Field of the Invention The present invention relates to a label manufacturing method, a label laminating material, and a label capable of freely selecting and changing adhesiveness, peelability, texture, and background pattern in response to diversifying products. is there.

[0002]

2. Description of the Related Art In recent years, for example, various electronic products or other products use labels for displaying product types, characteristics, handling methods, precautions, and other information.

[0003] There are many types of these products, and the products are frequently changed. Therefore, recording is performed on a label by a thermal head.

As an example of a label printed by such a thermal head, Japanese Patent Publication No. Hei 7-37185 discloses a "thermal recording label".

[0005] This "thermosensitive recording label" is such that, in a handling environment of a product to which the label is attached, chemicals, oil, water, etc. penetrate into the thermosensitive coloring layer, so that the printed portion is discolored or the uncolored background portion is removed. The purpose of the present invention is to prevent the occurrence of fogging or that the printed portion becomes unreadable due to scratches repeatedly rubbed by a scanner or the like during the distribution process. A layer, an intermediate layer, an adhesive layer and a release paper, wherein the intermediate layer is mainly composed of a water-soluble polymer and a white pigment. "

[0006]

However, recently, there has been a demand for diversification of products and shortening of delivery time of products. In order to diversify this product, there is a demand to display a common picture, character, ruled line, etc. on the label, and to use aluminum evaporated film, PET, synthetic paper, etc. for the label base material, Therefore, it is necessary to select an adhesive having various properties such as strong adhesion, weak adhesion, and removability.

Further, in order to shorten the delivery time of a product, a variety of labels must be prepared in order to use a label corresponding to a base material or an adhesive in advance.

On the other hand, depending on the product to which the label is attached,
After affixing a label to a product, the serial number or lot number of the product may be entered.If the label is affixed to the product beforehand, the thermal head Is difficult to print.

Generally, a thermal label which is printed by a thermal head is limited to a relatively low range due to its printing characteristics. When used in a high-temperature environment, the thermal label may develop color, and there is a problem with heat resistance. There is.

The present invention has been made in view of such various problems. In response to the diversification of products, common patterns (pictures, ruled lines, images, characters, textures of ground patterns, etc.) have been developed.
It is easy to select and change the material of the label, and also to select and change the base material of the label. It is also possible to print on the label affixed to the product. It is still another object of the present invention to produce a laser marker label capable of performing precise printing without blurring in printing.
