Abstract
Abstract A moulded article being at least partially provided with a metal coating of good adhesive power comprising a hardened product of a moulding composition comprising (a) a mixed condensate of a phenoplast-forming phenol, an aminoplast forming compound and formaldehyde, or (b) a mixture of a phenol formaldehyde condensate with a condensate of formaldehyde with an aminoplast forming compound or (c) a mixture of (a) and (b) and in which moulding composition the molar ratio of phenol to aminoplast forming compound is from 1:0,05 to 1:20, the said metal coating being formed in at least two steps, which moulded article is suitable as a printed circuit.
