Synthesis of new yellow synergists based on pigment yellow 150 for inkjet applications

ABSTRACT

Inkjet technology using pigment requires pigment dispersity as well as the stability in solvents. New synergist PY-150ASA2 was synthesized by substituting 1,4-butane sultone in order to give the dispersity and the stability. The original pigments showed very low solubility in water and organic solvents. PY-150ASA2 has better solubility and stability in water compared to the pigment. Through the storage stability test, PY-150ASA2 disperses well in the pigment and has a smaller particle size than that of the solsperse 22000, a commercialized synergist. Synergest is expected to be applied to pigment inks for the improved performance.
