Appeal No. 96-3946
Application No. 08/208,317
In the specification (page 4), appellant discloses that
the purpose of the invention is to provide an improved
recording sheet suitable for ink jet printing and which
"exhibit rapid drying times when imaged with aqueous inks."
Miyamoto states in column 2, lines 62-67, that the
intermediate layer with small particles provides high image
resolution and high ink absorptivity. In column 2, lines 44-
49, Miyamoto discloses that a larger and a higher rate of ink
absorption makes the ink dry faster. In other words, the
addition of Miyamoto's intermediate layer would seem to
enhance the properties of appellant's recording sheet, or
rather, not to materially and deleteriously affect the basic
and novel properties of the invention. Accordingly, we find
that claim 1 and claims 2 through 12, all of which depend from
claim 1, would have been obvious over Miyamoto.
Independent claim 13 is identical to claim 1 with a
further step of "thereafter exposing the substrate to
microwave radiation, thereby drying the recording liquid on
the recording sheet." The examiner relies on Ayers for
motivation to include a step of applying microwave radiation.
