DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for antibacterial treatment of printed matter such as a notebook cover.

[0002]

2. Description of the Related Art Bacteria such as Escherichia coli tend to adhere to printed matter such as the cover of a notebook, which is not preferable in terms of hygiene. Therefore, in order to keep them clean, it is desired to perform antibacterial treatment. By the way, when applying antibacterial treatment to paper products,
It is common practice to infiltrate the paper with an antimicrobial agent. However, in the case of printed matter, since the printing ink covers the surface of the paper, there is a problem that the effectiveness of the antibacterial agent is weak.

[0003]

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a novel antibacterial treatment method for a printed matter such as a notebook cover which can increase the antibacterial effect of the printed matter such as a notebook cover and can be extremely hygienic.

[0004]

In order to achieve the above object, a method for antibacterial treatment of a printed matter such as a notebook cover according to the present invention comprises printing an arbitrary design on a surface of a paper 1 using a printing ink. And then applying a powdered antibacterial agent dissolved in water thereon.

[0005] In the present specification, "a powdery antibacterial agent dissolved in water" refers to a powdered antibacterial agent dissolved in water, an antibacterial agent which is not dissolved but is dispersed in water. Agents.

[0006]

Since an antibacterial agent coating layer dissolved in water is formed on the printing ink layer, the antibacterial agent easily acts on bacteria adhering to the surface.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS As an embodiment of the present invention, an antibacterial treatment method for a notebook cover will be described below. First, an arbitrary design is first printed on paper using a printing ink. As the printing ink, an ink having the following composition can be used. Pigment 15 to 25 (%) Synthetic resin 25 to 30 Dry oil 20 to 25 Petroleum solvent 15 to 20 Film strengthening agent 1 to 3 Offset inhibitor 0.5 to 2.5 Dryer and other solvents 1 to 3

Next, a powdery antibacterial agent dissolved in water is applied on the printing ink layer. Offset printing is preferred as a method of applying. Here, as the antibacterial agent, a metal (e.g., silver, etc.) or an organic (e.g., benzalkonium, cetylpyridinium, etc.) having antibacterial performance was intercalated (ion-exchanged) with a poorly soluble phosphate. Things can be used.

The above antibacterial agent is used in an amount of about 2.
It is preferable to add 5%.

FIG. 1 shows a partial cross section of a cover of a notebook which has been subjected to antibacterial treatment according to the above embodiment of the present invention. In the figure, reference numeral 1 denotes a notebook cover paper, reference numeral 2 denotes a printing ink layer formed on the paper 1, and reference numeral 3 denotes a water-dissolved antibacterial agent formed on the printing ink layer 2. It is an agent application layer. In the antibacterial agent application layer 3 dissolved in water, water evaporates by drying, so that only the antibacterial agent finally adheres to the printing ink layer 2.

[0011]

As described above, the antibacterial treatment method of the printed matter such as the cover of a notebook according to the present invention is as follows. By taking the step of further applying a powdered antibacterial agent, the antibacterial agent can easily act on bacteria adhering to the surface, so that the antibacterial effect of the printed matter such as the cover of the notebook increases and it becomes extremely sanitary. effective.
