Abstract
Disclosed is an aqueous ink composition comprising an aqueous liquid vehicle, a colorant, and an additive wherein, when the ink has been applied to a recording substrate in an image pattern and a substantial amount of the aqueous liquid vehicle has either evaporated from the ink image, hydrogen bonds of sufficient strength exist between the additive molecules so that the additive forms hydrogen-bonded oligomers or polymers.
