Modified Dye for Water-Fast Ink-Jet Printing
Modified Dye for Water-Fast Ink-Jet Printing
摘要
Abstract
A quaternary ammonium compound containing amino acid residue was synthesized by Converting 3-chloro-2-hydroxy- propyalkyldimethylammonium chlorides into its epoxide derivatives, then attaching an amino acid to the epoxide derivatives synthesized a quaternary ammonium compound containing amino acid residue. Modified dyes were prepared by the ionotropy of anionic dyes with the quaternary ammonium compound containing amino acid residue. It was discovered that the modified dyes exhibited an excellent pH controllable solubility. These modified dyes have good water solubility at pH> 8.0, but they were water insoluble at pH < 6.5. On the printing paper, modified dyes in water-based ink-jet print ink could convert to water insoluble form and give prints excellent water fastness.关键词
