- the second interference pigment 24 is composed of a thin flake (not shown) that is transparent to visible light, and a metal oxide film (not shown) that covers the flake. Light that is reflected on the surface of the metal oxide film out of the light incident on the second color pattern layer 20 from the translucent substrate 4 side interferes with light that passes through the metal oxide film and is reflected on the surface of the flake, generating interference light. By adjusting the film thickness and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

- the transparent smoke printed layer 30 is provided on the second color pattern layer 20 as shown in FIG. 1.
- the transparent smoke printed layer 30 can be provided on the second color pattern layer 20 by, for example, screen printing, inkjet printing, gravure printing, or offset printing using an ink in which a small amount of carbon black is dispersed in a resin binder such as a vinyl-based, acrylic-based, urethane-based, or polyester-based resin binder.
- the thickness of the transparent smoke printed layer 30 is, for example, 1 ⁇ m to 10 ⁇ m.
- the transparent smoke printed layer 30 may contain a hardener. In this case, the heat resistance of the transparent smoke printed layer 30 and the adhesion of the transparent smoke printed layer 30 to the second color pattern layer 20 can be improved.
- the transparent smoke print layer 30 may also contain a weathering agent. Known ultraviolet absorbing agents and light stabilizers can be used as weathering agents.
- the pattern is expressed by additively mixing the first interference light 15a, 15b generated by the first interference pigments 14a, 14b and the second interference light 25 generated by the second interference pigment 24.
- the total light transmittance of the printed matter 2 is, for example, 30% to 70%.
- the total light transmittance here refers to the value measured using a spectrophotometer (for example, the UV-2100 spectrophotometer manufactured by Shimadzu Corporation).
- the first color pattern layer 10 contains the first interference pigments 14a, 14b, and the second color pattern layer 20 contains the second interference pigment 24, so that a three-dimensional pattern can be realized even with a small number of printed layers.
- the first color pattern layer 10 is the only pattern layer of the first color pattern layer 10 and the second color pattern layer 20 that contains an interference pigment that generates different interference light, so that color matching and registration work during printing can be simplified. Therefore, with the printed matter 2, a three-dimensional pattern can be expressed even with a small number of printed layers, and color matching and registration work during printing can be simplified.
- the printed matter 2 includes a transparent smoke print layer 30 provided on the second color pattern layer 20. This provides better color development between the first color pattern layer 10 and the second color pattern layer 20. Furthermore, because the transparent smoke print layer 30 is transparent, the decrease in visibility of the image on the display device 1 is effectively suppressed.
- each of the first interference pigments 14a, 14b and the second interference pigment 24 contains titanium dioxide-coated mica with a particle size of 25 ⁇ m or more and 60 ⁇ m or less.
- titanium dioxide-coated mica with a particle size of 25 ⁇ m or more is contained, the transparency and color development of the picture-printed layer 5 can be improved.

- the content of the multiple second color pigment chips 23 is in the range of 0.5 parts by weight or more and 20 parts by weight or less when the second color binder is 100 parts by weight. Since the content of the multiple first color pigment chips 13 is in the range of 0.5 parts by weight or more, the pattern of the first color pattern layer 10 is well expressed. Since the content of the multiple first color pigment chips 13 is in the range of 20 parts by weight or less, a decrease in the coating properties and permeability of the first color pattern layer 10 can be suppressed.
- the content of the multiple second color pigment chips 23 is within the range of 0.5 parts by weight to 20 parts by weight, assuming that the second color binder 22 is 100 parts by weight, so that the pattern of the second color pattern layer 20 is well expressed while preventing a decrease in the coating properties and transparency of the second color pattern layer 20.
- the total light transmittance of the printed matter 2 is 30% to 70%. If the total light transmittance is 30% or more, when the printed matter 2 is placed in front of a screen, the light of the image on the screen makes it difficult to see the picture printed layer 5, and the image is more clearly visible. If the total light transmittance is 70% or less, the picture on the picture printed layer 5 is prevented from appearing dark even if the screen is black.
- the display device 1 includes a printed matter 2 and a light source 3. With the display device 1, when the light source 3 is not lit, the pattern on the pattern printing layer 5 is visible, and when the light source 3 is lit, the transmitted light from the light source 3 (pattern display, image display, etc.) is visible.
