The present invention provides novel anionic modified rosin ester resins having a high BRC content, up to 100% BRC. The resins of the present invention are useful as emulsion, dispersion, or solution resins. High BRC content pigment grind vehicles, coatings, and finished inks can be prepared using the resins of the present invention. Advantageously, the finished inks of the present invention have equal to or superior properties compared to current commercially available inks sold as sustainable products, but having little to no BRC content. The present invention represents a significant step towards developing sustainable inks and coatings that are better for the environment.

This disclosure is directed to formulations for inks and methods for achieving those formulations for use in an emerging class of variable data digital lithographic image forming devices. Specific sub-system requirements that are unique to the emerging architecture caused an exploration of formula boundaries that, through experimentation, were determined to substantially reduce particle sizes for the color pigments enabling a higher latitude for ink image thickness. Experimentally-derived behavior in reducing particle size and adjusting rheological properties results when a inks are processed using a 3-roll mill with cooling employed. Inks demonstrated a preferably reduced preferred particle size distribution enabling a higher latitude for ink image thickness down to about 0.5 microns. Improved rheological profiles allow the inks to have higher zero-shear or static viscosity to be less runny and to allow more consistent flow into and through ink loaders and Anilox systems to a reimageable surface of an imaging member.
