A UV curable composition comprising a UV curable epoxy-functional essentially solver: fee reactant, a UV curing agent. In certain embodiments, the composition also may comprise a conductive filler, which may be present at a selected concentration, particle size distribution and shape, wherein said composition, subsequent to cure, provides a deposited conductive film whose conductivity is controlled by said conductive filler concentration, particle size distribution and shape. L'invention porte sur une composition UV-durcissable comportant un réactif UV-durcissable à fonction époxy quasiment exempt de solvant et un durcisseur sensible à l'UV. Dans certaines exécutions la composition peut également comporter une charge conductrice dont la concentration et la distribution en taille et la forme des particules sont sélectionnés. Une fois durcie ladite composition fournit un film conducteur dont la conductivité dépend de la concentration de la charge et de la distribution en taille et de la forme de ses particules.
