    摘要: A pigment dispersant is disclosed comprising a tri-block copolymer having a first block comprising a glycidyl(meth)acrylate reacted with a napthoic acid, a second block comprising (meth)acrylic acid alkyl esters, and a third block comprising (meth)acrylic acid alkyl esters, wherein said third block is different from said second block. The dispersant is suited for use in a nanoparticulate dispersion comprising pigment particles having an average primary particle size of less than 100 nm.
