Here, it is preferable that the bright pigment is added to the ink for printing the first printing layer 2 and the second printing layer 3 as described below, but the bright pigment is not added. However, it has been confirmed that it has excellent impregnability.

<Base material sheet 1>
As the base material sheet 1, basically the same base material sheet as that used for a known general decorative sheet can be used.
Examples of the paper base sheet 1 include thin paper, titanium paper, and impregnated paper. Examples of the resin-made base sheet 1 include polyolefin resins such as polyethylene, polypropylene, polymethylpentene, polybutene, ethylene-propylene copolymer, ethylene-α-olefin copolymer, and propylene-α-olefin copolymer. Olefins such as ethylene-vinyl acetate copolymer, ethylene-vinyl alcohol copolymer, ethylene- (meth) acrylic acid (ester) copolymer, ethylene-unsaturated carboxylic acid copolymer metal neutralized product (ionomer) Polyolefin resin such as copolymer resin, polyethylene terephthalate, polybutylene terephthalate, polytetramethylene terephthalate, polyethylene naphthalate, polyethylene terephthalate-isophthalate copolymer, 1,4-cyclohexanedimethanol copolymer poly Polyester resins such as ethylene terephthalate, polyarylate and polycarbonate, acrylic resins such as poly (meth) acrylonitrile, polymethyl (meth) acrylate, polyethyl (meth) acrylate, polybutyl (meth) acrylate and polyacrylamide, 6-nylon, 6 Polyamide resins such as 6-nylon and 6,10-nylon, styrene resins such as polystyrene, AS resin and ABS resin, vinyl resins such as polyvinyl chloride, polyvinyl acetate, polyvinyl alcohol, polyvinyl acetal and polyvinyl butyral. , Polyvinyl fluoride, polyvinylidene fluoride, polytetrafluoroethylene, ethylene-tetrafluoroethylene copolymer, ethylene-perfluoroalkyl vinyl ether copolymer and other fluorine-based resins, or the like, or Mixtures of two or more of these, copolymers, composites, it is preferable in that it can be used a laminate or the like.

  Among the above-mentioned various thermoplastic resins, in view of the increasing social interest in environmental problems in recent years, it is not desirable to adopt a resin containing chlorine (halogen) such as polyvinyl chloride resin, It is desirable to use a halogen-based thermoplastic resin. Above all, it is most desirable to use a polyolefin resin or a polyester resin (amorphous or biaxially stretched) from the viewpoints of various physical properties, processability, versatility, economical efficiency and the like. Of these, polyolefin-based resins have been conventionally used as a material for decorative materials that substitutes for polyvinyl chloride resin.

  As the above-mentioned polyolefin-based resin, many kinds are known as already listed, and it may be appropriately selected and used from among them depending on the purpose of use of the decorative material, etc. Most suitable for use is a polypropylene resin, that is, a homopolymer or a copolymer containing propylene as a main component, and specifically, for example, a homopolypropylene resin, a random polypropylene resin, a block polypropylene resin, or the like may be blended alone or appropriately. It is also possible to use a resin or the like in which atactic polypropylene is appropriately blended therein. Further, it may be a copolymer containing an olefin-based monomer other than propylene, and has, for example, a polypropylene crystal part, and an α-olefin having 2 to 20 carbon atoms other than propylene, preferably ethylene, butene-. Examples thereof include a propylene-α-olefin copolymer containing 15 mol% or more of one or more comonomers of 1,4-methylpentene-1, hexene-1 or octene-1. Further, low density polyethylene, ethylene-α-olefin copolymers, ethylene-propylene copolymer rubbers, ethylene-propylene-non-conjugated diene copolymer rubbers, styrene-butadiene copolymers, which are usually used for softening polypropylene resins. A modifier such as a coalesced product or a hydrogenated product thereof can also be added as appropriate.

