moieties attached to a polymeric backbone through N-
heterocycles or N,N-dimethylaminoethyl methacrylate moieties,
such that the
N-heterocycles or N,N-dimethylaminoethyl methacrylate moieties
are N-quaternized by the guanyl hydrazone moieties (abstract;
structures in columns 2-5). Farooq does not disclose 1
appellant’s polymeric backbone or attachment of the guanyl
hydrazone salt moieties to the backbone through appellant’s

Breton discloses an ink composition which includes, for
the purpose of reducing the drying time of the ink while
maintaining good print quality, an additive which can be a
polyether diamine based on a predominantly polyethylene oxide
backbone (col. 2, lines 25-35; col. 4, lines 17-64). The
polyether diamine can be Jeffamine ED-2001 (col. 4, line 61), ®
which is one of the materials which can be used to form the
backbone of appellant’s mordant (specification, page 8, lines
12-21).
The examiner uses Delfino to link the Farooq and Breton
