Appeal 2006-2950
Application 10/036,126
I. APPEALED SUBJECT MATTER
The subject matter on appeal relates to compositions useful for
“forming an electrically conductive antistatic layer.” See the Specification
9. These compositions are said to include “aqueous mixtures of an
electronically conductive polymer, a neutral charge conductivity enhancer
and a hydrophilic polymeric binder.” See the Specification 9. The
electronically conductive polymer is defined to include the myriad of
polymers described at pages 10 and 11 of the Specification. Some of the
examples are substituted or unsubstituted thiophene-containing polymers
and polyanions. See the Specification 11. The neutral charge conductivity
enhancer is defined to include the myriad of compounds listed at page 13 of
the Specification. “Particularly preferred neutral charge conductivity
enhancers are: sugar and sugar derivatives… sugar alcohols such as
sorbitor...alcohols such as ethylene glycol, glycerol…” See the Specification
13. The hydrophilic polymeric binder is defined to include the myriad of
compounds listed at page 12 of the Specification. The Specification
specifically states that:
Polymeric film-forming hydrophilic binders useful in
compositions for electrically conductive compositions
according to this invention can include, but are not limited to,
water-soluble or water-dispersible hydrophilic polymers such as
gelatin, gelatin derivatives, maleic acid anhydride copolymers,
cellulose derivatives…synthetic hydrophilic polymers…that
would be readily apparent to one skilled in the imaging arts.
Gelatin and gelatin derivatives are the preferred binders in the
practice of this invention.
Specification 12-13.
