Aqueous cationic polyurethane dispersions |
| 摘要 |
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. |

1. An aqueous cationic polyurethane dispersion (PUD) comprising an aqueous dispersion of a polyurethane having a polyurethane backbone with one or more tethered tertiary amino groups laterally attached to said polyurethane backbone wherein said tertiary amino groups are optionally partially or fully neutralized or quaternized and wherein said tertiary amine groups are separated from said polyurethane backbone by at least two intervening atoms in their tethering group. |
