Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to improvements in marking materials such as emblems, labels, stickers, and stripe tapes having weed portions (described later).

[Conventional technology]

The production procedure and usage method of a conventional marking material having a weed portion (described later) will be explained using FIGS. 5 to 8. Figure 5 shows adhesive layer 2 and base material 1 on release material 3.
, shows a marking material in which printing layers 6 are laminated in this order. The printing layer 6, the base material 1, and the adhesive layer 2 of the marking material
A cut (hereinafter referred to as a "kiss cut") 4 is made in the desired shape using a knife, a back die, or the like. Next, the printed layer 6, the base material 1, and the adhesive layer 2 in the unnecessary part (The part where the base material etc. were removed by the weeding operation) can be created. A protective paper (masking tape) 5 having an adhesive layer with lower adhesive strength than the adhesive layer 2 of the marking material is laminated on top of the marking material, and a knife, temporary mold, scissors, etc. are used to shape it into the desired shape. When the material from the protective paper 5 to the release material 3 is cut (hereinafter referred to as die-cutting) using the die cutting method, a marking material having a weed portion as shown in FIG. 7 is completed. Next, the release material 3 of the marking material was removed, the marking material was affixed to the adherend 8 with a squeegee, etc., and the protective paper 5 was further removed, and the surface of the adherend 80 was exposed at the weed portion shown in FIG. Marking becomes possible.

[Problem that the invention seeks to solve]

The above-mentioned weeding work is generally performed on areas divided by complex-shaped kiss cuts, so mechanical processing is difficult and has to be performed manually. Particularly in specifications where the marking part has a fine shape, weeding work must be performed with great care, resulting in poor workability and a high incidence of defects.

An object of the present invention is to provide a marking material that does not require weeding work and is capable of displaying the same markings as conventional marking materials having weeded portions.

Means for Solving Problem C] The present invention laminates an adhesive layer and a release material in this order on one side of a base material, and provides a printed layer on the other side of the base material either as is or on the other side, and then The present invention relates to a marking material in which protective paper is laminated, a marking part and an unnecessary part are separated by a kiss cut, and the adhesive strength of each layer is in the relationship D<A<B<C. Here, A is the adhesive strength between the protective paper and the base material or the printed layer in the marking area of the marking material divided by kiss cuts, B is the adhesive strength between the adhesive layer of the marking material and the marking material to which it is adhered, and C D means the adhesive strength between the protective paper and the base material or the printed layer in the unnecessary parts of the marking material divided by kiss cuts, and D means the adhesive strength between the release material of the marking material and the adhesive layer.

A first embodiment of the present invention will be described using FIG. 1. In FIG. 1, an adhesive layer 2 and a peeling layer 113 are laminated in this order on one side of a base material 1, and a printing layer 6 is laminated on the other side of the base material 1 as desired.
will be established. Furthermore, an adhesive layer 2 is formed on the base material 1 or the printed layer θ.
Protective paper 5 having an adhesive layer with adhesive strength superior to that of
indicates the laminated marking material. The marking material is provided with a kiss cut 4 that separates the marking part from the unnecessary part, and a slip coat layer 7 is provided between the base material 1 or printed layer 6 of the marking part and the protective paper 5. It is being Since the strip coat layer 7 is made of a material that has some releasability, the adhesive strength between the protective paper 5 in the marking part of the marking material and the base material 1 or the printed layer 6 via the strip layer 7 is as follows.
The adhesive strength is lower than that between the adhesive layer 2 of the marking material and the adherend 8. Further, the adhesive strength between the adhesive layer 2 and the release material 3 is configured to be inferior to the adhesive strength of any of the layers. Therefore, when the release material 3 of the above-mentioned marking material is removed and pasted on the adherend 8, and the protective paper 5 is peeled off,
Since the strip coat layer 7 and the marking material in unnecessary areas are in close contact with the protective paper 5 and removed, as shown in FIG.
Marking can be done with the surface exposed.

Next, a second embodiment of the present invention will be described using FIG. 3. In FIG. 3, similarly to the first embodiment, the base material 1,
An adhesive layer 2, a release material 3, a printing layer 6, a protective paper 5, and a kiss cut 4 are provided. The difference from the first embodiment is that the adhesive strength of the adhesive of the protective paper 5 is inferior to that of the adhesive layer 2 of the marking material. Further, a contact layer 9 is provided between the protective paper 5 and the base material 1 or the printed layer 6 in the unnecessary portion of the marking material divided by the kiss cut. The contact layer 9 has the ability to increase the adhesive strength between the protective paper 5 and the base material 1 or the printed layer 6, and has the ability to increase the adhesive strength between the protective paper 5 and the base material 1 or the printed layer 6 in areas where marking material is not required. The adhesive strength is configured to be superior to the adhesive strength between the adhesive layer 2 and the adherend 8. Further, the adhesive strength between the adhesive layer 2 and the release material 3 is configured to be inferior to the adhesive strength of any of the layers. Therefore, when the release material 3 of the above-mentioned marking material is removed and adhered to the adherend 8, and the protective paper 5 is peeled off, the contact layer 9 and unnecessary marking material are adhered to the protective paper 5 and can be removed. As shown in FIG. 4, marking can be performed in unnecessary areas so that the surface of the adherend 8 is exposed.

Next, the procedure for creating the marking material of the present invention will be explained. Synthetic resin films such as vinyl chloride, acrylic, and polyester, and metal foils such as aluminum, tin, gold, and silver are used as base materials, and rubber, acrylic, urethane, silicone, polyester, epoxy, etc. A marking material is used in which a general-purpose adhesive layer is laminated with a general-purpose release material such as a releasable silicone-treated paper, and therefore the adhesive strength between the adhesive layer and the release material is the weakest. On top of this, print layers of various shapes and colors are printed on the base material as desired using vinyl chloride ink, acrylic ink, etc., by printing methods such as screen, gravure, offset, etc., or coating methods such as roll coating, knife coating, etc. Provided for. Next, in the case of the first embodiment, a strip coat layer is formed on the marking part of the marking material by screen printing, offset printing, etc., and further processing of kiss cutting, lamination of protective paper, and die cutting is performed. marking material is created.

In the case of the second embodiment, after the printing layer is provided, kiss-cutting is performed, and then a contact layer is formed on unnecessary parts of the marking material by screen printing, offset printing, etc., and then protective paper is laminated and die-cutting is performed. The marking material of the present invention can be created by performing the following processing. In addition, when using a heat-sensitive adhesive as a contact layer, it is also possible to perform a kiss cut process after forming a contact layer. As the strip coat layer used in the present invention, any general-purpose marking material that is printable and forms a layer with low adhesive strength with the printing layer can be used. Specifically, vinyl acetate emulsion ( Movinyl DC manufactured by Hoechst Synthesis ■ alone or vinyl acetate emulsion and PVA (
