<p>PCT No. PCT/EP95/05013 Sec. 371 Date Aug. 18, 1997 Sec. 102(e) Date Aug. 18, 1997 PCT Filed Dec. 18, 1995 PCT Pub. No. WO96/20796 PCT Pub. Date Jul. 11, 1996The present invention describes a novel coating process that comprises the use of a functional photoinitiator, or a macroinitiator derived therefrom, in a cascade of process steps, wherein, on the one hand, a functional photoinitiator or a macroinitiator derived therefrom is covalently bonded to a carrier and, on the other hand, an oligomer or polymer forming a new surface layer is covalently bonded to the functional photoinitiator, or to the carrier modified by a functional photoinitiator, via functional groups that are co-reactive with isocyanate groups. The invention relates also to novel intermediates that are carriers to which functional photoinitiators that contain free isocyanate groups are bonded.</p> |
