Abstract
A photopolymerizable composition has five essential components: (a) a photopolymerizable epoxy material, (b) a photoacid generator such as an onium salt, (c) electron donor photosensitizer having an oxidation potential of at least 0.4 V and up to and including 3 V vs. SCE, and (d) metal particles. This photopolymerizable composition can be applied or printed onto one or both sides of various substrates to form articles that can be used to form electrically conductive materials. Methods for using the photopolymerizable compositions include electroless plating methods that can be carried out in roll-to-roll printing systems once various photocured patterns are formed from the photopolymerizable compositions.
