Abstract:
Aqueous polyurethane dispersions prepared by dispersing a polymer resin in water, wherein the polymer resin is prepared by reacting a reaction mixture comprising:A) at least one condensation product of (i) an oxidatively non-drying fatty acid and (ii) a dialkanolamine and having a number average molecular weight of <500, B) one or more polyisocyanates, C) one or more hydrophobic, water immiscible polyols having a number average molar weight of from 500 to 6000 and containing no functional groups being capable of oxidative drying, D) one or more compounds which contain an ionic group or a group capable of forming an ionic group, and E) one or more polyols and/or polyamines having a number average molecular weight of <500, F) optionally, monoalcohols and/or monoamines and G) optionally OH- and/or NH-functional, nonionically hydrophilic polyoxyalkylene ethers.
