Abstract
The present disclosure provides an ink jet ink including a dye, a vehicle, and a surfactant combination having: (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, provided that E is —CH3 when x is greater than 0; EO is ethylene oxide, PO is propylene oxide, G=-CH2—, or —CH2—CH2—CH2—, x, y, and z are independently about 0 to about 40, 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.
