Description

  One aspect of the present invention relates to a decorative sheet. Another aspect of the present invention relates to an interior structure including a decorative sheet.

  There is known a technique for providing a sign indicating the direction of an exit with an arrow or a character for emergency use (Patent Application Publication No. 211798). In this sign, a green display is made on a white background so that an indicator is conspicuous, and conversely, a green character is made on a white background. In addition, a retroreflective material is used for this sign.

Canadian Patent Application Publication No. 211798

  It is important that the display is conspicuous in an emergency, but if it is always conspicuous, there is a possibility that the decoration applied around the display may be damaged from the viewpoint of design.

  A decorative sheet according to one aspect of the present invention is a decorative sheet provided with sign information, and includes a retroreflective portion and a non-retroreflective portion, and a surface of the retroreflective portion is the non-reflective portion. Provided with at least one of the same color and the same pattern with respect to the surface of the retroreflective portion, and the marker information is provided on one of the surface of the retroreflective portion and the surface of the non-recursive reflective portion. ing.

  The retroreflecting unit has a function of mainly reflecting light toward the light source direction. Therefore, when the decorative sheet is illuminated in the dark, the retroreflecting part reflects more light toward the light source direction than the non-recursive reflecting part. As a result, for a person who looks at the decorative sheet while illuminating the decorative sheet, the retroreflective portion and the non-retroreflective portion are relatively easily distinguished, and the difference between the two is conspicuous. On the other hand, since the retroreflective part and the non-retroreflective part are provided with at least one of the same color and the same pattern, they are relatively relative when the entire space is brightly illuminated by light such as natural light or fluorescent light. It is difficult to distinguish between the two, and the difference between the two is inconspicuous. In other words, in the above decorative sheet, either one of the retroreflective part and the non-retroreflective part is provided with the sign information. Therefore, when illuminated in the dark, the distinction between the two becomes clear, and the sign information Stands out. On the other hand, when the whole space is bright, it is difficult to distinguish between the retroreflective part and the non-retroreflective part, so the sign information is not noticeable. As a result, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information is not conspicuous and the decorativeness is not easily lost.

In the decorative sheet according to one aspect, the reflective performance of the retroreflective portion is 1 Cd / Lx / m ² or more, and the reflective performance of the non-recursive reflective portion may be lower than the reflective performance of the retroreflective portion.

  In the decorative sheet according to one aspect, the color difference between the surface of the retroreflective portion and the surface of the non-retroreflecting portion may be 30 or less.

  An interior structure according to another aspect of the present invention includes a base material that forms at least a part of the interior surface, and a decorative sheet attached to the base material, wherein the base material is at least one around the decorative sheet. The decorative sheet has a retroreflective part, and the surface of the retroreflective part of the decorative sheet has the same color and the same color as the surface of the nonretroreflective part of the substrate. At least one of the system patterns is provided, and sign information is provided on the surface of the retroreflective portion of the decorative sheet.

  Since this interior structure is provided with sign information on the retroreflective portion of the decorative sheet, the sign information is conspicuous when illuminated in the dark. On the other hand, when the entire space is bright, the base information and the decorative sheet are difficult to distinguish from each other, and the sign information is not conspicuous. As a result, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information is not conspicuous and the decorativeness is not easily lost.

In the interior structure according to one aspect, the reflective performance of the retroreflective portion is 1 Cd / Lx / m ² or more, and the reflective performance of the non-recursive reflective portion of the base material is more than the reflective performance of the retroreflective portion of the decorative sheet. It may be low.

  In the interior structure according to one aspect, the color difference between the surface of the retroreflective portion of the decorative sheet and the surface of the non-retroreflecting portion of the base material may be 30 or less.

  In the interior structure according to one aspect, the surface of the decorative sheet may further include another non-recursive reflection portion.

  According to one aspect of the present invention, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information is not conspicuous and the decorativeness is not easily impaired.

FIG. 1 is a diagram illustrating an example of a decorative sheet according to an embodiment of the present invention. FIG. 2 is a diagram illustrating another example of the decorative sheet according to the embodiment of the present invention. FIG. 3 is a view showing still another example of the decorative sheet according to the embodiment of the present invention. FIG. 4 is a diagram illustrating an example of an interior structure according to the embodiment of the present invention. FIG. 5 is a view showing another example of the interior structure according to the embodiment of the present invention.

