appellant that the aforementioned rejection is not well
founded. Accordingly, we will not sustain this rejection.
Chen discloses the use of antistatic layers comprising:
(1) a hydrophilic binder such as gelatin; (2) a surface active
polymer including polymerized oxyalkylene monomers and (3) a
fluorine containing inorganic salt selected from a specified
group thereof (column 1, line 55 to column 2, line 40). The
photographic element to be coated by such antistatic layer may
comprise a silver halide emulsion (column 6, lines 3-32).
Timmerman discloses the use of solvent-resistant polymer
beads in a covering layer for a recording material containing
a support, a silver halide containing emulsion layer and a
colloidal silica containing antistatic layer (column 4, lines
27-39). Timmerman further teaches that microcracking in dry
state antistatic layers consisting of colloidal silica may be
counteracted by adding a synthetic clay to such an antistatic
layer.
The examiner correctly recognizes that: (1) Chen does not
disclose the use of a synthetic clay in the protective layer
(answer, page 2, last line); and (2) Timmerman's teachings
regarding the use of a synthetic clay and the advantages
