INK AND DEVELOPER COMPOSITIONS CONTAINING SUCH PAINTS. The present invention relates to an ink composition with a novel surface additive package for developing images. The additive package including a sol-gel silica, a PDMS silica, an organic spacer such as PMMA silicas and two HMDS silicas. Ink composition exhibits improved voltage control, higher print density, less ink remaining in the drum, lower ink consumption, and reduced drum contamination. The ink composition also exhibits improved rheological dry properties and improved fixed properties. These enhanced properties make this ink composition useful for high-speed printing while using less ink. |
