Abstract: An aqueous composition comprises a water-emulsifiable polyisocyanate (A), the water-emulsifiable polyisocyanate (A) being a reaction product of a polyisocyanate (B) with a compound (C) which contains at least one sulfonic acid group or its anion, and at least one isocyanate-reactive group. The composition further comprises a fragrant (D1) with at least one hydroxyl and/or aldehyde group. It has been found that the addition of the fragrant (D1) can mask unpleasant odors of the composition. This is particularly the case when organic co-solvents such as propylene glycol-n-butyl ether and/or 3-methoxy-1-butyl acetate are used. The storage stability and performance of the polyisocyanates are not affected by the addition of the fragrant (D1). Further aspects of the invention are the use of a composition according to the invention as an adhesive, a coating or an impregnating material and a substrate coated with a composition according to the invention.