- the light source 3 may be a display device.
- the pattern on the pattern printing layer 5 is visible, and when the display is turned on, the transmitted light from the display (pattern display, image display, etc.) is visible.
- the multiple interference pigments 14a, 14b, 24 may contain pearl pigments.
- the picture printed layer 5 may contain multiple interference pearl pigments (interference pigments 14a, 14b, 24) that are different from each other.

The light reflected by the surface of the metal oxide film out of the light incident on the first color pattern layer 10 from the translucent substrate 4 side interferes with the light that passes through the metal oxide film and is reflected by the surface of the flakes, generating interference light. By adjusting the thickness of the metal oxide film and the refractive index of the metal oxide film, interference light having a desired wavelength can be generated.

- a printing method such as screen printing, inkjet printing, gravure printing, or offset printing may be used.
- the color of the smoke panel 63 is not limited, as various colors can be used and the panel may be the color of the wall of your choice.
- the smoke panel 63 may control the color tone of the light-transmitting decorative film 62 depending on the color of the smoke panel 63. For example, when the display device 64 is OFF, the pattern of the pattern layer 66 of the light-transmitting decorative film 62 is visible from the front side of the display device 100. At this time, the color tone of the pattern of the pattern layer 66 is controlled by the color of the smoke panel 63. For example, if the color of the smoke panel 63 is brown and the pattern of the pattern layer 66 is wood grain, a brownish wood grain can be seen from the front side of the display device 100.
- the smoke panel 90 may be thinned by cutting a part of it, but this may change the total light transmittance of that part. If this changes the color tone, it is preferable to match the color tone with a black sheet or paint.
- the display device 64 may be embedded in an opening in the surrounding wall 69 (see Figures 23 and 24). It may also be installed on the back of the wall so as to cover the opening in the wall 69.

- heat fusion a film may be laminated on the printed layer.
- the color of the wall 69 surrounding the display device 64 may be any color as long as it does not affect the color tone of the light-transmitting film 62, but if it is affected by the color of the base, it is preferable to use a color similar to the color of the display that does not project images.
- a further concealing layer is partially added behind the concealing layer 67 of the light-transmitting decorative film 62, the same concealing ink may be printed at a higher concentration, or a black or gray film or sheet may be attached.
- the decorative panel 200 according to the comparative example includes a light-transmitting decorative film 62 and a transparent plate 92, and does not include a smoke panel 63.
- the display device 300 according to the comparative example covers the display device 64 with the decorative panel 200.
- the back surface of the transparent plate 92 is an air layer as shown in Figs. 28 and 29
- the incident light LIN incident from the front surface of the light-transmitting decorative film 62 is reflected by the back surface of the transparent plate 92.
- the reflected light LOUT1 at the air layer interface illuminates the light-transmitting decorative film 62 from the back surface, causing the color tone of the light-transmitting decorative film 62 to become lighter.
- the display device 64 is ON, if the image LIMG1 of the display device 64 passes through the decorative panel 200, there is a problem that the contrast of the image LIMG1 deteriorates.
- the image LIMG of the display device 64 is projected by the concealment layer 67 (projected image LIMG2). Therefore, when viewed from an oblique angle, the image appears double and blurred due to the influence of the image LIMG1b directed obliquely and the projected image LIMG2, resulting in a problem of poor visibility.
- the concealment properties of the light-transmitting decorative film 62 are reduced, there is a problem in that the underlying material will be visible.
- a colored transparent smoke panel 63 having a total light transmittance of 3% or more and 40% or less is attached to the light-transmitting decorative film 62. Therefore, the reflected light LOUT1 generated by the incident light LIN incident from the front surface of the light-transmitting decorative film 62 being reflected by the rear surface of the decorative panel 61 is reduced. Therefore, it is possible to prevent the color tone of the light-transmitting decorative film 62 from becoming lighter and the contrast of the image LIMG1 of the display device 64 on the rear surface from being deteriorated by the illumination from the rear surface of the light-transmitting decorative film 62.
- the base concealing properties are improved, and the influence of the difference in the color of the transparent base is reduced, thereby preventing the color tone of the light-transmitting decorative film 62 from changing.
