ABSTRACT:
Disclosed are an alkali development type photocurable conductive paste composition and a plasma display panel having electrodes thereof formed of the composition. The conductive paste composition comprises (A) a copolymer resin resulting from the addition of glycidyl (meth)acrylate to a copolymer of methyl methacrylate with (meth)acrylic acid, (B) a photopolymerization initiator, (C) a photopolymerizable monomer, (D) a powder of at least one conductive metal selected from the group consisting of Au, Ag, Ni, and Al, (E) glass frit, and (F) an acidic phosphorus compound. A fine electrode circuit can be formed on a substrate to be used in the plasma display panel by applying the composition on the substrate, exposing the applied layer to radiation according a prescribed pattern, developing the coating film of the composition with an aqueous alkali solution, and calcining the developed coating film.
