Abstract
A method of improving conductivity of a metal pattern (18) includes providing a developed silver pattern (14) formed from a photographic silver salt provided in a binder coated on a substrate (12); and selectively heating the silver pattern with electromagnetic radiation.
Claims13
A method of improving conductivity of a metal pattern comprising:
- providing a developed silver pattern formed from a photographic silver salt provided in a binder coated on a substrate;
- and
- increasing conductivity of the silver pattern by heating the silver pattern with electromagnetic radiation to anneal the silver pattern.
A method of making a conductive metal pattern comprising:
- coating a silver salt in a binder on a substrate;
- imaging the silver salt and binder to produce a silver pattern;
- developing the silver pattern;
- and
- annealing the silver pattern by exposing the silver pattern with electromagnetic radiation to increase the conductivity of the silver pattern.

A method of making a capacitive touchscreen comprising:
- providing a substrate;
- coating a silver salt in a binder on a first side of the substrate;
- coating a silver salt in a binder on a second side of the substrate;
- imaging the silver salt and binder on the first side of the substrate to produce a first silver pattern;
- imaging the silver salt and binder on the second side of the substrate on the second side of the substrate to produce a second silver pattern;
- developing the first and second silver pattern;
- and
- heating the first and second silver patterns with electromagnetic radiation to remove binder in the vicinity of the silver pattern and increase conductivity of the silver pattern.
