There is provided a photo-curable, electrically conductive composition which is capable of forming a lower layer (black layer) electrode circuit satisfying both the sufficient conductivity and blackness after calcination in the formation of an electrode on a front substrate of a plasma display panel (PDP). The composition comprises, in the first fundamental mode thereof, (A) electrically conductive black fine particles having a specific surface area of more than 20 m2/g,(B) anorganic binder, (C) a photopolymerizable monomer, and (D) a photopolymerization initiator, and in the second mode further comprises (E) inorganic fine particles besides the above components. The lower layer (black layer) electrode circuit of bus electrodes (4a, 4b) of the PDP is formed by applying such a photo-curable, electrically conductive composition on transparent electrodes (3a, 3b) of a front glass substrate (1), exposing the applied layer to light according to a predetermined pattern, and subjecting the layer to development and calcination.
A photo-curable, electrically conductive composition, comprising (A) electrically conductive black particles having a specific surface area of more than 20 m2/g and not more than 100 m2/g, said electrically conductive black particles being at least one species selected from the group consisting of ruthenium oxides, ruthenium compounds, CuO—Cr2O3, CuO—Cr2O3—Mn2O3, CuO—Fe2O3, CuO—Fe2O3—Mn2O3, and CuO—Fe2O3—Mn2O3—Al2O3, (B) a carboxyl group-containing resin as an organic binder, (C) a photopolymerizable monomer having a (meth)acryloyl group in its molecule, and (D) a photopolymerization initiator.
The composition set forth in claim 5, wherein said resin is at least one resin having a carboxyl group selected from the group consisting of:
