Abstract
Disclosed are kaolin compositions of at least one hydrous kaolin characterized by a particle size distribution where 98% of the particles are less than about 2.mu., 90% are less than about 0.5.mu. and the median particle size is less than about 0.3.mu.. Also disclosed is a process which involves the steps (i) preparing an aqueous slurry of at least one hydrous kaolin; (ii) separating the particles from said slurry so that the particle size distribution is such that 98% of the particles are less than about 2.mu., 90% are less than about 0.5.mu. and a median particle size is less than about 0.3.mu.; and (iii) drying said separated particles. Pigment pastes and electrodeposition paints containing said compositions as well as cationic electrodeposition of said paint on a substrate and the article of manufacture prepared thereby are disclosed.