  An embodiment of the present invention is a decorative sheet provided with sign information, and includes a retroreflecting portion and a non-retroreflecting portion, and the surface of the retroreflecting portion is the surface of the non-retroreflecting portion In contrast, at least one of the same-system color and the same-system pattern is provided, and the label information is provided on either the surface of the retroreflective portion or the surface of the non-retroreflecting portion.

  In this decorative sheet, the retroreflective portion has a function of mainly reflecting light toward the light source direction of light. Therefore, when the decorative sheet is illuminated in the dark, the retroreflecting part reflects more light toward the light source direction than the non-recursive reflecting part. As a result, for a person who looks at the decorative sheet while illuminating the decorative sheet, the retroreflective portion and the non-retroreflective portion are relatively easily distinguished, and the difference between the two is conspicuous. On the other hand, the retroreflective part and the non-retroreflective part have a common appearance, so it is relatively difficult to distinguish when the entire space is brightly illuminated by light such as natural light or fluorescent lamps. Is inconspicuous. In other words, in the above decorative sheet, either one of the retroreflective part and the non-retroreflective part is provided with the sign information. Therefore, when illuminated in the dark, the distinction between the two becomes clear, and the sign information Stands out. On the other hand, when the whole space is bright, it is difficult to distinguish between the retroreflective part and the non-retroreflective part, so the sign information is not noticeable. As a result, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information is not conspicuous and the decorativeness is not easily lost.

  Another embodiment of the present invention is an interior structure, and includes a base material that forms at least a part of the interior surface, and a decorative sheet attached to the base material, the base material surrounding the decorative sheet At least a part is provided with a non-retroreflective part, the decorative sheet is provided with a retroreflective part, and the surface of the retroreflective part of the decorative sheet is the same color as the surface of the non-retroreflective part of the substrate And at least one of the same system pattern is provided, and the marker information is provided on the surface of the retroreflective portion of the decorative sheet.

  In this interior structure, since the sign information is provided in the retroreflective portion of the decorative sheet, the sign information is conspicuous when illuminated in the dark. On the other hand, when the entire space is bright, the base information and the decorative sheet are difficult to distinguish from each other, and the sign information is not conspicuous. As a result, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information is not conspicuous and the decorativeness is not easily lost.

  Note that the “label information” in the present specification broadly includes information that allows a specific meaning to be grasped by visual recognition (identification information in a narrow sense) and information that can serve as a landmark by identifying itself and others (in a broad sense). For example, the sign information in a narrow sense in a building includes emergency exits, evacuation passages, and other information. In addition, the sign information in a broad sense includes a wide range of signs indicating the presence of indoor doors, windows, walls, etc., signs that guide you to specific destinations such as emergency exits and emergency stairs, and other information. . The “non-recursive reflection portion” means a portion that does not have a retroreflection function. “Reflection performance” is a value measured according to JISZ 9117 (2011), and the luminosity and reflection received by the reflective material placed perpendicular to the direction of the incident light. It is defined as the value divided by the product of the area of the material. The reflection performance indicates measured values at an incident angle of 5.0 degrees and an observation angle of 0.2 degrees. In this specification, the term “sheet” includes a flexible film, a sheet, a rigid sheet, and a plate-like body.

  Hereinafter, embodiments of a decorative sheet and an interior structure will be described in detail with reference to the drawings. In this description, the same reference numerals are used for the same elements, and duplicate descriptions are omitted.

  FIG. 1 is a diagram illustrating an example of a decorative sheet according to an embodiment of the present invention. 1A shows a front view of a decorative sheet under an indoor light source, and FIG. 1B shows a cross-sectional view of the decorative sheet along the line Ib-Ib in FIG.

As shown in FIGS. 1A and 1B, the decorative sheet 1A includes a retroreflecting portion 10 and a non-retroreflecting portion 20, and the retroreflecting portion 10 is in the light source direction of incident light. And has a function of reflecting light mainly. As a result, the reflection performance of the retroreflecting unit 10 toward the light source direction is at least greater than 1 Cd / Lx / m ² , for example, ² Cd / Lx / m ² or more, and further 5 Cd / Lx / M ² or more. The reflection performance of the non-recursive reflection unit 20 is set lower than the reflection performance of the retroreflection unit 10, and is, for example, 1 Cd / Lx / m ² or less.

