Appeal No. 95-4066
Application 07/963,189
The examiner's second stated rejection under 35 U.S.C. §
103 is founded on "appellants' admissions" considered with
Takahashi in further view of Hasegawa and Shindo. Having
discussed above all the prior art on which the examiner relies
here except for Hasegawa, we shall here limit our specific
discussion of the prior art to Hasegawa.
Hasegawa recognizes that a problem exists between the
organic dye recording layers of a compact disk and the metal
reflective layer. Specifically, Hasegawa recognizes that there
is poor adhesion between the metal reflective layer and the
organic dye layer. Hasegawa overcomes this problem by
including a layer of an organic heterocyclic compound
containing at least one of nitrogen or sulfur between the
recording layer and the reflective layer. Appellants' claims,
however, require that the recording layer and reflective layer
are coupled, one to the other. Still further, Hasegawa at best
only generically suggests silver-copper alloys as useful for
the reflective layer. The specific examples of alloys used by
Hasegawa include, in atomic percents: 60/40 gold/copper; 70/30
gold/copper; 70/30 gold/silver; and, 50/50 gold/silver. No
silver-palladium or silver-copper alloys in the atomic
