(57) [Problem] To provide excellent adhesion to a substrate after baking, excellent adhesion between layers, curl generation can be suppressed, and a high-resolution conductive circuit pattern can be easily formed on a large area by photolithography technology. In particular, the present invention provides an alkali-developable photocurable conductive paste composition useful for forming a lower electrode circuit of a bus electrode formed on a front substrate of a plasma display panel. SOLUTION: The composition comprises (A) a resin having a carboxyl group, (B) a photopolymerizable monomer, (C) a photopolymerization initiator, (D) a fine powder of synthetic amorphous silica having a silanol group, and (E) a conductive powder. Powder and, if necessary (F) It contains a heat-resistant black pigment, (G) a glass frit and (H) a stabilizer. After applying this photocurable conductive paste composition on a glass substrate of a plasma display panel, Exposure is performed according to a predetermined pattern, development is performed using an alkaline aqueous solution, and baking is performed, whereby a high-definition electrode circuit can be formed. |
