Appeal No. 1995-2781
Application No. 07/804,868
Claims 1-6, 9-11, 14-16, 33-38, 41-43 and 46-51 are
rejected under 35 U.S.C. § 103 over JP’645.
JP’645 describes heat developable photographic elements
used in color image forming. JP’645 discloses silver halide
light sensitive layers (Page 13); dye emitting compounds (Page
15); binders (Page 22); and various types of heat solvents
(Pages 7-10). JP’645 does not disclose the calculated logP
for the solvents or the importance of solvents not washing out
during aqueous development.
According to the Examiner, JP’645 anticipates the use of
benzamide derivatives as heat solvents in color producing
systems, alternatively, it would have been obvious to use
these heat solvents in heat developable compositions.
(Examiner’s Answer, paragraph bridging pages 4 and 5). The
Examiner also states the compounds embraced by the instant
claim language are taught with respect to formula IV and that
JP’645 has chosen a different measure of
hydrophobic/hydrophillic character. (Examiner’s Answer, page
14, lines 17-20). We have not been directed to a correlation
between the argued different measures of
hydrophobic/hydrophillic character of JP’645 and the
calculated logP for the solvents required by the claims. That
