Contents However, the technical orders described in Patent Documents 4 to 6 use the reflection interference light from ', so the flickering feeling due to the scattering of light is accompanied by, and it is not suitable for creating a calm atmosphere brought about by the black. Further, in the decorative material of Patent Document 6, although it is described that a black background layer can be used, the dressing material is formed of a metal thin film to form a light reflecting layer, and thus a black metallic color is obtained. Further, in the technique described in Patent Document 7, since it is a decorative sheet, 4 200944394 * It is necessary to ensure transparency, and there is a problem that discomfort occurs when using black paint. The present inventors conducted intensive studies in order to obtain a clear pattern with a high-grade lacquer black background. The new conclusion is that the reason why the lacquer black which is more advanced is not obtained is that the light is not absorbed by the black layer and is reflected. Therefore, it has been found that in the incident light, by using both the reflected light and the absorbed light, it is possible to obtain a vivid color pattern having a high-grade black lacquer as a background color. The present invention provides a decorative material comprising: a transparent substrate having fine concave projections thereon; a colored transparent layer formed on the transparent substrate; and a black layer formed on the colored transparent layer. Its structural feature is that in the dark background color, a color pattern appears at a position corresponding to the above-mentioned fine concave convex portion. In this decorative material, fine uneven portions are formed between the transparent substrate and the color transparent layer. Therefore, some of the light incident on the decorative material from the side of the transparent substrate is reflected in the fine concave portion, and a sharp pattern is obtained at the position _ corresponding to the fine uneven portion. In addition, since the black layer absorbs light, it is possible to obtain a dark enamel which exhibits a high-grade feeling. For this reason, it is possible to obtain an aesthetic feeling that has not been obtained in the past, and to obtain a decorative material having a clear color pattern in a background color having a black sensation. According to the present invention, it is possible to achieve a decorative material and an ornament which obtain a vivid color pattern in a background color having a black sensation. [Embodiment] Hereinafter, the best embodiment of the decorative material of the present invention will be described in detail with reference to the accompanying drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and the repeated description is omitted.

However, the county has a convenient provision for the purpose of simply explaining the relative relationship of the constituent elements, and is not limited to the direction in which the product embodying the present invention is manufactured and used. In the embodiment, the arithmetic mean roughness Ra is calculated according to the method specified in Japanese Industrial Standard B060 1 and is defined as follows: "No" means that the reference length is selected from the roughness curve along the direction of the average line. The direction is U, and the direction of the vertical magnification is taken as the Y-axis. When W (1) is used to indicate the thick line, as shown in Figure i. No, the value obtained by the following formula is expressed in microns (V m), R 〇 = ]i\f (x^ /: basic length The maximum height (Ry) is defined as follows:

Ry means that the basis length is selected from the roughness curve along the direction of the tenth mean line of the flat angle, and the interval between the peak line and the bottom line of the selected portion is measured in the longitudinal magnification direction of the roughness curve. Expressed in micrometers Um), refer to Figure 1

