Description

DETAILED DESCRIPTION OF THE INVENTION [0001] TECHNICAL FIELD The present invention relates to a thermal transfer ribbon.
More specifically, a release layer is placed under the thermal transfer ink layer.
The present invention relates to a partially provided thermal transfer ribbon. [0002] 2. Description of the Related Art Conventionally, various thermal transfer methods are known.
However, this method forms a colored transfer layer on a substrate,
From the side, using a thermal head, etc.,
By heating an image such as a pattern to the image shape,
This is for thermally transferring the transfer layer to the surface of the material to be transferred. this
The thermal transfer method uses sublimation transfer depending on the configuration of the colored transfer layer.
It can be broadly classified into two types: a printing type and a hot-melt transfer type. Sublimation transfer type
Dyes that sublimate or migrate due to heat
The colored transfer layer is supported on the substrate by
The dye in the colored transfer layer is transferred to the surface of the
Heat transfer to However, on the surface of the material to be transferred,
It is provided with a receiving layer that is easy to dye. So
On the other hand, the hot-melt transfer type easily
Softening and melting to form a transferable colored transfer layer
Transfer the colored transfer layer to the surface of the material to be transferred.
Things. [0003] Both types, mono-color and multi-color color
-Images can be formed, and in the case of multi-color images,
For example, yellow, magenta, cyan and more
Available in three or four colors of black thermal transfer ribbon
Thermal transfer of each color to the surface of the same
An image is formed. For such a thermal transfer ribbon
In addition, three or four colors are face-sequential on the same ribbon,
As shown in Fig. 1, what is repeatedly painted
It is used. Also, yellow, magenta, cyan
Not only the black transfer layer, but also the receiving layer,
Protective layer is also applied on the same ribbon by surface
Transfer ribbons have also been used. This receiving layer
Is a layer for facilitating dyeing.
It is formed by thermal transfer on the surface of the transfer material. Ma
In addition, the protective layer is formed after the colored transfer layer is thermally transferred to the material to be transferred.
Formed on the thermally transferred image by thermal transfer.
It is. Now, the end of such a thermal transfer ribbon is bent.
When mounting on a tape, use an adhesive tape as shown in Figure 2.

Problem. The present invention has been made in view of such circumstances.
To secure the end of the thermal transfer ribbon to the bobbin
In some cases, blocking occurs due to the adhesive sticking out of the adhesive layer.
It does not fray and the thermal transfer ribbon peels off the bobbin
At this time, the peeled pieces scatter inside the printer and
Contamination inside the printer, malfunction or damage to the printer.