- the smoke panel 63 may control the color tone of the light-transmitting decorative film 62 by the color of the smoke panel 63.
- the color of the smoke panel 63 can be used to control the light-transmitting decorative film 62 to a desired color tone.
- the light-transmitting decorative film 62 may include a concealing layer 67. This allows the color tone of the light-transmitting decorative film 62 to be controlled using the concealing layer 67 and the smoke panel 63.
- the smoke panel 63 may be used as a concealing layer.
- the concealing layer 67 of the light-transmitting decorative film 62 can be omitted.
- the display device 100 is configured by concealing the display device 64 with the decorative panel 61 described above. In this case, deterioration of the contrast of the image on the display device 64 constituting the display device 100 can be suppressed.
- the display method is to adjust the RGB bias and gain of the display device 64 covered by the decorative panel 61 described above according to the color tone of the smoke panel 63, so that the white display appears white through the smoke panel 63.
- the color tone of the image of the display device 64 visible from the front of the decorative panel 61 can be adjusted.
- the display device 100 is adjusted using the display method described above.
- the color tone of the image on the display device 64 that can be seen from the front of the decorative panel 61 can be adjusted. For example, in the case of brown smoke, white that previously appeared reddish can be made to appear whiter by lowering the R gain and bias values in the display settings.
- the decorative panel 200 has a problem that the image is blurred when viewed from an oblique angle. If the light from the display device 64 is largely diffusely reflected by the concealing layer 67, the image is formed by the concealing layer 67. In particular, if the concealing layer 67 is white, the light is likely to be diffusely reflected. When an interference pigment is used, a black layer may be formed as the concealing layer 67 to improve color development. In this case, diffuse reflection is less likely to occur than in a white concealing layer.
- the image of the display device 64 is not projected through the concealing layer 67, so that the image is not seen in double due to the light from the display device 64 and the concealing layer 67, and the display does not appear blurred through the decorative panel 200 even when viewed from an oblique angle.
- the concealing property is low, the display device 64 and its surroundings are visible through the decorative panel 200, and the base cannot be concealed.
- the decorative panel 61 combines a light-transmitting decorative film 62, which has low concealing properties and through which an image from a display device 64 passes without being projected onto the concealing layer, with a smoke panel 63, so that images are not seen in double on the display device 64 and the light-transmitting decorative film 62, and the image does not become blurred when viewed from an angle.
- a smoke panel 63 so that images are not seen in double on the display device 64 and the light-transmitting decorative film 62, and the image does not become blurred when viewed from an angle.
- concealing the base it is possible to prevent the reflected light LOUT1 reflected on the back side of the decorative panel 61 from illuminating the light-transmitting decorative film 62 from behind.
- Comparative Example 1 A specific comparative example 1 will be described with reference to FIG. 29.
- a 75 ⁇ m PET resin was used as the printing substrate 65.
- a wood grain pattern picture layer 66 was printed on the back of the print substrate 65, and a solid white layer was printed on the back of the print substrate 65 to form a concealing layer 67.
- the solid white layer controls the color tone of the picture and conceals the base, and a light-transmitting decorative film 62 was obtained by printing the light-transmitting decorative film 62 at a thickness such that the total light transmittance of the light-transmitting decorative film 62 is 17%.
- a transparent acrylic plate with a total light transmittance of 90% or more was attached to the back side of the light-transmitting decorative film 62 as a transparent plate 92 to produce a decorative panel 200.
- the decorative panel 200 was attached to a gray-colored wall 69 around the display device 64, and the display device 64 installed on the wall 69 and the gray-colored wall 69 around the wall 69 were concealed. Even if the light-transmitting decorative film 62 has high base concealment properties, it is light-transmitting, so when a transparent plate 92 is used as a base, the incident light LIN that enters through the sheet is reflected at the interface between the transparent plate 92 and the air layer, and illuminates the light-transmitting decorative film 62 from the back side.
- the color tone becomes whitish and the pattern becomes lighter.
- the reflected light LOUT2 becomes brighter, so that it can be made to be the same as the reflected light LOUT1 reflected at the interface with the air layer on the back side of the transparent plate 92, and the difference in color tone can be eliminated.
- the color tone of the light-transmitting decorative film 62 becomes whitish overall, and the contrast of the image of the display device through the light-transmitting decorative film 62 decreases.
