Appeal No. 1997-0311
Application No. 08/340,017
Appellants also maintain at page 4 of the Brief that
there is no requirement in Gamon that suggests the solubility
requirement of claimed component (C) in component (A).
However, since appellants do not dispute the examiner's
finding that Gamon teaches organopolysiloxanes and
organopolysiloxane resins that correspond to the claimed
components, we agree with the examiner that it reasonably
follows that the organopolysiloxane resins of Gamon would be
at least partly soluble in the organopolysiloxane having
hydroxyl groups in the terminal units. We note that
appellants' specification, at page 7, attaches no criticality
to the amount of organopolysiloxane resin employed, i.e., from
0.1 to 100 parts by weight per 100 parts by weight of
organopoly-siloxane (A).
We are also not persuaded by appellants' argument that a
high degree of selection from the Gamon disclosure is required
to arrive at the claimed composition. Adhesion promoters are
conventional additives for dispersions of the type claimed and
disclosed by Gamon, and the only class of compounds disclosed
by Gamon as an adhesion promoter is one encompassing amino-
functional silanes, all of which meet the claimed requirement
