Abstract

See full text

A pressure-sensitive adhesive layer for an optical film made from an aqueous dispersion-type pressure-sensitive adhesive composition, wherein the aqueous dispersion-type pressure-sensitive adhesive composition is an aqueous dispersion comprising a water-dispersible (meth)acryl-based copolymer (A) having a glass transition temperature from −55° C. to less than 0° C.; and a water-soluble or water-dispersible component (B) having a glass transition temperature of 0° C. or more, a mixture ratio (A)/(B) is in the range of 50-97/3-50, the component (B) forms domains with maximum lengths between 1 nm and 200 nm in a resin component made of the (meth)acryl-based copolymer (A), and the pressure-sensitive adhesive layer has a haze value (H20) of 1% or less when having a thickness of 20 μm. The pressure-sensitive adhesive layer for an optical film, which is made from an aqueous dispersion-type pressure-sensitive adhesive composition has good reworkability or recyclability, and has a sufficient level of durability.