- the comparative example 1 unlike the comparative example 2 described later, there is no difference in color tone between the image display part 95 and the surrounding parts, but the color tone becomes lighter overall (see FIG. 29(b)).
- the optically transparent decorative film 62 since the optically transparent decorative film 62 has a high concealing property, the image LIMG1 of the display device 64 is projected onto the concealing layer 67. Therefore, when viewed from an oblique angle, the image LIMG1b from the display device and the projected image LIMG2 projected onto the concealing layer 67 appear double, causing the image to appear blurred.
- Comparative Example 2 A specific comparative example 2 will be described with reference to FIG. 30. Comparative example 2 is similar to comparative example 1, except that the display device 64 installed on the wall 69 and the black wall 69 around it are concealed. When the black wall 69 is attached to the back side of the transparent plate 92, the reflected light LOUT2 becomes dark, and there is a difference in brightness between the reflected light LOUT1 reflected at the interface with the air layer on the back side of the transparent plate 92. Therefore, there is a difference in color tone between the light-transmitting decorative film 62 to which the black wall 69 is attached and the light-transmitting decorative film 62 at the part facing the display device 64. As a result, the image display portion 95 stands out in a light color tone (see FIG. 30(b)). Since the color tone of the image display portion 95 looks different, the presence of the display device 64 cannot be concealed as a result. Other problems are similar to those of comparative example 1.
- Example 2-1 A specific example 2-1 will be described with reference to FIG. 23.
- a 75 ⁇ m PET film was used as a printing substrate 65, a wood grain patterned picture layer 66 was printed on the reverse side using an inorganic pigment, and a solid white layer was printed thereon to form a concealing layer 67.
- the solid white layer has the effect of controlling the color tone of the picture and preventing the picture from sinking into the black of the base and becoming difficult to see.
- the printing density of the solid white printing was lowered and printed thinly to reduce the base concealment, and a light-transmitting decorative film 62 with a total light transmittance of 25% was obtained.
- a smoked acrylic plate with a total light transmittance of 28% was attached to the back side of the light-transmitting decorative film 62 as a brown smoke panel 63 to produce a decorative panel 61.
- the decorative panel 61 was attached to the black wall 69 surrounding the display device 64 installed on the wall 69, and the display device 64 installed on the wall 69 and the black wall 69 around it were concealed.
- a liquid crystal monitor with a brightness of 700 cd was used as the display device 64.
- the brown smoke acrylic plate it was possible to prevent the color tone of the pattern from becoming dark even if the printing density of the solid white of the concealing layer 67 was reduced. Since the smoke acrylic plate has a small reflection of the incident light LIN, it is possible to suppress the light-transmitting decorative film 62 from being illuminated from the back, and the color tone was not lightened. Therefore, the difference in color tone was not visible between the part attached to the black wall 69 and the image display part 95 facing the display device 64. In addition, by using brown smoke as the smoke panel 63, the color tone was not blackened as compared to the use of gray smoke.
- the image of the display device 64 was visible with high contrast through the sheet.
- the concealing property of the light-transmitting decorative film 62 is low, the image of the display device 64 is not projected onto the concealing layer 67, and even when viewed from an oblique angle, the image LIMG1b from the display device 64 and the image projected onto the concealing layer 67 do not appear double and the image does not become blurred.
- the reflected light LOUT2 of the incident light LIN reflected by the black wall 69 and the reflected light LOUT1 of the incident light LIN reflected by the interface with the air layer of the smoke panel 63 are almost equal, and there is no visible difference in color tone between the two, so the image display portion 95 does not appear bright.
- Example 2-2 A specific example 2-2 will be described with reference to FIG. 23.
- a 75 ⁇ m PET resin was used as a printing substrate 65, a wood grain patterned picture layer 66 was printed on the back using an interference pigment, and a black solid layer was printed on the back to form a concealing layer 67.
- the black solid layer has the effect of making the color of the interference pigment more visible and concealing the base.
- the print density was lowered and thin printing was performed to reduce the base concealment, and a light-transmitting decorative film 62 with a total light transmittance of 60% was obtained.
