Abstract

The invention relates to an antimicrobial layer material comprising a layer with a particulate biocidal active ingredient and, on top of that, a layer as transport control layer, wherein the transport control layer is depositable or has been deposited in an afterglow PE-CVD method. The invention further relates to a substrate coated with such an antimicrobial layer material, to the use of a plasma-polymeric layer deposited in an afterglow PE-CVD method as transport control layer for a particulate biocidal active ingredient, and to a method of producing an antimicrobial layer material and to a method of producing a substrate comprising an antimicrobial layer material.
