| 摘要 | An aqueous dispersion contains pigment colorant particles (of various types of materials) at 5 weight % and up to and including 80 weight %; a dispersing polymer that is prepared from the Diels Alder adduct of 3-maleimidopropionic acid and furfuryl (meth)acrylate; and an aqueous medium. The weight ratio of the pigment colorant particles to the dispersing polymer is from 19:1 to and including 2:1. This aqueous dispersion can be incorporated into an aqueous inkjet ink composition that can be used in various inkjet printing methods to provide opaque images particularly when titanium dioxide particles are used as the pigment colorant. | ||||||
