Beschreibung
Zusammenfassung:	A polymeric product with at least one surface subject to wear or abrasion, at least a portion of which product includes microcapsules of an indicator substance which is released to indicate a state of wear has been reached. The microencapsulated indicator substance may be a fragrance or a colorant. The indicating portion or zone may be a layer or a thin sheet of microcapsules in rubber or in the polymeric material making up the body of the product. There may be more than one indicating layer or zone in the product. The various zones may contain different fragrances or colorants, which may provide progressive indication of the state of wear. L'invention concerne un produit polymérique présentant au moins une surface soumise à une usure ou à une abrasion, au moins une partie dudit produit comprenant des microcapsules d'une substance indicatrice qui est libérée pour indiquer qu'un état d'usure a été atteint. La substance indicatrice micro-encapsulée peut être un parfum ou un colorant. La partie ou la zone d'indication peut être une couche ou une feuille mince de microcapsules dans du caoutchouc ou dans le matériau polymérique constituant le corps du produit. Il peut exister plus d'une couche ou zone d'indication dans le produit. Les diverses zones peuvent contenir des parfums ou colorants différents, ce qui peut donner une indication progressive de l'état d'usure.
