  • Patent number: 10059821
    Abstract: A method is used to provide an electrically-conductive polyaniline pattern by providing a uniform layer of a photocurable composition on a substrate. The photocurable composition comprises a water-soluble reactive polymer comprising (a) greater than 40 mol % of recurring units comprising sulfonic acid or sulfonate groups, and (b) at least 5 mol % of recurring units comprising a pendant group capable of crosslinking via [2+2] photocycloaddition. The photocurable composition is exposed to cause crosslinking via [2+2] photocycloaddition of the (b) recurring units, thereby forming a crosslinked polymer. 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.

  • Patent number: 9360759
    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.
