Appeal 2007-1223
Application 10/007,149
The present invention relates to coating compositions having improved mar
and scratch resistance. The coating compositions generally comprise a film-
forming resin containing a plurality of dispersed organic or inorganic particles
having an average particle size ranging from 0.1 to 15 microns (Specification 2).
Representative claim 1, as presented in Appellants’ Brief, is reproduced below:
1. A powder coating composition comprising:
a film-forming resin; and
a plurality of particles having an average particle size between 1
and 15 microns dispersed in said resin, wherein the particles have a
hardness sufficient to impart greater mar and/or scratch resistance as
compared to no particle being present, and wherein the difference
between the refractive index of the resin and the refractive index of
the particles is less than one.
The Examiner relies on the following references in rejecting the appealed
claims:
Christie US 6,203,906 B1 Mar. 20, 2001
Harashima US 6,362,267 B1 Mar. 26, 2002
Claims 1, 6, 10-12, 15-17, 19-24, 26-40, 42-45, and 50-58 stand rejected
under 35 U.S.C. § 103(a) as unpatentable over Christie; and claims 41 and 59-63
stand rejected under 35 U.S.C. § 103(a) as unpatentable over the combination of
Christie and Harashima (Answer 3-4). We affirm the rejections.
