DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a matting decorative material used as a surface decorative material for cabinets and the like of furniture and various home appliances as well as interior materials for buildings.

[0002]

2. Description of the Related Art Japanese Patent Laid-Open No. 63-2646 discloses a matte decorative material used as an interior material for a building or a surface decorative material for furniture.
No. 80, after forming a pattern printing layer on a substrate such as a synthetic resin sheet, a surface protection layer of a paint containing resin elastic beads is formed on the surface on which the pattern printing layer is formed. Are known. Such a decorative sheet had a so-called "suede-like" or "velvet-like" matte appearance and good touch.

[0003]

However, when the above-mentioned paint containing the resin bead pigment is applied to a fibrous base material such as paper, the binder component is absorbed by the base material and the resin bead pigment remains as it is. Gloss is reduced due to residual. Moreover, because of the so-called "formation unevenness" in which the absorbency unique to a fibrous base material such as paper varies depending on the location, the degree of gloss reduction varies depending on the location, and there is a drawback that the gloss is noticeable as uneven gloss. In addition, if the amount of resin bead pigment in the coating film increases due to the absorption of the binder resin into the base material, the surface of the coating film increases in irregularities, and the coating film itself becomes porous, so that dirt is easily absorbed and remains. There is also a disadvantage that the stain resistance is reduced.

[0004] In order to solve this drawback, Japanese Patent Laid-Open Publication No.
As in the invention described in Japanese Patent No. 4743, once a substrate such as a biaxially stretched polyethylene terephthalate (PET) film does not absorb a paint, has a smooth surface, and has excellent solvent resistance to dilution and heat resistance. Apply paint containing bead pigment,
Then, a method of applying the coated substrate to paper was developed.
However, in this method, an extra step called lamination is added by one step, and the material cost for PET and the adhesive is increased. Also, as in the invention described in JP-A-2-48936,
A method has also been developed in which a transfer sheet having a resin bead pigment-containing coating film provided as a transfer layer on a peelable support sheet is formed, and then the resin bead pigment-containing coating film is transferred onto paper using the transfer sheet. Was. However, in such a method, an extra step called transfer is also added by one step, and further, there is a time and effort for discarding the support sheet after transfer.

It is made of pulp board, Japanese paper, synthetic paper or other paper, glass fiber, vinylon fiber, polyester fiber, or other nonwoven fabric or woven fabric. As will be described later, the object of the present invention is particularly the air permeability (JIS-P8117) in which unevenness of the penetration of the vehicle and solvent of the paint becomes conspicuous due to uneven gloss and stain resistance of the paint film containing the bead pigment. Gurley-type measuring device) is 7
Less than 0 seconds. If necessary, a material obtained by laminating another substrate on the back surface of the fibrous substrate may be used. As the other substrates such as iron, aluminum, metal foil or plate such as copper, polypropylene, polymethyl methacrylate, Po Li <br/> ethylene terephthalate, polyvinyl chloride, a resin such as ABS resin sheet or plate, Further, a wood board such as a wood veneer, a wood plywood, or the like is used.

