Adhesive tape cartridge, adhesive tape roll, and manufacturing method of adhesive tape roll

An adhesive tape cartridge comprising:

• a housing;
• and
• an adhesive tape roll that is disposed in said housing and winds a double-faced adhesive tape,
• said double-faced adhesive tape comprising:
• a base material layer;
• a first adhesive layer that is disposed on one side of said base material layer in a thickness direction, said first adhesive layer comprising an adhesive with a first pigment added, and a first surface opposite to said base material layer in the thickness direction;
• a second adhesive layer that is disposed on one side of said first adhesive layer in the thickness direction, said second adhesive layer comprising an adhesive with a second pigment added, and a second surface in contact with the first surface;
• a third adhesive layer that is disposed on another side of said base material layer in the thickness direction, said third adhesive layer comprising an adhesive, and a third surface opposite to said base material layer in the thickness direction;
• and
• a separation material layer that is disposed on a side of said third adhesive layer in the thickness direction, the separation material layer comprising a fourth surface to make contact with the third surface of said third adhesive layer,
• wherein the third surface adheres to an adherend at a time that the fourth surface of said separation material layer is separated from the third surface of said third adhesive layer,
• wherein a volume ratio of said first pigment in said first adhesive layer is greater than a volume ratio of said second pigment in said second adhesive layer,
• wherein said first adhesive layer is in contact with said second adhesive layer,
• wherein said second adhesive layer is in contact with said separation material layer in a roll shape being wound,
• wherein the volume ratio of said first pigment in said first adhesive layer is 1.5 times or more the volume ratio of said second pigment in said second adhesive layer,
• wherein the volume ratio of said first pigment in said first adhesive layer is 5% or more and 50% or less,
• wherein the volume ratio of said second pigment in said second adhesive layer is more than 5% and 50% or less,
• wherein a thickness of said second adhesive layer is smaller than a thickness of said third adhesive layer,
• wherein a thickness of said first adhesive layer is smaller than the thickness of said third adhesive layer,
• wherein a sum of the thickness of said first adhesive layer and the thickness of said second adhesive layer is greater than the thickness of said third adhesive layer,
• wherein a bonding force of said second adhesive layer is equal to or larger than 3 N/10 mm,
• wherein the adhesive tape cartridge further comprises, in said housing:
• a cover film roll that winds a cover film comprising a sixth surface to be bonded to a fifth surface of said second adhesive layer of said double-faced adhesive tape, the fifth surface being opposite to the second surface in the thickness direction;
• an ink ribbon roll that winds an ink ribbon that transfers ink to the sixth surface of said cover film fed out from said cover film roll;
• and
• a colored layer that is disposed on said one side of said base material layer in the thickness direction and disposed on another side of said first adhesive layer in the thickness direction, said colored layer comprising an eighth surface in contact with a seventh surface of said base material layer, and a ninth surface in contact with a tenth surface of said first adhesive layer, the seventh surface being opposite to said third adhesive layer in the thickness direction, and the tenth surface laying on a side of said third adhesive layer.
