Abstract:
1. A solid phase change ink comprising: a semi-crystalline oligomer resin selected from the group consisting of a polyester, an oligoester, a polyesteramide and oligoesteramide; an optional colorant; and an ink vehicle, wherein the semi-crystalline oligomer resin is made from a condensation reaction of a dicarboxylic acid or anhydride or diester, a difunctional alkanol monomer, and an optional monofunctional end-capping reactant, and further wherein the oligomer resin is an oligoesteramide and has the following formula wherein R 1 , R 2 , and R 3 are independent from one another and further wherein R 1 is an alkylene group having from about 1 to about 20 carbons; alkyleneoxy having from about 1 to about 20 carbons; arylene group having from about 6 to about 20 carbons; or arylalkylene group having from about 7 to about 20 carbons; R 2 is an alkylene group having from about 1 to about 20 carbons; alkyleneoxy having from about 1 to about 20 carbons; arylene group having from about 6 to about 20 carbons; or arylalkylene group having from about 7 to about 20 carbons; R 3 is H; alkyl group having from about 1 to about 50 carbons; aryl group having from about 6 to about 50 carbon atoms or alkylaryl group having from about 7 to about 50 carbons; and n is a number of from about 1 to about 10.
