The coated laminate of the present invention is applicable to the surface decoration of building interiors (such as inner wall surfaces). 【0013】 [Interior Material Layer] The interior material layer in this invention contains 200 to 2000 parts by weight of extender pigment per 100 parts by weight of resin component. Such an interior material layer can produce a low-gloss and subdued finish and can be formed by applying (painting) the interior material containing the above resin component and extender pigment. In this invention, "α to β" is synonymous with "α or greater and β or less". 【0014】 Resin components in interior materials play a role in immobilizing powders and granules such as extender pigments. Examples of resin components include cellulose, polyvinyl alcohol, ethylene resin, vinyl acetate resin, polyester resin, alkyd resin, vinyl chloride resin, epoxy resin, acrylic resin, urethane resin, acrylic silicone resin, fluororesin, etc., or composites thereof. These can be used individually or in combination of two or more. Examples of resin component forms include water-soluble resins, water-dispersible resins (resin emulsions), solvent-soluble resins, solvent-free resins, non-water-dispersible resins, and powder resins. Among these, water-soluble resins and / or water-dispersible resins are preferred, and embodiments containing water-dispersible resins are particularly preferred. Water-soluble interior materials can be obtained by using water-soluble resins and / or water-dispersible resins. Furthermore, these resin components may be either crosslinking-reactive or non-crosslinking-reactive. 【0015】 Extender pigments in interior materials are components that contribute to reducing gloss, and further contribute to providing a natural texture and improving paintability. Examples of extender pigments include heavy calcium carbonate, light calcium carbonate, kaolin, clay, earthenware clay, china clay, diatomaceous earth, hydrated fine silica, talc, barite powder, barium sulfate, precipitated barium sulfate, barium carbonate, magnesium carbonate, silica powder, resin powder, resin beads, aluminum hydroxide, etc., and one or more of these can be used. The average particle size of the extender pigment is preferably less than 50 μm, more preferably 0.5 to 45 μm, and even more preferably 1 to 40 μm. The average particle size of the extender pigment is a value measured by a laser diffraction particle size distribution analyzer. 【0016】 The proportion of the extender pigment is 200 to 2000 parts by weight per 100 parts by weight of the solid content of the resin component, preferably 300 to 1800 parts by weight, more preferably 400 to 1600 parts by weight, and even more preferably 500 to 1500 parts by weight. A proportion of extender pigment above the lower limit is advantageous in terms of reducing gloss, imparting a natural texture, and improving paintability, and is also advantageous when forming a relatively thin and flat coating. A proportion of extender pigment below the upper limit is advantageous in terms of suppressing coating cracking. 【0017】 In addition to the above components, interior materials may also contain aggregates. Aggregates are components that contribute to providing a natural texture and improving paintability. Examples of aggregates include crushed marble, granite, serpentine, fluorite, crushed feldspar, silica, silica sand, crushed ceramics, crushed glass, glass beads, crushed resin, resin beads, metal particles, or materials with colored coatings on their surfaces. These can be used individually or in combination of two or more types. 【0018】 In this invention, colored aggregate may be included as the aggregate. Any aggregate that is visible in some color can be used as the colored aggregate. The color of the colored aggregate may be, for example, naturally derived or artificially imparted. By using colored aggregate, the color development of the interior material layer can be enhanced, making it possible to impart a desired color. 【0019】 The aggregate has a larger average particle size than the extender pigments and coloring pigments described later, preferably 0.05 to 3 mm, more preferably 0.06 to 1 mm, even more preferably 0.07 to 0.5 mm, and particularly preferably 0.075 to 0.2 mm. Having such an average particle size allows for the formation of a highly aesthetic interior material layer with a relatively small application amount, and is also advantageous in terms of thinning and reducing the weight of the interior material layer. The average particle size of the aggregate is obtained by sieving using a metal mesh sieve specified in JIS Z8801-1:2000 and calculating the average value of the weight distribution. 【0020】 The composition ratio of the aggregate is preferably 20 to 2000 parts by weight, more preferably 50 to 1600 parts by weight, even more preferably 100 to 1400 parts by weight, and particularly preferably 200 to 1200 parts by weight, per 100 parts by weight of the solid content of the resin component. When the composition ratio of the aggregate is above the lower limit, it is advantageous in terms of imparting a natural texture and improving paint workability. When the composition ratio of the aggregate is below the upper limit, it is advantageous in terms of suppressing cracking of the coating and is also advantageous when forming a relatively thin and flat coating. From this viewpoint, the weight ratio of extender pigment to aggregate (extender pigment:aggregate) is preferably 95:5 to 20:80, more preferably 90:10 to 40:60, and even more preferably 85:15 to 50:50. 