Beschreibung
Zusammenfassung:	A photo-curable, electrically conductive composition comprising (A) black, electrically conductive particles having a relative surface area more than 20 m /g, (B) an organic binder, (C) a photopolymerizable monomer and (D) a photopolymerization initiator is the essential feature of the composition of the invention, and a second embodiment is a composition which further comprises (E) inorganic particles. Such a photo-curable conductive composition is applied on transparent electrodes (3a, 3b) of a front glass substrate (1), is exposed to a light according to a predetermined pattern, is developed and burned, to thereby form a lower layer (black layer) electrode circuit of bus electrodes (4a, 4b). The composition can be used for forming a lower layer (black layer) electrode circuit which provides satisfactory conductivity and blackness at the same time in the formation of an electrode on a front substrate of a plasma display panel (PDP). L'invention porte sur une composition photodurcissable électroconductrice comportant: (A) des particules noires électroconductrices présentant une surface relative de plus de 20 m /g, (B) un liant organique, (C) un monomère photopolymérisable, (D) un amorceur de photopolymérisation représentant le trait essentiel de l'invention, et dans une variante (E) des particules minérales. Ladite composition appliquée sur des électrodes transparentes (3a, 3b) du substrat d'un verre frontal (1) est soumise à un rayonnement lumineux d'une nature déterminée, puis développée et calcinée pour former un circuit d'électrodes de bus à couche inférieure (couche noire) présentant à la fois une conductivité électrique et une noirceur satisfaisantes pour constituer une électrode sur le panneau frontal d'un écran à plasma.
