Abstract
A process is provided for preparing storage stable, aqueous dispersions of oligourethanes or polyurethanes in admixture with auxiliary agents and additives which are not soluble nor dispersible in water. The oligourethanes or polyurethanes are rendered dispersible in water by incorporating ionic and/or non-ionic hydrophilic groups. In order that the final product remains storage stable, the auxiliary agents or additives are added to the oligourethanes or polyurethanes before they are dispersed in water.
