ABSTRACT:
New electrostatographic toners and developers are provided containing charge-control agents comprising quaternary phosphonium trihalozincate salts having the structure: ##STR1## wherein R is selected from an unsubstituted alkyl group having from 1 to 24 carbon atoms; a substituted alkyl group having from 1 to 24 carbon atoms substituted with one or more hydroxy-, carboxy-, alkoxy-, carboalkoxy-, acyloxy-, nitro-, cyano-, keto- or halo-groups; a cycloalkyl group having from 3 to 7 carbon atoms; an alkaryl group having from 1 to 20 carbon atoms in the alkyl group and 6 to 14 carbon atoms in the aryl group; an aralkyl group having from 1 to 4 carbon atoms in the alkyl group and 6 to 14 carbon atoms in the aryl group wherein the aryl group is unsubstituted or substituted with one or more alkyl-, hydroxy-, carboxy-, alkoxy-, carboalkoxy-, acyloxy-, amino-, nitro-, cyano-, keto- or halo-groups; phenyl or substituted phenyl;
R.sup.1, R.sup.2 and R.sup.3, which can be the same or different, are independently selected from hydrogen; an alkyl group having from 1 to 24 carbon atoms; hydroxy-; carboxy-; alkoxy-; carboalkoxy-; acyloxy-; amino-; nitro-; cyano-; keto-; or halo-groups; and
X, which can be the same or different, is independently selected from fluorine, chlorine, bromine or iodine.