- a gray smoked acrylic plate with a total light transmittance of 18% and a thickness of 3 mm was attached as a smoke panel 63 to the back side of the light-transmitting decorative film 62, to produce a decorative panel 61.
- the decorative panel 61 was attached to the black wall 69 surrounding the display device 64 installed on the wall 69, and the display device 64 installed on the wall 69 and the black wall 69 surrounding it were concealed.
- Combining the smoked acrylic plate and the light-transmitting decorative film 62 increased the base concealment, and even the light-transmitting decorative film 62 with low base concealment was able to conceal the display device 64 and the surrounding wall 69.
- the smoked acrylic plate has low reflection of the incident light LIN, so it can suppress illuminating the light-transmitting decorative film 62 from the back. Therefore, the color tone did not become lighter, and no difference in color tone was seen between the part attached to the black wall 69 and the image display part 95 facing the display device 64. In addition, it was possible to suppress the color tone from becoming lighter, as in Example 1 for comparison. In addition, by using gray smoke for the smoked acrylic, the color development of the interference pigment was improved.

Description
特許第5725581号公報に記載の印刷物は、第1色パターン層、第2色パターン層、及び第3色パターン層を備えており、それぞれのパターン層が含む顔料チップが、赤色干渉顔料、緑色干渉顔料及び青色干渉顔料のいずれかである。この印刷物では、従来の印刷よりも色の発色を鮮やかにするために、パターン層の数が多くなっている。特許第6839319号公報に記載の加飾シートは、複数種類の干渉顔料を含み、第1混色を呈する第1図柄層と、複数種類の干渉顔料を含み、当該第1混色とは異なる第2混色を呈する第2図柄層と、を備える。この加飾シートでは、第1図柄層及び第2図柄層のそれぞれが複数種類の干渉顔料を含むため、印刷時の調色作業や見当合わせ作業が煩雑となるおそれがある。
図1は、第1-1実施形態に係る表示装置を模式的に示す断面図である。図2は、図1に示す表示装置が備える絵柄印刷層を模式的に示す断面図である。表示装置1は、図1に示すように、印刷物2と、光源3とを備える。印刷物2は、絵柄を表現するためのシートであり、透光性基材4と、絵柄印刷層5と、透過性スモーク印刷層30と、を備える。印刷物2は、光源3の前方(視認者と光源3との間)に設けられる。印刷物2は、全光線透過性を有する。このため、光源3の電源がONの際は、視認者は、印刷物2を透過した光源3からの光を視認でき、光源3の電源がOFFの際は、視認者は、印刷物2が表現する絵柄を視認することができる。光源3は、例えば、ディスプレイ装置である。
