Any remaining water-soluble reactive polymer is removed. The crosslinked polymer is contacted with an aniline reactive composition having aniline monomer and up to 0.5 molar of an aniline oxidizing agent, thereby forming an electrically-conductive polyaniline disposed either within, on top of, or both within and on top of, the crosslinked polymer.

Abstract: A conductive pattern can be formed using a polymeric layer that contains a reactive composition that comprises a reactive polymer that is metal ion-complexing, water-soluble, and crosslinkable. This reactive polymer comprises photosensitive non-aromatic heterocyclic groups each of these groups comprising a carbon-carbon double bond in conjugation with an electron withdrawing group, as well as metal ion-complexing and water solubilizing groups. 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. The resulting electroless seed metal nuclei are electrolessly plated with a suitable metal to form the desired conductive pattern.