【0021】 In addition to the above components, interior materials may also contain coloring pigments. These coloring pigments contribute to the color development and opacity of the interior material layer. The use of coloring pigments makes it possible to impart a desired color to the interior material layer. 【0022】 Examples of coloring pigments include titanium dioxide, zinc oxide, carbon black, graphite, black iron oxide, iron-manganese composite oxide, iron-copper-manganese composite oxide, iron-chromium composite oxide, iron-chromium-cobalt composite oxide, copper-chromium composite oxide, copper-manganese-chromium composite oxide, copper-magnesium composite oxide, bismuth-manganese composite oxide, red iron oxide, molybdate orange, permanent red, permanent carmine, anthraquinone red, perylene red, quinacridone red, yellow iron oxide, titanium yellow, first yellow, benzoimidazolone yellow, chromium green, cobalt green, phthalocyanine green, ultramarine, Prussian blue, cobalt blue, phthalocyanine blue, quinacridone violet, dioxazine violet, aluminum pigment, pearl pigment, etc. These can be used individually or in combination of two or more. The average particle size of the coloring pigment is preferably 2 μm or less, more preferably 0.01 to 1 μm. The average particle size of the coloring pigment is a value measured by a laser diffraction particle size distribution analyzer. 【0023】 The composition ratio of the coloring pigment is preferably 1 to 200 parts by weight, more preferably 5 to 180 parts by weight, even more preferably 10 to 160 parts by weight, and particularly preferably 20 to 150 parts by weight, per 100 parts by weight of the solid content of the resin component. When the composition ratio of the coloring pigment is above the lower limit, it is favorable in terms of color development and opacity. When the composition ratio of the coloring pigment is below the upper limit, it is favorable in terms of suppressing film cracking and imparting a natural texture. When coloring pigment and coloring aggregate are used in combination, the combined color development of these materials becomes possible, and texture, naturalness, fineness, etc., can be enhanced. 【0024】 Interior materials may also contain components other than those listed above, as long as they do not significantly impair the effects of the present invention. Examples of such components include thickeners, film-forming aids, leveling agents, wetting agents, plasticizers, antifreeze agents, pH adjusters, preservatives, antifungal agents, antialgal agents, antibacterial agents, dispersants, defoaming agents, adsorbents, fibers, water repellents, hydrophilic agents, crosslinking agents, coupling agents, ultraviolet absorbers, light stabilizers, antioxidants, catalysts, solvents, and water. Interior materials can be manufactured by uniformly mixing the above-mentioned resin components, extender pigments, and, if necessary, each of the above components, by conventional methods. 【0025】 The interior material layer in this invention can be formed by applying and drying the interior material to a surface to be coated, such as the interior wall surface of a building. The interior material layer can be formed as a new coating by painting it at the same time as the transparent coating material. Alternatively, the interior material layer may already exist as an old coating before painting the transparent coating material. 【0026】 Examples of substrates that make up the surface to be coated include concrete, mortar, porcelain tiles, fiber-reinforced cement boards, cement calcium silicate boards, slag cement perlite boards, cement boards, ALC boards, siding boards, gypsum boards, plywood, extruded boards, steel plates, and plastic boards. The surfaces of these substrates may have undergone some kind of surface treatment (for example, treatment with putty, sealer, surfacer, filler, etc.), or they may already have a paint film applied to them, or have wallpaper or the like attached. When using primers such as sealers, surfacers, and fillers, their color tone can be set to an approximate color (matching color) of the interior material. 