The invention concerns a method of manufacturing a decorative paper and decorative paper.

Decorative coating, the so-called decorative paper, special paper for finishing surfaces of wood materials. Because of the high requirements to the appearance to the decorative paper is also the most demanding. For optimum printing properties of paper requires a particularly high formation, smoothness and dimensional stability. When processing impregnation with synthetic resin requires its uniform penetration into the paper. Impregnation with subsequent pressing is used primarily to reduce the susceptibility of the surface to mechanical, thermal and chemical loads (e.g., abrasion, scratching, water, solvent, water vapor and solvent vapours).

There is an interest to reduce the ability of paper to absorb the resin. For this, in principle, two ways.

On the one hand, attempts were made to seal the decorative paper and leave it, therefore, smaller cavities which may be filled with resin. This effect has already been indicated, for example, in the preamble to the description in DE 10134302 C1. However, this method has not been widely put into practice.

Known also another way of reducing the ability of the decorative is the first paper to absorb the resin. After fabrication of decorative paper you can coat it with glue. Here on the surface in the "online" or "off-line" applied predominantly acrylate dispersion. Due to this, the surface of the paper partially sealed, and resin worse penetrates into the paper. You can also decrease while the capillary action of the paper fibers.

In particular, the latter method is only applicable for securities that are not sealed. Before printing, you must decide whether to use paper with less ability to absorb resin (saving tar paper) or not.

Here can help invention, which aims at the creation of a method of manufacturing decorative paper, which does not require pre-selection of paper, including "saving tar paper.

According to the invention this problem is solved by a method with the distinctive signs of paragraph 1 of the claims. Due to the fact that on the paper after printing the decoration is painted aliphatic, polycarbonatea, anionic polyurethane dispersion for the manufacture of decorative paper can be used both traditional and saving tar paper. Accordingly, and in particular, what is new is that configuring savings resin in the here described method occurs after printing and that the use is : aliphatic, polycarbonatea, anionic polyurethane dispersion. So far, such dispersion is not used when decorating paper. Due to the application after printing increases the flexibility of the printed base paper from the printer. Paper making is always determines the minimum number of appropriate settings. Hence, the minimum withdrawal amount that restrict the ability of the printer.

However, it is known the use of polyurethanes as lacquer systems with or without a printed decor paper. In contrast to the invention it is, however, lucky to which you want to add the hardener. These painted surfaces are a barrier from the environment; the paper is no longer saturated or not finished in any other way, and masked on the materials. This measure here is not provided.

As another preferred side effect of the way also increases the light resistance is made according to the invention a decorative paper. To improve the light fastness of the decorative paper according to the prior art on decorative paper before pressing overlap, for example, overlays, also covered acrylate dispersions. In these measures in the proposed method there is no need.

Other preferred variant of the method followed by, in particular, the features of dependent claims.

Another object of the invention is to create a decorative paper, which would have increased lightfastness and could profitably be made.

According to the invention this problem is solved by means of decorative paper to the distinctive features of paragraph 11 of the claims. Due to the fact that the decorative paper contains at least one core, a printed layer and put in the core of aliphatic, polycarbonatediol, anionic polyurethane dispersion can be created decorative paper, which has a high light fastness and can profitably be produced, since, as the source material of the core can be used as a "saving"and "not saving tar paper.

Other preferred variants of decorative paper followed by, in particular, from the characteristics of the dependent claims.

Other characteristics and advantages of the invention are explained with the help of the following description of preferred examples of its implementation with reference to the accompanying tables and drawings, which represent:

- table. 1-5: the MSDS on BayhydrolXP 2606;

- table. 6-8: passport product Bayhydrol;

- figure 1: a diagram of the way;

- figure 2: schematic cross-section of the decorative the second paper according to the invention.

On the paper with the printed decoration is painted aliphatic, polycarbonatea, anionic polyurethane dispersion. This may be the product BayhydrolXP 2606 company "Bayer" or another comparable product (Bayhydrol is a registered trademark of the firm Bayer AG, 51373 Leverkusen). Polyurethane dispersion decreases capillary action, and polycarbonate causes the adhesion of the dispersion in capillaries, which due to this certain way constrict. Decisive for the further processing of paper pH indicator is set due to the concentration of anions. Aliphati improve the light fastness.

After application is not visible color change of base paper with a printed decor. Thus, the printed product can be manufactured to choose from in the setup savings resin" or "standard" without the need for color matching. The latter is required when using saving tar paper due to a change in absorption of ink when printing.

Aliphatic, polycarbonatea, anionic polyurethane dispersion, in particular the product BayhydrolXP 2606, mixed in a ratio of 25 parts to 75 parts (mass parts) of water and is applied to the seal with a dry mass of about 5 g/m2. These settings are approximate values and may vary for different securities. Application of Khujand is realized or gravure printing through the background of the cylinders in the last printing unit in the "online", either "off-line" other appropriate manner, for example in the coating section.

In tables 1-8, see the safety data sheet and the data sheet for the product aliphatic, polycarbonatea, anionic polyurethane dispersion, in particular dispersion, distributed under the brand name Bayhydrol. These are the properties used preferably for the proposed method aliphatic, polycarbonatediol, anionic polyurethane dispersion. It should be noted that we are talking only about the preferred dispersion. In principle, considered, of course, any other aliphatic, polycarbonatea, anionic polyurethane dispersion.