The intermediate layer 4 is formed between the surface protective layer 5 made of a coating film containing bead pigments and the fibrous base material 2 before applying the coating material containing bead pigments. Specifically, it is the surface of the fibrous base material as shown in FIG. 2, or the surface of the printed layer as shown in FIG.
As the intermediate layer 4, a crosslinked resin is used. A cross-linked resin is a polymer having a chemical bond that links some points between molecules, a reaction between the side chain functional groups of the polymer, a cross-linking agent that is a monomer having two or more functional groups and a polymer side chain functional group. Or a reaction between monomers having two or more functional groups. Are used. (1) a monomer, prepolymer and / or oligomer having an unsaturated bond or an epoxy group as a functional group, (2) a compound having any one of a hydroxyl group, an amino group, a carboxyl group, a mercapto group, and a polyisocyanate compound;
(3) Sulfur, sulfur chloride and rubbers, (4) novolak resin and hexamethylenetetramine, etc. can be used as appropriate. In particular, from the viewpoint of sealing effect of formation unevenness, adhesion, etc., to a substrate to be printed such as paper or nonwoven fabric formed mainly of cellulose (cellulose) fiber or pulp, a hydroxyl group is used. Compounds having, that is, a polyol compound and a polyisocyanate compound are suitable, and as the polyol compound, polyether polyol, polyester polyol, acrylic polyol, epoxy polyol and the like are used, and as the polyisocyanate compound,
2,4 tolylene diisocyanate, 2,6 tolylene diisocyanate, 1,3 xylylene diisocyanate, 1,4 xylylene diisocyanate, 1,5 xylylene diisocyanate, m-phenylene diisocyanate, p-phenylene diisocyanate , Hexamethylene diisocyanate, 3.3'-dimethyl {4.4 "

Air permeability of the fibrous base material 2 is second or less (JIS-P811
(Measured with a Gurley-type measuring device of No. 7), the coating amount and resin are selected and adjusted so as to be adjusted to 70 seconds or more. The reason for this is that, as a result of various experiments, when a paint containing bead pigment is applied, unevenness in gloss and poor stain resistance due to uneven penetration of the vehicle and solvent of the paint into the substrate to be printed are caused by the coating substrate. There is a correlation with the air permeability, and when the air permeability is less than 70 seconds, the formation unevenness and the unevenness of permeability are easily conspicuous as gloss unevenness of the coating film of the paint containing the bead pigment, and the air permeability exceeds 70 seconds. When,
Even if there is formation unevenness and permeability unevenness, almost glossiness of the coating film,
This is because the poor stain resistance was found to be inconspicuous. As a method for applying the fibrous base material, a printing means or a coating means such as a gravure coating (or printing) method, a silk screen printing method, a roll coating method, and a fountain coating method is used.

The vehicle 7 in the paint containing the resin bead pigment for forming the surface protective layer 5 is appropriately selected depending on the material of the base material, the use of the decorative material, and the like. Examples thereof include polyvinyl chloride, polyvinyl acetate, and polyvinyl chloride. Cellulose resins such as vinyl-vinyl acetate copolymer, cellulose acetate and cellulose nitrate; thermoplastic resins such as acrylic resins such as polymethyl acrylate, polybutyl acrylate, polymethyl methacrylate, polybutyl methacrylate, etc. A thermosetting resin or ionizing radiation (electron) in which an acrylate such as urethane acrylate or polyester acrylate having an unsaturated bond or an epoxy group, a prepolymer such as unsaturated polyester, and / or a monomer such as various acrylates are appropriately mixed. Ray, ultraviolet ray, etc.) curable resin,
A two-component curable urethane resin composed of a polyol and an isocyanate can be used. As the vehicle, a two-liquid curable urethane resin or an acrylic resin is preferable from the viewpoint of the fixation of the bead pigment, that is, the property of the bead pigment not falling off in the surface protective layer.

The bead pigment 6 in the surface protective layer 5 includes
Known bead pigments such as resin beads, glass beads, and shirasu balloons can be used. However, from the viewpoint of the abrasion resistance and abrasion resistance of the coating film surface, and the difficulty of falling off the bead pigments, Japanese Patent Publication No. 40-36816. Resin bead pigments described in JP-A-51-10251, JP-A-63-264680 and the like are desirable. The Representative examples of the resin bead pigments are those granulated by dispersing a fine powder of pigment or dye in a synthetic resin, for _{example, Fe 2 0 3, Ti0 2} ,
Fine powder of pigments and dyes such as CaCO ₃ and quinacridone
In elastic resin such as urethane resin, acrylic resin, epoxy resin, polyester resin, nylon resin, fluororesin, vinyl chloride-vinyl acetate copolymer, or plasticizer, stabilizer, interface if necessary It is dispersed and granulated by adding an activator or the like, and has a spherical shape or a shape similar thereto, and has a most frequently occurring particle size of about 5 to 80 μm. In particular, in order to express a suede-like or velvet-like appearance, the most frequent particle size is about 15 to 80 μm, and in order to express the surface gloss of a wood grain board (particularly, spring wood), the most frequent particle size is 15 μm. About 80 μm is good.

