▎ 摘  要

NOVELTY - The vehicle tire has a sealant layer (5) whose inner surface is opposite to a tread (1). A non-black layer is arranged radially inward on the sealant layer. The non-black layer is white or colored and is provided with colorant. The colorant is selected from inorganic and organic colorants. The non-black layer is provided with colorant having metal atom or metal ion. The non-black layer is formed from a dispersion, and the dispersion or the solution containing from 1 to 80% by weight of colorants. The non-black layer is formed from a film. The sealant contains filler which is given a black hue, such as carbon black or graphite or graphene or carbon nanotubes. USE - Pneumatic vehicle tire. ADVANTAGE - The colorants are used in material-saving manner. The colorants are stable and retain their color over longer period of time. The suspension is applied easily in material-saving manner. The flow behavior and the sealing effect of the sealant are ensured. The cohesion of sealant is increased and the tackiness of sealant is reduced. The local strength and tear properties of sealant are improved. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) a method for detecting pneumatic vehicle tire; and (2) a method for recycling pneumatic vehicle tires. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the pneumatic vehicle tire. Tread (1) Belt package (2) Sealant layer (5) Non-black location (6) Side wall (7)
