having a shortage of formaldehyde (the resorcinolic resin).
The first aspect of the invention as presented in appealed
claims 1-19 involves a method of preparing an aqueous adhesive
composition by mixing first and second components respectively
comprised of the resole resin and the resorcinolic resin
wherein the quantity of a methylene donor which is a part of
the resole resin component and a resole curing catalyst which
is a part of the resorcinolic resin component “is sufficient
to cause curing of the resin of the other component”. See
appealed claim 1. Appealed claims 23-27 are directed to an
alkaline adhesive composition prepared by the mixing of the
first and second resin components referred to above. Thus,
the appealed composition claims are “product-by-process”
claims.
The examiner’s rejections of both the method claims and
the composition claims are based principally on the
disclosures in Daily. In his final rejection, the examiner
correctly characterized the Daily reference as disclosing a
method for preparing an adhesive composition by mixing two
respective resin components comprising a resole resin and a
resorcinolic resin. The examiner also correctly found that