【0027】 In the painting of interior materials, for example, tools such as sprayers, rollers, brushes, spatulas, and scrapers can be used. Specifically, when applying the interior material to the surface to be painted, for example, tools such as sprayers, rollers, spatulas, and scrapers can be used. The shape and amount of the interior material when applied to the surface to be painted can be appropriately set according to the desired finish state, aesthetic properties, etc. Next, when spreading the applied interior material, for example, tools such as spatulas, scrapers, and rollers can be used. Among these, when using a spatula, scraper, etc. when spreading the interior material, it becomes easier to obtain a flat interior material layer by leveling the painted surface. In the present invention, it is desirable to use a spatula at least when spreading the interior material, and it is more desirable to use a spatula when applying the interior material to the surface to be painted and when spreading the interior material. When spreading the interior material, the painted surface can also be leveled while supplying water or a solvent to the painted surface by spraying or the like. 【0028】 The coating amount (in terms of solid content) of the interior material is preferably 80 - 3000 g / m 2 , more preferably 150 - 1000 g / m 2 , still more preferably 200 - 750 g / m 2 , particularly preferably 300 - 700 g / m 2 is. In the present invention, it is possible to form an interior material layer with high aesthetic properties with a relatively small coating amount, and it is also possible to achieve thinning and weight reduction of the film. 【0029】 Drying after painting the interior material may be carried out at normal temperature (preferably 0 - 50°C, more preferably 5 - 45°C), and heating can also be carried out as necessary. 【0030】 [[ID=一十九]] The interior material layer formed by such an interior material can exhibit a low gloss and a calm finish feeling. The specular glossiness (measurement angle 60 degrees) of the interior material layer is preferably 40 or less, more preferably 20 or less, still more preferably 10 or less. 【0031】 The interior material layer can be formed using one type or two or more types of interior materials. When using two or more types of interior materials of different colors, it is also possible to form an interior material layer rich in color with a mixture of multiple colors. 【0032】 In this invention, after painting the interior material, the surface of the interior material layer can be polished. The polishing treatment can be performed, for example, to improve the smoothness of the coating. The polishing treatment can be carried out by known methods using abrasive cloth or the like. The grit size of the abrasive cloth or the like can be appropriately selected according to the desired degree of smoothness. It is also possible to perform the treatment using two or more types of abrasive cloth or the like. Furthermore, during the polishing treatment, the surface of the coating can be moistened with water or the like as needed while polishing. The powder generated by polishing can be removed with an air blower or a cloth. 【0033】 [Transparent coating layer] In this invention, a transparent coating layer is laminated onto the surface of the interior material layer. The amount of the transparent coating layer applied is 0.1 to 30 g / m² in terms of solid content. 2 In this invention, by laminating such an interior material layer and a transparent coating layer, it is possible to obtain a coating that exhibits a low-gloss, subdued finish and also possesses scratch resistance. 【0034】 A transparent coating layer can be obtained by applying (painting) a transparent coating material containing a resin component. Examples of resin components in the transparent coating material include cellulose, polyvinyl alcohol, ethylene resin, vinyl acetate resin, polyester resin, alkyd resin, vinyl chloride resin, epoxy resin, acrylic resin, urethane resin, acrylic silicone resin, fluororesin, etc., or composites thereof. These can be used individually or in combination of two or more. Examples of resin component forms include water-soluble resins, water-dispersible resins (resin emulsions), solvent-soluble resins, solvent-free resins, non-water-dispersible resins, powder resins, etc. Among these, water-soluble resins and / or water-dispersible resins are preferred, and an embodiment containing a water-dispersible resin is particularly preferred. By using water-soluble resins and / or water-dispersible resins, an aqueous transparent coating material can be obtained. Furthermore, these resin components may be either crosslinking-reactive or non-crosslinking-reactive. 【0035】 The glass transition temperature of the resin component in the transparent coating material is preferably 20°C or higher, more preferably 25 to 80°C, and even more preferably 30 to 60°C. By including such a resin component in the transparent coating material, scratch resistance and other properties can be further enhanced. This glass transition temperature can be determined using Fox's formula. 【0036】 Acrylic resin emulsions are preferred as the resin component in transparent coating materials. Acrylic resin emulsions are aqueous dispersions of polymer particles mainly composed of alkyl (meth)acrylate esters. Such acrylic resin emulsions can be obtained, for example, by emulsion polymerization of a group of monomers including alkyl (meth)acrylate esters and, if necessary, other monomers, using known methods. 