ABSTRACT:
An article is described comprisinga substrateand a plasma polymer coating comprising silicon, oxygen and carbon bonded to the surface of the substrate, in respect of which coating the following applies in the case of determination by means of ESCA:the mole ratio O: Si is >1.25 and <2.6and the mole ratio C: Si is >0.6 and <2.2,according to a preferred embodiment the coating containsat least 22 and at most 27 atomic percent Si,at least 25 and at most 50 atomic percent O andat least 25 and at most 50 atomic percent Cbased on its total atomic number without hydrogen and/or fluorine.
