Abstract:
An electrophotographic or electrographic liquid toner comprising:(a) a carrier liquid having a Kauri-butanol number less than 30;(b) a charge director; and(c) an organosol comprising(i) a (co)polymeric steric stabilizer having a weight-average molecular weight between 50,000 and 1,000,000 Daltons and a polydispersity less than 15, said steric stabilizer being covalently bonded to a thermoplastic (co)polymeric core that is insoluble in said carrier liquid,wherein the weight ratio of said (co)polymeric steric stabilizer to said thermoplastic (co)polymeric core is between 1/1 and 1/15, and said (co)polymeric steric stabilizer comprises a crystallizing polymeric moiety that independently and reversibly crystallizes at or above 22.degree.
