Abstract:
1. An optically clear laminate comprising: a first substrate having at least one major surface; a second substrate having at least one major surface; and a cloud point-resistant, optically clear adhesive composition situated between and in contact with at least one major surface of the first substrate and at least one major surface of the second substrate, wherein the optically clear adhesive composition is prepared by polymerizing a precursor mixture, the precursor mixture comprising: wherein the hydrophilic polymeric compound has an average molecular weight (M n ) of greater than about 500 and includes poly(ethylene oxide) segments, wherein the laminate has a haze value of less than 5% and an average transmission between 450 nanometers and 650 nanometers of greater than about 85% after it is placed in an environment of at least 70° C. and 90% relative humidity for 72 hours, cooled to room temperature, and measured.
