摘要:
The present invention is directed to an improved method for metallizing polymer substrates, such as polyimides. The present invention comprises the steps of surface treating the polymer substrate with a plasma jet or corona discharge surface treatment, conditioning and etching the polymer substrate with an etching solution comprising a hydroxide and ionic palladium, activating the polymer substrate with ionic palladium, reducing the palladium on the polymer substrate, plating an electroless nickel layer onto the prepared polymer substrate, and plating an electroless copper layer over the electroless nickel layer. The process of the invention provides an improved method for preparing the polymer substrate for subsequent electrolytic plating thereon.

The present invention relates to methods for tagging an ink with a detectable marker and methods for identifying an ink. The tagged ink includes a colorant visible under visible light and a detectable marker capable of fluorescing when subjected to infrared light. A method for identifying an ink includes obtaining a sample of an unidentified ink, subjecting the sample to infrared light such that a detectable marker, if present, fluoresces, and determining whether any fluorescence emitted from the sample corresponds to fluorescence from a tagged ink. A system for identifying an unidentified ink is also disclosed.
