Abstract: The present disclosure relates to magenta inkjet inks having a quinacridone pigment and an azo pigment. The azo pigment has at least one azo compound having the formula (I), in which Ra is selected from H, aryl and C1 to C4 alkyl, and Rb, Rc and Rd are each independently selected from H, a C1 to C4 alkyl, an oxygen-containing, a nitrogen-containing and a sulphur-containing functional group. Where Ra is aryl, the aryl is not a phenyl group having at least one hydrogen atom that has been substituted with a chlorine atom.