  The base sheet 1 may include, for example, a colorant, a filler (silica, talc, titanium oxide, barium sulfate, etc.), an ultraviolet absorber, a light stabilizer, a heat stabilizer, an antioxidant, an antistatic agent, and a lubricant, if necessary. One or more selected from various additives (stearic acid, metallic soap, etc.), flame retardants, antibacterial agents, antifungal agents, antifriction agents, light scattering agents, luster modifiers and the like may be added. It should be noted that the base material sheet 1 is often used as an opaque coloring material for concealing variations in color and defects on the surface of a substrate or the like to which the decorative sheet 10 is attached. In order to make the best use of the texture of the surface of the substrate to which 10 is attached, a transparent or semitransparent material may be used.

In particular, the base sheet 1 is preferably a fibrous sheet material such as paper that can be impregnated with a thermosetting resin and has good water absorption, such as thin paper, titanium paper, fine paper, bleached or unbleached kraft paper. It can be illustrated. Of these, titanium paper, which is excellent in both printability and resin impregnation suitability, is most suitable. Further, when it is desired to utilize the texture of the surface of the base material sheet 1, so-called transparent paper having a property of being transparent by impregnation with a thermosetting resin such as a melamine resin can be used. The thickness of the base sheet 1 is not particularly limited, but a base sheet having a basis weight of about ²⁰ to 200 g / m ² is generally used. It is preferably 80 g / m ² .

<First printing layer 2>
The first printed layer 2 is formed on the base sheet 1 by printing such as gravure printing so that the first printed layer 2 has a dot pattern of any of A, B, C, and D shown in FIGS. 2 to 5, for example. Is formed. The dot pattern used is preferably the A pattern. The dot portion is the portion where the ink is attached by printing.

The dot pattern is formed by repeating a dot pattern composed of dots having at least two kinds of diameters. The difference in diameter between the first dot D1 and the second dot D2, which are two types of dots, is 50 μm or more and 120 μm or less.
For example, the first dot D1 is a dot having a diameter of 50 μm or more and 90 μm or less, and the second dot D2 is a dot having a diameter of 150 μm or more and 210 μm or less.

The height of each dot is preferably 25 μm or more and 34 μm or less.
In each of the dot patterns described above, the first dot D1 is located around the second dot D2, and the second dot D2 is further arranged on the outer periphery of the first dot D1. In particular, the A pattern has such a pattern arrangement.
That is, like the pattern A, the first dots D1 are arranged at the four diagonal corners of the second dot D2, and on the left, right, upper and lower sides of the second dot D2, and outside the first dot D1 in the diagonal direction, respectively. A pattern in which the second dots D2 come is preferable. In this pattern, the four sides of the first dot D1 are surrounded by the second dots D2, and the four sides of the second dot D2 are surrounded by the first dots D1.

The distance between the first dot D1 and the second dot D2 is preferably 50 μm or more and 90 μm or less.
In the case where the above-mentioned dot pattern is used to form a picture pattern on the first print layer 2, there are no particular restrictions on the type of the picture pattern, and there are wood grain patterns, stone patterns, cloth patterns, abstract patterns, geometric figures, Any desired pattern such as letters, symbols, etc., or a combination of two or more kinds thereof can be selected as desired.

  The first printing layer 2 can be provided by a usual printing method using a usual printing ink. The type of printing ink is not particularly limited, and may be an oil-based ink, but it is preferable to use a water-based ink in consideration of resin impregnation suitability. Compared with oil-based inks, water-based inks have a better compatibility with the aqueous solution of impregnated resin, and they can be impregnated quickly and uniformly in the subsequent impregnation step, and furthermore, excellent strength is achieved by integration with the impregnated resin. Because you can do it. However, a bright pigment such as titanium oxide is included.

  The type of the above water-based ink is not particularly limited, but it is most preferable to use a binder resin whose main component is casein, emulsion resin and / or latex resin. These binder resins have the property of being hardly water-soluble by passing through a drying process after printing the ink, and are difficult to be redissolved in an aqueous solution of the impregnating resin in a subsequent resin impregnation process, so that the pattern may be damaged. This is because there is no possibility of contamination of the impregnated resin.

