Abstract (en)
[origin: EP0895131A2] Inter-polyelectrolyte complexes (I) are used as charge regulators and enhancers in electrophotographic toners and developers, in powders and powder lacquers suitable for triboelectric or electrokinetic spraying and in electret materials. Also claimed are electrophotographic toners, powders and powder lacquers containing (I), a styrene, styrene-acrylate, styrene-butadiene, acrylate, urethane or acrylic resin or a polyester and/or epoxide resin and 0.01-50, preferably 0.5-20 wt.% complex(es) (I).
