Abstract: A conductive pattern can be formed using a polymeric layer that contains a reactive composition having a reactive polymer. This reactive polymer comprises (i) a backbone, and (ii) pendant photosensitive non-aromatic unsaturated heterocyclic groups comprising an amide group that is conjugated with a carbon-carbon double bond. The non-aromatic unsaturated heterocyclic groups are linked to the backbone at an amide nitrogen atom. The reactive composition can be patternwise exposed to suitable radiation to induce crosslinking within the reactive polymer. The reactive composition and reactive polymer in the non-exposed regions can be removed due to their aqueous solubility, but the exposed regions of the polymeric layer are contacted with electroless seed metal ions, which are then reduced, followed by electrolessly plating with a suitable metal to form the desired conductive pattern. Various articles can be prepared during this process, and the product article can be incorporated into various electronic devices.
