<p><P>PROBLEM TO BE SOLVED: To provide a double-sided adhesive tape which strongly adheres to an adherend substrate such as a plastic or a metal, and can be peeled without residue or destruction of a nonwoven fabric which is a supporting substrate, without a particular treatment such as heating, upon peeling of the tape after being attached for a long period of time. <P>SOLUTION: The double-sided adhesive tape comprises a nonwoven fabric substrate and an adhesive layer composed of an acrylic adhesive composition, wherein the nonwoven fabric substrate is a nonwoven fabric substrate with fixation of 3-30 mass% acrylic copolymer emulsion having a glass transition temperature of≤-10°C to a nonwoven fabric having a tensile strength of 5-45 N/20 mm, the acrylic adhesive composition is a water-dispersible emulsion-type acrylic adhesive composition of the acrylic copolymer containing 2-ethylhexyl acrylate, a nitrogen-containing vinyl monomer, an ethylenic unsaturated monomer having a carboxyl group, and the adhesive layer has a storage modulus at frequency of 1 Hz at 30°C of 6×10<SP>4</SP>to 1×10<SP>5</SP>Pa. The double-sided adhesive tape has strong adhesive force and excellent removability. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
