Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a printed matter having an information display layer for displaying information in a raised manner and a method for producing the same.

[0002]

2. Description of the Related Art Conventionally, barco printing and foaming printing have been known as printing in which information is raised in a concavo-convex shape, and these are applied to a book cover, Braille printed matter, and the like. Burco printing is printing using resin powder such as permanent gloss manufactured by Verco Type, Inc. in the United States. FIG. 4 is a cross-sectional view showing an example of the information display layer 12 formed by barco printing.

First, predetermined information is printed on the base material 11 by offset printing, letterpress printing or the like to form the information layer 12a. Next, an adhesive (not shown) is imprinted on the information layer 12a, and the above-mentioned resin powder is applied to the surface of the adhesive to remove the excess. It is then placed in a furnace to heat and then cool. By this heating, the resin powder is raised by about 0.1 mm to form the raised layer 12b.

Foaming printing is printing in which a foaming ink is printed and then heated to raise (foam) the ink. This ink and printing method include (1)
Print with an ink in which a dye is added to a water-soluble foaming agent in an amount of about 10%, pre-dry at 60 ° C or lower, and then at 1 to 105 to 120 ° C.
~ 2 minutes heating, (2) printing with an ink containing a foaming agent encapsulated in PVA capsules, heating at 110 ° C for 1 minute, (3) printing with a resin ink containing a foaming agent, 120 ~ It is known to pass through a furnace at 140 ° C. The portion printed with these inks is raised by about 0.15 mm to 0.2 mm by heating. FIG. 5 shows an example of the information display layer 22 formed on the base material 21 by foam printing.

[0005]

However, the above-mentioned conventional printed matter has the following problems. The shape of the braille in the braille print is ideally a substantially columnar shape with rounded corners, but the information display layer 12 by barco printing has a small amount of protrusion and has a gentle slope as shown in FIG. It had a shape. For this reason, the shape is not suitable for braille because it is not irritating to touch and requires skill to read it even if it is applied to braille.

On the other hand, the information display layer 22 formed by foam printing is
The amount of protrusion is larger than that of the information display layer 12, and a shape suitable for tactile reading can be obtained. However, the information display layer 22
Had a lack of abrasion resistance and could be damaged or peeled off from the base material 21.

The present invention has been made to solve the above problems, and provides a printed matter having an information display layer having excellent tactile readability and high abrasion resistance, and a method for producing the same. To aim.

[0008]

In order to achieve the above-mentioned object, the means for solving the printed matter according to the present invention is to mix a heat-raising material rising by heating and melting with an additive material having a higher melting point than the heat-raising material. The heat-promoting material is heated and melted to raise and display information, and at least a part of the additive material is provided with an information display layer disposed on the heat-protruding material. And

The solution of the method for producing a printed matter comprises a first step of forming an adhesive layer on an information display layer for displaying information,
A second step of adding a material obtained by mixing a heat-raising material rising by heating and melting and an additive material having a melting point higher than that of the heat-raising material onto the adhesive layer; A third step of melting and raising the raised material.

[0010]

In the solution of the present invention, when the material obtained by mixing the heat-raising material and the additive material having a higher melting point than the heat-raising material is heated, the heat-raising material is melted and raised,
The additive material is not melted and is placed on top of the raised thermal bump material. As a result, an appropriate frictional resistance is obtained on the surface of the information display layer, and the readability is improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a printed material and a method for manufacturing the same according to the present invention will be described below with reference to the drawings. Figure 1
FIG. 1 is a plan view showing a passbook which is an example of a printed matter according to the present invention. An area 31a for displaying a bank name and an area 31 for displaying a subject name on the base material 31 of the passbook 30.
An information display layer 32 in which information is displayed in Braille is provided in b (hatched area in FIG. 1). FIG. 2 is a sectional view showing the configuration of an embodiment of the information display layer 32. The information display layer 32 is a layer in which information is raised and displayed so that the information can be viewed and touched.

The information display layer 32 is an information layer 33 provided on the base material 31 by printing or the like and displaying predetermined information.
And a raised layer 34 provided on the upper layer. Further, the raised layer 34 includes a base layer 34a,
It is composed of a raised piece 34b arranged on the upper portion of the base layer 34a. The base layer 34a is formed of a heat-raising material that rises by heating and melting, and the raised pieces 34b are
It is formed of a material having a higher melting point than the heat-raising material.

Next, a method of forming the information display layer 32 will be described with reference to FIG. First, the information layer 33 is formed on the base material 31 such as paper by offset printing, letterpress printing or the like ((a) in the figure). Next, an adhesive layer 35 is formed on the upper layer of the information layer 33 ((b) in the figure), and the heat-raising material and a material having a melting point higher than that of the heat-raising material (hereinafter referred to as " The material 36 mixed with (additional material)) is sprinkled, and the excess is paid ((c) in the figure). Here, examples of the heat-raising material include the above-mentioned permanent gloss manufactured by Verco Type Co. of the US. Further, as the additive material, acrylic resin, epoxy resin, polyamide resin, butyral resin, PVA, titanium oxide, precipitated barium sulfate, calcium carbonate, calcium hydroxide, aluminum hydroxide,
Examples include microbaron and microsilica. Further, these substances can be used alone or in combination of two or more kinds. The additive material preferably has substantially the same shape (grain shape) and substantially the same specific gravity as the heat-raising material, and more preferably a material having high wear resistance.

Next, this is placed in a furnace and heated. By this heating, the heat-raising material is melted and raised, and the base layer 34a
To form. Also, the additive material is placed on top of the thermally raised material that is not melted and raised to form raised pieces 34b. As a result, the raised layer 34 is formed ((d) in the figure). Further, after heating, it is cooled and the shape of the raised layer 34 is maintained.

Information display layer 3 formed as described above
No. 2 is superior in abrasion resistance to that obtained by conventional foam printing. Furthermore, since the upper surface of the information display layer 32 is formed in a concavo-convex shape by the raised pieces 34b, it has an appropriate frictional resistance,
It gives a rough texture. Therefore, it is possible to form a highly readable shape that cannot be obtained by the conventional barco printing.

Further, since the passbook 30 is mechanically processed by a bookkeeping machine or the like, when forming Braille on the passbook 30, it is preferable that the amount of protrusion is as small as possible. Here, the information display layer 32 does not have a large amount of protrusion like the information display layer 22 formed by foaming printing and has a frictional resistance suitable for tactile reading, and thus is suitable for use in Braille formed on the passbook 30. Is. If Braille is formed on the passbook 30, the bank name etc. of the passbook 30 can be easily read when the visually impaired person uses the passbook 30, so that the bankbook of another financial institution can be mistaken for the financial institution. It can be contributed to the protection of the visually impaired by not showing it. Further, if the information display layer 32 is applied to a general printed matter, it is needless to say that the information can be given a three-dimensional effect and the catch-eye effect can be enhanced as in the conventional case.

Although one embodiment of the present invention has been described above, the present invention is not limited to the above embodiment,
Various modifications are possible without departing from the spirit of the invention. Although the passbook 30 is given as an example of the printed matter to which the present invention is applied, the present invention is not limited to this, and various types such as a package of a product, a business card, a poster, a cover of a catalog or a book, a letterhead, a guarantee certificate, a certificate of commendation, etc. Can be widely applied to printed matter. Further, the information is not limited to Braille, and can be applied to various information such as characters, figures, symbols, patterns and pictures.

[0018]

According to the present invention, information is raised by a heat-raising material to be displayed, and an information display layer having an appropriate frictional resistance is formed on the upper surface of the additive material.
