An article comprising an optical element, the optical element comprising: a) an optical film having a first major outer surface and a second major outer surface opposite the first major outer surface, wherein the optical film is selected from the group consisting of visible mirror films, color mirror films, solar reflective films, infrared reflective films, ultraviolet reflective films, reflective polarizer films including brightness enhancement films and dual brightness enhancement films, absorptive polarizer films, antireflective films, specular reflector films, linear polarizers and circular polarizers; b) a substrate wherein the substrate comprises a polymeric material, glass material, ceramic material, metal-containing material, or a combination thereof; and c) an optically clear pressure sensitive adhesive layer positioned between said first major outer surface of the optical film and the substrate, said pressure sensitive adhesive layer comprising a (meth)acrylate block copolymer comprising i. at least two A block polymeric units that are the reaction product of a first monomer composition comprising an alkyl methacrylate, an aralkyl methacrylate, an aryl methacrylate, or a combination thereof, each A block having a Tg of at least 50 °C, said (meth)acrylate block copolymer comprising 20 to 50 weight percent A block; and ii. at least one B block polymeric unit that is the reaction product of a second monomer composition comprising an alkyl (meth)acrylate, a heteroalkyl (meth)acrylate, a vinyl ester, or a combination thereof, said B block having a Tg no greater than 20 °C, said (meth)acrylate block copolymer comprising 50 to 80 weight percent B block. a) an optical film having a first major outer surface and a second major outer surface opposite the first major outer surface, wherein the optical film is selected from the group consisting of visible mirror films, color mirror films, solar reflective films, infrared reflective films, ultraviolet reflective films, reflective polarizer films including brightness enhancement films and dual brightness enhancement films, absorptive polarizer films, antireflective films, specular reflector films, linear polarizers and circular polarizers; b) a substrate wherein the substrate comprises a polymeric material, glass material, ceramic material, metal-containing material, or a combination thereof; and c) an optically clear pressure sensitive adhesive layer positioned between said first major outer surface of the optical film and the substrate, said pressure sensitive adhesive layer comprising a (meth)acrylate block copolymer comprising i. at least two A block polymeric units that are the reaction product of a first monomer composition comprising an alkyl methacrylate, an aralkyl methacrylate, an aryl methacrylate, or a combination thereof, each A block having a Tg of at least 50 °C, said (meth)acrylate block copolymer comprising 20 to 50 weight percent A block; and ii. at least one B block polymeric unit that is the reaction product of a second monomer composition comprising an alkyl (meth)acrylate, a heteroalkyl (meth)acrylate, a vinyl ester, or a combination thereof, said B block having a Tg no greater than 20 °C, said (meth)acrylate block copolymer comprising 50 to 80 weight percent B block. i. at least two A block polymeric units that are the reaction product of a first monomer composition comprising an alkyl methacrylate, an aralkyl methacrylate, an aryl methacrylate, or a combination thereof, each A block having a Tg of at least 50 °C, said (meth)acrylate block copolymer comprising 20 to 50 weight percent A block; and ii. at least one B block polymeric unit that is the reaction product of a second monomer composition comprising an alkyl (meth)acrylate, a heteroalkyl (meth)acrylate, a vinyl ester, or a combination thereof, said B block having a Tg no greater than 20 °C, said (meth)acrylate block copolymer comprising 50 to 80 weight percent B block.
