters 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: and the radicals R3, R4, R5, and R6 independently of one another are a saturated, aliphatic radical having 1 to 20 carbon atoms, with the proviso that the radicals R3 and R4 together contain at least 5 carbon atoms and the radicals R5 and R6 together contain at least 5 carbon atoms. Also described is a process for preparing the glycerol diesters, use thereof as reactive diluents, coating materials comprising the glycerol diesters, multicoat paint systems and their production, comprising the use of the coating materials, and also to substrates coated therewith.
