    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.

    摘要： Disclosed is a double-sided adhesive tape including a nonwoven fabric substrate and an adhesive layer composed of an acrylic adhesive composition. The nonwoven fabric substrate is obtained by fixing an acrylic copolymer having a glass transition temperature of -10°C or lower to a nonwoven fabric having a tensile strength of 5 to 45N/20 mm in both the MD direction and the TD direction. The adhesive layer has a storage modulus at a frequency of 1 Hz at 30°C of 6x10 4 to 1x10 5 Pa. This double-sided adhesive tape has strong adhesive force and excellent removability.
