FORMING SILVER CATALYTIC SITES FROM SILVER PHOSPHITE CARBOXYLATES

摘要

A non-aqueous metal catalytic composition includes (a) a silver carboxylate-trialkyl(triaryl)phosphite 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 %, and (c) a photocurable component or a non-curable polymer or a combination of a photocurable component and a non-curable polymer. This non-aqueous metal catalytic composition can be used to form silver metal particles in situ during suitable reducing conditions. The silver metal can be provided in a suitable layer or pattern on a substrate, which can then be subsequently subjected to electroless plating to form electrically-conductive layers or patterns for use in various articles or as touch screen displays in electronic devices.
