Application No. 08/141,457
compounds have very low degradation effect to dye images. See column 5, lines 3-7.
Moreover, the compounds when incorporated into photosensitive materials do not injure
the photographic properties, do not reduce the photosensitivity of the materials and
inhibit fog formation. See column 5, lines 31-53. Accordingly, we conclude that these
compounds are stabilizers
According to the examiner, Okamura similarly discloses a development inhibitor
precursor compounds containing a sulfide group and a sulfone group within the scope of
the claimed subject matter. See structural formula (I) column, 2, lines 5-10.
Significantly, the appellants have not challenged the examiner’s finding. The inhibitor
compounds are present in photographic elements. See column 1, line 52 to column 2,
line 15. The compound may be added to any photographic layer. See column 3, lines
11-15. The amount of the compound added is disclosed at column 3, lines 29-31.
Okamura discloses that the compounds of the invention are stable while being maintained
in a light sensitive material and give little or not deterioration in photographic properties.
Moreover, the compounds can inhibit fog. See column 9, lines 9-32. Accordingly, we
conclude that these compounds are likewise stabilizers.
J61/250641 discloses sulfide compounds which are effective magenta coupler
pigment image stabilizers for photographic material. See page 30. The magenta couplers
include compounds having pyrazolone moieties and specifically includes those of Lestina.
