ABSTRACT:
The invention provides new weakly acidic crosslinked vinyl polymer particles having utility as components of coating compositions, liquid electrographic developers, and layers of electrographic elements and records.
The polymeric particles of the invention are characterized in that each particle has a weakly acidic surface and an average diameter less than one micrometer and comprises a crosslinked vinyl addition copolymer obtainable by aqueous emulsion polymerization of a mixture of monomers in the presence of a polymerization initiator.