Specifically, the retroreflective portion 10 can be used without particular limitation as long as it is a retroreflective sheet. For example, a commercially available glass bead type or prism type retroreflective sheet can be used. For example, as the glass bead type retroreflective sheet, Scotchlite ^TM reflective sheet 680 series (manufactured by 3M Japan) can be used. The non-recursive reflection part 20 can be used without limitation as long as it is a marking sheet. For example, a Scotchal ^TM film (manufactured by 3M Japan) can be used. For example, as a result of the reflection sheet 680-85 having a retroreflection function, the reflection performance is 22.9 Cd / Lx / m ² (the reflection light of the reflection sheet 680-85 is white). On the other hand, in the Scotchical ^TM film JS1500XL, substantially no retroreflection occurs, and the reflection performance is 1 Cd / Lx / m ² or less.

  The planar shape of the retroreflective sheet and its size are not particularly limited. For example, it can be in the form of a tape that is long in one direction, or it can be a rectangular or polygonal shape shown in FIG. For example, it can be used in a tape form of 5000 mm × 80 mm, cut to a desired length. The retroreflective sheet and the marking sheet can have an adhesive layer on the back surface, and the thickness is, for example, 180 μm including the adhesive layer. The thickness of the marking sheet JS1500XL is, for example, 80 μm including the adhesive layer.

  The decorative sheet 1 </ b> A has sign information 30, and the sign information 30 is provided on either the surface 10 a of the retroreflective portion 10 or the surface 20 a of the non-retroreflecting portion 20. FIGS. 1A and 1B show an example in which the surface 20 a of the non-recursive reflection unit 20 becomes the sign information 30. That is, the marking sheet JS1500XL which is the non-recursive reflection part 20 forms the sign information 30 in the shape of an arrow and the shape of Exit.

  The surface 10 a of the retroreflective portion 10 can have at least one of the same color and the same pattern with respect to the surface 20 a of the non-recursive reflective portion 20. The same color means that they belong to the same group as a basic color. Specifically, the basic colors of chromatic colors are red, yellow-red, yellow, yellow-green, green, blue-green, blue, blue-violet, purple, and magenta. The achromatic basic colors are white, gray, There are three types of black. When a plurality of colors are compared, if they are common as basic colors, they are of the same color, and in order to be common as basic colors, it is sufficient if the hues are the same. In addition, when at least one of the surface 10a of the retroreflective part 10 and the surface 20a of the non-recursive reflective part 20 includes a plurality of colors, if at least some of the colors belong to the same color, the recursion It can be said that the surface 10 a of the reflective reflector 10 has the same color as the surface 20 a of the non-recursive reflector 20.

  The same pattern means that it is the same kind of pattern. The types of patterns include, for example, natural patterns such as wood grain, plants, flowers, stones, sand, and skin that exist in nature, natural phenomenon patterns created using motifs such as polka dots, waves, and snow that exist in nature, and Geometric patterns created by combining shapes such as lines, circles, and polygons, and various artificially created patterns such as hairlines, carbon textures, metallic tones, textures, etc. Including widely. In addition, if the pattern of the surface 10a of the retroreflective part 10 and the pattern of the surface 20a of the non-retroreflective part 20 are the same kind, the color attached | subjected to the surface 10a of the retroreflective part 10, and a nonrecursive reflective part Even if the color given to the surface 20a of 20 does not belong to the same color, it can be said that the surface 10a of the retroreflective part 10 has the same pattern as the surface 20a of the non-recursive reflective part 20. .

  The retroreflecting unit 10 according to the present embodiment (see FIGS. 1A and 1B) is the same as the non-recursive reflecting unit 20 as an example of the same color for the nonrecursive reflecting unit 20. It has a color, for example a black surface. Specifically, the retroreflective sheet 680-85 that forms the retroreflective part 10 is a black sheet, and the marking sheet JS1500XL that forms the non-retroreflective part 20 is a black sheet.

