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.

Alkali development type photocurable conductive paste composition and

A composition for the formation of barrier ribs of a plasma display panel and a method for the formation of the barrier ribs are disclosed. The formation of barrier ribs is effected by applying either a composition comprising (A) a low-melting glass having a working point of not more than 560.degree. C. , (B) a hydroxyl group-containing polymer having at least two hydroxyl groups per molecule, (C) an inorganic filler, (D) a diluent, and (E) an organosilicic compound possessing in one terminal part thereof an alkoxysilane group having at least two alkoxy groups bonded thereto and in the other terminal part thereof an amine terminal group or a composition comprising (F) a blocked isocyanate compound having isocyanate groups blocked with an amine in addition to the components (A) through (E) mentioned above to a photosensitive film on a substrate so as to fill up grooves formed in the photosensitive film in a prescribed pattern, drying the composition, thermally curing the composition, separating the photosensitive film from the substrate by means of a remover, and subsequently calcining the hardened composition.