Ry = Rp + Rv . Note: Ry is taken as a part of the scratch without any mountains and troughs, only used as the base length. BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 is a cross-sectional view showing the principle of light incident on a decorative material of the present invention. The decorative material 100 includes a transparent substrate 10 having a fine surface 200944394 on the back surface (under τ旳 in FIG. 1) • a concave-convex portion 4〇, and a color transparent layer 20 formed under the transparent substrate ι, and a transparent layer in color 2〇 The black layer 30 formed below. In the case of the decorative base material 1 having the above configuration, when the transparent substrate 10 is viewed from above, a colored pattern appears in a position corresponding to the fine uneven portion 4 in the dark background color. The surface of the transparent substrate 10 (the lower surface in Fig. 1) may form the fine uneven portion 40 over the entire surface, or may be formed only on a portion. According to the formation region of the fine uneven portion 40, the change in the pattern can be increased, and in addition, the aesthetic effect produced by the comparison with the background color can be obtained. Further, by forming only a part of the fine uneven portion 40, the pattern region can be defined to represent a pattern, a font, a binding, and the like. The lower limit of the thickness of the transparent substrate 10 is not particularly limited, but is preferably 0.05 mm or more, and more preferably 0 lmin or more. Further, the upper limit of the thickness of the transparent substrate 10 is not particularly limited, but is preferably i 〇 mm or less, and more preferably 3 mm or less.透明 Transparent substrate 1 〇 At least one of a transparent resin plate, a glass plate, and a transparent ceramic plate can be used. Further, the transparent substrate 10 may be a single layer or a plurality of layers, and may also contain a film. In addition, the transparent substrate 10 may be colorless or colored. Thus, patterns of various hues can be obtained. The fine uneven portion 40 is a concave portion or a convex portion, and includes any form of a concave portion or a convex portion for the surface of the transparent substrate 10. The fine four-convex portion 40 further includes grooves, holes, or holes obtained by roughening the surface of the transparent substrate 1〇. Further, the fine uneven portion 4〇 is preferably at least one of a matte shape, a 200944394•fine line shape, a groove shape, a granular protrusion shape, and a diffraction grating shape. Further, the fine uneven portion 4 can be formed of an ultraviolet curable resin. Thus, the uneven shape of the desired shape or size can be obtained, and the pattern pattern having various functions can be easily achieved. The fine concavo-convex portion 40 serves as a pattern region (a region in which fine concavities and convexities are provided), and a flat or three-dimensional pattern is formed on the upper surface of the decorative material 1 (the lower surface of the transparent substrate 1 in Fig. i). The fine concavo-convex portion 4〇 can reflect a part of the light incident from the side of the transparent substrate 1 and pass through the other portion. In addition, the action of the scatterer that scatters light can be exerted. The shape of the fine uneven portion 40 is not particularly limited, and is, for example, an example shown in Fig. 8. Fig. 8 is an enlarged cross-sectional view showing a cross section of the fine uneven portion 4A. As shown in Fig. 8 (a), the fine uneven portion 4 is formed to be concave or convex almost in parallel in the normal direction of the surface of the transparent substrate. The arithmetic mean roughness "(jIS b〇6〇i) of the fine uneven portion 40 is preferably 0.05/zm or more, and more preferably 〇 or more. Further, Ra ❿ is preferably the following, more preferably the following. In other words, the scattering ability of the fine uneven portion 4 〇 (scatterer) in this range depends on the shape and the refractive index difference from the surrounding, but the scattering energy for visible light described in the Mie scattering t is usually 2 The range of ～3 has a larger scattering ability than the scattering ability 2 when the scatterer is large, so that a larger amount of reflected light can be obtained. The distance between the respective unevenness of the minute uneven portion is preferably the degree of arithmetic mean roughness Ra. Therefore, the amount of reflected light is also extremely large. In other words, the amount of reflected light of the fine uneven portion 40 (scattering body) existing in the plane and the scattering ability of each fine 8 200944394 micro uneven portion 40 (scattering body) and the fine unevenness per unit area 40 (the scatterer) is related to the number of the scatterers. Of course, the larger the amount of the scatterers, the larger the amount of reflected light. For this reason, it is preferable to distribute the average size of the fine uneven portions 40 (scatterers). The scatterer density is the largest, and the amount of reflected light is also extremely large.

