The present invention relates to a non-aqueous coating material composition comprising at least one compound (A) having at least two amino groups and also at least one oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups, characterized in that the compound (B) is obtainable using at least one monomer (B1) of the formula (I) where R1 and R2 independently of one another are hydrogen, C1-C6-alkyl, C1-C4-alkoxy-C1-C4- alkyl, C5-C6-cycloalkyl, phenyl or phenyl-C1-C4- alkyl; R3 is hydrogen, C1-C6-alkyl, C1-C4-alkoxy-C1-C4- alkyl, C5-C6- cycloalkyl, phenyl or phenyl-C1-C4-alkyl; R4 is hydrogen, C1-C4-alkyl, CH2COOR8, phenyl or phenyl-C1-C4-alkyl; R5 and R6 independently of one another are hydrogen or C1-C4-alkyl, or else one of the radicals R5 or R6 may be COOR8 or CH2COOR8; A is a chemical bond or C1-C4-alkanediyl; X is O or NR7; Z is a chemical bond, PO2, SO2 or C=O; Y is a chemical bond, CH2 or CHCH3; R7, if present, is C1-C6-alkyl; R8, if present, is hydrogen or C1-C6-alkyl; and at least two different comonomers (B2) und (B3), each different from the monomer (B1). Also subjects of the present invention are the coatings produced from these coating material compositions, and their use. |
