Patent ID: 8764960

Claim:
A method of manufacturing a metal clad laminate comprising the steps of: (i) forming a conductive layer on a material by coating a silver coating composition comprising silver complexes which are formed by a reaction between a silver compound of Formula 1, and an ammonium carbamate compound of Formula 2, an ammonium carbonate compound of Formula 3, or an ammonium bicarbonate compound of Formula 4; and (ii) forming a metal-plated layer by electroplating metals on said conductive layer: in the formula above, X is a substituted group selected from the group consisting of oxygen, sulfur, halogen, cyano, cyanate, carbonate, nitrate, nitrite, sulfate, phosphate, thiocyanate, chlorate, perchlorate, tetrafluoro borate, acetylacetonate, carboxylate and their derivatives, n is an integer of 1 to 4, R 1 to R 6 are independently selected from the group consisting of hydrogen, C 1 -C 30 aliphatic or cycloaliphatic alkyl, aryl or aralkyl group, a substituted alkyl or aryl group, a heterocyclic compound, a polymer compound, and derivatives thereof, wherein at least one of R 1 to R 6 is independently selected from C 1 -C 30 aliphatic or cycloaliphatic alkyl, aryl or aralkyl group, a substituted alkyl or aryl group, a heterocyclic compound, a polymer compound, and derivatives thereof.
