Further, a coating layer may be provided on the surface of the printing layer.

In this roll type tack label, a plurality of labels are arranged on the same release sheet in a direction perpendicular to the circumferential direction of the roll. A plurality of labels can be simultaneously attached in one process without any problem in sticking properties and sticking operability.

Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 is a plan view showing an example of a roll-type tack label of the present invention, FIG. 2 is an enlarged cross-sectional view taken along line XX, and FIG. 3 shows an example of a plastic product to which the tack label of the present invention has been applied. It is a front view.

This roll-type tack label 1 is composed of three labels A, B, and C that differ in appearance such as shape, size, color tone, and design, are arranged in a column in a direction perpendicular to the circumferential direction of the roll. Then, on the entire back surface side of the label base material 2, an aluminum vapor-deposited layer 3 for improving the design property, an adhesive layer 4 for adhering to the surface of the plastic product, and further when adhering to the surface of the plastic product. The label is easily peeled off, and there is no problem in sticking property and sticking operability, and a release sheet 5 for sticking to the surface of the plastic product is provided in this order.

Layers A covering layer 9 for covering are provided in this order. In such a case, it is preferable that the label substrate 2 and the coating layer 9 have high transparency.

In the roll-type tack label 1, the label A has a part of the solid printing layer 6 that is partially removed, and the part where the solid printed layer 6 is missing is because the aluminum vapor deposition layer 3 is visible through the label base material 2 and the coating layer 8. The label B has a metallic glossiness, and the gradation printing layer 7 allows the aluminum deposition layer 3 to pass through the label base material 2 and the coating layer 8 so that the gradation portion of the gradation printing layer 7 can be seen through.
The label C is provided with a solid print layer 6 and a print layer 8 for displaying a product name, a description of contents, and the like.
Thereby, it can play a role of providing information at the time of use to consumers and promoting sales at the time of sale.

When the roll-type tack label 1 is attached to the surface of a plastic product 10 as shown in FIG. 3, three labels having different shapes, sizes, colors, designs and the like are arranged in the circumferential direction of the roll. Since the three labels are arranged in a column in the vertical direction with respect to the conventional automatic labeling machine, these three labels can be efficiently stuck in one step without any problem in the sticking property and the sticking operability at the same time. .

As the label base material used for the tack label in the present invention, there are paper and plastic film. Examples of the paper substrate include high-quality paper, art paper, and cast-coated paper, and examples of processed paper include foil paper, impregnated paper, and colored paper. For plastic films, polypropylene, polyester, vinyl chloride films and synthetic paper,
There are foam films and the like. Further, there is a transparent film such as a polypropylene or polyester film in which aluminum is vapor-deposited on the adhesive side.

The label substrate to be used is selected depending on the required properties such as appearance such as color, texture and design, heat resistance, weather resistance and water resistance. The thickness of the label base material 2 has an adverse effect on handleability, workability, and the like when manufacturing the roll-type tack label 1 and on the sticking property and sticking operability when sticking the roll-type tack label 1 on a plastic product. Although it can be selected within a range that is not difficult, it is generally preferable to be 20 to 200 μm. The surface of the label substrate 2 on the printing layer side may be subjected to a conventional surface treatment such as a corona treatment, a plasma treatment, a frame treatment, and an acid treatment. By performing such treatment, printability and print adhesion can be improved.

The printing layers 6 to 8 can be formed by a conventional printing method such as screen printing, letterpress rotary printing, gravure printing, flexographic printing, offset printing, digital printing, and the like. Conventional printing inks such as a mold, an evaporative drying type, an oxidative polymerization type, and a penetration drying type can be used.

The material constituting the coating layer 9 is not particularly limited as long as it can protect the printing layer and is transparent, and includes, for example, polyolefin resins such as polyethylene and polypropylene, polystyrene and styrene as comonomer. Polystyrene resins such as styrene copolymers, and resins such as polyvinyl chloride, polyvinylidene chloride, and polyester can be used, and the coating layer 9 can be formed by coating these resins or film laminating. Among these resins, it is particularly preferable to use a polyolefin-based resin. For example, the coating layer 9 can be formed by laminating a stretched polypropylene film on the surface of the printing layer.

The thickness of the coating layer 9 depends on the handleability and workability when manufacturing the roll-type tack label 1 and the sticking property and sticking operability when sticking the roll-type tack label 1 on a plastic product. It can be selected appropriately as long as it does not hinder,
10 to 50 μm is preferred. The coating layer 9 is formed by, for example, a conventional laminating process such as adhesive lamination, dry lamination, or extrusion lamination, or a coating process. In the present invention, it is not always necessary to provide the coating layer 9.

The pressure-sensitive adhesive constituting the pressure-sensitive adhesive layer 4 is not particularly limited. However, the pressure-sensitive adhesive and the holding power are such that they do not spontaneously exfoliate after being adhered to a plastic product until the distribution process, sales, use and consumption. Are preferred. As the pressure-sensitive adhesive, a pressure-sensitive adhesive of an acrylic type, a rubber type, a silicone type or the like is used. The acrylic type includes an emulsion type and a solvent type, and the rubber type includes an emulsion type (latex type), a solvent type and a hot melt type. Examples of the acrylic pressure-sensitive adhesive include, for example, an alkyl acrylate such as ethyl acrylate, butyl acrylate, and 2-ethylhexyl acrylate, and an alkyl methacrylate such as butyl methacrylate and 2-ethylhexyl methacrylate as a base polymer. As the monomer component, a comonomer component such as methyl acrylate, methyl methacrylate, and vinyl acetate, and a carboxyl group-containing monomer such as acrylic acid, methacrylic acid, and maleic acid, and a hydroxyl group-containing monomer such as 2-hydroxyethyl (meth) acrylate A pressure-sensitive adhesive or the like using a copolymer mainly composed of components is used. The thickness of the pressure-sensitive adhesive layer 4 is, for example, 3 to 100 μm.
m, preferably about 5 to 40 μm.

The pressure-sensitive adhesive layer 4 is formed by coating a pressure-sensitive adhesive composition (emulsion, solution, etc.) containing a pressure-sensitive adhesive on the label substrate 2 using a conventional coating means such as a roll coater, a bar coater, a knife coater, or a spray. It can be formed by processing. Depending on the purpose or application, the non-adhesive masking layer that partially covers the surface of the pressure-sensitive adhesive layer 4 on the surface of the pressure-sensitive adhesive layer 4 or, in particular, when the plastic product has transparency, can be seen from the back side of the label substrate. Printing may be partially provided.

When the roll type tack label 1 is attached to the plastic product 10, it is preferable to attach the release sheet while peeling the release sheet from the label.

As the release sheet 5, a sheet or a film processed by silicone is used. There are two types of paper: semi-glassine type and craft type. The semi-glassine type has the strength of paper and is excellent in running property of a labeling machine. The type obtained by laminating kraft paper with polyethylene is used for those requiring high smoothness and low releasability, and has better dimensional stability than the glassine type. The film includes polyester, polypropylene, polyethylene and the like, and is excellent in transparency, strength, smoothness, and flatness.
