Reaction Conditions

Reaction Steps

In a stainless steel beaker were combined about 3170 grams of stearyl stearamide (KEMA IDE S-180, Witco), about 1553 grams of a rosin ester tackifier resin available commercially as Arakawa KE-100 (glycerol ester of hydrogenated abietic (rosin) acid available from Arakawa Chemical Industries, Ltd. of Osaka Japan) and about 299 grams of Ink Yellow 869 (Milliken Chemical Company). In addition, about 10.0 grams of Uniroyal Naugard 445 anti-oxidant were added. The materials were melted together in a temperature controlled oven at about 140° C. The molten mixture was stirred and further heated in a controlled temperature heating mantle at about 110° C. To this stirred mixture was added about 1266 grams of UNIREZ 2970 (a dimer acid-based tetraamide material manufactured by Union Camp and formed by the reaction of one mole of dimer acid, two moles of ethylene diamine, and two moles of stearic acid) in several portions at a rate so as to avoid freezing the mixture. Offer stirring for about ½ hour, the yellow ink was filtered through a heated Mott apparatus (available from Mott Metallurgical) using #3 Whatman filter paper and a pressure of about 15 psi. The filtered phase change ink was poured into molds and allowed to solidify to form ink sticks.
