A kaolin clay pigment comprises a coarse kaolin clay or a blend of a coarse kaolin clay with a fine kaolin clay. The kaolin clay is defined into a coarse fraction and a fine fraction. The fine fraction is discarded and the coarse fraction generally will have 'blocky' particles at its coarse end and 'platy' particles at its fine end with an overall shape factor greater than 12.
