Claim Text:
1. An aqueous binder, comprising as active constituents: a polymer A obtained by free-radical polymerization, the polymer comprising >5 wt% and <100 wt% of an α,β-monoethylenically unsaturated monocarboxylic acid or an α,β-monoethylenically unsaturated dicarboxylic acid in polymerized form, a polyol compound B having at least two hydroxyl groups and a molecular weight of <1000 g/mol, and a salt compound C which at 20° C. and 1 atm absolute has a solubility of >10 g in 100 g of deionized water; wherein the salt compound C is selected from the group consisting of sodium chloride, potassium chloride, sodium sulfate, and potassium sulfate, the amount of salt C is >0.1 and <40 wt %, based on summed total amounts of polymer A and polyol B, the aqueous binder comprises no phosphorus-containing reaction accelerants and the weight ratio of polymer A to polyol B is in the range of 100:1 to 1.5:1.
