Appeal No. 1997-2070
Application 08/487,921
recording material differs primarily from the prior art
tonable, radiation sensitive recording material described and
exemplified by Bauer '802 in the requirement of a
polydiorganosiloxane component in the radiation sensitive
layer, which component functions to control the “adhesion
balance” of the tonable, radiation sensitive layer to the
support and the coversheet. In this regard, example 7 of
Bauer '802 includes a polyester, i.e., polycaprolactone having
a molecular weight of 15,000 which functions to provide an
adhesion balance between the radiation sensitive layer and
support in this prior art material. See Bauer ‘802 at column
13 and comparative example 1 in appellants' specification at
pages 11 and 12.
The crux of the examiner's stated obviousness rejection
of the appealed claims is set forth in the examiner's answer
at page 6 as follows:
[I]t would have been obvious to one of ordinary
skill in this art at the time of the claimed
invention to substitute the polydiorganosiloxane of
Hodakowski into the radiation-sensitive layer of
Bauer et al. [Bauer '802]. One of ordinary skill in
this art would have been motivated to make this
substitution because of the teaching of Hodakowski
that the polydiorganosiloxane adhesion balance
controlling compound provide [sic, provides]
