Appeal No. 96-0044
Application 08/014,136
The subject matter on appeal is directed to a coating composition comprising an
intrinsically electrically conductive polymer, a binder, a solvent and an additive having low
adhesion to metal. The coating composition is said to be useful in metal transferration
processes to coat a transfer metallization plastic film whereby a metal layer deposited on
the coated plastic film is transferred to a second carrier, thus allowing the coated plastic
film to be reused.
Appellants indicate and argue that the claims do not stand or fall together. For
purposes of this decision, we find it necessary to address claim 1, which is the only
independent claim. Claim 1 reads as follows:
1. A coating composition for a transfer metallization plastic film comprising an intrinsically
electrically conductive polymer in an amount effective to provide antistatic properties when
coated onto the plastic film;
one or more additives which have a low adhesion to a metal layer in an amount
effective to allow release of the metal layer from the plastic film;
one or more binders in an amount effective to improve the adhesion of the coating
to the surface of the plastic film, wherein the binder is other than the conductive polymer
and the additive; and
a solvent to dissolve, swell, or disperse the electrically conductive polymer, binder,
and the additive.
