A low Curing temperature silver ink for use in ink-jet printing and subsequent production of conductive tracks

A drop-on-demand ink-jet printer has been used to print a silver-organic solution onto glass substrates. Conductive silver tracks were obtained by heat treatment of the ink-jet printed deposits at temperatures ranging from 125degreesC-200degreesC in air. Resistivity values were found to have dropped to two to three times the theoretical resisitivity of bulk silver after temperatures of 150degreesC and above were used.
