<p>A product and a process for the preparation of a precipitated calcium carbonate (PCC) and an ink jet recording paper, incorporating the precipitated calcium carbonate is disclosed. The precipitated calcium carbonate is dewatered and comminuted in the presence of an amphoteric and/or anionic dispersant to produce a high solids PCC composition. When used in coating formulations the PCC has a surface morphology and chemistry that enhances the printability of ink jet paper. Ink jet recording paper incorporating the PCC of the present teachings has reduced ink feathering and spreading as well as improved optical density, dry time, and water fastness. ® KIPO & WIPO 2007</p> |
