ABSTRACT:
A smearfast, waterfast, and fast drying ink is provided, employing macromolecular chromophores (MMCs) and both ionic surfactants and zwitterionic, or amphoteric, surfactants, in which the ionic surfactant is of the opposite polarity of the MMC. Macromolecular chromophores are pigments whose surface has been treated to provide either anionic or cationic functional groups thereon. The zwitterionic surfactant gives rise to waterfastness, while the ionic surfactant gives rise to both smearfastness and fast drying.
