Phase change inks containing curable trans-1,2-cyclohexane bis(urea-urethane) compounds

摘要

Phase change inks comprising a phase change ink carrier and one or more curable trans-1,2-cyclohexane bis[urea-urethane] compounds of the formulae wherein R₁ and R'₁ are alkylene, arylene, arylalkylene, or alkylarylene groups, R₂ and R'₂ are alkyl, aryl, arylalkyl, or alkylaryl groups, R₃ and R'₃ are hydrogen atoms or alkyl groups, R₄ and R'₄ are hydrogen atoms, fluorine atoms, alkyl groups, or phenyl groups, n is an integer of 0, 1, 2, 3, or 4, and R₅ is an alkyl, aryl, arylalkyl, or alkylaryl group, or a substituent other than an alkyl, aryl, arylalkyl, or alkylaryl group, provided that at least one of R₁, R'₁, R₂, R'₂, R₃, R'₃, R₄, R'₄, or one or more of R₅ is an alkyl, alkylene, arylalkyl, arylalkylene, alkylaryl, or alkylarylene group containing an ethylenic unsaturation rendering the compound curable upon exposure to heat and/or actinic radiation.
