Appeal No. 2006-1931
Application No. 10/305,201
BACKGROUND
According to Appellants, the invention relates to an adhesive composition comprising an
aqueous dispersion. The composition of the invention is an aqueous dispersion of the reaction
product of (A) a fatty compound containing on average 1 to 10 of at least one functional group
consisting of -OH, -SH, -NH2, -C=C-, -COOH, anhydride groups or epoxide groups and wherein
the fatty compound contains at least 1 mole-% of at least trifunctional fatty compounds. The
fatty compound is reacted with (B) at least one monofunctional or polyfunctional compound
which is capable of reacting with the functional groups of the fatty compound. (Brief, pp. 4
and 5). The specification also discloses the reaction of components (A) and (B) results in the
formation of branched molecules, polymers and oligomers. According to the specification the
reactions are known for synthesis of polymers and include, inter alia, polyaddition,
polycondensation, transesterfication condensation reactions and grafting reactions. (Page 10).
Claim 16, which is representative of the claimed invention, appears below:
16. An adhesive composition of matter comprised of:
an aqueous dispersion of the reaction product of:
A) at least one fatty compound containing on average 1 to 10 of at least one
functional group selected from the group consisting of -OH, -COOH, -SH, -NH2,
-C=C-, epoxide and anhydride group in the fatty component, the fatty compound
containing at least 1 mole -% of at least trifunctional fatty molecules, with
B) at least one reactive compound selected from the group consisting of mono- or
polyfunctional compounds capable of reacting with the functional groups of the
fatty compounds, said reaction product having a number average molecular
weight of at least 1,500.
