(Answer, page 8) that it would have been obvious to use the
microwave drying of Ayers "because the microwave drying of
Ayers, et al. drys the ink as desired by Miyamoto, et al."
She further asserts (Answer, page 11) that
Ayers does not limit drying to any particular
recording sheet. And Miyamoto does not prohibit
drying, in fact Miyamoto, et al. teach to dry the
ink receptive layer in example 1. Therefore,
Miyamoto, et al. desire a dried recording medium.
Appellants have not given sufficient reason why
Miyamoto would not want a dried recording medium in
the ink jet art.
First, the drying of Example 1 of Miyamoto referenced by
the examiner (Answer, page 11), occurs during the preparation
of the medium for use in a printing process, not during the
printing process itself. Furthermore, Miyamoto discloses in
column 2, lines 54-62, that
for the purpose of producing an ink jet recording
sheet having a high rate of ink absorption so as to
render the ink apparently dry immediately after the
application, it is most effective to construct the
uppermost layer, with which the ink droplets come in
first contact, with pigment particles of a suitable
size to utilize the capillary effect of the
interparticle voids or to provide a porous layer of
the similar pore size or pore radius to absorb the
ink. (emphasis added)
In other words, Miyamoto discloses that the recording medium
dries immediately by itself by virtue of the porosity of the
