Patent number: 7317122
Abstract: Curable trans-1,2-cyclohexane bis(urea-urethane) compounds of the formulae wherein R1 and R?1 each, independently of the other, are alkylene, arylene, arylalkylene, or alkylarylene groups, R2 and R?2 each, independently of the other, are alkyl, aryl, arylalkyl, or alkylaryl groups, R3 and R?3 each, independently of the other, are hydrogen atoms or alkyl groups, R4 and R?4 each, independently of the other, 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.
