吸収法によるかしておこなわれていた。2. Description of the Related Art A heat-sensitive adhesive is provided as an adhesive applied to the back surface of a label. This heat-sensitive adhesive (also called delayed tack adhesive) is disclosed in Japanese Patent Publication No. 62-
As disclosed in Japanese Patent No. 21835 and Japanese Patent Application Laid-Open No. 1-96274, it contains a crystalline plasticizer and a tackifier as main components and does not show tackiness at room temperature, but is crystalline plastic. By heating above the melting temperature of the agent, it becomes activated and appears sticky, and this stickiness has the property of lasting for a long time. It is not necessary to use a pattern paper or the like, and the label can be easily attached to a container or the like by making the label sticky by only heating the label. A heat-sensitive adhesive label can be prepared by applying the heat-sensitive adhesive to the back surface of the label, either entirely or partially. The color of the heat-sensitive adhesive is generally white or pale yellowish white, which is often the same as the color of the background of the label, and it is difficult to visually distinguish the coating amount. For this reason, control of the coating amount of the heat-sensitive adhesive is carried out by the absolute dry weight method or by the IR.
It was done by the absorption method.

を提供することを目的とするものである。However, the absolute dry weight method requires a complicated work of coating the heat-sensitive adhesive, then drying and measuring the weight, and as a method of controlling the coating amount on site, it is necessary. However, the IR absorption method has a problem that an expensive measuring device is required. Moreover, these methods also have a problem that it is difficult to determine whether or not the heat-sensitive adhesive has been applied uniformly. further,
As described above, the heat-sensitive adhesive is often white or pale yellowish white and has the same color as the background of the label, and moreover, the touch is almost the same as that of the paper of the label. When making a heat-sensitive adhesive label by partially applying to the back surface of the label, it is difficult to distinguish the boundary between the part to which the heat-sensitive adhesive is applied and the part to which the heat-sensitive adhesive is not applied, and the part to which the heat-sensitive adhesive is applied is There is also a problem that it is difficult to print on a label corresponding to the uncoated portion or to make a perforation at this boundary. The present invention has been made in view of the above points, and it is possible to visually distinguish the coating amount of the heat-sensitive adhesive and to measure the coating amount using an inexpensive device such as a color densitometer. Becomes
Another object of the present invention is to provide a heat-sensitive adhesive label capable of easily discriminating unevenness of application of the heat-sensitive adhesive and further easily distinguishing a coated portion and a non-coated portion of the heat-sensitive adhesive on the label. It is what

