Appeal No. 2005-0622
Application 09/911,279
is not an argument as to why the claims are separately
patentable. See 37 CFR ' 1.192(c)(7)(1997). The claims,
therefore, stand or fall together. Accordingly, we limit our
discussion to one claim, i.e., claim 1.
Held discloses an inkjet ink composition comprising an
aqueous carrier medium, a colorant, and 2.5-6 wt%, based on the
total weight of the ink composition, of a mixture of at least one
siloxane surfactant and at least one fluorinated surfactant of
the formula [R(f)Q]nA, where R(f) is a perfluoroalkyl group
having 6 to 22 carbon atoms, Q is a divalent bridging group, A is
a water soluble group, and n is 1 or 2, wherein the siloxane
surfactant is present in the amount of 10-75 wt%, based on the
total weight of the surfactant mixture (col. 1, lines 41-62).
Caiger discloses a radiation curable inkjet ink composition
comprising 80-95 wt%, based on the total composition, of
polyfunctional alkoxylated and/or polyfunctional polyalkoxylated
acrylate monomer material, a photoinitiator, and optionally other
components which can be a colorant and a surfactant (col. 2,
lines 15-20; col. 3, lines 19-21 and 41-43). The exemplified
surfactant is Fluorad7 FC430 which, the appellants and the
examiner agree, is a C8 fluorinated surfactant (brief, page 20;
answer, page 5).
