Appeal No. 1997-2271
Application 08/588,969
THE INVENTION
Appellants’ claimed invention is directed toward an
optical recording element which contains a specified
metallized azo-ether dye having an alkoxy substituent at the
2-position of a phenyl nucleus, and toward a method for
recording optical information using this recording element.
Claim 1 is illustrative and reads as follows:
1. An optical recording element comprising in the
following order, a light transmitting substrate, a recording
layer containing a dye and a light reflective layer wherein
the dye is:
(a) selected so that the real part of the complex
reflective index (N) of the unwritten light absorptive layer
measured with 780 nm light source is greater than 2.0 and the
imaginary part (k) is 0.01 to 0.10 and
(b) a metallized azo-ether dye having an azo group
linking a 3-hydroxy-pyridine nucleus to a phenyl nucleus
wherein the phenyl nucleus has an alkoxy substituent at its 2-
position. [2]
as in the parent case are applied, we agree with appellants
(brief, page 3) and the examiner (answer, page 1) that, in
effect, the claims have been twice rejected and that,
therefore, we have jurisdiction to decide the appeal.
2There is no clear antecedent basis for “the unwritten
light absorptive layer” in claims 1 and 5. Appellants and the
examiner should provide clear antecedent basis for this term.
