| 摘要 |
<p>The invention relates to coating materials which can be cured thermally and by means of actinic radiation, comprising: (A) at least one binding agent containing isocyanate-reactive functional groups and (B) a cross-linking agent component containing (i) free and/or blocked isocyanate groups, (ii) reactive functional groups containing at least one bond which can be activated by actinic radiation, (iii) flexible segments which, as a constituent of three-dimensional networks, lower their glass transition temperature Tg, and (iv) curing segments which, as a constituent of three-dimensional networks, increase their glass transition temperature Tg, provided that the cross-linking agent component (B) comprises at least one constituent having the characteristics (i) and (ii) or consists thereof. The invention also relates to a method for producing said coating materials and the use thereof.</p> |
