Appeal No. 2002-0466 2
Application No. 09/456,273
THE INVENTION
The invention is directed to a sidewall of a tire or a veneer thereof. The sidewall
comprises at least one elastomer and a carbon black having specific DBP, Tint values and
CTAB values. Additional limitations are described in the following illustrative claims.
THE CLAIMS
Claims1, 33 and 47 are illustrative of appellants’ invention and are reproduced
below:
1. An article having a non-abrading surface, wherein at least said surface
comprises at least one elastomer and a carbon black having a DBP value of at least
about 50 cc/100g, a Tint value of at least about 100% ITRB, and a CTAB value of
at least about 80m2/g, wherein said non-abrading surface is a sidewall of a tire or a
veneer thereof.
33. An article of manufacture prepared from a composition comprising at
least one elastomer and a carbon black having a DBP value of at least about 50
cc/100g, a Tint value of at least about 100% ITRB, and a CTAB value of at least
about 80m2/g, wherein said article of manufacture is a sidewall of a tire or a veneer
thereof.
47. A process for making a rubber article having a non-abrading surface,
said process comprising the step of forming at least a portion of said non-abrading
surface of said rubber article from a composition comprising an elastomer and a
furnace carbon black having a DBP value of at least about 50 cc/100g, a Tint value
of at least about 100% ITRB, and a CTAB value of at least about 80m2/g, whereby
said article exhibits higher gloss and/or a lower jetness value relative to an article
formed from a composition using N650 carbon black at the same loading level,
wherein said non-abrading surface is a sidewall of a tire or a veneer thereof.
