摘要： A process for treating metal surfaces that includes first contacting the metal surface with a particular acidic peroxide adhesion promoting composition, followed by contacting that metal surface with an aqueous acid post-dip composition to provide a micro-roughened surface. This treatment is particularly suitable for treating metal surfaces used in printed circuit multilayer construction.

摘要： The invention relates to a protective U.V. curable or photoimageable cover layer for an optical disk substrate and a method of applying the protective cover layer to an optical substrate. The U.V. curable or photoimageable layer is applied as a dry film and has high clarity and cures to a flexible, scratch resistant, non-shrinking film, which has good adhesion to the underlying substrate.

摘要： A method of treating a substrate, wherein the substrate comprises a layer deposited from a trivalent chromium electrolyte, is described. The method includes the steps of providing an anode and the chromium(III) plated substrate as a cathode in an electrolyte comprising (i) a trivalent chromium salt; and (ii) a complexant; and passing an electrical current between the anode and the cathode to passivate the chromium(III) plated substrate. The substrate may be first plated with a plated nickel layer so that the chromium(III) plated layer is deposited over the nickel plated layer.

摘要： A method of preparing a solution capable of etching a platable plastic. The method comprises the steps of: (a) providing an electrolyte comprising a solution of manganese(II) in a solution of 9 to 15 molar sulfuric acid or phosphoric acid to an electrolytic cell; (b) applying a current to the electrolytic cell, wherein the electrolytic cell comprises an anode and a cathode; and (c) oxidizing the electrolyte to form manganese(III) ions, wherein the manganese(III) ions form a metastable sulfate complex. Thereafter, a platable plastic may be immersed in the metastable sulfate complex for a period of time to etch the platable substrate prior to subsequent plating steps.

摘要： A process of making a polymeric phenazonium compound having the general formula: wherein R1, R2, R4, R5, R6, R8 and R9 are the same or different, and represent hydrogen, a low alkyl or a substituted aryl, R3 starts with NH2 and is diazotized followed by polymerization, R5 and R8 may alternatively represent monomeric or polymeric phenazonium radicals, R7 with its substituent group is a substituted amine, with RX and RY representing any combination of CH3, C2H5, and hydrogen, except that RX and RY cannot both be hydrogen, A is an acid radical, and n is an integer from 2 to 100, preferably from 2 to 20 is described. The polymeric phenazonium compound is usable in as an additive in a metal plating bath. The method includes the steps of: a) dissolving an effective amount of an amino compound in a formic acid solution; b) adding a nitrite salt to diazotize the amino compound; and c) adding sulfamic acid to neutralize any excess nitrous acid that may be formed in step b), whereby a polymeric phenazonium compound is produced.
