ABSTRACT:
The present invention is drawn to ink compositions and methods for ink-jet recording. The ink compositions can include a non-aqueous HAPS-free solvent system; a binder system, including at least one of i) an acrylic resin, or ii) a first vinyl chloride-vinyl acetate resin, which is at least substantially soluble in the solvent system; and a pigment milled in the presence of a second vinyl chloride-vinyl acetate resin. Further, at least one solvent of the solvent system can serve as a dispersing and diluent solvent for the pigment.
