| abstract |
The present invention relates to surfactants that help improve image quality attributes, in particular chroma (i.e., color saturation), and ink-jet inks formulated with the same to produce inks exhibiting more than one of the desirable properties such as improved chroma, bleed control, edge acuity, and surface retention, thereby improving image quality. More specifically, the invention relates to surfactants that form relatively large aggregated structures (micelles) of geometry other than spherical, hence fourth referred to as lamellae forming surfactants. |
