Abstract
The invention relates to an article, in particular a glove, a condom, or the like, which is comprised of a flexible rubber and/or plastic, is embodied having at least one section of the surface intended contact or rest against human skin, which article is provided with a slip coating in a section of the surface. This slip coating is comprised of a polymeric material and at least in sections, has repeating shape deviations of the surface that are recessed in relation to a raised, net-like structure. The ratio of the average spacings between the shape deviations to their depth in relation to the raised, net-like structure is between 500:1 and 5:1 and the average roughness depth is between 0.5 and 100 .mu.m, preferably between 1 and 40 .mu.m.
