A zinc benzoate compound represented by the following general formula: ##STR1## wherein R.sub.1 represents an alkyl or aralkyl group; and R.sub.2 and R.sub.3, independently from each other, each represent an alkyl, aralkyl, aryl, alkoxy or acyl group, an amino group which may be substituted, a nitro group or a halogen atom. The compound of the general formula (1) is colorless, highly stable and has excellent dispersibility in a binder resin for an electrophotographic toner, and can impart excellent frictional electrification properties to a toner, therefore being useful particularly as a charge control agent for an electrophotographic toner.
下面是通用式为##STR1##的苯甲酸锌化合物,其中R.sub.1代表烷基或芳基烷基;R.sub.2和R.sub.3独立地表示烷基、芳基烷基、芳基、烷氧基或酰基、可能被取代的氨基、硝基或卤素原子。通式(1)的化合物是无色的,高度稳定的,并且在电子照相色调剂的粘合剂树脂中具有优异的分散性,并且可以赋予色调剂优异的摩擦电化性能,因此特别适用于电子照相色调剂的电荷控制剂。
