摘要：
An aqueous dispersion-type acrylic pressure-sensitive adhesive composition includes acrylic copolymer emulsion particles dispersed in an aqueous medium. The acrylic copolymer emulsion particles has a ratio (AN IN )/(AN SUR ) of 1 or more, wherein (AN IN ) is an amount of acid groups in the acrylic copolymer emulsion particles, and (AN SUR ) is an amount of acid groups on the surfaces of the acrylic copolymer emulsion particles, (AN IN ) and (AN SUR ) being calculated from a titration curve of potentiometric titration performed by adding an inorganic base solution to an acidic sample dispersion solution containing the acrylic copolymer emulsion particles dispersed in ion exchange water. A pressure-sensitive adhesive tape which strongly adheres to an adherend and has excellent removability can be formed using the aqueous dispersion-type acrylic pressure-sensitive adhesive composition.