以下では、図3及び図4を参照しながら、第1-2実施形態に係る印刷物2Aを説明する。なお、第1-2実施形態の説明において上記第1-1実施形態と重複する記載は省略し、上記第1-1実施形態と異なる部分を記載する。つまり、技術的に可能な範囲において、第1-2実施形態に上記第1-1実施形態の記載を適宜用いてもよい。
以下では、図5を参照しながら、第1-3実施形態に係る印刷物2Bを説明する。なお、第1-3実施形態の説明において上記第1-1、第1-2実施形態と重複する記載は省略し、上記第1-1、第1-2実施形態と異なる部分を記載する。つまり、技術的に可能な範囲において、第1-3実施形態に上記第1-1、第1-2実施形態の記載を適宜用いてもよい。
以下では、図6を参照しながら、第1-4実施形態に係る印刷物2Cを説明する。なお、第1-4実施形態の説明において上記第1-1、第1-2、第1-3実施形態と重複する記載は省略し、上記第1-1、第1-2、第1-3実施形態と異なる部分を記載する。つまり、技術的に可能な範囲において、第1-4実施形態に上記第1-1、第1-2、第1-3実施形態の記載を適宜用いてもよい。
特許第5725581号公報に記載された印刷物等では、干渉顔料の粒径によって図柄(絵柄)の発色性が劣化する場合がある。絵柄の色彩を視認者が良好に認識できるように、優れた発色性を有する印刷物が望まれる。一方、特許第6839319号公報に記載された印刷物等は、電源がオフの際には黒い画面となるディスプレイを有する表示装置の前方に置かれる場合がある。この場合、電源がオフの際に、印刷物の絵柄が暗く見えてしまい、絵柄の視認性が悪化するおそれがある。
本実施形態に係る印刷物、及び表示装置として、図1に示すものと同趣旨の構成を採用してよい。従って、本実施形態に係る印刷物、及び表示装置において、第1-1実施形態の印刷物、及び表示装置と同趣旨の構成については説明を省略する。第2-1実施形態に係る印刷物、及び表示装置は、図2に示す層構成に代えて、図7に示す層構成が採用されている。
ここで、絵柄印刷層に含まれる二酸化チタン被覆雲母の粒径による、液晶モニターの映像と絵柄との見え方の傾向について、実験例を用いて説明する。図8及び後述する実験例1~3に示すように、二酸化チタン被覆雲母の粒径を調整した印刷物を作製した。図8は、実験例1~3に係る印刷物の構成を示す図表である。実験例1~3に係る印刷物の裏面側(透過性スモーク印刷層側)に液晶モニターを設置した。印刷物と液晶モニターとの間の距離は2mmとした。液晶モニターの電源がオンの状態とオフの状態の視認性(後述する項目1~4)を評価した。項目1~4に対して、4人により官能評価を実施し、評点の平均点を算出した。
透明PETである透明基材上に、第1色パターン層、第2色パターン層、白色パターン層、及び、透過性スモーク印刷層を順に設けることにより印刷物を作製した。実験例1では、第1色用バインダー(ウレタン系樹脂)と第1色用バインダーの内部に分散された赤色干渉顔料及び金色干渉顔料とを含むインキを用いて、スクリーン印刷技術により第1色パターン層を形成した。赤色干渉顔料及び金色干渉顔料の含有率として、第1色用バインダーを100重量部とした場合、10~40μmの粒径を有する赤色干渉顔料を8重量部、5~25μmの粒径を有する赤色干渉顔料を2重量部、10~60μmの粒径を有する金色干渉顔料を5重量部、及び、5~25μmの粒径を有する金色干渉顔料を2重量部とした。

特許第5725581号公報に記載の印刷物は、第1色パターン層、第2色パターン層、及び第3色パターン層を備えており、それぞれのパターン層が含む顔料チップが、赤色干渉顔料、緑色干渉顔料及び青色干渉顔料のいずれかである。この印刷物では、従来の印刷よりも色の発色を鮮やかにするために、パターン層の数が多くなっている。特許第6839319号公報に記載の加飾シートは、複数種類の干渉顔料を含み、第1混色を呈する第1図柄層と、複数種類の干渉顔料を含み、当該第1混色とは異なる第2混色を呈する第2図柄層と、を備える。
本実施形態に係る印刷物、及び表示装置として、図1に示すものと同趣旨の構成を採用してよい。従って、本実施形態に係る印刷物、及び表示装置において、第1-1実施形態の印刷物、及び表示装置と同趣旨の構成については説明を省略する。本実施形態に係る印刷物、及び表示装置は、図2に示す層構成に代えて、図9に示す層構成が採用されている。

