Abstract (en)
[origin: DE4237661A1] The invention concerns electrostatic toners containing a polymeric binder and, as charge stabilizer, a compound of formula (I) in which n is 2 to 6; Q is a 2- to 6-valent group derived from benzene, cyclohexane, naphthalene, triphenylene or perylene; X is a chemical bond, oxygen, sulphur, sulphonyl, carbonyl or a group of the formula O-CO, CO-O, NH-CO or CO-NH; L is a bridging member; R<1>, R<2> and R<3> are C1-C4 alkyl or C5-C7 cycloalkyl, or R<1> and R<2> together are 1,4-butylene, 1,5-pentylene or 1,5-(3-oxapentylene), or the group (a) is the pyridinium or 3-carboxylpyridinium ion; and An<-O> is the anion equivalent. The invention also concerns the use of such compounds as charge stabilizers in electrostatic toners.
