1. An aqueous binder composition comprising:
a long-chain polyol having at least two hydroxyl groups and a number average molecular weight of at least 2,000 Daltons;
at least 70 wt. % of a polymeric cross-linking agent comprising at least two carboxylic acid groups; and
a short-chain polyol having at least two hydroxyl groups and a number average molecular weight less than 2,000 Daltons;
wherein the cross-linking agent is free of a monomeric carboxylic acid,
wherein a ratio of long-chain polyol to short-chain polyol is from 0.1/0.9 to 0.9/0.1, and wherein the wt. % is based on the total solids content of the aqueous binder composition.