ここで、特許第5725581号公報、特許第6839319号公報のように、印刷層の下に光源を備える装置においては、光源が消灯しているとき、当該光源の表面が黒色の状態となる。このとき、印刷層の絵柄の色合いが、光源の表面の黒色の影響を受ける場合がある。当該状態においては、絵柄の外観が、実際の絵柄の色合いと異なるように見えるという問題がある。
本実施形態に係る印刷物、及び表示装置は、図1に代えて、図15に示す構成を採用する。図15に示すように、印刷物2は、絵柄を表現するためのシートであり、透光性基材4と、絵柄印刷層5と、透過性スモーク印刷層30と、反射層50と、を備える。なお、印刷物2のうち、反射層50以外の層をまとめて本体部55と称する場合がある。本実施形態に係る印刷物、及び表示装置は、第1~4及び第6の開示に係る印刷物、表示装置に対して、反射層50を追加した点以外は、同趣旨の構成を採用してもよい。本実施形態に係る印刷物、及び表示装置において、第1-1実施形態の印刷物、及び表示装置と同趣旨の構成については説明を省略する。
従来、ディスプレイ装置の前に光透過性化粧フィルムを設置し、ディスプレイ装置を隠蔽する化粧フィルムが提案されている(例えば、特開2022-167552号公報参照)。光透過性化粧フィルムの隠蔽層に隠蔽性と光透過性を持たせることで、ディスプレイ装置を隠蔽し、かつ、ディスプレイ装置の画像を化粧パネル上に投影することができる。
図29を参照して、具体的な比較となる実施例1について説明する。比較となる実施例1では、75μmのPET樹脂を印刷基材65とした。そこに木目柄の絵柄層66を裏刷りし、その上に白ベタ層を印刷して隠蔽層67を形成した。白ベタ層は、絵柄の色調を制御すると共に下地を隠蔽し、光透過性化粧フィルム62の全光線透過率が17%になる厚さで印刷した光透過性化粧フィルム62を得た。その光透過性化粧フィルム62の裏側に全光線透過率90%以上の透明アクリル板を透明板92として貼り、化粧パネル200を作製した。ディスプレイ装置64の周囲にあるグレーに着色した壁69にその化粧パネル200を貼り、壁69に設置したディスプレイ装置64とその周囲にあるグレーの色の壁69を隠蔽した。下地隠蔽性が高い光透過性化粧フィルム62であっても光透過性があるため、下地に透明板92を用いた場合は、シート越しに入射した入射光LINが透明板92と空気層の界面で反射し、光透過性化粧フィルム62を裏面から照らす。そのため、色調が白っぽくなり柄が薄くなってしまう。透明板92の裏側に色を調整したグレーの色の壁69を接着すると反射光LOUT2が明るくなるため、透明板92の裏側の空気層との界面で反射した反射光LOUT1と、同程度にすることができ、色調の違いをなくすことができる。しかし、反射光LOUT1,2により、光透過性化粧フィルム62の色調は全体的に白っぽくなり、光透過性化粧フィルム62越しのディスプレイ装置の画像のコントラストは低下する。比較となる実施例1では、後述の比較となる実施例2とは異なり、画像表示部分95と周囲の部分との間の色調に差はでないが、全体的に色調が薄くなる(図29(b)参照)。また、光透過性化粧フィルム62の隠蔽性が高いので、ディスプレイ装置64の画像LIMG1が隠蔽層67に投影される。そのため、斜めからみると、ディスプレイ装置からの画像LIMG1bと隠蔽層67に投影された投影画像LIMG2で二重に見えて画像がぼやけて見えてしまう。
図30を参照して、具体的な比較となる実施例2について説明する。比較となる実施例2は、壁69に設置したディスプレイ装置64とその周囲にある黒色の壁69を隠蔽した点以外は、比較となる実施例1と同様である。透明板92の裏側に黒色の壁69を接着すると反射光LOUT2は暗くなるので、透明板92の裏側の空気層との界面で反射した反射光LOUT1と、明るさに違いが出る。そのため、黒色の壁69を接着した光透過性化粧フィルム62と、ディスプレイ装置64と対向する箇所の光透過性化粧フィルム62とで色調に違いが生じてしまう。その結果、画像表示部分95が、薄い色調で浮き出てしまう(図30(b)参照)。画像表示部分95の色調が違ってみえるため、結果的にディスプレイ装置64の存在を隠蔽できていない。その他の問題点は、比較となる実施例1と同様である。
