[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a decorative paper on which a rough surface is represented by, for example, a pressed pattern or the like. The present invention provides a decorative paper on which various information such as a bar code can be recorded by thermal transfer.

[0002]

2. Description of the Related Art Colored paper obtained by mixing one or several types of dyed colored fibers, decorative paper obtained by combining coagulated fiber layers,
Decorative paper made of pulp fiber and cotton, vinylon fiber, etc., mesh paper machine using a cylinder with bamboo cage, decorative paper embossed with bamboo cage eyes, embossed uneven pattern The attached decorative paper is known as a high-grade cardboard with a high decorative effect with various colors and patterns,
For example, it is frequently used for book binding, specifically as a book cover, cover, band seal, or as an envelope, brochure, catalog, label, price tag, tag, and the like.

[0003]

[Problems to be solved by the invention] These decorative papers include:
Various recordings are made according to the application, but the decorative paper has a low smoothness on its surface and does not have sufficient close contact with the thermal transfer ribbon, so that accurate recording by thermal transfer cannot be formed.

In particular, a barcode is usually recorded on paper as a price tag or a tag by thermal transfer. However, fine lines of the barcode are not accurately printed on decorative paper, and a barcode reader is used. Misreading occurs in reading. For this reason, when decorative paper is used as a price tag or a tag, the decorative paper is used as a paper for entering a brand name, etc., the barcode is printed on a paper having another smooth surface, and two tags are used as one. The fact is that they are used in pairs.

On the other hand, the present invention provides a decorative paper which can leave the original high-grade appearance of the decorative paper itself on one side and record various kinds of information such as a bar code on the other side by thermal transfer. The purpose is to:

In particular, when the background color of the decorative paper is a dark color such as black, blue, or dark green, the reflectance of light having a wavelength of 600 to 750 mμ is less than 40%. Even though there is no contrast between the background color and the barcode printing, barcodes cannot be read in the wavelength range of a normal barcode reader, but in the present invention, the background color is dark, such as black, blue, or dark green. It is another object of the present invention to provide a decorative paper that can read a barcode even in such a case.

[0007]

In order to achieve the above object, according to the present invention, the reflectance of light having a wavelength of 600 to 750 m.mu. % To 100% by weight of a polymer having a film forming ability.
This is a decorative paper which can be subjected to thermal transfer recording and has a white opaque coating layer made of a paint containing parts by weight.

By forming such a white opaque coating layer, the reflectance of light having a wavelength of 600 to 750 mμ is 40.
% Or more, desirably 60% or more, so that a barcode can be read by a normal barcode reader.

In the present invention, a normal decorative paper having a rough surface is used as a base material. The decorative paper used as a base material is a thick high-quality decorative paper having a basis weight of 30 to 400 g / m ^2. Paper made of laminated fiber layers, decorative paper made of pulp fiber and cotton or vinylon fiber, etc. And decorative paper with an embossed concavo-convex pattern. Specifically, OK Sand, OK Muse Kaizel, OK Muse Pearl, OK Muse Eddy, OK Muse Elster, OK Golden River (above Abekawa Paper Co., Ltd.
), Rezac, tsumugi, batik (special papermaking
Co., Ltd.), Kinumomi, Artes, Sun Peach, Bill Color (all manufactured by Nisshinbo Co., Ltd.) and the like can be used.

In the present invention, the background color of the decorative paper used as the base material is not limited to dark colors such as black, blue, dark green, dark red, etc., for example, white, yellow, beige, gray, It may be a light color such as pink.

Polymer 10 having film-forming ability formed on one side of a base material made of decorative paper having a rough surface
A white opaque coating layer of a paint containing 300 to 1000 parts by weight of a white pigment based on 0 parts by weight includes, for example, polyvinyl acetate, SBR, starch, casein, an acrylic resin, polyvinyl alcohol, acetylcellulose, nitrocellulose, It is formed of a paint containing butyral resin, alkyd resin, and the like as a film-forming component and containing titanium oxide, calcium carbonate, clay, zinc oxide, aluminum hydroxide, and the like as white pigments.

When the ground color of the base material is a dark color such as black, blue or dark green, a white opaque coating layer provides
In order to make the reflectance of light having a wavelength of 600 to 750 mμ 40% or more, it is desirable to use a white pigment containing titanium oxide as a main component, and contains a white pigment containing at least 50% by weight of titanium oxide. It is preferred to use a paint.

[0013] The thickness of the white opaque coating layer of the paint is such that the uneven surface of the base material made of decorative paper having a rough surface is sufficiently smooth by the white opaque coating layer of the paint. It is formed to a thickness of about 3 to 30 μ.

After forming a white opaque coating layer of a paint containing 300 to 1000 parts by weight of a white pigment with respect to 100 parts by weight of a polymer capable of forming a film on one side of a decorative paper as a base material, the coating layer is formed. Is subjected to a super calender treatment at a linear pressure of 35 to 180 kg / cm to make the surface of the white opaque coating layer a smoothness of 40 to 2000 seconds / 100 cc. Can be further enhanced.

[0015]

According to the present invention, a polymer 100 having a film-forming ability is formed on one side of a base material made of decorative paper having a rough surface so that the reflectance of light having a wavelength of 600 to 750 mμ is 40% or more. White pigment 300 to 10 parts by weight
A white opaque coating layer of a paint containing 00 parts by weight is formed, and the rough surface of the decorative paper is smoothed by the white opaque coating layer. And the surface of the decorative paper are improved, and thermal transfer recording without printing omission can be performed.

In particular, since fine lines such as bar codes are accurately printed by thermal transfer recording, there is no need to print and combine the bar codes on another paper having a smooth surface.

In the decorative paper of the present invention, since the coating layer is formed of a paint containing a large amount of white pigment, the coating layer exhibits white opacity. Even for decorative paper of a ground color such as black, royal blue, dark red or the like, for which recording could not be performed, thermal transfer recording on a white opaque coating layer surface is possible.

Further, in the decorative paper of the present invention, the various colors and patterns of the base material made of the decorative paper having a rough surface are exposed on one side as they are, and the function as the decorative paper is impaired. There is no.
