-48. (canceled)
A process for forming a metal nanowire pattern on a surface region of a substrate, the process comprising:
- (a) applying on at least one surface region of a substrate a solution comprising metal seeds;
- (b) applying a growth solution;
- and
- (c) allowing formation of a metal nanowire pattern in a region where both the solution comprising metal seeds and the growth solution have been applied.

An ink-jet printing process for forming a metal nanowire pattern on a surface region of a substrate, the process comprising:
- (a) forming by ink-jet printing a pattern on at least one surface region of a substrate, the pattern being of:
- an ink formulation comprising metal seeds;
- (b) forming by ink-jet printing a pattern of a formulation comprising at least one metal precursor and at least one reducing agent onto the pattern of step (a);
- and
- (c) allowing said patterns to form into a metal nanowire pattern.
