Title:

SILVER MOLECULAR INK WITH LOW VISCOSITY AND LOW PROCESSING TEMPERATURE

Document Type and Number:

WIPO Patent Application WO/2018/146619

Kind Code:

A3

Abstract:

A molecular ink contains: a silver carboxylate; and a polymeric binder comprising a polyester, polyimide, polyether imide or any mixture thereof having functional groups that render the polymeric binder compatible with the organic amine. Such an ink may have higher silver loading, lower viscosity and lower processing temperatures than existing silver inks.
