Abstract:
1. An aqueous binder, consisting essentially of, as active constituents: a) polymer A, comprising a polymer obtained by free-radical polymerization, wherein the polymer comprises, in polymerized form: wherein a total amount of the monomers A1 and A2 is 100 wt %, b) polyol B, comprising a nitrogen-free polyol compound having at least two hydroxyl groups, and c) nitrogen base C, comprising a hydroxyl-free organic nitrogen compound having at least one pK wherein the amount of nitrogen base C in the aqueous binder is ≧5 and ≦20 parts by weight, based on 100 parts by weight of polymer A and an equivalent ratio of carboxyl groups on the polymer A to hydroxyl groups on the polyol B is from 20:1 to 1:1.
