Abstract
Silver carbonate decomposes to form silver metal by a temperature of 280 degrees Celsius. Its use in inkjet ink allows the low-cost production of conductive metallic inks. The silver metal layer could be further processed to enhance silver decorative properties and in particular light reflective properties
Claims27
A method comprising:
- depositing on surface of a substrate a layer of ink the ink containing at least silver carbonate particles;
- and
- firing the substrate at a temperature and time sufficient to change at least the conductivity of the layer of ink.
An ink composition comprising prior to firing at least 20% of silver carbonate and at least 14% of metal silver after the firing.
An ink composition comprising:
- 20% to 80% of silver carbonate
- 0.5% to 10% of dispersant;
- 20% to 70% of vehicle;
- 0.5% to 5% of binder;
- and
- 0.05% to 2.0% of other additives.
