Abstract
A powdery or granulated composition, containing: (a) a copolymer containing, in polymerized form, a C1- to C4-alkyl ester of acrylic or methacrylic acid and an alkyl(meth)acrylate monomer containing a tertiary amino group in an alkyl radical; (b) 0.5 to 10% by weight based on (a) of a dicarboxylic acid having 3 to 10 carbon atoms; and (c) 5 to 20% by weight based on (a) of a fatty monocarboxylic acid having 8 to 18 carbon atoms, where the composition contains at least by 30% by weight of (a), (b), and (c).
