2. Description of the Related Art An image receiving tape for a tape writer, a so-called lettering tape, has a layered structure in which a printable base material, an adhesive layer and a separator are sequentially laminated and is wound on a tape core. The base material is provided with an image-receiving layer on which characters and the like are thermally transferred from an ink ribbon by a thermal head, or a thermosensitive coloring layer that directly develops heat by a thermal head to enable printing. However, such a lettering tape is very troublesome to peel off the separator when the necessary portion is cut off after printing and the separator is peeled off and attached to the adherend.

In order to solve such a problem, a lettering tape has been proposed in which a part of a corner is half-cut from the base material side or the separator side, or a half-cut portion is formed from the separator side. For example, in the lettering tape disclosed in JP-A-6-135167, the separator is half-cut. With this tape, the separator can be easily peeled off by a method of mountain-folding (splitting) the separator side into two when the separator is peeled off after printing.

However, in such a lettering tape, when it is stored at a high temperature, the adhesive sticks out from the half-cut portion in a streak pattern, so that the adhesive adheres to the printing portion or the base material to deteriorate the printability. , Stain may adhere to the surface of the substrate. In addition, when the separator is half-cut, the processing blade may reach the pressure-sensitive adhesive layer or the base material to form streak-shaped convex portions in the printed portion, which may cause printing defects.

In order to solve such a problem, it is possible to slit the separator in advance and attach a plurality of separators to the pressure-sensitive adhesive layer, but it requires an advanced attaching technique and the number of steps is increased, so that the production is increased. High cost.

An object of the present invention is to provide a long label image receptor having good printability and capable of easily peeling off the separator when the lettering tape is attached to the adherend after printing.

The pressure-sensitive adhesive layer 3 includes a separator 4 temporarily attached to the pressure-sensitive adhesive layer 3. This label receiver original 1
First, after half-cutting 21 using the half-cutting round blade 12 from the end in the width direction at a constant interval, the slit-shaped round blade (not shown) is used to make a constant width in the longitudinal direction. Slit. In the production of the printing tape, printing is performed on the printing layer 5 on the tape surface using a thermal head (not shown), and the printing tape is cut to a required length.

It should be noted that, as shown in FIG. 3, the ear portion 22 (half cut portion) separated by the half cut 21 of the label image receptor and the printing tape is formed during the manufacturing process of the label image receptor.
Alternatively, it may be removed after the half-cut in FIG. 2 to obtain the long label image receptor or the printing tape from which the ears are removed.

Although the printing layer 5 is provided on the outer surface of the base material 2 in the specific examples shown in FIGS. 1 and 2, as an alternative method, the thermosensitive coloring provided on the adhesive layer side of the base material 2 is used. It may be a layer.

The base material used for the label receiver and the printing tape of the present invention is a transparent, white or color printed flexible base material, and paper or plastic film is preferably used, for example, polyethylene film. , Polyester film, polypropylene film, polyvinyl chloride film, polycarbonate film, nylon film, polystyrene film, ethylene-vinyl alcohol copolymer film and the like. The thickness of the base material is not particularly limited, but is 10 to 10 from the viewpoint of handleability when attached to an object and windability onto a tape core.
About 0 μm is preferable.

It is preferable to provide an appropriate printable layer on these substrates. As such a printing layer, a thermal transfer image-receiving layer to which an ink ribbon is thermally transferred by a thermal head, a thermosensitive coloring layer and a heat-resistant protective layer which develop color by heating, or the like are applied.

Examples of the material used for the pressure-sensitive adhesive layer formed on one surface of the base material include a copolymer of an alkyl acrylate ester having an alkyl group having 2 to 12 carbon atoms and the ester, natural rubber, Butyl rubber, polyisobutylene rubber, styrene-isobutylene-styrene block polymer, styrene-butadiene-styrene block polymer, or other simple rubbers, or a mixture of these with a tackifying resin such as petroleum-based resin, rosin, or xylene resin. To be The thickness of the pressure-sensitive adhesive layer is not particularly limited, but is usually about 5 to 30 μm from the viewpoint of handleability when attached to an object and windability on a tape core, and is 10 to 2 μm.
It is preferably 0 μm.

As the separator, for example, one having surface releasability such as polyethylene may be used,
The surface of a thin base material that does not have surface releasability such as paper or plastics other than polyethylene is treated with silicone resin,
You may use what was coat-processed by the low adhesive resin like a fluororesin. The thickness of the separator is usually about 40 to 120 μm, preferably 60 to 80 μm from the viewpoints of peeling workability, handling, and winding property on a tape core.

The half cut applied to the label receiver of the present invention is about 1 to 2 mm from the widthwise end of the label receiver.
It is preferable to apply to the part. When the half cut is applied to the position less than 1 to 2 mm from the end, it is difficult to peel the separator, while the half cut part (ear part) is 1 to
If the width is wider than 2 mm, the printing portion becomes narrow and it cannot be used for a general-purpose tape writer.

[0017]

According to the present invention, when the separator is peeled from the base material and the pressure-sensitive adhesive layer in the label image receptor after printing, the label image receptor is divided into two by a half cut provided at a width of 1 to 2 mm from the end of the label image receptor. Thus, the separator can be easily peeled off by bending. Further, by removing the half cut portion in the label image receptor manufacturing step, the remaining separator portion can be used as a knob portion, and the separator can be easily peeled off. Furthermore, since the substrate is half-cut, the printability of the substrate is not adversely affected, and the surface of the substrate does not become soiled even when stored at high temperature in a state of being wound around the tape core.
