Appeal No. 1996-1045
Application No. 08/143,415
3. A pigmented, stereoregular, branched-mono-1-olefin polymer composition
comprising:
(a) tris(3,5-di-tert-butyl-4-hydroxybenzyl)isocyanurate;
(b) bis(2,4-di-tert-butylphenyl)pentaerythritol diphosphite;
(c) a costabilizer selected from the group consisting of sodium stearoyl
lactylate, calcium stearoyl lactylate, calcium lactate, and mixtures thereof;
(d) 2-Naphthalenecarboxyamide, N,N’-(2-chloro-1,4 phenylene)bis[4-
[2,5-dichlorophenyl)azo]-3-hydroxy-;
(e) a stereoregular, branched-mono-1-olefin polymer.
The examiner relies on the following reference in rejecting the appealed claims:
Yukawa 4,366,280 Dec. 28, 1982
Claims 3 through 10 stand rejected under 35 U.S.C. § 103 as being unpatentable over
Yukawa. We reverse this rejection.
In reaching our decision in this appeal, we have given careful consideration to the appellant’s
specification and claims, to the applied prior art reference and to the respective positions articulated by
the appellant and the examiner. We make reference to the examiner’s answer (Paper No. 10, mailed
August 17, 1995) for the examiner’s reasoning in support of the rejection, and to the appellant’s
amended brief (Paper No. 11, filed September 5, 1995) for the appellant’s arguments thereagainst.
Appellant’s invention is directed to a pigmented, stereoregular, branched-mono-1-olefin
polymer composition comprising (e) a stereoregular, branched-mono-1-olefin polymer, a specific
pigment, i.e., (d) 2-Naphthalenecarboxyamide, N,N’-(2-chloro-1,4 phenylene)bis[4-[2,5-
