Abstract
An aqueous dispersion contains pigment colorant particles that are present in an amount of at least 5 weight % and up to and including 80 weight %; a dispersing polymer that is a hexyloxy benzoic acid polymer; 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. Such aqueous dispersions can be incorporated into aqueous inkjet ink compositions that can be used for forming opaque images such as white images using inkjet printing methods.
