Abstract: A catalyst precursor resin composition includes an organic polymer resin; a fluorinated-organic complex of silver ion; a monomer having multifunctional ethylene-unsaturated bonds; a photoinitiator; and an organic solvent. The metallic pattern is formed by forming catalyst pattern on a base using the catalyst precursor resin composition reducing the formed catalyst pattern, and electroless plating the reduced catalyst pattern. In the case of forming metallic pattern using the catalyst precursor resin composition, a compatibility of catalyst is good enough not to make precipitation, chemical resistance and adhesive force of the formed catalyst layer are good, catalyst loss is reduced during wet process such as development or plating process, depositing speed is improved, and thus a metallic pattern having good homogeneous and micro pattern property may be formed after electroless plating.