In addition, in the relationship with the arithmetic mean roughness, for example, when Ra is 1 # m and the fine uneven portion 40 (scatterer) is filled with a fine potential, the fine uneven portion 40 having a similar shape is compared with when Ra is 3 "/ (scatterer), the number of which can be 9 times. For this reason, the product of the scattering power can be compared, and when Ra is 1/IM, the amount of reflected light may become large. Further, as shown in Fig. 8 (b), the fine uneven portion 4 〇 may have a first region 401 formed as a large concave portion having a depth of 5 " m or more and a second region 402 having no large concave portion formed. The arithmetic mean roughness Ra (JIS B 〇 6 〇 1) of the fine uneven portion 40 in the second region 402 in the case of the reverse seeding is preferably 〇 〇 5 " m or more, and more preferably 〇. l / zm or more. Further, Ra is preferably 5 " m or less, more preferably the following. The large concave portion 41 is larger than the concave portion of the fine uneven portion 4A, and the large concave portion 41 is 5 inches or more and 50 or less. Further, the opening width of the large concave portion 41 is not particularly limited, but is preferably the above. Further, the inner surface of the large concave portion 41 may be further provided with minute uneven portions 4 (Fig. 1, ;, , , , , , , , , , , , , , , , , , , , , , , , , , Since the normal direction of the surface is different, the reflection direction of the incident light from the same-student direction is different from that of the surface reflection, and the different directions can be seen from different directions. The inner wall surface of the recessed portion 41 is a sloped surface, and the normal direction of the sloped surface can be different from the normal direction of the unevenness forming region of the figure $ region provided in the smooth surface or the smooth surface other than the pattern region. In the direction of reflection, the direction in which the pattern can be viewed is controlled. Further, the directivity of the reflected light from the fine uneven portion 4 (pattern region) is controlled by combining the directivity or angle of the inner wall surface of the large concave portion 41 of the fine uneven portion 4 A plurality of patterns can be visually recognized from a specific direction. Further, by defining a minute uneven area as a pattern area, the fine uneven portion 40 and the large concave portion 41 can be expressed. When the large concave portions 41 are formed cyclically, the average interval (pitch) is not particularly limited, and can be arbitrarily set. The average interval (pitch) of the large concave portions 41 can be observed with an electron microscope. The surface shape of the large concave portion 41 is calculated by calculating the average period of the large concave portion 41. The pitch of the large concave portion 41 is preferably m or more and 50 or less, more preferably 2 〇 / / m or less. A method of rough surface processing can be used, and it is particularly preferable to form by at least one of matte pattern processing, fine line pattern processing, groove pattern processing, granular pattern convex processing, and diffraction grating pattern processing. The reflection-enhancing structure of the uneven portion 4 。. By combining the processing directions of these methods, a structure in which minute fine uneven portions 40 are distributed in the interface between the color transparent layer and the transparent substrate can be obtained. 10 200944394 Furthermore, By making the minute fine concavo-convex portions 4〇 linear, the distribution has a direction of reflection, surface reflection, and reflection of the surface reflection. The direction of reflection can be strongly reflected in the plane perpendicular to the direction of the line group.

The lower limit of the text is preferably 丨", and the color tone of the color transparent layer 20 has no color tone and fine unevenness of the bright layer 20 (4). The pattern of colors. The combination of the shapes can be regarded as a material of the black layer 30, such as a vinyl resin, a gas-based resin of a gas-ethylene-cerium acetate as a resin binder, a polycarbonate resin ester copolymer resin, an acrylate acrylonitrile-butyl Diuretic-phenylethylene-based tree;: Poly: resin, polypropylene wax, and color method are not particularly limited to polyacrylonitrile-based resins.

Play as a light absorbing layer 200944394 The effect of the decorative material 1 下面 will be described below. In the decorative material 100, fine uneven portions 4 are formed on the interface between the transparent substrate 10 and the color transparent layer 20. Therefore, a part of the light which is incident on the decorative material 1〇〇 from the side of the transparent substrate 1 is reflected by the fine uneven portion 4〇, and a sharp pattern is obtained at the position corresponding to the fine uneven portion 40. In addition, the black layer 30 absorbs light, whereby a black lacquer having a deep sensation and a high-grade feeling can be obtained. As a result, the aesthetic feeling that has not been obtained in the past is obtained, and the decorative material 100 which obtains a vivid color pattern in the background color having a black sensation is obtained. This will be described in further detail with reference to Figs. Fig. 1 is a cross-sectional view showing the principle when light is incident on the decorative material of the present embodiment. Fig. 9 is a cross-sectional view showing the principle when light is incident on a laminate of a conventional transparent substrate and a color transparent layer. As shown in FIG. 9, the white light L1 incident on the upper surface of the transparent substrate 1 of the laminated body 300 is transmitted through the transparent substrate 1 and is divided into the transmitted light L2 passing through the color transparent layer 20 and the colored transparent layer 20. The surface reflected light of a small amount of reflection ❹ and the surface reflected light L3(o) or the absorbed light L4 absorbed into the color transparent layer 20 are differently incident on the opposite side of the colored transparent layer 20 [5 also Similarly to the white light L1, after passing through the color transparent layer 20, it is divided into the transmitted light L6 that has passed through the transparent substrate 10, the surface reflected light that is slightly reflected on the lower surface of the transparent substrate 1〇, and the surface reflected light (not shown), or Several kinds of absorbed light (not shown) are absorbed into the transparent substrate 10. • In other words, when the laminated body 300 is viewed from the upper surface of the transparent substrate 10, the color of the transparent layer 12 200944394 layer 20 is formed by the transmitted light L2, the reflected light L3 (〇), and the transmitted light L6, and is recognized as heat. The light energy of the reflected light L3 (〇) is about 1%', which is very small compared to the transmitted light L2, the read A4·, and the transmitted light L 6 , and the wavelength region is different from the transmitted light L2 and the transmitted apricot Tc. It is also often difficult to see. Therefore, the transmitted light L2, & τ transmits the first L6 as the main color to be recognized. For this decorative material, the cross-sectional structure of the decorative material is as shown in Fig.

