It is not something that is specific to something. The technical idea of the present invention may be modified in various ways within the technical scope specified by the claims stated in the claims.

(Constitution)
As shown in FIG. 1, the resin-impregnated decorative board decorative paper 1 of the present embodiment is partially provided on the base paper 2, the pattern pattern layer 3 provided on the base paper 2, and the pattern pattern layer 3. It includes a liquid-repellent cured film 4. Then, as shown in FIG. 2, a portion of the resin-impregnated decorative board decorative paper 1 not provided with the liquid-repellent cured film 4 (for example, a portion of the pattern layer 3 not covered with the liquid-repellent cured film 4). , The entire base paper 2) is impregnated with the resin 5 (for example, a thermosetting resin), and the resin-impregnated decorative board decorative paper 1 impregnated with the resin 5 is laminated on the base material 6 (for example, a wood base material). The resin-impregnated decorative board 7 is manufactured by being heat-press molded and integrating the resin-impregnated decorative board decorative paper 1 and the base material 6. As a result, the gloss matt expression can be imparted to the portion of the pattern layer 3 covered with the liquid-repellent cured film 4 and the portion of the pattern layer 3 not covered with the liquid-repellent cured film 4. it can.
In addition, another functional layer such as a primer layer for improving adhesiveness should be appropriately provided between the base paper 2 and the pattern layer 3 and between the pattern layer 3 and the liquid-repellent cured film 4. It may be.

(Base paper 2)
The base paper 2 is a fibrous sheet such as paper having excellent water absorption that can be impregnated with an aqueous solution of the resin 5 (thermoplastic resin). For example, thin paper, titanium paper, woodfree paper, bleached kraft paper, unbleached kraft paper and the like can be used. In particular, titanium paper is most preferable in consideration of both printability and resin impregnation suitability. Further, when utilizing the texture of the surface of the base material 6 (wooden base material), so-called transparent paper having a property of becoming transparent by impregnation with the resin 5 (thermoplastic resin) may be used. The thickness of the base paper 2 is not particularly limited, but a base paper 2 having a basis weight of 20 to 200 g / m ² can be used.

(Pattern pattern layer 3)
The pattern pattern layer 3 is a layer formed on the base paper 2 by printing to add a pattern to impart design. As the pattern, for example, a wood pattern, a stone pattern, a cloth pattern, an abstract pattern, a geometric figure, a character, a symbol, or a combination of two or more of these can be used. As the printing ink, ordinary printing ink having no liquid repellency can be used. For example, oil-based ink, water-based ink and the like can be used. In particular, water-based ink is preferable in consideration of resin impregnation suitability. Compared with oil-based inks, water-based inks are more compatible with the aqueous solution of resin 5 (thermoplastic resin), can be impregnated quickly and uniformly in the impregnation process of resin 5, and are more likely to be impregnated with resin 5 (thermoplastic resin). This is because it can be integrated with the resin) to exhibit excellent strength.

The type of water-based ink is not particularly limited, but the one having a binder resin containing casein or an emulsion resin as a main component is most preferable. Binder resins containing these as the main components are difficult to be solubilized by undergoing a drying step after printing the ink, and are difficult to be redissolved in an aqueous solution of resin 5 (thermoplastic resin) in the impregnation step, so that the pattern may be impaired. This is because there is no risk of contamination of the aqueous solution of the resin 5. As the emulsion resin, for example, acrylic resin, vinyl acetate resin, styrene resin, urethane resin and the like can be used. Further, as the latex resin, for example, a styrene-butadiene resin, an acrylonitrile-butadiene resin, a methyl methacrylate-butadiene resin and the like can be used.

In addition to casein and emulsion resins, water-based inks include water-soluble resins such as polyvinyl alcohol and polyacrylamide, and water-soluble substances such as polysaccharides and cellulose derivatives for the purpose of improving the stability of water-based inks. A polymer or the like may be added.
The method for forming the pattern layer 3 (printing method) is also not particularly limited, and for example, a gravure printing method, an offset printing method, a screen printing method, a flexographic printing method, a letterpress printing method, an inkjet printing method, or the like can be used. When a solid ink layer for coloring the base is provided as the pattern layer 3, in addition to the above-mentioned various printing methods, for example, a roll coating method, a gravure coating method, a rod coating method, a knife coating method, and an air knife. Any coating method such as a coating method, a spray coating method, a lip coating method, and a die coating method can also be used.

(Liquid-repellent cured film 4)
The liquid-repellent cured film 4 is a film that is partially formed on the pattern layer 3 and has a property of repelling the aqueous solution of the resin 5. Examples of the resin constituting the liquid-repellent cured film 4, that is, the resin having the property of repelling the aqueous solution of the resin 5, include thermosetting resins having urethane bonds such as two-component curable urethane resins and ionizing radiation curable resins. Curable resin can be used. Examples of the curable resin include melamine-based resin, epoxy-based resin, urea-based resin, phenol-based resin, unsaturated polyester-based resin, diallyl phthalate-based resin, benzoguanamine-based resin, urethane-based resin, aminoalkyd-based resin, and silicone-based resin. Thermosetting resins such as resins, ionization radiation curable resins such as (meth) acrylate resins and unsaturated polyester resins can be used.

