    • 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.
    • 公开了一种相变油墨组合物,其包含着色剂和油墨载体,所述油墨在低于约50℃的温度下为固体,并且在不超过约160℃的喷射温度下显示不超过约20厘泊的粘度 ℃,其中在第一温度下,在油墨载体分子之间存在足够强度的氢键,使得油墨载体形成氢键二聚体,低聚物或聚合物,并且其中在高于第一温度的第二温度下 油墨载体分子之间的氢键被充分破坏,在第二温度下墨中存在较少的氢键二聚体,低聚物或聚合物比在第一温度下存在于墨中的氢键,使得在 第二温度低于第一温度下墨水的粘度。