Configuration. The decorative material 1〇〇 is composed as follows: in the transparent substrate W

Of the incident light incident on the upper surface and through the transparent 1fW coffin 10, a part of the incident light is reflected by the fine concavo-convex portion 40, and is directed to the outside of the 逐 逐 逐 monthly substrate, while another portion passes through the color transparent layer 20 to A aa ^ is transported to the black layer 30. The details are as follows. The 7F 'decorative material 1'' as shown in Fig. 1 is provided with a black layer 30 under the color transparent 胄2〇, and a fine uneven portion 40 is formed on a part of the upper surface of the color transparent layer 2〇. The white light u incident on the upper surface of the transparent substrate 1 passes through the transparent substrate 10 and is divided into the absorption light L7 which is transmitted through the color transparent layer 2〇 and absorbed by the black layer 30, and the surface which is slightly reflected on the upper surface of the color transparent layer 2〇. The reflected light and the surface reflected light L3 (〇), the reflected light L3 (eo) reflected in the fine uneven portion 4〇, or the absorbed light L4 absorbed into the colored transparent layer 2〇 are several types. In this case, the transmitted light L2 shown in Fig. 9 = the absorbed light L7. On the other hand, the illumination light 15 incident on the lower side of the black layer 30 is no longer present because it is absorbed by the black layer 30. Here, the fine uneven portion 40 is formed in a part of the upper surface of the color transparent layer 20. The amount of reflected light of the reflected light L3 (eo) reflected by the fine uneven portion 40 can be made remarkable by the fine uneven portion 40 than the reflected light L3 (〇) 13 200944394

