    Abstract: Provided is a PSA sheet with low toluene and total volatile organic compound (TVOC) emissions as well as low unpleasant odor level felt by users. The PSA sheet comprises a PSA layer formed of a PSA composition comprising an acrylic polymer emulsion and a tackifier resin emulsion; the toluene and TVOC emissions are at most 20 μg and at most 150 μg, respectively; in a sensory test, 90% of participants evaluate that the unpleasantness of odors emitted from the PSA sheet is less than that of toluene at a prescribed concentration.

    Abstract: The present invention provides a double-sided adhesive tape for fixing a decorative sheet for speaker, which includes a nonwoven fabric substrate, an acrylic pressure-sensitive adhesive layer A disposed on one side of the nonwoven fabric substrate and an acrylic pressure-sensitive adhesive layer B disposed on the other side of the nonwoven fabric substrate, in which the adhesive tape has a tensile strength in the tape flow (MD) direction of 8 N/10 mm or more and a tensile length in the width (TD) direction of 8 N/10 mm or more. The double-sided adhesive tape is excellent in the adhesion performance to a housing and a decorative sheet for speaker and at the same time, has excellent releasability ensuring that when separating the decorative sheet portion, smooth separation can be attained without leaving a residue of tape or pressure-sensitive adhesive on the housing portion.

    Abstract translation: 本发明提供一种用于固定扬声器用装饰片的双面胶带,其包括无纺布基材,设置在无纺织物基材一侧的丙烯酸类粘合剂层A和丙烯酸类压敏粘合剂层 B布置在无纺布基材的另一侧,其中胶带的带流(MD)方向的拉伸强度为8N / 10mm以上,宽度(TD)方向的拉伸长度为8 N / 10 mm以上。 双面胶带对于壳体和用于扬声器的装饰片的粘合性能优异,同时具有优异的剥离性,确保在分离装饰片部分时可以实现平滑分离而不会留下胶带残留物 或压敏粘合剂在壳体部分上。
