A composition contains (A) a polyurethane produced from a polyisocyanate and a polyol; and (B) an aldimine group-containing compound of formula (I). m : integer 1-4; p : integer 1-6; q : integer 0-5 with the proviso that p + q= 2-6; R 1>6-30C hydrocarbyl optionally with a heteroatom, especially an oxygen ether, or is a group of formula (II); R 6>2-20C hydrocarbylene optionally with a heteroatom, especially an oxygen ether; R 7>1-20C hydrocarbyl; R 2> and R 3>1-12C hydrocarbyl or together form a 4-20C hydrocarbylene which is part of an optionally substituted 5-8 (especially 6)C carbocyclic ring; R 4>an (m + 1)-valent 2-12C hydrocarbon group optionally with a heteroatom, especially an oxygen ether, or a tert. amine nitrogen; R 5>a (p + q)-valent organic optionally heteroatom-containing group such as obtained by removal of (p + q) NCO groups from R 5>[NCO] p+q or is N, NR 14>, O, OC(O)O, Si, P(O)O 3 or SO 2; R 14>1-20C hydrocarbyl; X : O, S or NR 8>; and R 8>1-20C hydrocarbyl optionally with at least one carboxylic acid ester, nitrile, nitro, phosphonic acid ester, sulfo or sulfonic acid ester group or is a group of formula (III).
