Abstract
A method of producing an article is described. The method includes (a) providing a substrate comprising an etchable surface layer; (b) coating the etchable surface layer with a composition comprising a non-volatile, etch-resistant component in a volatile liquid carrier; and (c) drying the composition to remove the liquid carrier, whereupon the non-volatile, etch-resistant component self-assembles to form etch-resistant traces on the etchable surface layer. The liquid carrier is in the form of an emulsion comprising a continuous phase and a second phase in the form of domains dispersed in the continuous phase.

A method of producing an article comprising:
- (a) providing a substrate comprising a metallized surface layer;
- (b) coating the metallized surface layer with a composition comprising a non-volatile, etch-resistant component in a volatile liquid carrier,
- wherein the composition is essentially free of nanoparticles and the liquid carrier is in the form of an emulsion comprising aqueous domains dispersed in a continuous phase comprising an organic solvent that evaporates more quickly than the aqueous domains;
- wherein the non-volatile, etch-resistant component is selected from the group consisting of Novolac resins, epoxy resins, polyester polyols, alkanes having at least 15 carbon atoms, and combinations thereof;
- wherein the composition further comprises an etching agent;
- (c) drying the composition to remove the liquid carrier, whereupon the non-volatile, etch-resistant component self-assembles to form interconnected etch-resistant traces on the metallized surface layer defining randomly shaped cells and the etching agent etches areas of the metallized surface layer not covered by the etch-resistant traces to expose the underlying substrate.
