This is an appeal from the final rejection of claims 6-9
and 11-20, all the claims remaining in the present
application. Claims 6 and 14 are illustrative:
6. An aqueous-based paper or paper board coating
composition consisting essentially of a pigment, a binder, and
a lubricant additive selected from the group consisting of a
polyoxyalkylene mono- and di-ester of phosphoric acid, a
polyoxyalkylene mono- and di-ester of a phosphoric acid salt,
and a mixture thereof.
14. The process of applying an aqueous-based coating
composition consisting essentially of a pigment and a binder
to a rapidly moving paper or paper board web consisting of
contacting said web with a lubricant additive selected from
the group consisting of a polyoxyalkylene mono- and di-ester
of phosphoric acid, a polyoxyalkylene mono- and di-ester of a
phosphoric acid salt, and a mixture thereof.
The examiner relies upon the following references as
evidence of obviousness:

Nikoloff et al. (Nikoloff) 4,766,015 Aug. 23, 1988
Appellants' claimed invention is directed to an aqueous-
based composition for coating paper or paper board consisting
essentially of a pigment, a binder and a polyoxyalkylene
phosphate ester. The polyoxyalkylene phosphate ester is
employed as a lubricant. Appealed claim 14 is directed to a
