rial; said metal plating step involving the substeps of electroless plating a first metal layer on the substrate and electroplating a second metal layer on the first metal layer.
Oxygen-Curable Coating Composition
C o m p o s i t e Plated A r t i c l e U.S. Patent 5,702,763. Dec. 30, 1977 N. Feldstein, assignor to Surface Technology Inc., Trenton, N.J.
A liquid coating composition comprising, on a weight basis, 15 to 60 parts of a free-radical reactive acrylate monomer; 5 to 25 parts of an air-curing polyether-ene polymer containing at least three activated double bonds per molecule; a catalytic amount of photoiniatiator; and a catalytic amount of a dissolved transition metal ion, said composition being free from acrylated carbonate polymers, added active oxygen catalytic compounds, oxygen-reaction inhibitors, and inert solvents.
A process for plating a substrate to form a composite plated coating comprising contacting with 'a plating composition incorporating particulate matter insoluble with the plating composition to yield a compositeplated coating with particulate matter dispersed within the coating having a predeterrnined varied density of codeposited particulate matter from a first region to a second region.

UV-Curable Coatings
Coated Abrasive U.S. Patent5,702,811. Dec. 30, 1997 K-L. Ho and W.L Harmer, St. Paul, Minn.
U.S. Patent 5,703,141. Dec. 30, 1997 P. Jin, assignor to Tarkett AG, Frankenthal, Germany
A coated abrasive article comprising a backing having a layer of grains adherently bonded thereto by a binding material, wherein the layer of grains comprises abrasive grains and nonabrasive composite grains.
A UV-curable composition having a low viscosity and useful in the preparation of coatings having high tensile strength, high elongation, and high gloss retention, prepared by reacting a caprolactone adduct and an isocyanate in a first reaction,
wherein the product of the first reaction is further reacted with a hydroxyalkyl acrylate or mcthacrylate and an additional caprolactone adduct component, while the ratio of acrylate or methacrylate to caprolactone adduct is adjusted in order to vary the hardness an flexibility of the composition as desired.
Waterborne Coating U.S. Patent5,703,155. Dec. 30, 1997 S. Swarup and R.J. Sadvary, assignors to PPG Industries Inc., Pittsburgh
A waterborne coating composition having improved rheology control and appearance comprising a polymeric film-forming resin; up to 2.1% by weight of a hydrophobic amorphous fumed silica; and 0.5 to 4.0% of a nongelled copolymer.
Radiation-Curable Powder Paint U.S. Patent 5,703,198. Dec. 30, 1997 F. Twigt nd R. van der Linde, assignors to DSM N. V., Heerlen, Netherlands
A powder paint containing a radiationcurable binder composition.