As a result, when the resin-impregnated decorative board 7 is formed, the portion of the pattern layer 3 covered with the liquid-repellent cured film 4 and the portion of the pattern layer 3 not covered with the liquid-repellent cured film 4 , A gloss matte expression can be imparted to the resin-impregnated decorative board 7. As the forming position of the liquid-repellent cured film 4, one that is in tandem with the pattern (pattern pattern) formed by the pattern pattern layer 3 can be used. For example, it is formed in a portion of the pattern (pattern pattern) formed by the pattern pattern layer 3 where a matte or glossy texture is desired to be expressed. As a result, the design of the resin-impregnated decorative board 7 can be further improved. The resin for forming the liquid-repellent cured film 4 may be colorless or colored.

Further, silicone oil may be added to the resin for forming the liquid-repellent cured film 4 (liquid-repellent cured film 4). As the silicone oil, for example, non-modified silicone oil, amino-modified silicone oil, epoxy-modified silicone oil, carboxy-modified silicone oil, mercapto-modified silicone oil, carbinol-modified silicone oil, methacryl-modified silicone oil, phenol-modified silicone oil and the like are used. it can. In particular, considering the improvement of reactivity with the resin for forming the liquid-repellent cured film 4, amino-modified silicone oil is preferable. The ratio of the silicone oil contained in the liquid-repellent cured film 4 is preferably 0.01% by mass or more and 15% by mass or less, and most preferably 0.05% by mass or more and 10% by mass or less. If it is less than 0.05% by mass, the "magic repellent property" described later is lowered. If it is larger than 10% by mass, the "silicone oil decorative paper backside set-off property" is lowered.

The film thickness of the liquid-repellent cured film 4 may be 0.5 to 100 μm, but more preferably 1 to 30 μm. If it is 0.5 μm or less, the aqueous solution of the resin 5 (thermoplastic resin) may not be completely repelled and may be infiltrated. Further, if it is larger than 30 μm, film cracking may occur when the film is wound on a roll after printing.

(Resin 5)
As the resin 5, for example, a known thermosetting resin generally used for manufacturing a resin-impregnated decorative board 7 can be used. For example, melamine-based resin, epoxy-based resin, diallyl phthalate-based resin, benzoguanamine-based resin, urethane-based resin, alkyd-based resin, unsaturated polyester-based resin, phenol-based resin, urea-based resin and the like can be used.

The impregnation of the resin 5 is performed with an aqueous impregnating solution (aqueous solution) dissolved or dispersed in water. Further, it may be carried out from the four-sided side of the liquid-repellent cured film or from the two-sided side of the base paper. Further, each side may be impregnated twice, or both sides may be impregnated at the same time. The impregnation rate of the resin 5 (ratio of the weight of the resin 5 to the weight after impregnation) may be 20 to 80%, but more preferably 40 to 70%. Further, in order to obtain the resin-impregnated decorative board 7 having excellent physical properties, it is important that the entire base paper 2 is uniformly impregnated with the resin 4 (thermosetting resin).

(Base material 6)
The base material 6 is a member in which a resin-impregnated decorative paper 1 impregnated with a resin 5 (thermosetting resin) is laminated and integrated with the resin-impregnated decorative paper 1. The type of the base material 6 is not particularly limited, but can be appropriately selected depending on the intended use of the resin-impregnated decorative board 7. For example, wood base materials such as single wood boards, plywood, laminated materials, particle boards, medium density fiber boards, and hard fiber boards, and fibrous base materials such as paperboards, woven fabrics, non-woven fabrics, resin impregnated papers, and resin impregnated cloths. Inorganic base materials such as gypsum board, slate board, calcium silicate board, slag gypsum board, wood wool cement board, slag cement board, lightweight bubble concrete board, glass fiber reinforced concrete board, steel plate, brass board, aluminum board, duralumin board, Synthetic resin bases such as metal base materials such as stainless steel plates, acrylic resin plates, styrene resin plates, ABS resin plates, polycarbonate resin plates, nylon resin plates, polystyrene resin plates, polypropylene resin plates, polyester resin plates, and glass fiber reinforced plastic plates. Materials and the like, or composites or laminates in which two or more kinds of these are combined can be appropriately used.

When laminating the resin-impregnated decorative board decorative paper 1 on the base material 6, it may be laminated via an arbitrary adhesive if necessary, or it may be laminated directly without using an adhesive or the like. You may. Further, if necessary, it can be laminated via a core paper in the same manner as a conventional melamine resin decorative board or the like. The core paper is, for example, a paper in which an appropriate base paper such as titanium paper, bleached kraft paper, unbleached kraft paper, and glass fiber non-woven fabric is impregnated with an uncured thermosetting resin. Here, examples of the thermosetting resin include melamine-based resin, epoxy-based resin, diallyl phthalate-based resin, benzoguanamine-based resin, urethane-based resin, alkyd-based resin, unsaturated polyester-based resin, phenol-based resin, and urea-based resin. Etc. can be used, and may be appropriately selected according to the physical properties required for the target resin-impregnated decorative plate 7. As a specific example, phenol resin impregnated kraft paper or the like, which is widely used as a core paper for a conventional melamine resin decorative board, can be used.
