ABSTRACT:
New ester-containing quaternary pyridinium salts are provided having advantageous utility as charge control agents in electrostatographic toners and developers. The salts have the structure: ##STR1## wherein R.sub.1 is alkyl or aryl, X is --CH.sub.2 --.sub.n, Y is hydrogen, alkyl, alkoxy or halogen, Z.sup..crclbar. is an anion and n is an integer from 2 to 6.
Such ester-containing quaternary pyridinium salts also cause toner particles containing them to display lower fusing temperature and improved paper adhesion indexes.
