Process for the preparation of polyamidoimide resins, in which the centers of the polyamidoimide resins which are reactive toward moisture are reacted with one or more compounds of the following general H—X—R1, in which, where X=oxygen, R1 is a straight-chain or branched alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms or an aralkyl group and, where X═NR2, R1 is a straight-chain or branched alkyl group having 1 to 6 carbon atoms, a cycloalkyl group having 3 to 6 carbon atoms or an aralkyl group or an aryl group and R2 is a straight-chain or branched alkyl group having 1 to 6 carbon atoms, an aralkyl group or an aryl group, or R1 and R2 together form a cycloalkyl radical having 4 or 5 methylene groups, it being possible for a methylene group to be replaced by oxygen or an NR3 group, and R3 being a straight-chain or branched alkyl group having 1 to 3 carbon atoms, and polyamidoimide coating materials which are prepared by the process.