1 schematically depicts the proposed method.

Figure 2 in schematic cross-section depicted produced offered by way of decorative paper. Basically, it includes a core 1, a printed layer 2, introduced in the core 1 of aliphatic, polycarbonatediol, anionic polyurethane dispersion 3 and, in particular, a resin or entered particles 4 resin.

The proposed method may particularly preferably be used in the following cases as examples.

Special advantages arise from the paint with metallic effect, in particular, the so-called mother-of-pearl colors.

Important aesthete the ical property decors printable mother-of-pearl paints, is owing to this gloss. It greatly depends on the amount deposited pearlescent pearlescent pigments in the paint. In the case of printing pearlescent pigments as a monochrome hue they usually are fixed printed at the top of the mixture as a binder. The number of pigments cannot be increased arbitrarily, since the paper must maintain the ability to impregnation. Too many leads to partial sealing surface, and the resin is not sufficiently penetrates into the paper, which leads to defects impregnation and, thereby, to a too high percentage of marriage. On the other hand, the degree of gloss depends on the fluidity and curing the resin. Too fast curing causes too small brilliance since the resin during the pressing insufficient spreads and takes (brilliant) the structure of the pressing sheet. In the worst case leads to staining, which also leads to marriage.

The proposal to increase gloss and prevention of defects impregnation are described in the publication EP 1361074 B1. Application of the alkaline solution has a positive effect on the fluidity of the resin. However, the substance should be applied separately.

The increase of the degree of gloss can be achieved also due to the fact that the formula for fixation of pigments is amenaide aliphatic, polycarbonatediol, anionic polyurethane dispersion. With respect to the described in paragraph 1 of the claims of the stages of the method, this means that the printing of the decoration on paper (stage i) is carried out containing pearlescent pigments of paint. Then applied to aliphatic, polycarbonatea, anionic polyurethane dispersion (phase ii).

Compared with EP 1361074 B1 product can be produced with the printing section is smaller, which increases flexibility and reduces costs, such as energy consumption.

The gloss thus obtained surface is very high. If necessary, can be achieved a higher degree of gloss compared with glitter obtained using the steps described in EP 1361074 B1 substances. In addition, the paper becomes less susceptible to variances in the manufacturing process during impregnation and pressing.

Special advantages arise also in connection with so-called flat position.

The problem for further processing of the impregnated paper is that her hand straight. Expert calls this behavior Curling. It arises from the fact that paper can be made fully symmetrical. Asymmetry is enhanced by one-way sealing. In addition, the Curling is also dependent on environmental conditions, especially humidity without the ha premises, which handles paper. Preferably, however, the flat position paper, i.e. a small Curling.

In the prior art specialist there are various ways to reduce Curling. To minimise either the indoor climate is maintained over wet or dry paper before winding or after unwinding moistened with water from the reverse side.

Also in this case can help the proposed method and decorative paper. By applying an aliphatic, polycarbonatediol, anionic polyurethane dispersion on the reverse side of the paper decreases the asymmetry, at least, the paper with the printed decor. In particular, due to dispersion in the paper are also properties such as savings resin and enhanced flexibility.

Special advantages arise also in connection with the so-called opacity.

Decorative paper should be sufficiently opaque to chipboard nothing shone. The opacity depends on the amount of Tio2introduced in the paper. If you want to increase the opacity, then introduce more TiO2. However, this is possible only with simultaneous increase of the density, because the grid paper fibers cannot hold arbitrarily many TiO2. Paper becomes less stable, and its tensile strength is reduced.

Also in this case, due to the proposed method and decorative paper can be achieved benefits. TiO2can be as ink printed on the actual paper. This overprint is sealed by seal from the top of aliphatic, polycarbonatediol, anionic polyurethane dispersion. As a result of its curing after printing increases the breaking strength of paper. At equal density can be paper with high opacity and possessing at the same time, the above-described advantages.

Special advantages arise also in connection with the growth of paper.

In particular, in the manufacture of laminate flooring, the growth of paper during impregnation is the Central theme. Individual panels should have expected width; the tiles must be square. A special requirement is pressed simultaneously with the imprint of the porous structure. In the prior art, it is due to the fact that the growth of the paper web on the basis of absorption of the resin is determined empirically and is recorded in the print data. Fluctuations in behavior with increasing fluctuations of the production process can cause considerable marriage. To ensure balanced growth of the paper, it should be taken from the middle of the paper machine, so that the latter could not be used to the full width as the paper machine can also be twice the width of the processing machine.

T is the train in this case due to the proposed method and decorative paper can be achieved benefits. By applying the appropriate number of aliphatic, polycarbonatediol, anionic polyurethane dispersions growth of paper can be reduced from the current 1.5 per cent to almost 0. Cured after printing aliphatic, polycarbonatea, anionic polyurethane dispersion captures the width of the paper. During the impregnation of the paper is no longer growing.

Typically, aliphatic, polycarbonatea, anionic polyurethane dispersion is applied to the printed side. As shown by the use of "flat position", the application may be preferable also on the reverse side of the paper.