  Since the retroreflective part 10 and the non-retroreflective part 20 have the same color, when the entire space where the decorative sheet 1A is installed is bright, for example, under an indoor light source, The sign information 30, that is, the shape of the arrow formed by the non-recursive reflection part 20 and the letters “Exit” are inconspicuous and difficult to visually recognize. The indoor light source is, for example, a fluorescent lamp, and is installed in a ceiling area having a height of about 2 m to 3 m from the floor area. In addition, the decorative sheet 1A is installed, for example, at a height of 1.5 m from the floor or lower. In FIG. 1A, the outline of the non-recursive reflection unit 20 is indicated by a broken line in order to indicate that the non-recursive reflection unit 20 is provided on the retroreflection unit 10.

  FIG. 1C is a front view of the decorative sheet 1A when the indoor light source is turned off and the hand light source is irradiated. The hand light source is, for example, an LED light source of a smartphone iPhone 5C (manufactured by Apple). When the decorative light source 1A is irradiated with the hand light source, the retroreflecting unit 10 performs retroreflection, and as a result, the shape of the arrow formed by the non-recursive reflecting unit 20 and the letters “Exit” are easily noticeable and the visibility is improved. improves.

  The hand light source may be an LED light source of a smartphone other than iPhone 5C, and may be a home flashlight, for example. The decorative sheet 1A can be installed, for example, in a range of 0.1 m to 2.2 m in height from the floor. This height is an area that easily enters the field of view of a person present in the building. However, under the indoor light source, the shape of the arrow formed by the non-recursive reflector 20 and the letters “Exit” are assimilated into the retroreflector 10. Hidden like a protective color, inconspicuous. On the other hand, when the indoor light source is turned off and the hand light source is irradiated, the non-recursive reflecting portion 20 becomes relatively darker than the retro-reflecting portion 10, and the sign formed by the non-recursive reflecting portion 20 The information 30 is conspicuous and has sufficient visibility.

In the decorative sheet 1A, the retroreflective portion 10 includes, for example, polyvinyl chloride, polycarbonate, acrylic, urethane, fluororesin, or other resin, and may have an adhesive layer on the back surface. Specifically, for example, a commercially available glass bead type or prism type retroreflective sheet can be used as the retroreflective portion 10. As a glass bead type retroreflection sheet, for example, Scotchlite ^TM reflection sheet 680 series (manufactured by 3M Japan) can be used. In addition to the Scotchlite ^TM reflective sheet 680-85, 680-10, 680-14, 680-72, 680-75, and 680-81 (manufactured by 3M Japan) may be used. The thickness of the retroreflective portion 10 is, for example, 180 μm including the adhesive layer.

The non-retroreflective part 20 includes, for example, polyvinyl chloride, polycarbonate, acrylic, urethane, fluororesin and other resins, and may have an adhesive layer on the back surface. As the non-recursive reflection part 20, a commercially available marking sheet can be used, for example, Scotchal ^TM film (made by 3M Japan) can be used. Specifically, JS1003XL, JS1006XL, JS1234XL, JS1408XL, JS1404XL, JS1604XL, IJ5341F, JS6106, and JS6616XL (manufactured by 3M Japan) can be used in addition to the Scotchcal ^TM film JS1500XL. The thickness of the non-retroreflective part 20 is 80 μm including the adhesive layer, for example.

  Further, when the entire space is bright, the sign information is not conspicuous, and in order to make it difficult to impair the decorativeness, as shown in Table 1, the surface 10a of the retroreflective portion 10 of the decorative sheet 1A and the non-recursive reflection are provided. The color difference from the surface 20a of the portion 20 can be 30 or less, can be 20 or less, and can be 10 or less.

  Table 1 is a table showing the reflection performance of the reflection sheet and the marking sheet included in the retroreflecting part 10 and the non-retroreflecting part 20, respectively. The names of the reflective sheet and the marking sheet in the table indicate the product name of 3M and the color of the surface of each sheet. Moreover, this table | surface shows the combination of each reflection sheet and each marking sheet, and is a table | surface which showed the color difference and the external appearance evaluation of the retroreflection part 10 and the non-retroreflection part 20 about the combination. In Table 1, “JS6804XL (moon beam metallic) + TP3113XL (lemon yellow)” means that the transmissive marking sheet TP3113XL is formed on the marking sheet JS6804XL.

