METAL CATALYTIC COMPOSITIONS AND ARTICLES THEREFROM

摘要

A non-aqueous metal catalytic composition includes: (a) a silver complex comprising reducible silver ions, (b) a silver ion photoreducing composition, (c) a photocurable component, non-curable polymer, or combination of a photocurable component and a non-curable polymer, and (d) nanoparticles of a semi-conducting metal oxide in an amount of at least 0.1 weight %. This composition can be disposed on a substrate, uniformly or in a patternwise fashion. The composition can be dried and then exposed to suitable radiation to reduce the reducible silver ions to silver particles that can then be electrolessly plated with a metal to provide an electrically-conductive article.

1. A non-aqueous metal catalytic composition comprising:
(a) a silver complex comprising reducible silver ions, in an amount of at least 2 weight %, (b) a silver ion photoreducing composition in an amount of at least 1 weight %, (c) a photocurable component, non-curable polymer, or combination of a photocurable component and a non-curable polymer, and (d) nanoparticles of a semi-conducting metal oxide in an amount of at least 0.1 weight %, all amounts being based on the total weight of components (a) through (d).
