The present invention relates to a polymer that can be produced by reacting at least one polymer that is obtainable by reacting (a) dimer fatty acids with at least (b) one polyether comprising a C3 to C6 alkylene radical and with a number average molecular mass of from 450 to 2200 g/mol, the components (a) and (b) being employed in a molar ratio of 0.7/2.3 to 1.3/1.7 and the resulting polymer having a number average molecular mass of from 1500 to 5000 g/mol and an acid number < 10 mg KOH/g, at least one polyether comprising a C3 to C6 alkylene group and with a number average molecular mass of from 250 to 3000 g/mol, at least one compound with at least one functional group capable of forming anions and/or at least one anionic group, and at least one, in particular at least two, functional groups capable of reacting with isocyanates, at least one polyisocyanate, and optionally at least one mono-ol or diol, at least one compound comprising more than two functional groups capable of reacting with isocyanates, and optionally neutralizing the group of component (C) capable of forming anions. |
