| titleOfInvention | Paper coating pigments |
| abstract | Paper and other substrates, especially machine paper coating compositions such as light weight coated (LWC) paper, comprise an aqueous suspension of particulate pigments together with a binder, the particulate pigment comprising the following components: (a) Araleite-type and rhombohedral particles mainly consisting of an aragonite-type or rhombohedral particle shape, or from about 40:60 to about 60:40 (e.g., about 50:50) aragonite-type: rhombohedral mass ratio A first component that is precipitated calcium carbonate of shape and a second component that is a processed granular hydrous kaolin clay having a shape factor of greater than about 25 and a steepness of greater than about 20; or (b) a predominantly regular spherical particle shape A first component that is finely divided calcium carbonate consisting of particles having a second component that is a processed granular hydrous kaolin clay having a shape factor of greater than about 45 and an average equivalent particle size (d 50 ) of less than about 0.5 μm; or (C) Mainly about 40:60 to about A first component that is precipitated calcium carbonate consisting of an aragonite-type and rhombohedral-shaped aragonite-type and rhombohedral-particle shape of 60:40 (eg, about 50:50) and a shape factor of less than about 25 A second component which is a processed granular hydrous kaolin clay. |
