An aqueous cationic polyurethane dispersion for waterborne digital print and other applications comprising an aqueous dispersion of polyurethane having properly positioned tertiary amino groups, e.g., tethered tertiary amino group separated from backbone by at least two intervening atoms or terminal tertiary amino groups with multiple tertiary amino groups per terminus, where said amino groups are optionally partially quaternized and/or neutralized.
