Abstract:
1. A method of making a display assembly, the method comprising: (a) attaching a first substrate and a second substrate with an optically clear heat activated adhesive to form a laminate, wherein the adhesive has a shear storage modulus of about 5×10 wherein each of the first and second substrate has opposing major surfaces, wherein at least one of the first and second substrates has a three-dimensional surface topography covering at least a portion of one of its major surfaces; and wherein at a heat activation temperature, the adhesive is pressure sensitive; and (b) heating the laminate to the heat activation temperature of the adhesive, causing the adhesive to flow, wherein the activation temperature is greater than 40° C. and less than 120° C., wherein the adhesive is selected from the group consisting of thermally reversible cross-linkable adhesives and adhesives that are capable of being post cross-linked using irradiation, thermal or moisture curing; and wherein after heating the laminate, the adhesive conforms to the three-dimensional surface topography.
