FIG. 1 shows a schematic diagram of a desk calendar and an explanatory diagram of how to use it as an embodiment of the calendar information display medium in the present invention. Monthly information, date information, day of the week information, etc. are generally printed on the desk calendar.

In the desk calendar shown in FIG. 1, in the initial state, as shown in FIG. 1(a), the date information is visible in the color of the cover-up printed portion using cover-up ink. The color of the concealing ink is a color that indicates the user's weekdays (mainly days that are not holidays, etc.). The color is not limited to these colors as long as it is a color that hides the color ink described later and makes it difficult to see, in accordance with the design of .

FIG. 1(b) is an enlarged view of the first week portion of the calendar information in FIG. 1(a). By rubbing with a silicon rubber attached to a tool or the like, the concealed ink on the concealed printed portion on the surface is erased, and the color printed portion using the color ink at the bottom of the concealed printed portion becomes visible. The color of the color ink is the user's special day (hereinafter, the description is based on the assumption that it is a holiday, but depending on the user, it may be a day indicating that there are some plans, and the usage is not limited). For example, red, vermilion, blue, etc. are common in desk calendars, but in accordance with the design of the calendar information display team, it is a color that becomes difficult to see by overlaying concealing ink on top. I wish I had.

By erasing the concealing ink for arbitrary date information in this manner, the user displays the desk calendar so that only the dates on which the user is a holiday are displayed in colored ink, as shown in FIG. 1(d). It can be customized without spoiling the design.

In the embodiment of FIG. 1, it was explained that only the date information can be customized. may be customizable, and all calendar information may be customizable.

FIG. 2(a) shows an embodiment of a sectional view of the desktop calendar taken along line XX' of FIG. 1(b).

The desk calendar in this embodiment has a normal printed part printed with normal ink and a color printed part printed with color ink on the base material, and a cover printed part printed with cover ink on the color printed part. The printed part is laminated. Although the layers are clearly separated from the normal printed area and the color printed area, the layers are not necessarily clearly separated. , or mixed colors.

The material of the base material is paper, synthetic paper, plastic sheet, etc., which are generally used for calendars, notebooks, etc., and any material that does not hinder the decolorization or discoloration of the color printed part printed on it. There are no particular restrictions.

The normal printing unit constitutes a portion of the calendar information that does not need to be customized by the user. Printed with normal ink that does not change color or fade to the extent that humans can see it even when the following heat is applied. The normal print portion may be composed of a single color or multiple colors of two or more colors, and there is no problem even if the same color tone as the color ink is included. It is preferable to use an oil-based ink as the normal ink, or use an ink that is cured by UV or the like, and perform a curing treatment after printing. As a result, it is possible to reduce color mixture with a color printed portion to be printed later.

The color printing part constitutes a part of the calendar information that can be customized by the user, including at least the date information. Like the normal printing part, the color change is visible to humans even when heat is applied at 100°C or less. Or printed with non-erasable color ink. Colored inks can be of the same type as normal inks, and since the scheduler indicates the user's holidays, any color, such as red, vermilion, or blue, can be selected according to the design of the scheduler. It is possible, but it is necessary to create a color that is difficult for people to see by layering concealing ink on top. Also, the color printing section may be composed of not only a single color but also two or more colors. For the color ink, it is preferable to use an oil-based ink or an ink that is cured by UV or the like and perform a curing treatment after printing.

The color printed portion may be solidly printed, but the concealed printed portion may be formed by hatching as shown in FIG. 3(a) or halftone dots as shown in FIG. 3(b). When superimposed, it becomes more difficult to see, and it is possible to improve the design.

The normal printing department and the color printing department are general printing techniques such as offset printing method, screen printing method, gravure printing method, letterpress printing method, intaglio printing method, and flexographic printing method. However, the normal inks and color inks to be used have ink compositions suitable for the respective printing techniques. Therefore, by using the same kind of ink for the normal ink and the color ink, it is possible to print the normal print portion and the color print portion in one process.

