Fluorescent anionic oligo surfactants were synthesized by the condensing products of long chain alkylvinylether-maleic anhydride cooligomers and resorcinol including dye structures. Their various surface activities and dispersing action were studied on the aqueous solution. These oligo surfactants exhibited a remarkable surface tension lowering property, lower foaming and a large dispersing action for the particles of α-copper phthalocyanine blue. Further it was ascertained that the binding of oligo surfactant onto the pigment surface caused the deviation towards lower wavelengths at the maximum fluorescent intensity as compared with aqueous oligo surfactant solutions, These surface active properties of the oligo surfactants may be attributed to rigid and hydrophobic structure of dye groups, besides surface-active groups of alkylether groups and carboxylic group of the anionic oligo surfactants.