The emulsion resin may be, for example, an acrylic resin, vinyl acetate resin, styrene resin, urethane resin, or the like, and the latex resin may be styrene-butadiene resin, acrylonitrile-butadiene resin, methyl methacrylate-butadiene resin, or the like. .
In addition to these casein, emulsion resin and / or latex resin, for the purpose of improving the stability of the ink, for example, water-soluble resins such as polyvinyl alcohol and polyacrylamide, and water-soluble polymers such as polysaccharides and cellulose derivatives. Etc. may be used together.

The pattern forming method is not particularly limited, and may be any printing method such as a gravure printing method, an offset printing method, a screen printing method, a flexographic printing method, a relief printing method, an ink jet printing method. Further, when a solid ink layer is provided for the purpose of coloring the undercoat, as the method for forming the solid ink layer, in addition to the above various printing methods, for example, a roll coating method, a gravure coating method, a rod coating method, a knife coating method, an air knife. It is also possible to use any coating method such as a coating method, a spray coating method, a lip coating method and a die coating method.
The ink preferably contains an inorganic pigment such as titanium oxide or iron oxide as a bright pigment.
The first printed layer 2 has the concealing property by containing the above pigment.

<Second print layer 3>
The second printing layer 3 is printed with an ink containing a pearl pigment to form, for example, a glittering picture layer. The second printed layer 3 is provided for the decorative sheet 10 to impart a design property with a picture having pearl brightness.

  The second printing layer 3 uses, for example, a gravure printing method or an offset printing method by using a printing ink or paint in which a coloring agent such as a dye or a pigment is dissolved or dispersed in a suitable diluting solvent together with a suitable binder resin. It is generally formed by various printing methods such as a method, various coating methods such as a gravure coating method, a roll coating method, and the like. As the binder resin, for example, a urethane resin, an acrylic resin, a vinyl chloride acetate resin, a polyimide resin, a nitrified cotton, a mixture thereof, or the like is often used, but the binder resin is not limited thereto. The type of pattern is arbitrary, for example, a wood grain pattern, a stone grain pattern, a cloth pattern, an abstract pattern, a geometric pattern, letters or symbols, a combination thereof, and the like, and may be a plain solid color.

  As the bright pigment contained in the ink for forming the second printing layer 3, for example, a pearl pigment obtained by coating a natural mica with a metal oxide such as titanium oxide or iron oxide can be preferably used. Metal powder such as aluminum powder can also be used. The glittering pigment has a particle size of 10 to 70 μm. If it is larger than 70 μm, defects such as unevenness and streaks are likely to occur. However, when printing by gravure printing, a pigment smaller than the gravure plate depth is used.

As a printing method, gravure printing, microgravure printing, finisher roll printing, offset printing, ink jet printing, silk screen printing, or the like can be performed. The layer thickness is set so that the coating amount after drying is 1 to 3 g / m ^2, and most preferably 2 g / m ² . If it is less than 1 g / m ² , sufficient glittering property is not exhibited, and if it is more than 3 g / m ² , defects such as omission are likely to occur.
Here, as the gravure plate, a normal gravure plate plated with copper on an iron core, provided with a pattern by etching, and then plated with chrome can be used. It is preferable not to use a screen.

<Medium coat layer 4>
The medium coat layer 4 is formed by coating a transparent resin containing medium as a main component on the second print layer 3. When the resin used for the medium coat layer 4 is a melamine resin, it can be appropriately used from those conventionally used as thermosetting resins. The coating thickness is preferably about 1 to 5 μm.
Here, the case where the above dot pattern is applied to the first printing layer 2 is illustrated, but the dot pattern formed by the above printing may be applied to the second printing layer 3.

(Other effects of this embodiment)
By configuring the print layer with a dot pattern composed of dots having a diameter difference of 50 μm or more, it is possible to stably manufacture the picture layer containing the pearl pigment, which constitutes the second print layer 3. It is possible to have a stable glossiness with respect to the sense of light brightness due to the pearl pigment. In particular, when the first printed layer 2 is formed of the above dot pattern, it is possible to stably obtain an excellent glossiness due to the pearl pigment.

