Description

[Technical field]

[0001] The present invention relates to a building board and a pattern for decorating the surface of a substrate. [Background technology]

[0002] Technologies related to building boards have been proposed. For example, Patent Document 1 discloses a building board. The building board is an exterior material. The building board is formed by arranging a plurality of rectangular convex portions adjacent to each other vertically and horizontally. The convex portions have slopes. The slopes slope downward toward a pair of opposing ends. At least one of the slopes is provided with a shadow-forming structure. The shadow-forming structure is a protrusion. The protrusion is a rib-shaped protrusion. The rib-shaped protrusion is provided in a direction approximately perpendicular to the inclination direction of the slope. The density of the protrusions increases from the center side of the protrusions toward the end side. The protrusion height increases from the center side of the protrusions toward the end side. The building board can sufficiently emphasize the three-dimensional effect.

[0003] Patent Document 2 discloses an inkjet print. The inkjet print is an interior material or wallpaper for a vehicle or building. The inkjet print includes a substrate and a plurality of ink dots. The substrate has moisture absorbing and releasing properties. The ink dots form a pattern expressed on the surface of the substrate, and are formed in a partial area of ​​the substrate surface. The pattern expressed on the substrate surface by the ink dots includes a gradation in which the lightness changes continuously. The gradation is a L * a * b * Lightness L in color system * The difference in brightness between the maximum and minimum values ​​of ΔL * is set in the range of 8 to 12.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0014] The embodiments for carrying out the present invention will be described with reference to the drawings. The present invention is not limited to the configurations described below, and various configurations can be adopted within the same technical concept. For example, some of the configurations shown below may be omitted or replaced with other configurations. The present invention may include other configurations. The drawings show a specific configuration in a schematic manner.

[0015] <Architectural board 200> Regarding the building board 200, FIG. ~5 The construction board 200 will be described with reference to FIG. For example, the construction board 200 can be used as an exterior material, an interior material, and a decorative board for an entrance door. An example of an exterior material is siding. For example, the interior material is used for humidity-regulating building materials, wall materials, and interior doors. The construction board 200 includes a base material 210 and a pattern 220 (see FIGS. 1 and 2). The construction board 200 is installed on a building with the surface including the pattern 220 as the front side. A person viewing the construction board 200 visually recognizes the pattern 220 provided on the surface of the base material 210 when the construction board 200 is installed on a building. In the embodiment, the surface of the base material 210 means the surface on which the pattern 220 is provided among the multiple surfaces forming the plate-shaped base material 210. In this case, the surface of the base material 210 becomes the front surface (front side surface) of the base material 210, and becomes the surface (front surface, front side surface) of the construction board 200 when the pattern 220 is provided.

[0016] Examples of the substrate 210 include a ceramic plate, a metal plate, a resin plate, a glass plate, and a wooden plate. The wooden plate includes a wood board. For example, when the building board 200 is a siding, the substrate 210 may be a ceramic plate, a metal plate, or a resin plate. However, the substrate 210 may be a plate material of a different material from the above. In addition, the substrate 210 may be a laminated plate of two or more layers including plate materials of different materials or the same material, or may be a plate material made of a composite material of two or more materials. The material of the plate material to be the substrate 210 is appropriately determined in consideration of various conditions. For example, this material is appropriately determined according to the application or specifications of the building board 200. The surface of the substrate 210 may be primed in the same manner as the substrate of a known building board. The building board 200 employs a substrate similar to that of a known building board as the substrate 210. When the surface of the substrate 210 is primed, a known substrate treatment is adopted. Therefore, other explanations regarding the substrate 210 will be omitted.

[0017] The pattern 220 decorates the surface of the substrate 210. The surface of the substrate 210 has a planar shape, and the pattern 220 is formed two-dimensionally on the surface of the substrate 210 (see FIG. 3). An example of a method for forming the pattern 220 is printing. When the pattern 220 is printed on the surface of the substrate 210, the pattern 220 is a two-dimensional printed pattern. Examples of printing include screen printing, gravure printing, and inkjet printing. The pattern 220 is provided on the entire surface of the substrate 210 (see FIGS. 1 and 2). However, the area on which the pattern 220 is provided may be a part of the surface of the substrate 210. The building board 200 may include a clear layer that covers the pattern 220 on the surface. This clear layer protects the pattern 220. Building boards having a clear layer on the surface are known. Therefore, further explanation of the clear layer is omitted.

[0018] Pattern 220 includes a plurality of pattern portions. Any one pattern portion of pattern 220 is in contact with one or more other pattern portions. Pattern 220 includes the plurality of pattern portions, which are pattern portions A, B, C, and D, and pattern portions E, F, G, and H (see FIGS. 2, 4, and 5).

The high-brightness region A5 is provided apart from the boundary regions A1, A2, and A3 within the separate region A4. The separate region A4 is opposite the boundary region B1 of the pattern portion B in the boundary region A1.

That is, the pattern portion E includes the high-brightness region E5 in the separate region E4. The high-brightness region E5 is provided apart from the boundary regions E1, E2, and E3 within the separate region E4. The separate region E4 is opposite the boundary region F1 of the pattern portion F in the boundary region E1.

The multiple pattern portions are each colored differently. The color of the pattern 220 including the multiple pattern portions is determined by the following formula: * a * b * L in color space * Value, a * value and b * It is specified by the value. * a* b * The color system is a method of displaying colors that was standardized by the International Commission on Illumination (CIE1976) and is also specified in JIS (JIS Z 8781-4). * The value is called the lightness index. * Regarding the relationship between the value and the brightness, the higher the brightness, the * The value is larger.
