Appeal No. 1997-1414
Application 08/406,706
spectrally sensitized negative-acting silver halide photographic element containing an
anthraquinone compound which compound is said to control the sensitometric response
curve in the toe area, i.e., the part of the curve corresponding to the most sensitive crystals
or sensitive response of crystals in the photographic film.
All of the claims stand or fall together (Brief, page 9). Claim 1 is illustrative and reads
as follows:
1. An infrared spectrally sensitized negative-acting silver halide photographic
element comprising a hydrophilic colloidal binder containing a silver halide emulsion and
from 50 to 1000 milligrams of an anthraquinone per mole of silver halide.

The reference relied upon by the Board is:
Kirk-Othmer, Encyclopedia for Chemical Technology, vol. 17, pgs. 612, 626-28, (1982).
The rejections before us are:
I. Claims 1-10 stand rejected under 35 U.S.C. § 102 (b) as anticipated by, or in the
alternative under 35 U.S.C. § 103 as being obvious over Kretchman.2
2The appellants STATUS OF THE CLAIMS (Brief, page 5) inaccurately states that
claims 1-10 have been finally rejected alternatively under 35 U.S.C. §§ 102(e) and 35
§ U.S.C. 103.
