Abstract

An adhesive tape cartridge including a housing and an adhesive tape roll is provided. The adhesive tape roll is disposed in the housing and winds an adhesive tape. The adhesive tape includes a first adhesive layer, a second adhesive layer, and a separation material layer. The first adhesive layer comprises an adhesive with a first pigment added. The second adhesive layer is disposed on one side of the first adhesive layer in a thickness direction and comprises an adhesive with a second pigment added. The separation material layer is disposed on the one side of the second adhesive layer in the thickness direction. A volume ratio of the second pigment in the second adhesive layer is smaller than a volume ratio of the first pigment in the first adhesive layer.

First claim

What is claimed is:

1. An adhesive tape cartridge comprising:
a housing; and
an adhesive tape roll that is disposed in said housing and winds an adhesive tape,
said adhesive tape comprising:
a first adhesive layer comprising an adhesive with a first pigment added, and a first surface on one side in a thickness direction;
a second adhesive layer that is disposed on the one side of said first adhesive layer in the thickness direction, said second adhesive layer comprising an adhesive with a second pigment added, a second surface in contact with the first surface, and a third surface opposite to the second surface in the thickness direction; and
a separation material layer that is disposed on a side of said second adhesive layer in the thickness direction, the separation material layer comprising a fourth surface in contact with the third surface of said second adhesive layer,

wherein a volume ratio of said second pigment in said second adhesive layer is smaller than a volume ratio of said first pigment in said first 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,
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 bonding force of said second adhesive layer is equal to or larger than 3 N/10 mm,
wherein the adhesive tape cartridge further comprises:
an ink-image receiving layer that comprises a fifth surface that ink is transferred to, and that is disposed opposite to said second adhesive layer with respect to said first adhesive layer in the thickness direction and has a transmittance of 20% or more; and
in said housing, an ink ribbon roll that winds an ink ribbon which transfers ink to the fifth surface of said ink-image receiving layer of the adhesive tape, and

wherein the fifth surface of said ink-image receiving layer is in contact with a sixth surface of said separation material layer in a roll shape being wound, the sixth surface being opposite to the fourth surface in the thickness direction.

2. The adhesive tape cartridge according to claim 1 , wherein the adhesive tape further comprises
a film layer that comprises an eighth surface in contact with a seventh surface disposed on another side of said first adhesive layer in the thickness direction.

3. The adhesive tape cartridge according to claim 2 , wherein the adhesive tape further comprises
a colored layer that has a transmittance of 20% or more, and comprises a tenth surface being in contact with a ninth surface of said film layer, the ninth surface being opposite to the eighth surface in the thickness direction.

4. The adhesive tape cartridge according to claim 2 , wherein an average particle diameter of said second pigment is smaller than an average particle diameter of said first pigment.

5. The adhesive tape cartridge according to claim 4 ,
wherein the average particle diameter of said second pigment is less than 30 μm, and
wherein the average particle diameter of said first pigment is equal to or greater than 40 μM.

6. The adhesive tape cartridge according to claim 5 ,
wherein the average particle diameter of said second pigment is less than 10 μm, and
wherein the average particle diameter of said first pigment is equal to or greater than 60 μM.

7. The adhesive tape cartridge according to claim 1 , wherein said first pigment and said second pigment are made of the same material as each other.

8. The adhesive tape cartridge according to claim 1 ,
wherein said first pigment is a glitter pigment, and
wherein said second pigment is a solid pigment or a glitter pigment.

9. The adhesive tape cartridge according to claim 1 , wherein said first pigment has a transmittance of 20% or more.

10. The adhesive tape cartridge according to claim 1 , wherein
said first pigment is a first glitter pigment;
said second pigment is a second glitter pigment; and
said first glitter pigment is one coating a surface of a core material with a colorant, wherein the core material is at least one of scaly mica, glass, alumina, and metal, and the colorant is at least one of titanium oxide, iron oxide, and a solid pigment.

11. The adhesive tape cartridge according to claim 1 , wherein the adhesive tape further comprises
a film layer that is disposed on another side of said first adhesive layer in the thickness direction.

12. The adhesive tape cartridge according to claim 11 , wherein the adhesive tape further comprises
a colored layer that has a transmittance of 20% or more, and comprises a seventh surface being in contact with an eighth surface of said film layer, and a ninth surface being in contact with a tenth surface of said film layer, the eighth surface opposite to the first surface in the thickness direction, the ninth surface lying in a side of said first adhesive layer.

13. A method of manufacturing a print label, comprising:
performing printing on the fifth surface of said ink-image receiving layer by ink of the ink ribbon by using the adhesive tape cartridge according to claim 1 ;
producing a print label by using said adhesive tape comprising said ink-image receiving layer after printing; and
peeling off the fourth surface of said separation material layer from said print label produced, and affixing the third surface of said second adhesive layer to an adherend.
