Abstract
Paper coating pigments comprising a product obtained by the controlled mechanical delamination of kaolin particles. The pigments provide improved opacification, brightness, printing properties and gloss compared to conventional delaminated kaolin pigments. The pigment of the invention is particularly useful for coating light weight printed paper and provides a unique combination of high opacity, brightness and gloss not available when using other kaolin pigments. The novel pigment is specifically designed to replace plastic pigments and (or) titanium dioxide in coating formulations while maintaining or improving desired paper properties.
