Abstract:
The present invention relates to a nonaqueous coating material composition comprising at least one compound (A) having at least two amino groups, and at least one oligomeric and/or polymeric compound (B) having at least two alkylidene-1,3-dioxolan-2-one groups, wherein the compound (B) is obtainable using at least one monomer (B1) of the formula (I) where R1, 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, R3 more particularly being hydrogen; R4 is hydrogen, C1-C4 alkyl, CH2COOR8, phenyl or phenyl-C1-C4 alkyl; R5, 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, A more particularly being C1-C4 alkanediyl; X is O or NR7; Z is a chemical bond, PO2, SO2, or C═O, Z more particularly being C═O; Y is a chemical bond, CH2, or CHCH3; R7 where present is C1-C6 alkyl; and R8 where present is hydrogen or C1-C6 alkyl; and at least two different comonomers (B2) and (B3) which are each different from the monomer (B1). The present invention further provides the coatings produced from these coating material compositions, and also the use thereof.
