Appeal No. 1998-2188
Application No. 08/581,424
OPINION
The obviousness rejection of claims 2 and 4 through 10 is
reversed.
Takasu (Abstract) and the admitted prior art
(specification, page 3) disclose the same resin having
polysiloxane-structured oligomer and a perfluoroalkyl group-
containing oligomer that is used as a protective layer on a
phosphor/fluorescent layer in a radiation image storage panel
and a radiation image conversion panel, respectively.
Kano uses at least two protective layers 13a and 13b to
prevent moisture from reaching an underlying layer of phosphor
12 (column 3, lines 10 through 20). According to Kano, “a
composite protective layer having the layer structure as shown
in FIG. 1 may preferably have a very small water vapor
transmission rate in the direction of from 13b to 13a and a
relatively large water vapor transmission rate in the
direction of from 13a to 13b by selecting suitable materials
for the protective layers” (column 3, lines 41 through 47).
In framing the obviousness rejection, the examiner stated
(Answer, page 4) that:
