ABSTRACT:
CROSS-REFERENCE IS MADE TO THE FOLLOWING APPLICATIONS
Application U.S. Ser. No. 09/949,315, filed Sep. 7, 2001, U.S. Publication No. 20030079644, entitled “Aqueous Ink Compositions,” with the named inventors Thomas W. Smith, David J. Luca, and Kathleen M. McGrane, the disclosure of which is totally incorporated herein by reference, discloses an aqueous ink composition comprising an aqueous liquid vehicle, a colorant, and an additive wherein, when the ink has been applied to a recording substrate in an image pattern and a substantial amount of the aqueous liquid vehicle has either evaporated from the ink image, hydrogen bonds of sufficient strength exist between the additive molecules so that the additive forms hydrogen-bonded oligomers or polymers.
Application U.S. Ser. No. 09/948,958, filed Sep. 7, 2001, U.S. Publication No. 20030105185, entitled “Phase Change Ink Compositions,” with the named inventors H. Bruce Goodbrand, Thomas W. Smith, Dina Popovic, Daniel A. Foucher, and Kathleen M. McGrane, the disclosure of which is totally incorporated herein by reference, discloses a phase change ink composition comprising a colorant and an ink vehicle, the ink being a solid at temperatures less than about 50° C. and exhibiting a viscosity of no more than about 20 centipoise at a jetting temperature of no more than about 160° C., wherein at a first temperature hydrogen bonds of sufficient strength exist between the ink vehicle molecules so that the ink vehicle forms hydrogen-bonded dimers, oligomers, or polymers, and wherein at a second temperature which is higher than the first temperature the hydrogen bonds between the ink vehicle molecules are sufficiently broken that fewer hydrogen-bonded dimers, oligomers, or polymers are present in the ink at the second temperature than are present in the ink at the first temperature, so that the viscosity of the ink at the second temperature is lower than the viscosity of the ink at the first temperature.
