Abstract
A process comprising a) mixing i) an isocyanate reactive component that contains from 2 to 100 weight percent of an aminobenzoate terminated composition wherein the isocyanate reactive component does not contain a solvent; and ii) an isocyanate terminated component having an isocyanate functionality of from 2 to 6 wherein the isocyanate terminated component does not contain a solvent; at a stoichiometric ratio of NCO to reactive hydrogen in the range of from 0.9 to 2.5; to form an adhesive composition; b) applying the adhesive composition to a primary substrate; and c) laminating the primary substrate with a secondary film to form a laminate structure, is disclosed. The laminate structure can be used as a laminating adhesive.
