摘要:
A double-sided pressure-sensitive adhesive tape for fixing a decorative sheet for speaker, which is extremely small in the generation of VOC, is provided. The present invention relates to a double-sided pressure-sensitive adhesive tape for fixing a decorative sheet for speaker of the invention, comprising a substrate, a pressure-sensitive adhesive layer A disposed on one side of the substrate and a pressure-sensitive adhesive layer B disposed on the other side of the substrate, wherein a total volatile organic compound amount (TVOC amount) is 300 μg/g or less, a diffusion amount of formaldehyde is 3 μg/m3 or less, and a diffusion amount of toluene is 10 μg/g or less. A base polymer of the layer A is preferably formed by solution polymerization using a solvent selected from a solvent composed of only ethyl acetate and a mixed solvent having a proportion of ethyl acetate of 90% by weight or more.