Further, even if the decorative paper is impregnated with a thermosetting resin such as a melamine resin and cured by heating and pressurization, it has good thermosetting resin impregnation performance.
The print layer is preferably formed by gravure printing. At this time, if the screen is not used during the production of the gravure plate, the shape of the cells of the plate will be a shape with good reproducibility, and therefore, the bright pigment will have sharpness after printing, and further, streak, The unevenness can be greatly suppressed.

  Here, it has been confirmed that when the first printing layer 2 is formed of the above dot pattern as in Examples described later, the impregnation property is significantly improved and the pearl brightness is also good. Even when the second printed layer 3 was formed with the above dot pattern, the impregnation property was significantly improved, but regarding the pearl brightness, it is better to form the first printed layer 2 with the above dot pattern. It was

(About high-pressure resin decorative board pressing method)
Next, an example of a decorative board in which the decorative sheet 10 is impregnated with a melamine resin and is heated and pressed and cured will be described. The resin to be impregnated may be a thermosetting resin other than the melamine resin.
FIG. 6 is an explanatory view showing a laminated structure at the time of pressing when manufacturing a high-pressure melamine resin decorative board.

That is, in FIG. 6, reference numeral 11 indicates upper and lower heating plates, reference numeral 12 indicates a heat-resistant cushion sheet, reference numeral 13 indicates a mirror surface plate, and the following materials are laminated in order from the bottom between a pair of mirror surface plates.
Reference numeral 14 is a backer paper. The backer paper 14 is an impregnated paper obtained by impregnating a titanium paper having a basis weight of 55 to 160 g / m ² with 40 to 100% of a melamine resin and drying the titanium paper. Fulfill

Reference numeral 15 is a core paper which is a base material of the melamine resin decorative board. The core paper 15 is obtained by impregnating a paper having a basis weight of 140 to 180 g / m ^{2 with} a phenol resin in an amount of 30 to 1 OO% and drying the paper. The core paper 15 determines the thickness of the melamine resin decorative board, and may be used by stacking several sheets.
Reference numeral 10 is the decorative sheet 10 of the above embodiment, which is impregnated with 40 to 100% of a melamine resin and dried.

When the decorative sheet 10 is impregnated with the melamine resin, it is preferable to add any of a silicone resin, a fluororesin, or a fluororesin dispersion as a release agent to the melamine resin and mix them. However, when the overlay paper 16 described later is used, it is not necessary to add and mix the release agent.
The overlay paper 16 is a transparent resin-impregnated paper obtained by impregnating rayon pulp or nonwoven fabric having a basis weight of 25 to 45 g / m ² with 40% to 300% of a melamine resin and drying. A silicone resin, a fluororesin, or a fluororesin dispersion is added and mixed into the melamine resin as a release agent. It should be noted that this overlay paper 16 has few problems in the structure of the decorative plate even if it is not used.

After stacking in the above state (state of FIG. 6), heat and pressure are applied, maximum temperature 140 ° C. to 150 ° C., pressure 60 kgf / cm ^{2 to} 100 kgf / cm ² , time 15 minutes to 30 minutes, and then heat pressure forming, By cooling for 14 to 60 minutes while applying pressure, the resin between the overlay paper 16 and the backer paper 7 can be hardened to obtain an integrated melamine resin decorative board.

  Here, the thermosetting resin with which the base material sheet 1 of the decorative material is impregnated is not limited to the melamine resin, and is used for the production of a thermosetting resin decorative board configured by impregnating the thermosetting resin. A known thermosetting resin may be used. Specifically, for example, melamine-based resin, epoxy-based resin, diallyl phthalate-based resin, benganamin-based resin, urethane-based resin, alkyd-based resin, unsaturated polyester-based resin, phenol-based resin, urea-based resin and the like. These are generally impregnated into the base material sheet 1 of the decorative material in the form of an aqueous impregnating liquid dissolved or dispersed in water.

  Since the decorative sheet 10 of the present embodiment has a significantly improved impregnation property with respect to the resin, if the decorative sheet 10 of the present embodiment is adopted, a good high-pressure melamine resin decorative board can be manufactured while securing the glitter. You can
