Appeal No. 1997-4104
Application 08/383,238
wt.%, based on the total weight of said binder component, of a
polyvinylidene fluoride polymer having a melt viscosity of at
least 40 kPoise, and from 0 wt.% to about 65 wt.%, based on
the total weight of the binder component, of a polymer
compatible with polyvinylidene fluoride;
(b) from about 30 wt.% to about 70 wt.%, based on the
weight of said paint composition, of a solvent component; and
(c) a pigment, wherein said pigment is present in said
composition at a pigment-to-binder weight ratio of from 0 to
about 0.8.
12. A coated substrate, said substrate including at
least one surface, wherein at least one surface of said
substrate is coated with a paint including at least 35 wt.% of
a polyvinylidene fluoride polymer having a melt viscosity of
at least 40 kPoise.
The sole reference now relied upon by the examiner is:
Bacque et al. (Bacque) 5,095,081 Mar. 10,
1992
The appealed claims stand rejected 35 U.S.C. § 103 as
unpatentable over Bacque.
We do not sustain the stated rejection.
The subject matter on appeal is directed to a paint
composition comprising, inter alia, a binder component of a
polyvinylidene fluoride (PVDF) polymer having a melt viscosity
of at least 40 kPoise. Appellants’ composition finds
particular utility as an exterior use low gloss paint. Low
