epoxide group containing materials of (a); and
(c) a curing agent adapted to cure the one or more epoxide
group containing materials of (a). (Column 1, lines 29-45.)
Further, Schappert teaches that the curable composition “can
contain a variety of additives including pigments,
reinforcements, thixotropes, plasticizers, extenders,
stabilizers and antioxidants.” (Column 5, lines 63-66.)
The examiner admits that Schappert does not teach component
(c), i.e. the ground vulcanized rubber particles, as recited in
appealed claim 1. (Answer, page 3.) In an attempt to account
for this difference, the examiner relies on the teachings of
Magnani and Sugimori.
Magnani teaches a sound absorbing coating, which is
particularly suitable for coating the structural parts of motor
vehicle bodies, containing a resin such as an epoxide resin, an
organic carrier, and a filler in the form of particles of
natural gum or synthetic rubber having a particle size between
100 and 1,500 microns (e.g., pulverized used tires). (Page 2,
right column.)
Sugimori discloses a curable epoxy resin composition
comprising an epoxy resin and vulcanized rubber particles having
a particle size of 0.5 to 30 microns, which are obtained by
