PROBLEM TO BE SOLVED: To provide an adhesive tape which can reduce the content of an organic solvent and has excellent impact resistance and waterproofness.SOLUTION: An adhesive tape comprises a foam substrate and an adhesive layer. The foam substrate has a 25% compression strength of 400 kPa or lower, and the adhesive layer is composed of a water dispersion type acrylic adhesive composition containing an acrylic copolymer. The content of acrylic acid in the monomer components constituting the acrylic copolymer is 4 mass% or lower, and the amount of an emulsifier used in the acrylic copolymer is 0.1-2 pts. mass to 100 pts. mass of the monomers constituting the acrylic copolymer. The adhesive tape realizes excellent impact resistance and waterproofness. |
