Pneumatic tire

Pneumatic tire description/claims

Pneumatic tires often desirably have indicial markings, such as trademarks or other markings. These indicia typically are formed directly into the rubber sidewall during the tire molding process. Thus, the indicia may be raised lettering or other shapes, and may be colored with white pigments or other colorants in the rubber compound.

It is sometimes desired to apply indicia directly to an already molded and cured tire, typically on the sidewall area. To do this, various coatings, inks and paints have been used to form indicia. However, poor adhesion or durability of the coatings usually leads to unacceptable performance of this type of indicia.

It would, therefore, be desirable to have a tire with indicia on a tire sidewall surface, wherein the indicia offers good durability.

The present invention relates to a pneumatic tire having a component comprising at least one elastomer containing olefinic unsaturation; and compound of formula I

wherein: R1, R3, R4, R5, R6, and R8 are each independently hydrogen, alkyl, aryl, halogen, or substituted or unsubstituted oxygen, nitrogen or sulfur atoms; R2 is hydrogen, alkyl, aryl, or is absent; R7 is substituted or unsubstituted oxygen, nitrogen, sulfur, or halogen; R9, R10, R11 and R12 are each independently hydrogen, alkyl, aryl, halogen, nitro or substituted or unsubstituted oxygen, nitrogen or sulfur atoms; and X is oxygen, sulfur, or nitrogen.
