Process, dispersion and ink

摘要

A dispersion of an encapsulated particulate solid is described, which is obtained by a process comprising the steps of providing a dispersion comprising a particulate solid, a liquid medium and a dispersant which is obtained or obtainable by copolymerising a monomer composition; and cross-linking the dispersant in the presence of the particulate solid and the liquid medium, thereby encapsulating each particulate solid particle within a cross-linked dispersant shell.
