Abstract
Provided is an optical PSA composition that can be easily peeled using an aqueous liquid such as water and has sufficient adhesive strength. An optical PSA composition comprising an acrylic polymer is provided. The PSA composition comprises at least one species of compound A selected among surfactants and compounds having polyoxyalkylene backbones. The monomers forming the acrylic polymer comprises less than 20 wt % alkoxyalkyl (meth)acrylate and less than 20 wt % alkoxypolyalkylene glycol (meth)acrylate. Alternatively, the compound A content is less than 1 part by weight to 100 parts by weight of the acrylic polymer.
