  • Coating composition and a process for manufacturing the same
    Patent number: 5091009
    Abstract: A coating composition for forming an inorganic film on a glass, ceramic metal or plastic surface is obtained by hydrolyzing and condensing a metal alkoxide of the general formula:M(OR).sub.nwherein M represents a metal atom, R represents an alkyl group having 1 to 5 carbon atoms, and n represents the valence number of M in an organic solvent in the presence of an aluminum salt; and adding a deposition inhibitor which prevents the separation of the aluminum salt when a film is formed. A process for preparing the composition is also disclosed.

  • Formation of catalytic metal nuclei for electroless plating
    Patent number: 4830880
    Abstract: An electroless plating method which comprises applying to a substrate a polymer composition comprising 100 parts by weight of a polymer and an organic metal complex in an amount of from 0.001 to 50 parts by weight as metal, pyrolytically decomposing the organic metal complex at a temperature of from 50.degree. to 500.degree. C. to form plating catalyst metal nuclei on the substrate, removing the dried polymer coating, and conducting electroless plating of the substrate.
