Abstract

Disclosed is the use of low molecular weight polymeric acid derivatives and components for ink jet phase change inks. A preferred blend of poly(ethy1ene-co-acrylic acid) having acrylic acid of 20 percent (5 parts by weight), with viscosity modifiers such as 12- hydroxydodecanoic acid (55 parts by weight), azelaic acid (35 parts by weight), and Neoprene Blue 807 dye (5 parts by weight) yields an ink with a hardness value of 80. A draw down of this ink produces images with 1.2 optical density. Other binders include monocarboxylic acid, poly(viny1acetate-co-crotonic acid) that yields a hardness value of 90.5. The acid functionally enables a higher degree of dye loading.