The coating material for forming the surface protective layer is preferably prepared by dispersing about 5 to 300 parts by weight of a bead pigment per 100 parts by weight of a vehicle from the viewpoint of the dispersibility and fixability of the bead pigment. It is preferable to disperse 40 to 60 parts by weight of a bead pigment with respect to 100 parts by weight of a vehicle. A coloring pigment other than the bead pigment and an extender pigment may be added to the paint containing the bead pigment as necessary.

The coating means for forming the surface protective layer 5 with a paint containing bead pigment on the substrate 2 includes gravure coating (or printing), silk screen printing, roll coating, fountain coating, and the like. Printing means or coating means such as gravure coating (or printing) is particularly preferable, and is usually formed to a thickness of about 10 to 240 μm.

The pattern layer 3 in the matte decorative material according to the second aspect of the present invention is made of, for example, a cellulose resin such as nitrocellulose, an acrylic resin such as polymethyl methacrylate, a vinyl chloride-vinyl acetate copolymer resin, an alkyd resin. It is formed by a coloring ink using a vehicle similar to the printing ink used when forming the pattern printing layer by the above method. The colored ink forming the picture layer may contain a brilliant pigment such as a pearl pigment or a metal powder.
As a picture, for example, when expressing a leather-like appearance such as suede, the pattern on the leather surface, when expressing the appearance of a wood grain board, the pattern on the wood grain board surface such as zelkova, cedar, cypress, and the texture of the cloth surface Is expressed by using a plate in which the surface pattern of the fabric is made by a known photoengraving technique. Also, a solid pattern or an abstract pattern may be used.

The picture layer 3 is formed by, for example, ordinary printing means such as gravure, gravure offset, and silk screen, handwriting, electrophotography, ink jet printing, and the like. In the case of a wood-patterned picture layer, an ink containing a brilliant pigment such as pearl ink may be used to express the inherent luster of the wood-grain board, that is, “shine”.

[0015]

The matte decorative material of the present invention is obtained by laminating an intermediate layer provided by a paint composed of a crosslinked resin and a surface protective layer provided by a paint containing a bead pigment on a fibrous base material. The intermediate layer fills and seals the voids between the fibers of the fibrous substrate to be printed, and penetrates the liquid components (at least at the time of application), such as the vehicle and the solvent, in the coating components and penetrates like the bead pigment. Prevents separation from hard-to-react components. Accordingly, it is possible to prevent the ratio of the bead pigment in the coating film from being distributed depending on the location, thereby preventing gloss unevenness, corresponding to the distribution (unevenness) of the paint permeability caused by the uneven formation of the base material to be printed. Also, by reducing the amount of binder resin absorbed into the base material, it is possible to prevent the resin bead pigment in the coating film from unnecessarily increasing. However, since the surface unevenness does not unnecessarily increase and the coating film itself can be prevented from being made porous, dirt components on the coating film surface are less likely to be absorbed and remain, and stain resistance is improved.

Further, by applying a physical property of the laminated body provided with the intermediate layer with air permeability (JIS-P8117, Gurley air permeability tester) to be 70 seconds or more, especially to the inside of the substrate. Of the coating liquid can be reliably prevented and the smoothness of the substrate surface can be improved.

In addition, by forming the intermediate layer from a two-pack curable urethane resin comprising a polyol compound and a polyisocyanate compound, strong adhesion to a substrate to be printed and a pattern layer, particularly, mainly composed of cellulose fibers, is provided. Thus, it is possible to obtain strong solvent resistance to the coating liquid.
