摘要:
Non-aqueous pigment dispersions exhibit improved dispersion quality and/or stability for a specific selection of quinacridone pigments, diketopyrrolo-pyrrole pigments and azo pigments by using specific naphthol AS dispersion synergists. The non-aqueous pigment dispersions can be advantageously used in inkjet inks inkjet printing methods.
