Abstract
The present invention provides solvent-based high opacity inks and coatings. The high opacity inks and coatings comprise one or more binders, TiO2 pigment, polymeric void hollowsphere particles, and one or more organic solvents. The inks and coatings may also include mica-based pigments and aluminum pigments. The high opacity inks and coatings of the invention are suitable for use on packaging wherein a high opacity ink or coating is needed to, for example, hide undesired visual effects, or to protect the packaged goods.
