u.s. Patent 5,747,117. May 5, 1998 R. Dannenberg, assignor to Servo Corp. of America, Westbury, N. Y.

U.S. Patent 5,747, 166. May 5, 1998 S. Schwarte and H. Grosch, assignors to BASF Corp., SoU1hfie/d, Mich.

A method for forming a pigmented organic coating on a metal surface comprising mixing the following components to form a resin mixture (I) a resin that is an aromatic urethane diacrylate, an aliphatic urethane diacrylate, a polyester tetra-acrylate, or an epoxy acrylate, (2) a photoinitiator, (3) a photosensitizer that is isopropyl thioxanthone, chlorothioxanthone, or thioxanthone; mixing a pigment that is titanium dioxide or a mixture of titanium dioxide and manganese ferrite with the resin mixture to form a spreadable compo-

A method of depositing a film onto a substrate in accordance with a predetermined pattern comprising applying a solution composed of a copolymer dissolved in a solvent; curing and annealing to form a copolymer film on the substrate; depositing a thin metal film onto the copolymer film; removing a portion of the thin metal film corresponding to the predetermined pattern so that the copolymer film is exposed in accordance with the predetermined pattern; removing exposed surfaces of the copolymer film so that the said substrate is exposed in accordance with the predetermined pattern; removing any of the thin metal film remaining on the copolymer film; depositing a film onto the substrate

A method of improving the popping limit of an aqueous coating comprising a water-thinnable, hydroxyl-containing polyacrylate resin wherein the popping limit is improved by adding a blocked polyisocyanate or a mixture of blocked polyisocyanates to the coating in an amount so that the ratio between the OR equivalents and NCO equivalents is between 1.0:0.7 and 1.0:1.2.

contammg effect-pigments; drying at a temperature of 20 to 80·C down to a residual content of 3 to 20% by weight of volatile fractions; applying a third coating layer by overcoating the second coating layer wet-on-wet with a liquid clear lacquer; and jointly drying or hardening the three coating layers at temperatures of 60 to 1,100T.
