insoluble to methylene chloride. In addition, the substrate must
have specific Tg and a specific linear thermal contraction
coefficient relationship with a charge transport layer. See
both claims 21 and 26.
The examiner has rejected claims 2, 3, 6 through 13, 21 and
25 under 35 U.S.C. � 103 as unpatentable over the combined
teachings of Yu’481 and Takano. The examiner’s rejection is
predicated on the contention that:
It would have been obvious to one having
ordinary skill in the are at the time the
invention was made to substitute the substrate
having an undercoat layer comprising nylon taught
be Takano et al. for the substrate of Yu because
Takano et al. states that providing the substrate
with an undercoat layer prevents any reduction of
electrostatic charging property and improves the
adhesive property.
In so contending, the examiner appears to take the position that
a substrate having an undercoat layer of Takano meets the claimed
substrate. We cannot subscribe to the examiner’s position.
Yu’481 describes an electrophotographic imaging member which
can be used in an electrostatographic process. See column 1,
lines 5-7. The electrophotographic imaging member comprises,
inter alia, a substrate and a charge transport layer applied by
solution coating in methylene chloride. See example 1 at columns
14 and 15. The difference in thermal contraction coefficient
