Abstract
A method for forming a metal pattern on a substrate via printing and electroless plating is disclosed, which includes printing a pattern on the substrate with an ink composition, drying the printed pattern, and contacting the dried pattern with an electroless plating solution. The ink composition either contains components (i), (ii) and (iii), components (i) and (iv), or components (i) and (v), which are dissolved or dispersed in a solvent, wherein (i) is a binder; (ii) is a sulfate terminated polymer of an ethylenically unsaturated monomer; (iii) is a catalytic metal precursor; (iv) is a polymer of an ethylenically unsaturated monomer deposited with particles of catalytic metal; and (v) is a copolymer of an ethylenically unsaturated monomer and a hydrophilic monomer deposited with particles of catalytic metal. The binder (i) is a water swellable resin. The catalytic metal may be Au, Ag, Pd, Pt or Ru.
