Printing tape with improved resistance to temperature and water

A method of producing a printing tape cassette, the method comprising:

• preparing a cassette case having a first surface, a second surface facing the first surface, and a third surface connecting the first surface to the second surface, a combination of the first surface, the second surface, and the third surface defining an internal space, the cassette case being used for being attached to a cassette housing section of a printing device;
• preparing a first tape, the first tape comprising a heat-sensitive layer, a first protective layer, and a second protective layer, the first protective layer being provided on the heat-sensitive layer and the second protective layer being provided on a side of the heat-sensitive layer opposite the first protective layer, the heat-sensitive layer being used for producing color at temperatures within a prescribed range, the first protective layer allowing light to pass therethrough, the second protective layer containing epoxy polyester-based resin;
• preparing a second tape comprising a first adhesive layer and a base material, the first adhesive layer being made by using emulsion-type adhesive compounded with tackifying resin and containing acrylic polymer and rubber-based adhesive, the first adhesive layer having one surface and another surface opposite to the one surface, the base material being adhered to the one surface of the first adhesive layer;
• and
• combining both of the first tape and the second tape with the cassette case such that both of the first tape and the second tape are accommodated in the internal space, the first tape being wound in a roll and the second tape being wound in a roll in such a manner that, when the first tape is fed from the roll of the first tape and printed by the printing device and the second tape is fed from the roll of the second tape, the first tape is joined to the second tape such that the another surface of the first adhesive layer in the second tape is adhered to the second protective layer of the printed first tape to allow the second protective layer of the printed first tape to be disposed between the first adhesive layer and the heat-sensitive layer.
