Abstract

A coreless thermal transfer recording web roll 10 is formed by rolling a thermal transfer recording web 10a in a roll. An inner end part 11 of the thermal transfer recording web 10a of the thermal transfer recording web roll 10 has a tab 11a formed at a substantially middle of the inner end part 11, and sticking parts 11b formed on the opposite sides of the tab 11a, respectively. Pseudoadhesive double-coated tapes 14 are attached to the sticking parts 11b, respectively. The pseudoadhesive double-coated tapes become tack-free after the sticking parts 11b have been separated from the innermost layer of the thermal transfer recording web 10a of the thermal transfer recording web roll 10.

Claims

1. A thermal transfer recording web roll for use on a printer, formed by winding a thermal transfer recording web having a base web, and a recording layer formed on one of the surfaces of the base web;

wherein

the thermal transfer recording web is wound in a substantially cylindrical shape,

a sticking part sticking to an innermost layer of the thermal transfer recording web is formed in an inner end part of the thermal transfer recording web, and

the outer surface of the inner end part of the thermal transfer recording web is held by the inner surface of the innermost layer of the thermal transfer recording web through the sticking part, wherein the inner end part of the thermal transfer recording web is provided with a tab for winding.

2. The thermal transfer recording web roll for a printer according to claim 1, wherein

the sticking part becomes tack-free after the outer surface of the inner end part of the thermal transfer recording web is separated from the inner surface, of the innermost layer of the thermal transfer recording web.

3. The thermal transfer recording web roll for a printer according to claim 1, wherein

the sticking part has a pseudoadhesive property that enables the sticking part to be separated from the innermost layer of the thermal transfer recording web by a peeling force not higher than a peeling force corresponding to a take-up torque exerted by the printer.

4. The thermal transfer recording web roll for use on a printer according to claim 3, wherein

the sticking part includes a pseudoadhesive a double-coated tape.

5. The thermal transfer recording web roll for use on a printer according to claim 1, wherein

the inner end part of the thermal transfer recording web has the tab formed in a middle part thereof with respect to the width, and a pair of sticking parts respectively on the Opposite sides of the tab.

6. The thermal transfer recording web roll for use on a printer according to claim 5, wherein

the tab and the sticking parts, are demarcated by slits, respectively.

7. The thermal transfer recording web roll for use on a printer according to claim 1, wherein

the tab projects in a winding direction of the thermal transfer recording web relative to the sticking part.

8. The thermal transfer recording web roll for use on a printer according to claim 7, wherein

the tab has a rectangular projection projecting from a middle part of the inner end of the thermal transfer recording web.

9. The thermal transfer recording web roll for use on a printer according to claim 7, wherein

the tab has a triangular projection projecting from a middle part of the inner end of the thermal transfer recording web.

10. The thermal transfer recording web roll for use on a printer according to claim 1, wherein

an adhesive layer is formed on the other surface of the base web, and a release tape is applied to the adhesive layer.

11. The thermal transfer recording web roll for use on a printer according to claim 1, wherein

a noncontact IC tag is attached to a part of the thermal transfer recording web near the inner end part of the thermal transfer recording web.

12. The thermal transfer recording web roll for use on a printer according to claim 1, wherein

adhesive strength of the sticking part between the innermost layer of the thermal transfer recording web and the inner end part of the thermal transfer recording web is higher than a peeling force corresponding to a take-up torque exerted by the printer.
