A method of ejecting ink from a thermal inkjet printhead. The method comprises 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 comprising: (a) 20-80 wt. % of a compound of formula (D); wherein: each of R8 and R9 is independently selected from a C1-12 alkyl group interrupted with 0, 1, 2 or 3 oxygen atoms; or R8 and R9 are together joined to form a C3-12 cycloalkylene group; (b) 10-70 wt. % of a C1-6 alcohol; and (c) 0.01-25 wt. % of a colorant.
