Appeal No. 96-2505
Application No. 08/122,417
This is a decision on an appeal from the final rejection of
claims 25 through 64 which are all of the claims remaining in the
application.
The subject matter on appeal relates to an aqueous polymer
dispersion reactive resin component for a two-component reactive
laminating adhesive system comprising OH-functional polyurethane
prepolymers produced by a particular process. The process
comprises reacting a polyol component and compounds containing at
least two isocyanate-reactive groups with a stoichiometric excess
of an isocyanate component comprised of at least 20% by weight
tetramethyl xylylene diisocyanate to produce polyurethane
prepolymers with remaining NCO groups followed by dispersing
these prepolymers in water and at least partially reacting the
remaining NCO groups of the prepolymers with aminoalcohols. This
appealed subject matter is adequately illustrated by independent
claim 25, a copy of which taken from the appellants' brief is
appended to this decision.
The references relied upon by the examiner in the rejections
before us are:
