Abstract
Styrene-acrylic dispersants for use in pigment dispersions have lower viscosities than benchmark formulations such as nitrocellulose, dimer-acid based polyamides, and thermoplastic polyurethanes, prepared under otherwise identical conditions. Lower viscosities allow for the preparation of similarly viscous dispersions and inks with the styrene-acrylics when compared to traditional dispersants, at either (a) lower solvent levels, or if solvent levels are to be maintained, (b) higher pigment and solids loadings.
