Abstract
A solubilizing agent and a compound made by reacting selected nucleophiles, including fatty acid reactants and amines with an isocyanate are disclosed. The addition of the isocyanate and the different nucleophiles will create a di-urethane tetra-amide solubilizing agent product. The polyamide-solubilizing agent is useful as an ingredient in a phase change solid imaging material and as carrier compositions used to make phase change ink jet inks.
