Abstract

This disclosure discloses an adhesive tape having a dimension in a thickness direction, comprising a tape base layer, an adhesive layer, and a separation layer. The adhesive layer is disposed on one side of the tape base layer in the thickness direction and includes a predetermined adhesive. The separation layer is disposed on the other side of the tape base layer in the thickness direction and includes a silicon separating agent, an olefin resin separating agent, or an acrylic resin separating agent having a long-chain alkyl group.

First claim

What is claimed is:

1. An adhesive tape-comprising:
a tape base layer having a first surface and a second surface;
an adhesive layer disposed in direct contact with said first surface of said tape base layer and including a predetermined adhesive; and
a separation layer disposed in direct contact with said second surface of said tape base layer and including an olefin resin separating agent,
a solubility parameter value of said olefin resin separating agent constituting said separation layer being greater than or equal to 7 (cal/cm 3 ) 1/2 and less than or equal to 9 (cal/cm 3 ) 1/2 , and
a solubility parameter value of said predetermined adhesive constituting said adhesive layer being greater than 9 (cal/cm 3 ) 1/2 and less than or equal to 14 (cal/cm 3 ) 1/2 , wherein
the adhesive tape further comprises in cross section:
a tape main body including said tape base layer, said adhesive layer, and separation layer; and
transferred layers formed on said tape main body by transfer from an ink ribbon;
said transferred layers including:
a first layer having a solubility parameter value greater than or equal to 7 (cal/cm 3 ) 1/2 and less than or equal to 9 (cal/cm 3 ) 1/2 ; and
a second layer having a solubility parameter value greater than or equal to 7 (cal/cm 3 ) 1/2 and less than equal to 9 (cal/cm 3 ) 1/2 .

2. The adhesive tape according to claim 1 , wherein:
said predetermined adhesive constituting said adhesive layer is an acrylic adhesive.

3. The adhesive tape according to claim 1 , wherein:
said adhesive tape is wound into an adhesive tape roll around a predetermined axis,
said adhesive tape comprising:
a tape base layer having a first surface and a second surface;
an adhesive layer disposed in direct contact with said first surface of said tape base layer and including a predetermined adhesive; and
a separation layer disposed in direct contact with said second surface of said tape base layer and including an olefin resin separating agent,
a solubility parameter value of said olefin resin separating agent constituting said separation layer is greater than or equal to 7 (cal/cm 3 ) 1/2 and less than or equal to 9 (cal/cm 3 ) 1/2 ,
a solubility parameter value of said predetermined adhesive constituting said adhesive layer is greater than 9 (cal/cm 3 ) 1/2 and less than or equal to 14 (cal/cm 3 ) 1/2 , and
said separation layer comes into contact with said adhesive layer.

4. The adhesive tape according to claim 1 , wherein:
said olefin resin separating agent of said separation layer is a crystalline olefin resin separating agent.

5. The adhesive tape according to claim 1 , wherein:
said transferred layers further comprise an ink layer disposed between said first layer and said second layer, and having a solubility parameter value greater than 9 (cal/cm 3 ) 1/2 and less than or equal to 11 (cal/cm 3 ) 1/2 , and comprised of a pigment,
said first layer is an underlayer that is melted by heat reception and separated from a ribbon base layer of said ink ribbon and
said second layer is a top layer stuck to said separation layer.

6. The adhesive tape according to claim 1 , wherein:
said transferred layers further comprise an ink layer disposed between said first layer and said second layer, and having a solubility parameter value greater than or equal to 7 (cal/cm 3 ) 1/2 and less than or equal to 9 (cal/cm 3 ) 1/2 , and comprised of a pigment,
said first layer is an underlayer that is melted by heat reception and separated from a ribbon base layer of said ink ribbon, and
said second layer is a top layer stuck to said separation layer.

7. The adhesive tape according to claim 1 , wherein:
said first layer is an underlayer that is melted by heat reception and separated from a ribbon base layer of said ink ribbon, and
said second layer is an ink layer comprised of a pigment and stuck to said separation layer.

8. The adhesive tape according to claim 1 , wherein:
said first layer is a layer that is melted by heat reception and separated from a ribbon base layer of said ink ribbon, and
said second layer is a top layer stuck to said separation layer.
