Pressure-sensitive adhesive optical film and image display
A pressure-sensitive adhesive optical film includes: an optical film; and a pressure-sensitive adhesive layer laminated on at least one side of the optical film with an anchor layer interposed therebetween, wherein the anchor layer has a thickness of 5 to 300 nm, the pressure-sensitive adhesive layer has a thickness of 5 to 50 μm, at least one of the anchor layer and the pressure-sensitive adhesive layer is made from a ammonia-containing water-dispersible material, the layer made from the ammonia-containing water-dispersible material contains ammonia in an amount of 10 ng or more per 1 cm 2 of the pressure-sensitive adhesive optical film, wherein the amount is a measurement derived from the layer, and the pressure-sensitive adhesive optical film contains ammonia in a total amount of 2000 ng or less per 1 cm 2 of the pressure-sensitive adhesive optical film. The pressure-sensitive adhesive optical film has good appearance and high durability.
1. A pressure-sensitive adhesive optical film, comprising:
