Abstract

Mechanical dry milling of organic pigments in the presence of mono-dispersed silica nanoparticles gave core–shell hybrid pigments with uniform size and shape reflecting those of the inorganic particles, in striking contrast to conventional milling as a breakdown process, which results in limited size reduction and wide size distribution.
