1 REPRESENTATIVE CLAIM
2 The sole independent claim is as follows:
3 27. A method of preparing a flexible film laminate
4 comprising:
5 a) mixing an epoxy resin and a curative having at least one
6 active hydrogen contained in a functional group selected from the
7 group consisting of primary amino groups, secondary amino groups,
8 carboxyl groups and combinations thereof to form an adhesive
9 formulation, said epoxy resin and said curative having been
10 selected so as to maintain the viscosity of said adhesive
11 formulation for at least 20 minutes after mixing within the range
12 of 1,000 to 10,000 cps at 40°C and said adhesive formulation being
13 essentially free of solvent, water and isocyanate-functionalized
14 compounds;
15 b) applying the adhesive formulation to a surface of a first
16 substrate selected from the group consisting of metal foils and
17 polymeric films;
18 c) pressing said surface of said first substrate having the
19 adhesive formulation applied thereto against a surface of a second
