Zusammenfassung:	A viscous adhesive tape comprises a tack layer containing a first acrylic resin having an acid value of 30 to 100 mg KOH/g and a second acrylic resin having an acid value of 0 to 10 mg KOH/g, wherein the ratio between the first acrylic resin and the second acrylic resin is, (First acrylic resin):(Second acrylic resin)=85:15 to 65:35, and the first acrylic resin and the second acrylic resin have a semi-interpenetrating polymer network structure.
