An inkjet ink includes: (i) a disazo dye of formula (I): (ii) 1,3-propanediol; (iii) a glycol compound selected from the group consisting of: triethylene glycol and tetraethylene glycol; and (iv) water. The ink has low toxicity and is preferably absent ethylene glycol and sulfolane.

Low toxicity ink formulations with improved printhead lifetime

An inkjet ink includes: (i) a disazo dye of formula (I): (ii) a glycol compound selected from the group consisting of: triethylene glycol, tetraethylene glycol and pentaethylene glycol; and (iv) water.

Ink formulations for improving printhead lifetime

An inkjet ink for improving printhead lifetimes includes: an aqueous-based ink vehicle; a colorant; an anti-kogation additive; and an anti-corrosion additive having at least one acetylenic group, the acetylenic group being absent any tertiary or quaternary &#x3b1;-carbon atoms.

Ink additive combinations for improving printhead lifetime

An inkjet ink includes: (i) a disazo dye of formula (I): (ii) sulfolane; (iii) a glycol compound selected from the group consisting of: ethylene glycol, diethylene glycol, triethylene glycol, tetraethylene glycol and pentaethylene glycol; and (iv) water.