図23を参照して、具体的な実施例2-1について説明する。実施例2-1では、75μmのPETフィルムを印刷基材65とし、そこに無機顔料を用いて木目柄の絵柄層66を裏刷りし、その上に白ベタ層を印刷して隠蔽層67を形成した。白ベタ層は、絵柄の色調を制御し、下地の黒に絵柄が沈んでみえにくくなるのを防ぐ効果がある。白ベタ印刷の印刷濃度を下げて薄く印刷することで下地隠蔽性を低くし、全光線透過率25%の光透過性化粧フィルム62を得た。その光透過性化粧フィルム62の裏側に全光線透過率28%のスモークアクリル板をブラウンスモークパネル63として貼り、化粧パネル61を作製した。壁69に設置したディスプレイ装置64の周囲の黒い壁69にその化粧パネル61を貼り、壁69に設置したディスプレイ装置64とその周囲にある黒の色の壁69を隠蔽した。ディスプレイ装置64として、輝度700cdの液晶モニターを用いた。ブラウンスモークアクリルと組み合わせることで下地隠蔽性が高まり、下地隠蔽性の低い光透過性化粧フィルム62でもディスプレイ装置64と周囲の壁69を隠蔽できた。また、ブラウンスモークアクリル板を使用することで、隠蔽層67の白ベタの印刷濃度が下がっても、絵柄の色調が暗くなるのを防ぐことができた。スモークアクリル板は、入射光LINの反射が小さいため、光透過性化粧フィルム62を裏面から照らすことを抑制でき、色調が薄くならなかった。このため、黒い壁69に貼った部分とディスプレイ装置64と対向する部分の画像表示部分95で色調の違いは見えなかった。また、スモークパネル63として、ブラウンスモークを用いることで、グレースモークを使用するよりも色調が黒くならなかった。光透過性化粧フィルム62の表面が白っぽくならないため、ディスプレイ装置64の画像は、シート越しに高いコントラストで視認できた。また、光透過性化粧フィルム62の隠蔽性が低いので、ディスプレイ装置64の画像が隠蔽層67に投影されず、斜めからみても、ディスプレイ装置64からの画像LIMG1bと隠蔽層67に投影された画像で二重に見えて画像がぼやけることがなかった。入射光LINが黒い壁69で反射した反射光LOUT2と、スモークパネル63の空気層との界面で反射した反射光LOUT1はほぼ等しく、両者で色調の違いが見えないため、画像表示部分95が明るく見えることがない。
図23を参照して、具体的な実施例2-2について説明する。実施例2-2では、75μmのPET樹脂を印刷基材65とし、そこに木目柄の絵柄層66を干渉顔料を用いて裏刷りし、その上に黒ベタ層を印刷して隠蔽層67を形成した。黒ベタ層は、干渉顔料の発色を見えやすくし、下地を隠蔽する効果がある。印刷濃度を下げて薄く印刷することで下地隠蔽性を低くし、全光線透過率60%の光透過性化粧フィルム62を得た。その光透過性化粧フィルム62の裏側に全光線透過率が18%で3mm厚のグレースモークアクリル板をスモークパネル63として貼りつけ、化粧パネル61を作製した。壁69に設置したディスプレイ装置64の周囲の黒い壁69にその化粧パネル61を貼り、壁69に設置したディスプレイ装置64とその周囲の黒い壁69を隠蔽した。スモークアクリル板と光透過性化粧フィルム62とを組み合わせることで下地隠蔽性が高まり、下地隠蔽性の低い光透過性化粧フィルム62でもディスプレイ装置64と周囲の壁69を隠蔽できた。スモークアクリル板は、入射光LINの反射が小さいため、光透過性化粧フィルム62を裏面から照らすことを抑制できる。そのため、色調が薄くならず、黒い壁69に貼った部分とディスプレイ装置64と対向する部分の画像表示部分95で色調の違いは見えなかった。また、比較となる実施例1のように色調が薄くなることが抑制できた。また、スモークアクリルはグレースモークを使用することで、干渉顔料の発色がよくなった。また、光透過性化粧フィルム62の隠蔽層67の隠蔽性が低くかつ色が黒なので、ディスプレイ装置64の画像LIMG1が隠蔽層67に投影されず、斜めからみても、ディスプレイ装置64からの画像LIMG1bと隠蔽層67に投影された画像で二重に見えて画像がぼやけることがなかった。入射光LINが黒い壁69で反射した反射光LOUT2と、スモークパネル63の空気層との界面で反射した反射光LOUT1はほぼ等しく、両者で色調の違いが見えないため、画像表示部分95が明るく見えることがない。
図24を参照して、具体的な実施例2-3について説明する。実施例2-3は、実施例2-2から隠蔽層67を省略したものである。実施例2-3では、光透過性化粧フィルム62に隠蔽層67がないため、ディスプレイ装置64の画像LIMG1が隠蔽層67に投影されず、斜めからみても、ディスプレイ装置64からの画像LIMG1bと隠蔽層67に投影された画像で二重に見えて画像がぼやけることがなかった。その他の効果は実施例2-2と同様であるが、隠蔽層67をなくすことで、ディスプレイ装置64からの画像をより明るくすることができる。
