Abstract
Adhesive tapes, articles containing the adhesive tapes, methods of making the adhesive tapes, and uses of the adhesive tapes are described. The adhesive tape is stretch releasable and can be used to couple two substrates together. The adhesive tape can be removed easily to separate the two substrates for any reason. The adhesive tape includes a backing layer and at least one pressure-sensitive adhesive layer adjacent to the backing layer. The backing layer contains a first acrylic copolymer. Each pressure-sensitive adhesive layer contains a second acrylic copolymer plus inorganic particles that are dispersed or suspended in the second acrylic copolymer.