なくすることができるものである。The heat-sensitive adhesive label according to the present invention is formed by mixing a heat-sensitive adhesive with a coloring agent for coloring, and applying the colored heat-sensitive adhesive to the back surface of the label. It is characterized by. Hereinafter, the present invention will be described in detail. The heat-sensitive adhesive is mainly composed of a crystalline plasticizer such as dicyclohexyl phthalate (DCHP) and a tackifier such as styrene-based resin, styrene-butadiene-based resin, acrylic resin, rosin-based resin, and a lubricant or stabilizer. Such as those prepared by adding, etc.
The materials provided in Japanese Patent Laid-Open No. 5-96274 and Japanese Patent Laid-Open No. 1-96274 can be used. In the present invention, the heat-sensitive adhesive is colored and used by blending and mixing a colorant with the heat-sensitive adhesive. As the colorant, a pigment or dye having good compatibility with the heat-sensitive adhesive can be used, and its color is arbitrary, but a color different from the background color of the label to which the heat-sensitive adhesive is applied is different. It is the one that is selected. The amount of the colorant compounded is not particularly limited, but is 0.5 with respect to the total solid content of the heat-sensitive adhesive.
The range of about 2% by weight is preferable. The heat-sensitive adhesive label can be prepared by applying the colored heat-sensitive adhesive to the back surface of the label. The application of the heat-sensitive adhesive can be carried out by any application method or printing method, and in addition to creating the heat-sensitive adhesive label by applying the heat-sensitive adhesive to the entire back surface of the label, It is also possible to partially apply a heat-sensitive adhesive to the back surface, attach a part to a container or the like, and create a heat-sensitive adhesive label in which the other part can be separated. The partial application of the heat-sensitive adhesive to the back surface of the label can be performed by printing the heat-sensitive adhesive on a part of the back surface of the label by a printing method such as gravure printing or screen printing. In the heat-sensitive adhesive label produced in this manner, since the heat-sensitive adhesive is colored, the color becomes darker as the amount of the heat-sensitive adhesive applied to the label increases, and the color shade may change. The coating amount can be visually controlled. For example, by creating a standard color sample showing the relationship between the coating amount and the color density and comparing the color density of the heat sensitive adhesive applied to the label with the color sample,
The amount of the heat-sensitive adhesive applied to the label can be easily confirmed. In this way, since the coating amount of the heat-sensitive adhesive can be immediately known by visual inspection, it is possible to easily control the coating amount of the heat-sensitive adhesive at the site where the heat-sensitive adhesive is applied to the label. . Also, if the heat-sensitive adhesive is applied uniformly to the label, the color density on the back surface of the label is uniform, but if the application becomes uneven and the application amount partially varies, the application amount The color density is high in the areas with a large amount and the color density is low in the areas with a small coating amount. Therefore, it is possible to easily visually judge whether the heat-sensitive adhesive is applied uniformly or whether the application is uneven and uneven, and it is possible to easily control the uniformity of the application of the heat-sensitive adhesive. It is possible. In addition to visually controlling the amount of the heat-sensitive adhesive to be applied and evenly controlling the application as described above, an inexpensive device such as a color densitometer may be used. Since the color densitometer can directly detect the coating amount of the heat-sensitive adhesive by a numerical value, delicate management becomes possible. Furthermore, when a heat-sensitive adhesive is partially coated on the back surface of the label to form a heat-sensitive adhesive label, the heat-sensitive adhesive is colored and therefore the part to which the heat-sensitive adhesive is applied is not applied. Since the part and the part are color-coded, the boundary between the two parts can be easily confirmed visually. Therefore, print on the label corresponding to the part where the heat-sensitive adhesive is applied and the part where it is not applied,
Perforations can be easily formed on this boundary with high accuracy. In addition, when the partial application of the heat-sensitive adhesive to the label is performed several times, it is possible to accurately register the overlapping position of the application. In addition, even if the label paper is yellowed, it can be made inconspicuous by coloring the heat-sensitive adhesive.

とができた。EXAMPLES The present invention will be specifically described below with reference to examples. (Example 1) Water-based ink ("GF Indigo" manufactured by Dainippon Ink and Chemicals, Inc.) was added to a heat-sensitive adhesive ("DLA-1" manufactured by Dainippon Ink and Chemicals, Inc.) in a solid content of 2% by weight.
It was colored indigo by adding and mixing. Then, apply this colored heat-sensitive adhesive to the entire back surface of white single-sided art paper (Kanzaki Paper Co., Ltd. "Kinto single-sided art").
A heat-sensitive adhesive label paper was obtained by applying an application amount of 5 g / m 2 (solid content). The heat-sensitive adhesive label paper prepared in this way can control the coating amount by visually inspecting the color density of the heat-sensitive adhesive,
It was also possible to manage uneven coating. Further, by using the FAG densitometer, it was possible to accurately control the coating amount and the coating unevenness. In addition, the color of the front and back of the label depends on the coloring of the heat-sensitive adhesive,
The distinction between the front and back when printing labels became clear. (Example 2) To the same heat-sensitive adhesive as in Example 1, 2% by weight in terms of solid content of water-based ink ("GF Red" manufactured by Dainippon Ink and Chemicals, Inc.) was added to give a red color. Then, the colored heat-sensitive adhesive 2 is applied to the back surface of the same paper as in Example 1.
A heat-sensitive adhesive label paper was obtained by partially screen-printing and applying with an application amount of 0 g / m 2 (solid content). With this product, the boundary between the part where the heat-sensitive adhesive is applied and the part where it is not applied can be clearly seen by color coding, and the label is printed corresponding to the part where the heat-sensitive adhesive is applied and the part where it is not applied. It was also easy to make a perforation at this boundary. (Example 3) The same heat-sensitive adhesive as in Example 1 was added with a water-based ink ("GF Yellow" manufactured by Dainippon Ink and Chemicals, Inc.) in an amount of 2% by weight in terms of solid content, and colored yellow. Then, the colored heat-sensitive adhesive was applied on the back surface of the same paper as in Example 1
A heat-sensitive adhesive label paper was obtained by performing partial application three times with a gravure printing machine at an application amount of g / m 2 (solid content). With this, it was possible to easily register the registration of the overlapping of the application of the heat-sensitive adhesive three times.
