PROBLEM TO BE SOLVED: To obtain a reactive surfactant making a coating film or a film formed from its aqueous dispersion or emulsion having an excellent water resistance and a sufficient strength. SOLUTION: This surfactant is composed of a hydrophilic portion having at least one group selected from among isocyanate, block isocyanate and epoxy groups and a hydrophobic portion having a 6-100C hydrocarbon group containing an aromatic ring(s), and contains oxyethylene groups in a content of 20-97 wt.%. The surfactant is used as a dispersing agent. COPYRIGHT: (C)2005,JPO&NCIPI
