Abstract
Abstract Paint compositions suitable for forming decals which can be applied to vehicle tire sidewalls. The compositions comprise a saturated elastomer having a glass transition temperature not higher than -40 degrees C., a pigment which is preferably titanium dioxide in an amount in the range of 0.5 to 10 times the weight of elastomer, and a solvent. Compositions of this invention are resistant to ultraviolet light and ozone, maintain color and integrity during outdoor aging, and have a long fatigue life.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
109 words
A transfer decal having high resistance to ultraviolet light and ozone and having adherence to tire sidewalls, said decal comprising: (a) a saturated elastomer having a glass transition temperature not higher than about -40 degrees C.; (b) a pigment, the amount of said pigment being in the range of about 0.5 to about 10 times the weight of said elastomer, said decal being essentially devoid of unsaturation and free of staining and antiozonants, and forming a film having a flexural durability of at least about 100,000 cycles at room temperature and at least about 80,000 cycles at -40° C. when flexed at 5 Hz and a 15 percent strain.
