New amide-containing quaternary ammonium salts are provided having advantageous utility as charge control agents in electrostatographic toners and developers. The salts have structure (I), wherein R1 is C1-C6 alkyl or aryl, R2 and R3, which can be the same or different, are alkyl or aryl, R4 is alkyl, aryl or aralkyl, R5 is hydrogen or alkyl, X is (a), Z<-> is an anion and n is an integer from 2 to 6. Such amide-containing quaternary ammonium salts also cause toner particles containing them to display lower fusing temperatures and improved paper adhesion indexes. |
