Abstract (en)
[origin: WO9302397A1] New electrostatographic toners and developers are provided containing novel charge control agents comprising ester-containing quaternary pyridinium salts having structure (I), wherein R1 is alkyl or aryl, X is (a), Y is hydrogen, alkyl, alkoxy or halogen, Z<-> is an anion and n is an integer from 1 to 6. Such ester-containing quaternary pyridinium salts also cause toner particles containing them to display lower fusing temperatures and improved paper adhesion indexes.
