Title (EN) UV CURABLE ADHESION PROMOTERS BASED ON FUNCTIONALISED POLYVINYL ALCOHOLS
(FR) PROMOTEURS D'ADHÉRENCE DURCISSABLES PAR UV À BASE D'ALCOOLS POLYVINYLIQUES FONCTIONNALISÉS
Abstract:
(EN) Suggested are new adhesion promoters,which are particular suitable for use in displays. Its inclusion in the polymerisable LC mixture results in an excellent adhesion on substrate without colouration over time i.e. compared to aminosiloxanes. The new additives have no effect on alignment of LC on the substrate while improving the adhesion.
(FR) L'invention concerne de nouveaux promoteurs d'adhérence, qui sont particulièrement appropriés pour une utilisation dans des écrans d'affichage. Son inclusion dans le mélange de cristaux liquides polymérisables permet d'obtenir une excellente adhérence sur le substrat sans coloration dans le temps, c'est-à-dire comparés aux aminosiloxanes. Les nouveaux additifs n'ont pas d'effet sur l'alignement de cristaux liquides sur le substrat tout en améliorant l'adhérence.
