Abstract: A double-sided pressure-sensitive adhesive tape is used for fixing decorative panels and includes a pressure-sensitive adhesive layer containing bubbles and/or hollow microspheres. The pressure-sensitive adhesive layer is preferably formed from an acrylic pressure-sensitive adhesive, particularly an active-energy-ray-curable acrylic pressure-sensitive adhesive. The double-sided pressure-sensitive adhesive tape for fixing decorative panels preferably has a toluene emission of 15 µg/g or less and preferably has a surface lightness L* of 60 to 30. The adhesive tape can be a double-sided pressure-sensitive adhesive tape for fixing decorative panels, which excels in conformability to curved surfaces and bumps, resilience resistance, and adhesiveness and which may thereby show excellent adhesive properties even when used for fixing a decorative panel to an adherend of a complicated shape with a curved surface or bumps or for fixing a narrow decorative panel to an adherend.
