Abstract:
1. Adhesive for an adhesive tape, the adhesive being applied on a first surface of a substrate film of the adhesive tape so as to form a first adhesive layer which is stuck onto a polyethylene terephthalate film, wherein the adhesive is adjusted so as to satisfy conditions that, a first double-sided adhesive tape, in which the first adhesive layer and a second adhesive layer formed by applying the adhesive on a second surface of the substrate film are provided, is used and a peeling length of the polyethylene terephthalate film from the first adhesive layer when the first double-sided adhesive tape is stuck around an outer circumference of a polypropylene tube having an outer diameter of φ6 mm with an end portion of the first double-sided adhesive tape overlapped by approximately 5 mm is 1 mm or shorter, the polypropylene tube being stored for 24 hours under an environment of a temperature of 50 degrees C. and a humidity of 90%, wherein a number of peeling segments in each of which whole width of the polyethylene terephthalate film of a printed tape peeled-off from the first adhesive layer in a half cut portion when a tape cassette in which a second double-sided adhesive tape formed by adhering a release sheet on the second adhesive layer applied on the second surface, the polyethylene terephthalate film and an ink ribbon are assembled is stored and kept for two hours under an environment of −5 degrees C., twenty half cuts are continuously provided at an interval of 20 mm while the printed tape is formed by adhering the first adhesive layer of the second double-sided adhesive tape to the polyethylene terephthalate film on which printing is conducted by the ink ribbon, and the number of peeling segments immediately counted under the environment of a temperature of −5 degrees C. is 10 or lower.
