ABSTRACT:
A coated paper of improved optical and printing qualities, coated with a structured kaolinitic pigment. The pigment consists of porous aggregates of kaolin particles which are chemically bonded together. The pigment may be produced by chemically reacting a particulate kaolin with a metal chloride, such as silicon tetrachloride. The process for preparing the structured pigment is conducted under conditions such that the kaolinite structure is not impaired.
