Summary: | A method of ejecting ink from a thermal inkjet printhead. The method includes the steps of: (i) supplying an ink to at least one nozzle chamber of the printhead; and (ii) actuating a heater element in the nozzle chamber and heating the ink to a temperature sufficient to form a bubble therein, thereby causing the ink to be ejected from a nozzle opening associated with the nozzle chamber. The ink is a solvent-based ink composition including: (a) 20-80 wt. % of a compound of formula (A); wherein: R1 is C1-6 alkyl; and each of R2, R3 and R4 is independently selected from H, C1-6 alkyl, halogen, OH, and C1-6 alkoxy; (b) 10-70 wt. % of a C1-6 alcohol; and (c) 0.01-25 wt. % of a colorant. |
