Abstract:
A pressure-sensitive adhesive layer for an optical film of the invention, which is formed by applying an aqueous dispersion pressure-sensitive adhesive including an aqueous dispersion containing at least a base polymer dispersed in water, and then drying the applied aqueous dispersion pressure-sensitive adhesive, has a content of residual monomer in the pressure-sensitive adhesive layer is 5 to 100 ppm per 1 g of the solid of the pressure-sensitive adhesive layer. The pressure-sensitive adhesive layer for an optical film has high durability so that foaming and peeling can be suppressed even under high temperature or high humidity environment.