【0037】 Examples of alkyl (meth)acrylates include methyl (meth)acrylate, ethyl (meth)acrylate, isopropyl (meth)acrylate, n-butyl (meth)acrylate, isobutyl (meth)acrylate, t-butyl (meth)acrylate, n-amyl (meth)acrylate, isoamyl (meth)acrylate, n-hexyl (meth)acrylate, 2-ethylhexyl (meth)acrylate, octyl (meth)acrylate, decyl (meth)acrylate, dodecyl (meth)acrylate, octadecyl (meth)acrylate, cyclohexyl (meth)acrylate, phenyl (meth)acrylate, and benzyl (meth)acrylate. These can be used individually or in combination of two or more. The composition ratio of such alkyl (meth)acrylates is preferably 30% by weight or more, more preferably 40 to 99.9% by weight, and even more preferably 50 to 99.5% by weight, relative to the total monomers constituting the acrylic resin emulsion. In this invention, alkyl acrylates and alkyl methacrylates are collectively referred to as (meth)alkyl acrylates. 【0038】 Other monomers include, for example, carboxyl group-containing monomers, amino group-containing monomers, pyridine monomers, hydroxyl group-containing monomers, nitrile group-containing monomers, amide group-containing monomers, epoxy group-containing monomers, carbonyl group-containing monomers, alkoxysilyl group-containing monomers, aromatic monomers, sulfonic acid group-containing monomers, fluorine-containing monomers, polyoxyalkylene chain-containing monomers, divinyl monomers, trivinyl monomers, ultraviolet-absorbing group-containing monomers, and photostable group-containing monomers. These can be used individually or in combination of two or more. The proportion of these other monomers is preferably 0.1 to 60% by weight, more preferably 0.5 to 50% by weight, relative to the total monomers constituting the acrylic resin emulsion. 【0039】 As the acrylic resin emulsion, any that satisfies the above conditions can be used. For example, acrylic styrene resin emulsion, epoxy-modified acrylic resin emulsion, urethane-modified acrylic resin emulsion, silicone-modified acrylic resin emulsion, fluorine-modified acrylic resin emulsion, etc., can also be used. Furthermore, the form of the acrylic resin emulsion may be, for example, a multilayer structure emulsion (core-shell type emulsion) obtained by multi-step polymerization, or a crosslinking reaction type emulsion that undergoes a crosslinking reaction. 【0040】 The average particle size of the acrylic resin emulsion is preferably 30 to 200 nm, more preferably 50 to 160 nm. This average particle size is measured by dynamic light scattering (measurement temperature: 25°C). 【0041】 The ratio of resin components (solids) in the transparent coating material is preferably 1 to 50% by weight, more preferably 2 to 30% by weight, and even more preferably 3 to 15% by weight. 【0042】 The transparent coating material may also contain components other than those listed above, as long as they do not significantly impair the effects of the present invention. Examples of such components include coloring pigments, extender pigments, matting agents, thickeners, film-forming aids, leveling agents, wetting agents, plasticizers, antifreeze agents, pH adjusters, preservatives, antifungal agents, antialgal agents, antibacterial agents, dispersants, defoaming agents, adsorbents, fibers, water repellents, hydrophilic agents, crosslinking agents, coupling agents, ultraviolet absorbers, light stabilizers, antioxidants, catalysts, solvents, and water. The transparent coating material can be manufactured by uniformly mixing the above-mentioned resin components and, if necessary, each of the above components by conventional methods. 【0043】 The heat residue of the transparent coating material is preferably 1 to 50% by weight, more preferably 2 to 30% by weight, and even more preferably 3 to 15% by weight. This effectively suppresses unevenness caused by the coating of the transparent coating material, making it easier to obtain a uniform transparent coating layer. The heat residue referred to herein is the heat residue of the transparent coating material at the time of coating; if the transparent coating material is diluted before coating, the heat residue refers to the transparent coating material after dilution. The heat residue is measured according to the method of JIS K5601-1-2 "heat residue," under conditions of a heating temperature of 135°C and a heating time of 60 minutes. 【0044】 For painting the transparent coating material, tools such as sprayers, rollers, and brushes can be used. Drying after painting the transparent coating material can be done at room temperature (preferably 0 to 50°C, more preferably 5 to 45°C), and heating can be used if necessary. 【0045】 The amount of transparent coating to be applied is 0.1 to 30 g / m² in terms of solid content. 2 The amount is preferably 0.5 to 20 g / m². 2 Comfortable 1-10g / m 2This results in a low-gloss, subdued finish and improved scratch resistance. For interior material layers that have undergone polishing, it can also suppress whitening caused by polishing. Furthermore, if scratches occur due to polishing, these scratches can be repaired. If the amount of transparent coating applied falls below the lower limit, it will be difficult to obtain sufficient effects in terms of scratch resistance, etc. If the amount of transparent coating applied exceeds the upper limit, it will be difficult to obtain a low-gloss, subdued finish.

