| abstract |
The present invention relates to a rubber article, in particular a tyre, an air cushion or a drive belt, containing at least one basic, aminic, aromatic antiageing agent and having a non-black surface on the rubber article, for example in the form of letters and/or numbers and/or trademarks and/or pictures and/or - for example in tyres - a complete side wall. In order to counter, in an environmentally friendly manner, a colour change of the non-black surface as a consequence of migration of basic, aminic, aromatic antiageing agents from a rubber article into the non-black surface located thereon, it is proposed that the non-black surface contains inorganic acidic constituents. <IMAGE> |
