Appeal No. 95-3088
Application 08/059,983
obviousness. As noted by appellant, Wernicke teaches that the
washing step may be eliminated without adversely affecting the
quality if (1) an N,N-dialkyl-p-phenylenediamine compound is used
as the sole developer, (2) the first development bath contains a
compound which prevents developer oxidation products from
reacting with the color couplers and (3) the silver halide layers
have a chloride content of at least 80 mole % (col. 2, lines 17-
39). We agree with appellant that Wernicke's teachings are very
specialized and cannot be combined with the other references in
any way that would suggest the claimed invention, which requires
hydroquinone sulfonic acid as the developer.
The decision of the examiner is reversed.
