Abstract:: Transparent silver ink based on silver amino complex for inkjet printing has been developed. 1,2-diaminopropane, which acts as a solvent and complexing agent, significantly lowered the decomposition temperature of the silver salt and ensured the chemical stability of the resulting ink at room temperature. The annealed films were characterized by close packing and low electrical resistance values (8.5 μOhm·cm at an annealing temperature of 150°C). The ink provides productive inkjet printing while maintaining stable operation of the print head nozzles.
