The present disclosure provides an ink jet ink comprising a dye, a vehicle, and a surfactant combination comprising: (a) an acetylene alcohol having the generic structure: wherein R and R1 are C1-C10 linear or branched alkyl groups or hydrogen, and wherein only one hydrogen on either R or R1 is replaced by a hydroxy group; and (b) a siloxane surfactant having the generalized structure wherein E is —CH3 or —O—Si(CH3)3, G=—CH2—, or —CH2—CH2—CH2—, x, y, and z are independently about 0 to about 40, and y+z is at least 1; and wherein the acetylene alcohol is present in the amount of at least about 0.3%, and the siloxane surfactant is present in the amount of at least about 0.03 to about 0.5 percent, based on the weight of the ink composition. The inks provide good color on a range of media and can be loaded into used inkjet pens without volume reduction.