Interior material 1 was applied to this surface using a trowel, and then immediately spread and smoothed with the trowel to form the painted surface. The amount of interior material 1 applied (in terms of solid content) was 450 g / m². 2 After drying for 24 hours, the transparent coating material 1 was applied to the right half of the interior material coating at a rate of 6 g / m² (based on solid content). 2After roller painting, the surface was allowed to dry and cure for 7 days. Upon inspection of the appearance of the coating obtained by the above method, the right half (with the transparent coating layer) had a low gloss similar to the left half (without the transparent coating layer), and was a light gray coating with a flat, subdued finish. When the surface of the coating on the right half was rubbed with a cloth, no particular abnormalities were observed, indicating good scratch resistance. 【0053】 (Example 2) On a surface to be coated, similar to that in Example 1, the interior material 1 was applied with a trowel, and the coated surface was immediately spread and smoothed with the trowel. The amount of interior material 1 applied (in terms of solid content) was 450 g / m². 2 After drying for 24 hours, the surface of the interior material coating was lightly polished with abrasive paper. Next, transparent coating material 1 was applied to the right half of the interior material coating at a rate of 3 g / m² (based on solid content). 2 After roller painting, the surface was allowed to dry and cure for 7 days. Upon inspection of the appearance of the coating obtained by the above method, the right half (with transparent coating layer) had a low gloss similar to the left half (without transparent coating layer), and was a light gray coating with a flat, subdued finish. In addition, the left half was slightly whitened by polishing, but this whitening was eliminated on the right half. When the scratch resistance of the coating surface on the right half was checked using the same method as in Example 1, no particular abnormalities were observed and it was good. 【0054】 (Example 3) On a surface to be coated, similar to that in Example 1, interior material 1 and interior material 2 were applied with a trowel so that they were adjacent to each other and partially overlapping. The coated surface was then immediately spread and smoothed with a trowel. The amount of interior material 1 applied (in terms of solid content) was 250 g / m². 2 The application amount of interior material 2 (calculated in terms of solid content) is 200g / m². 2 After drying for 24 hours, the surface of the interior material coating was lightly polished with abrasive paper. Next, transparent coating material 1 was applied to the right half of the interior material coating at a rate of 2 g / m² (based on solid content). 2After roller painting, the surface was allowed to dry and cure for 7 days. Upon inspection of the appearance of the resulting coating, the right half (with the transparent coating layer) had a low gloss similar to the left half (without the transparent coating layer), and the coating had a flat, subdued finish. The resulting coating exhibited a mortar-like aesthetic with a mixture of light gray and dark gray areas, and visible variations in shade due to intermediate tones. In addition, the left half was slightly whitened by polishing, but this whitening was eliminated on the right half.

The amount of interior material 1 applied (in terms of solid content) was 450 g / m². 2 After drying for 24 hours, the surface of the interior material coating was lightly polished with abrasive paper. Next, transparent coating material 2 was applied to the right half of the interior material coating at a rate of 3 g / m² (based on solid content). 2 After roller painting, the surface was allowed to dry and cure for 7 days. Upon inspection of the appearance of the coating obtained by the above method, the right half (with transparent coating layer) had a low gloss similar to the left half (without transparent coating layer), and was a light gray coating with a flat, subdued finish. In addition, the left half was slightly whitened by polishing, but this whitening was eliminated on the right half. When the scratch resistance of the coating surface on the right half was checked using the same method as in Example 1, no particular abnormalities were observed and it was good. 【0056】 (Comparative Example 1) On a surface to be coated, similar to that in Example 1, the interior material 1 was applied with a trowel, and the coated surface was immediately spread and smoothed with the trowel. The amount of interior material 1 applied (in terms of solid content) was 450 g / m². 2 After drying for 24 hours, the transparent coating material 1 was applied to the right half of the interior coating at a rate (in terms of solid content) of 0.05 g / m². 2After roller painting, the surface was allowed to dry and cure for 7 days. Upon inspection of the appearance of the film obtained by the above method, the right half (with transparent coating layer) had a low gloss similar to the left half (without transparent coating layer), and a flat, subdued finish of light gray film was obtained. However, when the scratch resistance of the film surface on the right half was checked using the same method as in Example 1, some scratches occurred. 【0057】 (Comparative Example 2) On a surface to be coated, similar to that in Example 1, the interior material 1 was applied with a trowel, and the coated surface was immediately spread and smoothed with the trowel. The amount of interior material 1 applied (in terms of solid content) was 450 g / m². 2 After drying for 24 hours, transparent coating material 1 was applied to the right half of the interior coating at a rate of 50 g / m² (based on solid content). 2 After roller painting, the surface was allowed to dry and cure for 7 days. Upon examining the appearance of the coating obtained using the above method, the right half (with the transparent coating layer) exhibited a glossier finish compared to the left half (without the transparent coating layer), resulting in a different finish compared to the coating of interior material 1.
