Air-drying, water-reducible, acid-functional polyurethanes are obtained by reacting: (i) a fatty amide diol obtained by the reaction of a fatty acid or fatty acid derivative and an N,N-dialkanol amine; and (ii) a diisocyanate; and (iii) an acid-functional compound which also has two active hydrogen groups, other than acid groups, which are reactive with the diisocyanate.
