| 摘要 |
A topcoating (14) is disclosed for a face material (12) which exhibits desirable ink anchorage, anti-pinholing properties, moisture/water resistance, optical characteristics and/or anti-blocking properties. In one embodiment, the topcoating comprises a formulation of polyurethane and polyurethane acrylate. Suitably, the polyurethane is an aliphatic polyurethane and/or the polyurethane acrylate is an aliphatic polyurethane acrylate. In one suitable embodiment, either or both the polyurethane and polyurethane acrylate are water dispersible. In a further embodiment, suitably, the polyurethane is a polyether urethane. Suitably, the formulation may further include a crosslinker, e.g., a water soluble or water dispersible crosslinker. |
