Appeal 2007-1021
Application 10/834,652
The Appellants claim a composite structure comprising a first layer
and a second layer which comprises the reaction product of an isocyanate
component and a resin component reactive with the isocyanate component at
ambient temperature wherein the resin component includes an isocyanate-
reactive component having a nominal functionality of at least 3, an amine-
based catalyst active at ambient temperature that initiates an exothermic
reaction between the isocyanate component and the isocyanate-reactive
component, and a temperature-activated catalyst different from the amine-
based catalyst that is active at a temperature greater than the ambient
temperature. The Appellants also claim the previously described resin
component as well as a process for making the composite structure.
Representative claim 1 reads as follows:
1. A composite structure comprising:
(A) a first layer comprising a styrenated unsaturated polyester
wherein said first layer is a show surface of said composite structure; and
(B) a second layer comprising the reaction product of:
(I) an isocyanate component; and
(II) a resin component reactive with said isocyanate component
at ambient temperature comprising:
(a) an isocyanate-reactive component having a nominal
functionality of at least 3;
(b) an amine-based catalyst active at ambient
temperature that initiates an exothermic reaction between said isocyanate
component and said isocyanate-reactive component; and