Enhance so that the reflected light L3 ( eo ) with enhanced light amount can be recognized. For this reason, when the decorative material is viewed from the upper surface of the transparent substrate 10, part of the incident light (white light) L1 is reflected by the fine uneven portion 4 into the reflected light L3 (eo), and the fine uneven portion 4〇 can be clearly seen. On the other hand, the reflected light L3 ( 〇 ) is almost unrecognized, and the black with black feeling is regarded as the substrate of the pattern. In this way, it is possible to achieve a decorative material that is aesthetically pleasing, has a background color that is dark, and is considered to have a vivid three-dimensional effect. Next, a method of manufacturing the decorative material 100 in the present embodiment will be described.衣衣何科" U 衣 〇 first 'prepare the above flat transparent substrate 10, forming fine irregularities on the transparent substrate. Next, apply a transparent transparent ink or coating on the transparent substrate to form a colored transparent layer 20 Then, a color ink or a coating material is applied, and a black layer 30 is sequentially formed and manufactured. The method of forming the fine uneven portion 40 may be a rough surface processing method, and particularly, a matte pattern processing, a fine line pattern processing, and a granular pattern projection processing are particularly preferable. In the case of diffraction grating pattern processing, at least, it is possible to obtain a surface with a decorative material, for example, because a dark-colored pattern with a black background can be obtained for the recent demand for a surface mount (four) high. The telephone solid can be used for the high-end painting of the LCD TV frame, etc. It is also used by the ^ person t. In addition, it is also used for the painting of the car, special wallpapers, etc., and can also be « 14 200944394 'with a sense of quality The decorative material for interior decoration is used. The decorative material of the present invention and the manufacturing method thereof are not limited to the above embodiments, and various modifications are possible. * In the above embodiment, an example in which the large recess 41 is formed in the first region 401 is exemplified, and in the first region 4〇1, a large convexity of 5 " The large convex portion is larger than the convex portion of the fine uneven portion 40, and preferably has a maximum width of 1" or more. Further, fine uneven portions 40 may be provided on the outer wall surface of the large convex portion. The same effect as that of the above-described large concave portion 41 can be obtained by such a large convex portion. In the first region 401, either or both of the large concave portion 41 and the large convex portion can be formed. The invention will be described in detail below by way of examples of the invention. [Experiment 1] The following experiment was carried out using Example 1. (Example 1) 图案 A pattern (concave-convex portion) was formed by thin-line processing on a transparent substrate using polycarbonate, and a blue color transparent layer (KKY 44 〇 blue manufactured by SEIKO ADVANCE Co., Ltd.) was sequentially laminated by screen printing. And black layer (SEU0ADVANCE Co., Ltd. ΚΚΥ 710 black) coating film. The pattern was obtained by coating a thin wire shape with a UV curable resin and setting it on a transparent substrate to obtain a decorative material 1. Appearance when the decorative material obtained from the side of the transparent substrate is irradiated with light * The image is shown in Fig. 2 . In Fig. 2, in the dark background color, a speckled pattern (purple red) represented by white-color appears, which can be stereoscopically recognized. 15 200944394 Next, the state of the fine unevenness formed on the surface of the transparent substrate of the decorative material 1 was measured. The surface shape of the decorative material 1 was observed using a laser microscope VK-9500 manufactured by KEYENCE Co., Ltd. As a result, the average interval of the large concave portions formed by the periodic cycle was calculated to be approximately 50 μία pitch. In addition, the "maximum height Ry" in the "reference length" 250//Π1 of the fine unevenness corresponding to the position of the visible pattern is ~uem, and the "arithmetic average height Ra" is ～0.3 μm (see Example 1). The company's SEIKO ADVANCE system produces a 440 blue colored color transparent layer and measures the spectral transmittance distribution (the spectral distribution of L2). In this case, the spectrum to be measured corresponds to the spectrum of L2 shown in Fig. 9 . The result is shown in FIG. As shown in Fig. 3, the spectrum has a peak at 490 nm (transmission 50%), and the FWHM (full width at half width) centered at 49 nm is about 20 nm. As is apparent from Fig. 3, the light incident on the color transparent layer was transmitted through the FWHM 120 nm region (370 nm to 610 nm) centered at 490 nm, and hardly transmitted through the region from 580 nm to 740 nm. The peak of the transmittance is about 50%, which is a transparent hue. (Reference Example 2) The spectral reflectance distribution (spectral distribution of L6) of a two-layered body of a color transparent layer colored with KKY 440 blue manufactured by SEIKO ADVANCE Co., Ltd. and a white reflecting plate was measured. In this case, the spectrum to be measured corresponds to the spectrum of L6 shown in Fig. 9. In this measurement, L2 and L5 of Fig. 1 are almost equivalent to the same case, and are reciprocally transmitted. 16 200944394 The result is shown in FIG. As shown in Fig. 4, the spectrum has a peak at 470 nm (reflection is 53%, and the reflectance from the white reflector is set to 100%), and the FWHM centered at 47 〇 nm is about 90 nm. Further, from 560 nm, there are a certain amount of reflected light on the long wavelength side, and there is a gentle peak near 620 nm and 720 nm, and the reflectance increases after 740 nm. We see that, unlike the case of Fig. 3, the full width of the half width is substantially reduced to 90 ιηη, and the reflected light is emitted from the 560 nm on the long wavelength side. Further, such a reflected light amount corresponds to L3 (〇) in Fig. 9, and a small amount of surface reflection and surface reflection occur on the upper surface of the color transparent layer. (Reference Example 3) The spectral reflectance distribution (L3 (〇) or L3 (eo) spectral distribution) of a two-layered body of a color transparent layer and a black layer colored with KKY 440 blue manufactured by SEIKO ADVANCE Co., Ltd. was measured. The spectrum measured in this case corresponds to the spectrum of L3 (〇) or L3 (eo) shown in Fig. 1 . In the Φ measurement, as explained with reference to Fig. 1, incident light from the back surface (lower surface) of the black layer was completely absent. The result is shown in FIG. As shown in Figure 5, the reflectance is around 1%. Further, in the vicinity of 420 nm, around 620 nm, around 720 nm, and after 740 nm, there is a peak having a relatively large reflectance. The peak near 420 nm occupies the blue region of the main wavelength region. The result of the synthesis of the peak light of these four points is purple. This is the same color as the speckled pattern represented by white in Fig. 2. 17 200944394 As shown in Fig. 3 to 5, the transmitted light of the color transparent layer is absorbed in the black layer, so that the background color of the black color can be visually recognized, and the surface reflection on the color transparent layer can be visually recognized, and the surface reflection can be enhanced in the fine uneven portion. The distinctive pattern is presented, and a decorative material suitable for achieving a high-grade decoration is obtained. [Experiment 2] The following experiment was carried out using Example 2 shown below. (Example 2) Φ

