Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter in which a part of characters, patterns, paintings, etc. is printed by using a hidden ink, and in particular, the hidden ink printing portion emits light by coloring or accumulating light. The present invention relates to a printed material that attracts or impresses with users.

[0002]

2. Description of the Related Art Hitherto, as for printing using a hidden ink, checks, gift certificates, securities such as vouchers are printed with an ink that emits color or fluorescence by irradiating an ultraviolet lamp to prevent counterfeiting. It has been widely used to print characters, patterns and the like. In addition, some printed materials for advertising and publicity are printed with fluorescent ink, but some include those that are handled as polluting substances such as cadmium, and harmless materials are expensive and rarely used. There is.

[0003]

Recently, in addition to printed materials such as newspaper inserts, packaging bags or insert cards for portable dust paper have been widely used as a medium for advertising, and the product name, company name. A method to impress
In addition, for children, picture boxes, play cards, sweets and other packaging boxes,
Printing that attracts interest has come to be desired even for cards printed with characters and the like that are attached as free gifts. It is an object of the present invention to provide a printed matter such as a printed matter for advertisement and a picture book, a play card, etc., which can be impressed and impressed by a viewer.

[0004]

The present invention has been made as a result of studies for solving the above problems, and when printing characters, patterns, paintings, etc., a part of it is used for the sun and household. It is possible to solve by printing with ink that develops color when it is exposed to light such as electric light, or hidden ink such as phosphorescent ink that emits light for the required time when the light is blocked after being exposed to light from the sun, electric light, etc. .

That is, in a normal state, a hidden ink containing a colorless or light-colored photo-reactive substance is used to print characters, patterns, or a part of a painting, without using a special ultraviolet lamp for discrimination. It is a printed matter that develops color when exposed to light such as the sun or household electric light, or when it is cut off after being exposed to light, so that the entire printed matter can be read, or the part printed with hidden ink appears. Polychromatic glass particles are used as a photoreactive substance that develops color when exposed to light, and a phosphorescent substance in which copper is added to zinc sulfide as an activator is used as a substance that stores light and has an afterglow function.

Since the hidden ink used here is generally expensive and the particles of the photoreactive material are larger than the pigment particles of a general printing ink, it is necessary to print a part of characters, patterns or paintings on another substrate sheet. There is no problem even if it is constructed by cutting and punching and cutting and sticking it together. In this case, it is preferable to use an adhesive sheet having a back surface coated with an adhesive. The base material sheet to be printed is not particularly limited, but white high-quality paper, particularly coated paper, gives good results.

[0007]

[Function] For a printed matter in which a part of characters, patterns, paintings, etc. is printed with the hidden ink, the hidden ink printing portion is colored by the light of the sun, electric light, etc. to complete the characters, patterns, paintings. Also, when the light is blocked after being exposed to the light of the sun, electric light, etc., the part printed with the hidden ink emits light, and a part of characters, patterns, paintings, etc. appears.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in accordance with embodiments. [Example 1] A polychromatic glass that develops a pink color when a flower pattern is exposed to light in the center when printing a promotional card enclosed on a portable tissue paper so that it can be seen from the surface during packaging When you print using hidden ink containing particles, it appears as a flower pattern when exposed to sunlight,
A product with a high advertising effect was obtained. A white single-sided coated paper having a basis weight of about 70 g / m ² was used as the base sheet of the advertising card.

[Example 2] A part of a picture such as a picture book was printed by using a luminescent ink containing a phosphor having a afterglow function with copper as an activator in zinc sulfide as a hidden ink. When cut off, a product was obtained in which part of the painting appeared. The phosphorescent ink containing a phosphor having an afterglow function was an ink using a resin medium for silk printing. Also, picture books are normally printed, and part of the painting, such as a character,
After printing flowers, birds, the sun, stars, etc. and adhering them to cut-out or punched-off release paper and attaching them to picture books, we obtained a product that interests readers.

[0010]

EFFECTS OF THE INVENTION Since the present invention is configured as described above, when it is used as a promotional card for a portable tissue paper, a flower pattern or the like appears after it is taken out from a pocket or the like, so that it can be slid off. Instead, it can be brought back to office or home, so you can impress the company name, advertising product, etc. In addition, when it is applied to a picture book using phosphorescent ink, it is expected to emit light, especially when characters, flowers, birds, the sun, stars, etc. are blocked from light, and to make children interested in picture books. It In particular, when it is applied to a seal, a label, etc., it is expected to be used in many applications other than the above.
