Aqueous dispersion type pressure-sensitive adhesive composition and pressure-sensitive adhesive product

摘要

An aqueous dispersion type pressure-sensitive adhesive composition contains an acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type and at least one hydrophilic polymer selected from the group consisting of polyalkylene glycols, polyvinylpyrrolidone, poly(vinyl alcohol)s, and poly((meth)acrylic acid), the amount of the hydrophilic polymer being from 0.5 to 15 parts by weight per 100 parts by weight, on a solid basis, of the acrylic or rubber-based pressure-sensitive adhesive composition of the aqueous dispersion type, and a pressure-sensitive adhesive product has a pressure-sensitive adhesive layer formed from the aqueous dispersion type pressure-sensitive adhesive composition.
