Abstract
A method for preparing an acid solution by contacting at least one aromatic carboxylic or sulfonic acid with at least one polyether having blocked hydroxyl groups as a solvent. The polyether having blocked hydroxyl groups is not volatile and exhibits a surprisingly high dissolving capacity for the aromatic carboxylic or sulfonic acid. The acid solution is very compatible in curable compositions and does not cause any emission or odor or migration effects. The acid solution is particularly suitable as a constituent of polyurethane compositions having latent curing agents for accelerating the hydrolysis of the latent reactive groups.
