Abstract
A pneumatic vehicle tire which includes a sealant layer at least on the inner surface opposite the tread. The sealant layer has a radially inward-facing surface running in the axial direction substantially parallel to the belt package. Also provided is a process for detecting a pneumatic vehicle tire with a sealant layer and to a process for recycling a pneumatic vehicle tire with sealant. The sealant layer has at least one luminescent agent on its radially inward-facing surface. The tire is detected via the luminescent agent.
Claims15
A pneumatic vehicle tire comprising:
- a tread,
- sidewalls, and
- a sealant layer disposed on an inner layer opposite the tread,
- wherein the sealant layer has a radially inward facing surface running in the tire axial direction, and has a plurality of individual spaced apart layers with luminescent agent disposed atop the radially inward facing surface of the sealant layer,
- wherein (i) the plurality of individual spaced apart layers with luminescent agent are arranged as a plurality of spaced apart strips running parallel to one another, or (ii) the plurality of individual spaced apart layers with luminescent agent are arranged as discrete regions randomly distributed atop the radially inwardly facing surface of the sealant layer, and
- wherein, when illuminated with light, the plurality of individual spaced apart layers with luminescent agent provide visually contrasting effect with the radially inward facing surface of the sealant layer to enhance detection for recycling the tire.
