Aqueous resin emulsion comprises a resin, which is obtained by reaction of a composition comprising: at least one low-molecular multi-valued alcohol with at least two hydroxyl groups; at least one polyetherpolyol with a molecular weight of 400-8000 g/mol; at least one monobasic carbonic acid; and at least one polybasic carbonic acid with at least two groups of carbonic acids and/or their anhydride, where the resin emulsion is modified by supply basic groups in a molecule that contains at least two basic groups. Independent claims are included for: (1) the preparation of the resin comprising reacting the composition to give the resin and modifying the resin by introduction of basic groups; (2) the resin that is obtained by the process; and (3) a varnish film that is obtained by the resin emulsion under evaporation of the aqueous solvent. |
