| 摘要 |
<p>The invention relates to a curable aqueous polyurethane dispersion that substantially consists of a) at least one compound that has two free isocyanate groups, at least one allophanate group and at least one radically polymerizable C=C double bond, a carbonyl group or an oxygen atom in ether function being directly bound to the double bond, b) at least one compound that has at least one isocyanate reactive group and one radically polymerizable C=C double bond, c) optionally at least one compound that has at least one isocyanate reactive group and at least one acidic group, e) at least one alkaline compound that neutralizes or partially neutralizes the acidic groups of compound d), and a thermal initiator. The invention also relates to the use of these dispersions for coating substrates.</p> |