  In the color difference measurement, the L * a * b * value of the decorative film was measured using a spectrocolorimeter CM-3700d (manufactured by Konica Minolta). The measurement light source was D65 and the observation angle was 10 degrees. Each reflective sheet and each marking sheet was irradiated with light, and L * a * b * values were measured.

The color difference ΔE * is calculated by expressing the L * a * b * values of the reflective sheet as L * 1, a * 1, b * 1, and the L * a * b * values of the marking sheet as L * 2. It was written as a * 2 and b * 2, and the following calculation formula was followed.
ΔE * = [(L * 2-L * 1) ² + (a * 2-a * 1) ² + (b * 2-b * 1) ² ] ^1/2
In the appearance evaluation shown in Table 1, when the entire space is bright, the sheet is evaluated as “A” when there is no difference in appearance between the sheet and the base material to which the sheet is adhered, and each sheet is adhered to the sheet. Evaluation was “B” when there was a clear difference in appearance from the substrate. Table 1 shows that the appearance evaluation is “A” when the color difference between the reflective sheet of the retroreflective portion 10 and the marking sheet of the non-retroreflective portion 20 is 30 or less.

  FIG. 2 is a diagram illustrating another example of the decorative sheet according to the embodiment of the present invention. 2A is a front view of the decorative sheet under the indoor light source, and FIG. 2B is a cross-sectional view of the decorative sheet along the line IIb-IIb in FIG.

As shown in FIGS. 2A and 2B, the decorative sheet 1B includes a retroreflecting portion 10 and a non-retroreflecting portion 20, and the retroreflecting portion 10 is in the light source direction of incident light. The reflection performance toward the light source direction is at least larger than 1 Cd / Lx / m ² , for example, ² Cd / Lx / m ² or more. Furthermore, it can be set to 5 Cd / Lx / m ² or more. The reflection performance of the non-recursive reflection unit 20 is set lower than the reflection performance of the retroreflection unit 10, and is, for example, 1 Cd / Lx / m ² or less.

As an embodiment, a retroreflective portion 10, specifically, include Scotchlite ^TM reflective sheet 680-85 (manufactured by 3M Japan), non-retroreflective portion 20, Scotchcal ^TM film is marking sheet Includes JS1500XL (manufactured by 3M Japan). As a result of the reflection sheet 680-85 having a retroreflection function, the reflection performance thereof is 22.9 Cd / Lx / m ² (the reflection light of the reflection sheet 680-85 is white). On the other hand, in the marking sheet JS1500XL, substantially no retroreflection occurs, and the reflection performance is 1 Cd / Lx / m ² or less.

  There is no particular limitation on the planar shape and size of the marking sheet. For example, it can be in the form of a tape that is long in one direction, or it can be a rectangular or polygonal shape as shown in FIG. For example, it can be made into a tape shape of 5000 mm × 80 mm and cut into a desired length for use. The retroreflective sheet and the marking sheet can have an adhesive layer on the back surface, and the thickness is, for example, 80 μm including the adhesive layer. The thickness of the retroreflective sheet 680-85 is 180 μm including the adhesive layer, for example.

  The decorative sheet 1 </ b> B has sign information 30, and the sign information 30 is provided on one of the surface 10 a of the retroreflective portion 10 and the surface 20 a of the non-recursive reflective portion 20. 2A and 2B show an example in which the surface 10a of the retroreflecting unit 10 becomes the sign information 30. FIG. In other words, the retroreflective sheet 680-85 which is the retroreflective portion 10 forms the sign information 30 in the shape of an arrow and the character “Exit”.

  The surface 10 a of the retroreflective portion 10 can have at least one of the same color and the same pattern with respect to the surface 20 a of the non-recursive reflective portion 20. The retroreflecting unit 10 according to the present embodiment (see FIGS. 2A and 2B) is the same as the non-recursive reflecting unit 20 as an example of the same color for the nonrecursive reflecting unit 20. It has a color, for example the same black surface. Specifically, the retroreflective sheet 680-85 that forms the retroreflective part 10 is a black sheet, and the marking sheet JS1500XL that forms the non-retroreflective part 20 is a black sheet.