The concealing printed portion is printed on the color printed portion in a shape similar to that of the printed portion using concealing ink that decolorizes or changes color under specific conditions. In the initial state, the concealing ink must be concealed to such an extent that it is difficult for people to visually recognize the colored ink. It can be.

The cover-up printing part, like the above-mentioned normal printing part and color printing part, is a general printing technique, such as offset printing method, screen printing method, gravure printing method, letterpress printing method, intaglio printing method, flexographic printing method, etc. Any printing technique may be used for printing, but the concealing ink to be used has an ink composition suitable for each printing technique.

As the color ink and the concealing ink, inks that cure under specific conditions, typically UV curable inks, are preferably used. For example, UV curable offset inks are mainly composed of pigments, resins, monomers, photoinitiators, and additives. Polyester acrylate, epoxy acrylate, urethane acrylate, and polyester are used as resins. , phenoxydiethylene glycol acrylate, tripropylene glycol diacrylate, trimethylolpropane triacrylate, dipentaerythritol hexaacrylate, etc. are used, and photoinitiators include alkylphenone, acylphosphine oxide, oxime ester, It is an ink that uses a cationic ink. Moreover, in order to improve the printability, a lubricant, a film stabilizer, a cutting agent, etc. may be added.

In addition, although not shown, it is desirable that the concealed printed portion completely conceals the color printed portion in the initial state in order to enhance the design, and misregistration may occur when printing from above the color printed portion. Taking this into consideration, it is preferable that the concealed printed portion be 0.05 to 1.00 mm thicker than the color printed portion. It should be noted that it is not always necessary to uniformly thicken the whole, and the thickness may be partially different depending on the specific character, font, and size of the information to be finally printed.

As a specific condition for discoloration or discoloration of the concealing ink, for example, when heat of 60 ° C. or higher is applied, the color is discolored to a color that is almost transparent, or the color is discolored to a light color that allows the color ink to be visible. After that, an ink that does not discolor or decolor to a degree that is visible to humans under normal circumstances is preferably used. Furthermore, under special conditions, such as cooling to -20°C or less, it is a reversible ink that can be redone if you make a mistake or if your schedule changes. preferable.

Examples of inks having such characteristics include inks composed of a leuco dye, a color developer, and a discoloration temperature adjuster. As color developers, monophenols or polyphenols having substituents such as alkyl groups, aryl groups, acyl groups, alkoxycarbonyl groups, or halogens are used, and alcohols are used as discoloration temperature adjusters. , ketones, esters and the like are preferably used.

By using the concealing ink having the properties as described above, it becomes possible to decolorize or discolor the concealing printed portion by rubbing with silicon rubber or the like due to the frictional heat. In the case of concealing ink that discolors, the color after discoloration may be set to a light color so that the color of the color ink is almost visible, or the color ink and the concealing ink after discoloration may be superimposed. Then, each color may be adjusted so that it can be visually recognized as a color indicating a holiday.

In addition, the specific condition for discoloration or discoloration of the concealing ink is not limited to the temperature change described above, but may be light, electricity, magnetism, chemical reaction, or the like. For example, in the case of a chemical reaction, a pen containing ink containing a substance that decolorizes or discolors the concealing ink is attached to the scheduler. Use after erasing or discoloring the concealed printed part.

FIG. 2(b) shows another embodiment of a cross-sectional view of the desktop calendar taken along line XX' of FIG. 1(b). A difference from the embodiment shown in FIG. 2(a) will be described. In this embodiment, the concealing printed portion has a two-layer structure of a complementary color layer and a concealing layer. For the complementary color layer, by using a color ink that has a complementary color relationship with the color ink, the colors of the complementary color layer and the color printing layer are mixed to make it visible as gray. By stacking layers, there is an effect that the color printed layer becomes more difficult to see.
