Electroplating Process U.S. Patent 5,626,736. May 6, 1997 SM. Florio et al. assignors to Ship/ey Co. L.L.C., Marlborough, Mass.

A process for depositing metal on the walls of openings passing through a cop-

per-clad nonmetallic planar substrate com- prising forming a sacrificial coating over the copper cladding, without removing the sacrificial coating. providing a dispersion

of carbonaceous particles in an aqueous medium and contacting the substrate hav- ing the openings with the dispersion to

form a porous coating of the carbonaceous dispersion over the surfaces, of the suhstrate including the sacrificial cclating over the

copper cladding, removing the carhon- aceous coating from the copper cladding hy contacting with an etchant that dissolves

the sacrificial coating preff:rentially to the copper cladding. and plating Imetal on at least those portions of the :,ubstrate coated with the carbonaceous coating from an

electrolytic metal plating sl.)lution.

A process for the multilayer coating of a

substrate by applying a base layer of an aqueous coating composition onto an op-

tionally precoated substrate and suhse- quently overcoating with ;I clear coating characterized in that the clear coating used

contains at least one copolymer containing hydroxyl groups, one or more polyisocy;u- ates, and one or more solvc:nts
