PURPOSE: To obtain the subject composition comprising a specific reaction product, a diluent, a photopolymerization initiator and conductor powder, excellent in developing properties in formation of a circuit pattern by ultraviolet rays and in pattern accuracy after development, low in the resistance value of the circuit pattern and excellent in adhesivity. CONSTITUTION: This conductor paste composition comprises (A) a reaction product of a copolymer of styrene and maleic anhydride and an OH-containing mono(meth)acrylate such as 2-hydroxyethyl (meth)acrylate, 2-hydroxypropyl (meth) acrylate, etc., (B) a diluent such as ethyl (meth)acrylate, an (α-alkyl) styrene, etc., (C) a photopolymerization initiator such as 2,4-diethylthioxanthone, benzyldimethylketal, etc., and (D) conductor powder such as copper powder, silver powder, palladium powder, etc. |
