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.
L'invention concerne des matières de revêtement durcissables par voie thermique et par exposition à un rayonnement actinique, contenant (A) au moins un liant qui comporte des groupes fonctionnels réagissant avec les isocyanates et (B) un composant réticulant qui contient (i) des groupes isocyanates libres et/ou bloqués, (ii) des groupes fonctionnels réactifs, comportant au moins une liaison activable par exposition à un rayonnement actinique, (iii) des segments flexibilisants, qui, en tant que constituants de réseaux tridimensionnels, abaissent leur température de transition vitreuse Tg, et (iv) des segments durcisseurs, qui, en tant que constituants de réseaux tridimensionnels, augmentent leur température de transition vitreuse Tg, à condition que le composant réticulant (B) comporte au moins un constituant présentant les caractéristiques (i) et (ii) ou soit constitué de ce dernier. L'invention concerne également un procédé pour la production de ces matières de revêtement ainsi que l'utilisation de ces dernières.
