Abstract: Storage-stable, aqueous resin solution having a pH of at most 7, containing as the resin a water-dilutable polyamido-amine/epichlorohydrin resin (A) obtained by reacting a water-dilutable, basic polyamido-amine (B), consisting of an acid component (B1), and an amine component (B2) with epichlorohydrin (C), the content of organically bound chlorine in the resin (A) being at most 4% by weight and the component (B2) - if the acid component (B1) is an aliphatic or aromatic carboxylic acid or a functional derivative thereof, if appropriate in a mixture with an aminocarboxylic acid or lactams thereof - consisting of a mixture of polyamines and alkanolmonoamines. The invention also relates to a process for the preparation of these products and to their use, especially for increasing the wet strength of paper.
