  • Phase change ink compositions
    Patent number: 6906118
    Abstract: Disclosed is 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.
    Type: Grant
