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] -6-Page: Previous 1 2 3 4 5 6 7 8 9 10 NextLast modified: November 3, 2007