A color transparent layer colored with a dark blue transparent ink (VIC concentrated 400 dark blue manufactured by SEIK0 ADVANCE) was used instead of the blue colored transparent layer used in the above Example 1, and the same coating film lamination as in Example 1 was carried out. . Further, Fig. 6 is formed by using a UV-curable resin to form a straight line processed state (fine uneven portion), and is placed on a transparent substrate to obtain a decorative material. The spectral reflectance distribution (L3 ( 〇) 戋 L3 (eo) spectral distribution) of the obtained decorative material (hereinafter referred to as "black blaze light") was measured. In this case, the measured spectrum corresponds to the spectrum of L3 (〇) or T, y 4 W C eo) shown in Fig. 1 and the result is shown in Fig. 6 as "black blaze". (Reference Example 4) The spectral transmittance of a two-layered body of a color transparent and transparent substrate coated with a dark blue transparent ink (VIC concentrated 400 dark blue by sEU〇ADVANCE Co., Ltd.) was measured as 6 ru nr. The spectral distribution of & ,, (hereinafter referred to as "transmitted light") and the spectral reflection of the dry knife K L6 spectral name 18 200944394 cloth) (x is called reflected light)). In this case, the measured spectrum is equivalent to the spectra of L2 and L6 shown in Fig. 9. The result is shown in FIG. 6. As shown in FIG. 6, the transmitted light has almost no light amount at a wavelength other than the wavelength region in which the main hue is displayed, but since the color is deep, even at the peak, the transmittance is 1 as indicated by the vertical axis on the left side. %about. For example, the vertical axis of the left side does not reflect the reflectance of the light outside the main wavelength region by about 1%. This is the surface reflection of the colored transparent layer and the beta reflection of the surface reflection. As shown in Fig. 6, as shown by the vertical axis on the right side, the spectral distribution of the black blaze light is an extremely low reflectance (%), but has the same peak as the spectrum of the reflected light of the color transparent layer. From the above, it is known that since the surface reflection of the color transparent layer and the reflected light of the surface layer reflection are enhanced, the color of the recognized pattern area can be regarded as a purple color, which is a blue color near 48 Onm and a very dark tone ❹ red color of 730 nm or more. Center, mixed with orange near 580 nm and orange with overlapping red near 660 nm. From the measured values shown in Fig. 6, the spectral spectra of L3 ( 〇 ) and L3 (eo ) were obtained by a calculation formula. The result is shown in FIG. The transmittance distribution in Fig. 6 is the spectroscopic spectrum of the transmitted light L2 in Fig. 9, and is given by the following formula (1). Transmittance distribution of transmitted light L2 = wavelength distribution of incident light L1 X. Transmittance distribution of bright substrate X Transmittance distribution of colored transparent layer... (1) 19 200944394 Similarly, the reflection in Fig. 6 The rate distribution is measured by providing a white reflecting plate behind the color transparent layer in Fig. 9, and is given by the following formula (2). Reflectance distribution of Fig. 6 = reflectance of reflected light L3 (〇) of color transparent layer ^ transmittance distribution of transmitted light L6 = reflectance distribution of reflected light L3 (o) of color transparent layer + transmitted light L2 Transmittance Distribution X Reflectance Distribution of White Reflector x Transmittance Distribution of Transmitted Light L2...(2)

From the above formulas (1) and (2), the spectral spectra of the reflected light L3 (〇) and L3 (eo) shown in Fig. 1 are given by the following formula (3). Reflectance distribution of reflected light L3 (eo) == reflectance distribution of Fig. 6 - transmittance distribution of transmitted light L6 = reflectance distribution of Fig. 6 - transmittance distribution of transmitted light L2 X reflectance distribution of white reflecting plate Transmitted light.
