Abstract

Abstract An ink composition is provided having the properties of stability and uniformity of performance under ink jet printing conditions and desired printing properties can be obtained with hot melt ink compositions consisted of a resinous binder comprised of the compound of the formula wherein R₁ represents a polymerized fatty acid residue with two carboxylic acid groups removed R₂ and R₃ are the same or different and each represent an alkylene with up to 12 carbon atoms, a cycloalkylene with 6 to 12 carbon atoms, an arylene with 6 to 12 carbon atoms or an alkarylene with 7 to 12 carbon atoms and R₄ and R₅ are the same or different and each represents an alkyl having up to 36 carbon atoms, a cycloalkyl having up to 36 carbon atoms and aryl having up to 36 carbon atoms or an alkaryl having up to 36 carbon atoms said resinous binder having a melt viscosity of less than 250 CPS at 50 degrees C and a colorant distributed through the resinous binder in an effective amount sufficient to impart a predetermined color to the resulting hot melt ink composition.
