Abstract

A transfer sheet includes a base sheet and a transfer body. The transfer body includes a liquid-soluble adhesive layer and a liquid-insoluble sheet main body layer laminated on the liquid-soluble adhesive layer. The sheet main body layer includes a sticking layer adjacently laminated on the adhesive layer and a design layer adjacently laminated on the sticking layer. The sticking layer includes a protruding portion protruding outward beyond an end edge of the design layer. The protruding portion is transparent.

First claim

What is claimed is:

1. A transfer sheet comprising:
a base sheet; and
a transfer body laminated on the base sheet,
the transfer body including:
a liquid-soluble adhesive layer laminated on the base sheet, and
a liquid-insoluble sheet main body layer laminated on the liquid-soluble adhesive layer,

the sheet main body layer including
a sticking layer adjacently laminated on the adhesive layer at an opposite side of the base sheet and having a function of sticking the sheet main body layer to a sticking target object and
a design layer adjacently laminated on the sticking layer at an opposite side of the adhesive layer,

the sticking layer including a protruding portion protruding outward beyond an end edge of the design layer, the protruding portion being transparent.

2. The transfer sheet according to claim 1 , wherein the protruding portion of the sticking layer has such a shape as to surround the end edge of the design layer along the end edge of the design layer.

3. The transfer sheet according to claim 1 , wherein the protruding portion of the sticking layer has a protruding width of 1 mm or more from the end edge of the design layer.

4. The transfer sheet according to claim 1 , wherein the entire sticking layer is transparent.

5. The transfer sheet according to claim 1 , wherein:
the sticking layer includes
a transparent sticking layer adjacently laminated on the adhesive layer and
a non-transparent sticking hiding layer laminated on the transparent sticking layer so as to be adjacent to a side where the design layer is provided; and

the sticking hiding layer is arranged at an inside of the end edge of the design layer.

6. The transfer sheet according to claim 1 , further comprising a clear layer that covers the entire design layer and contacts at least the protruding portion of the sticking layer.

7. The transfer sheet according to claim 1 , wherein:
a thickness of the transfer body is more than 10 μm and less than 100 μm; and
a thickness of the design layer is more than 1 μm and less than 50 μm.

8. The transfer sheet according to claim 1 , wherein the sticking layer includes a transparent portion sandwiched directly between the end edge of the design layer and the liquid-soluble adhesive layer.

9. The transfer sheet according to claim 1 , wherein the protruding portion of the sticking layer protrudes outward beyond a clear layer in a direction perpendicular to a laminating direction.

10. The transfer sheet according to claim 1 , wherein:
the sticking layer includes a sticking hiding layer and a transparent sticking layer having a shape surrounding a peripheral edge of the sticking hiding layer,
the sticking hiding layer is included in the design layer in a plan view, and
the transparent sticking layer includes the protruding portion.

11. The transfer sheet according to claim 1 , wherein:
the sticking layer includes a sticking hiding layer laminated on the adhesive layer and a transparent sticking layer laminated on the sticking hiding layer,
the transparent sticking layer protrudes outward beyond the sticking hiding layer in a direction perpendicular to a laminating direction and covers an end edge of the sticking hiding layer, and
the transparent sticking layer includes the protruding portion.
