Application No. 08/183,058
In rejecting claims 1 through 9 under 35 U.S.C. § 103,

al’s coated polymeric film comprises support film
such as polyester, cellulose ester e.g., cellulose
triacetate (column 1, lines 26-30) and antistatic
coating composition comprising binder, solvent and
antistatic compound. Cavallo et al’s antistatic
compounds includes appellants’ antistatic compounds
(column 4, line 12 to column 9, line 25) and binder
such as gelatin.
This finding is not disputed. The only argument raised by
appellants is that it would not have been obvious to employ an
organic solvent as the solvent of the antistatic coating
composition described in the Cavallo reference.
However, as correctly found by the examiner (Answer, page
5), the Cavallo reference states (column 13, lines 3-42):
The non-ionic surface active agents, the
fluorinated organic salts, the matting agents and
the surface modifying agents are used in amounts
sufficient to provide an antistatic effect. A
preferred amount of non-ionic surface active agents
ranges from about 10 to about 1000 mg/m , a more2
