  • Patent number: 8840769
    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.

  • Publication number: 20140249288
    Abstract: A method of preparing an organopolysiloxane is provided. An organopolysiloxane, which has both a linear or cross-linking structure derived from a trifunctional siloxane unit and a linear structure derived from a difunctional siloxane unit among the molecular structures and also has a sufficiently long linear structure, can be effectively prepared. Also, the organopolysiloxane can be synthesized so that it can have a sufficiently high molecular weight, and a target product showing excellent physical properties can be effectively prepared by minimizing a ratio of a functional group such as an alkoxy group or a hydroxyl group in the synthesized organopolysiloxane.
