Appeal No. 1998-3322
Application No. 08/796,500
The subject matter on appeal relates to a thermosettable
pressure sensitive adhesive composition and to a method of
bonding a component to a surface using such a composition.
The composition includes a polymerization product, an epoxy
resin and a pigment wherein these ingredients and the amounts
thereof are selected such that the composition is capable of
undergoing a detectable color change upon reaching a pre-
determined level of cure. This appealed subject matter is
adequately illustrated by independent claims 21 (the method)
and 35 (the composition), and a copy of these claims taken
from the appellants’ brief is appended to this decision.
The references relied upon by the examiner as evidence of
obviousness are:

Claims 21-35 stand rejected under the first paragraph of
35 U.S.C. § 112 as being based upon a disclosure which fails
to satisfy the written description requirement of this
paragraph for the now claimed subject matter.
