Marbelizing Process u.& Patent 5,639,513. June 17, 1997 E. Latham, Reisterstown, Md,

In a method for coating a surface of an object with a design, comprising floating a plurality of different colored oil-based paints on a surface of a water conditioned by the addition of a conditioning agent in sufficient amount so that the paints spread in a thin layer floating on the surface of the water containing the conditioning agent, dipping an object into the conditioned wa- ter having the thin layer of paints floating on the surface so that the object contacts the thin layer of paints floating on the surface, removing the object from the wa- ter, and drying to form a coated object that maintains the design, the improvement wherein the conditioning agent is cream of tartar.

A method of producing an article with a color-plus-clear composite coating wherein

the flexible clear coating composition com- prises a first component having appended thereto more than one carbamate functional group, and a second component comprising a compound reactive with the carbamate groups, which is a functionalized acryla- mide.

Multilayer Coated Article u.s. Patent 5,639,564. June 17, 1997 S.R. Moysan, I/I and R.W. Sugg, assignors to Baldwin Hardware Corp., Reading, Pa.

An article comprising a metallic sub- strate having disposed on at least a portion of its surface a multilayer brass-colored coating consisting essentially of a layer of semibright nickel; a layer of bright nickel; a layer of palladium-nickel alloy; a layer of zirconium; and a top layer comprised of zirconium compound.

Temporary Coating Capable of Low Temperature Drying u.s. Patent 5,639,614. June 17, 1997 E.J. Van Buskirk and Ft. Mask& assignors to PPG Industries Inc., Pittsburgh
