Pressure-Sensitive Adhesive for Pressure-Sensitive Adhesive Tape, Tape Cassette, and Tape Printer

摘要

There is provided a double-sided pressure-sensitive adhesive tape which includes a first pressure-sensitive adhesive layer formed by using any of different types of adhesive samples. Thereby the first pressure-sensitive adhesive layer is adjusted so as to satisfy conditions that, slow peel strength when a printing tape made of a PET film is peeled off from the substrate film of the double-sided pressure-sensitive adhesive tape by 5 mm at peel rate of 0.5 mm/minute is 0.45 N/20 mm or higher and storage modulus of the adhesive layer is in a range from 90.7 kPa to 435 kPa. By improving adhesiveness to the printing tape under environmental temperature from a low temperature to a normal temperature, the double-sided pressure-sensitive adhesive layer renders the printing tape less apt to peel off.
