摘要： A composition comprising pulverized hydrous kaolins having a particle size distribution meeting the following ratio: ( cumulative   mass   at   0.5   μm ) ( cumulative   mass   at   2   μm ) ≤ 0.5 , and a median particle size (D50) less than or equal to 2.0 μm and a composition comprising hydrous kaolins having the particle size distribution, the median particle size (D50), and certain Hegman dispersion according to the “SSM” V-T Alkyd Hegman Test are disclosed. Also disclosed is a method of preparing a composition comprising inventive hydrous kaolins, as well as a method of increasing the dispersion rate of hydrous kaolins. Products, such as inks, paints, polymer products, rubber products, and coatings, using the inventive hydrous kaolins are also disclosed.
