Abstract
Official abstract text for this publication.
Stable zero-valent metal compositions and methods of making and using these compositions are provided. Such compositions are useful as catalysts for subsequent metallization of non-conductive substrates, and are particularly useful in the manufacture of electronic devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: (a) providing a substrate having a plurality of through-holes; (b) applying a composition comprising 0.5 to 100 ppm of a zero-valent metal, a stabilizer compound and water; wherein the zero-valent metal is selected from the group consisting of palladium, silver, cobalt, nickel, gold, copper and ruthenium; wherein the stabilizer compound is a compound of formula (I) or formula (II)…
