Abstract: An article (100) for a display device includes a diffraction grating film (102), a first optically clear adhesive layer (120), and a second optically clear adhesive layer (130). The diffraction grating film includes a base layer (104) and a plurality of microstructures (106) projecting from the base layer. The base layer defines a non-structured surface of the diffraction grating film and the plurality of microstructures define a structured surface of the diffraction grating film opposite to the non-structured surface. The first optically clear adhesive layer is disposed on the structured surface of the diffraction grating film. The second optically clear adhesive layer is disposed on the non-structured surface of the diffraction grating film.

Abstract: An optically clear adhesive composition is provided that is derived from precursors that include from about 0 to about 50 parts by weight of an alkyl acrylate having 1-11 carbon atoms in the alkyl group, from about 40 to about 95 parts by weight of an alkyl acrylate having 12 or more carbon atoms in the alkyl group, from about 5 to about 20 parts by weight of a copolymerizable polar monomer, and an initiator. The adhesive composition has a moisture content of less than about 1.0% when the adhesive is positioned in between two release films and placed in an environment of 85 C/85% relative humidity for 72 hours and then cooled down to room temperature. Moreover, when the adhesive composition is placed between two transparent substrates and made into a laminate, the laminate has a haze value of less than about 5% after the laminate is placed in an environment of 85 C/85% relative humidity for 72 hours and then cooled down to room temperature.

Abstract: Curable adhesive compositions are provided that can be cured using ultraviolet or visible light radiation. These curable adhesive compositions, which contain a curable (meth)acrylate copolymer, have a creep compliance that is less than 5(10−4) inverse Pascals at 25° C., a creep compliance that is greater than 1(10−3) inverse Pascals at 70° C., and a shear storage modulus greater than 40 kiloPascals when measured at 25° C. at a frequency of 1 radian/second.
