Appeal No. 2006-0231 Παγε 2
Application No. 09/234,253
BACKGROUND
The present invention relates to chemical pulp or paper compositions. According
to Appellants, the pulp or paper compositions have reduced loss of brightness and
enhanced resistance to yellowing by virtue of the composition comprising certain
hindered amine derivatives. (Brief, p. 3). Representative claim 44, as presented in
Appellants’ Brief, is reproduced below:
44. A composition having reduced loss of brightness and enhanced
resistance to yellowing which comprises
(a) a pulp or paper, and
(b) an effective stabilizing amount of tris(N,N-
diethylhydroxylammonium) citrate.
The Examiner relies on the following references in rejecting the appealed claims:
SELTZER et al. (Seltzer) 5,051,511 Sept. 24, 1991
RODGERS et al. (Rodgers) 5,459,222 Oct. 17, 19951
Claims 1 to 11, 35 to 40 and 44 stand rejected under 35 U.S.C. 103(a) as
unpatentable over the combination of Seltzer and Rodgers. (Answer, pp. 3-4). We
affirm the rejection.
