Coating in particular for toner drums, and method for producing the same

摘要

The present invention relates to an electrically conductive coating that is producible by hydrolytic condensation of a mixture comprising at least one silicon compound of the general formula SiXnR(4-n) (I), wherein at least one of the groups R is a mercapto-substituted alkyl or aryl group; and a compound of the general formula ZaSiYbR(a-4-b) (II), wherein the group Z is a quaternary ammonium salt, for example. Said coating is particularly suitable for toner transfer drums, and exhibits high scratch resistance and good adhesion to the substrate.
