The present invention relates to an electrically conductive coating which is producible by hydrolytic condensation of a mixture including at least one hydrolysable silicon compound of general formula SiXR(I), wherein at least one of the R radicals is a mercapto-substituted alkyl or aryl group and is a compound of general formula ZSiYR(II), wherein the Z radical is for example a quaternary ammonium salt, whereby the mixture to be hydrolytically condensed comprises at least one portion of an ether containing and alkyl group. The coating is particularly suitable for toner transfer drums and has high scratch resistance and good adhesion to the substrate.

Antistatic coating, in particular for toner transfer drums

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 SiX R (I), wherein at least one of the groups R is a mercapto-substituted alkyl or aryl group; and a compound of the general formula Z SiY R (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.
