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 $0.1{\sim}1.0\;wt%$.

탄소수가 $8{\sim}16$ 범위인 장쇄 알킬비닐에테르와 무수 말레인산의 공중합반응으로 올리고머형 음이온성 계면활성제(RmF-Na)를 합성하고, 이의 형광성 음이온성 계면활성제(RmF-Na)를 공중합물인 maleic anhydride vinyl ether와 3-aminophenol를 알카리 매질하에 축합반응으로 락톤고리를 개열하면서 얻어졌다. 소수성 안료인 ${\alpha}-copper\;phthalocyanine$, copper phthalocyanine green 및 carbon black 등에 대한 분산성을 비교 검토한 결과 탄소수가 $8{\sim}10$범위의 장쇄 알킬기를 갖는 형광성 구조를 갖는 올리고머형 음이온성 계면활성제가 $0.1{\sim}1.0\;wt%$ 농도 범위에서 phthalocyanine과 carbon black의 분산성을 가져왔다.
