[PROBLEMS] To form a high-resolution conductive circuit pattern over a large area easily by photolithography technology without any problems such as warpage and line width shrinkage after firing, and particularly to form an electrode circuit of a plasma display panel. The present invention provides an alkali-developable photocurable conductive paste composition useful for the present invention. SOLUTION: The composition comprises (A) an acrylic copolymer having a carboxyl group and an ethylenically unsaturated group, (B) a photopolymerizable monomer, (C) a photopolymerization initiator, (D) a titanocene derivative, E) It contains a conductive metal powder and, if necessary, (F) a glass frit. After applying the photocurable conductive paste composition on a glass substrate of a plasma display panel, exposure is performed according to a predetermined pattern, developed with an alkaline aqueous solution, and then baked, A high-definition electrode circuit can be formed. |
