<p><P>PROBLEM TO BE SOLVED: To provide a dispersant for obtaining, by using a small amount of use, a dispersion excellent in dispersive properties, fluidity and storage stability, and further to provide a dispersant having dispersive properties and stability excellent in non-aggregation and fluidity which is suitable for offset inks, gravure inks, resist inks for color filters, inkjet inks, coating materials, coloring resin compositions and the like. <P>SOLUTION: The curable dispersant is obtained by reacting hydroxyl groups in a vinyl polymer having two hydroxyl groups on one terminal which is obtained by the radical polymerization of an ethylenically unsaturated monomer with acid anhydride groups in a tetracarboxylic acid anhydride in the presence of a compound having two hydroxyl groups and one thiol group in the molecule. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
