description | An aqueous dispersion of an aqueous polyurethane having an ionic functional group, polyoxyethylene units and terminal hydrazine functional groups is provided. Content of the ionic functional group is about 5 to about 180 milliequivalent per 100 g of the aqueous polyurethane, and content of the polyoxyethylene unit is about 20 % by weight or less of a weight of the aqueous polyurethane. The aqueous dispersion is used for a composition for ink, coating or adhesive. Storage stability, water resistance, pigment dispersibility, and adhesion to various kinds of substrates, particularly non-polar substrates, of the aqueous dispersion and the composition are excellent. |
