Abstract
Anhydride and its fluorescent anionic surfactants(RmF-Na) were obtained from alkali neutralization which opens the lactone ring of the condensing materials produced by maleic anhydride alkylvinylether copolymer and 3-aminophenol. Their dispersion abilities were studied on hydrophobic pigments such as ${\alpha}-copper$ phthalocyanine, copper phthalocyanine green, and carbon black. Moderate oligomer type anionic surfactants(RmM-Na) were synthesized from $C_8{\sim}C_{16}$ long chain alkylvinylether and maleic a lengths $C_8{\sim}C_{10}$ of long chain alkyl group in the structure of oligomer type anionic surfactant having fluorescent structure played an important role in the dispersion stability of the phthalocyanine and carbon black pigments within the concentration range of about $0.1{\sim}1.0\;wt%$.
Keywords
