Abstract
Described herein are opaque water-based inks that include water and an opacity-providing polymer component. In one aspect, the opacity providing polymer component is a hollow sphere polymer material. The opacity-providing polymer material may replace all or part of white opacifying pigment material, such as titanium dioxide. Also described herein is a method of opacifying a printing ink by adding hollow sphere resin particles and a colorant to a printing ink that comprises water as a volatile component.
