<p>PURPOSE:To obtain the title ink which can give a pattern formation solution of an increased metal content which is useful for the circuit pattern formation of hybrid IC and retains a viscosity suitable for a liquid crystal injector of an ink jet system for a long time, by mixing a metal tert. carboxylate with an organic solvent comprising an aromatic hydrocarbon and an agent for preventing volatilization of a solvent. CONSTITUTION:The title ink is obtained by mixing a metal tert. carboxylate (A) of the formula (wherein R1-3 are each an alkyl, and M1 is a metallic atom.), e.g. silver neodecanoate, with an organic solvent (B) for component A, comprising an aromatic hydrocarbon such as toluene, an agent (C) for preventing volatilization of a solvent, such as alpha-terpineol and, optionally, a component B-soluble organometallic compound (D) other than component A, such as palladium dithiocarbamate or a copper carboxylate. When component D is used, the ink can be improved in a bonding strength to a substrate and wettability with solder and is decreased in resistance to corrosion by solder.</p> |
