Curable inks comprising diurethane gelators

摘要

The disclosure provides curable inks including a diurethane gelator having the structure of Formula I.;
wherein R and R′ each, independently of the other, is a C1-C22 saturated aliphatic hydrocarbon group selected from the group consisting of (1) linear aliphatic groups, (2) branched aliphatic groups, (3) cyclic aliphatic groups, (4) aliphatic groups containing both cyclic and acyclic portions, any carbon atom of the saturated aliphatic hydrocarbon group may be optionally substituted with an alkyl group (cyclic or acyclic), wherein (1) and (2) groups have a carbon number of from about 1 to about 22 carbons, and wherein (3) and (4) groups have a carbon number of from about 4 to about 10 carbons; and X is selected from the group consisting of: (i) an alkylene group, (ii) an arylene group, (iii) an arylalkylene group, and (iv) an alkylarylene group.
