Patent ID: 7378478

Claim:
A method comprising: irradiating a catalyst precursor composition with UV irradiation, wherein the catalyst precursor composition comprises: (a) a reactive oligomer which has acrylate or methacrylate as a functional group, and a molecular weight ranging from 500 to 5000; (b) a reactive monomer which has acrylate or methacrylate as a functional group, and a molecular weight ranging from 100 to 600; (c) α-hydroxyketone as a photoinitiator; (d) a catalyst precursor for electroless plating which is an organic compound or an inorganic compound including a group VIII B metal or a group I B metal; and (e) a solvent selected from the group consisting of chloroform, acetonitrile, methylethylketone, ethylacetate, and mixtures thereof; and reducing the metal of the catalyst precursor organic compound or inorganic compound to form a catalyst for electroless plating.