  Since the retroreflective part 10 and the non-retroreflective part 20 have the same color, when the entire space in which the decorative sheet 1B is installed is bright, for example, under an indoor light source, the retroreflective part 10 and the non-recursive part It is difficult to distinguish from the reflecting portion 20, and the sign information 30, that is, the shape of the arrow formed by the retroreflecting portion 10 and the letters "Exit" are not conspicuous and are difficult to visually recognize. The indoor light source is, for example, a fluorescent lamp, and is installed in a ceiling area having a height of about 2 m to 3 m from the floor area. In addition, the decorative sheet 1A is installed, for example, at a height of 1.5 m from the floor or lower. In FIG. 2A, the outline of the retroreflecting unit 10 is indicated by a broken line in order to indicate that the retroreflecting unit 10 is provided on the non-recursive reflecting unit 20.

  FIG. 2C is a front view of the decorative sheet when the indoor light source is turned off and the hand light source is irradiated. The hand light source is, for example, an LED light source of a smartphone iPhone 5C (manufactured by Apple). When the decorative light source 1B is irradiated with the hand light source, the retroreflecting portion 10 performs retroreflecting, and as a result, the shape of the arrow formed by the retroreflecting portion 10 and the letters “Exit” are easily noticeable and the visibility is improved. To do.

  The hand light source may be an LED light source of a smartphone other than iPhone 5C, and may be a home flashlight, for example. The decorative sheet 1B can be installed, for example, in a range of 0.1 m to 2.2 m in height from the floor. This height is an area that easily enters the field of view of a person present in the building, but under the indoor light source, the shape of the arrow formed by the retroreflecting unit 10 and the letter “Exit” are assimilated into the non-recursive reflecting unit 20. Hidden like a protective color, inconspicuous. On the other hand, when the indoor light source is turned off and the hand light source is irradiated, the retroreflecting unit 10 becomes relatively brighter than the non-recursive reflecting unit 20 and the sign information formed by the retroreflecting unit 10. 30 is conspicuous and has sufficient visibility.

  Further, the color difference between the surface 10a of the retroreflective portion 10 and the surface 20a of the non-retroreflective portion 20 of the decorative sheet 1B in terms of making the sign information 30 inconspicuous when the entire space is bright and making it difficult to impair the decorativeness. Can be 30 or less, can be 20 or less, and can be 10 or less.

  FIG. 3 is a view showing still another example of the decorative sheet according to the embodiment of the present invention. 3A shows a front view of the decorative sheet under the indoor light source, and FIG. 3B shows a cross-sectional view of the decorative sheet along the line IIIb-IIIb in FIG.

  The decorative sheet 1C having the surface of the woodgrain pattern can be produced as follows. That is, first, a marking sheet JS1003XL for the non-retroreflective part 20 is prepared, and the retroreflective sheet 680-10 for the retroreflective part 10 is pasted on the marking sheet JS1003XL. The surface of the marking sheet JS1003XL is ice gray, and the surface of the retroreflective sheet 680-10 is white. The outline of the retroreflective sheet 680-10 forms the shape of an arrow and the letter “Exit”. Subsequently, the marking sheet JS1003XL to which the retroreflective sheet 680-10 is attached is subjected to woodgrain printing using a UV inkjet printer UJV500 (manufactured by Mimaki). As a result of this printing, the retroreflective sheet 680-10 and the marking sheet JS1003XL can have the same grained surface. In addition, the decorative sheet 1C having the surface of the woodgrain pattern is printed on the marking sheet serving as the non-recursive reflecting portion 20 and the reflecting sheet serving as the retroreflecting portion 10, respectively, separately printing the same woodgrain pattern. It is also possible to form by bonding so that the continuity of the pattern occurs.

  When the entire space in which the decorative sheet 1C is placed is bright because it has the same wood grain pattern surface, for example, under an indoor light source, the retroreflective sheet 680-10 of the retroreflective unit 10 and the non-recursive reflective unit 20 It is difficult to distinguish the marking sheet JS1003XL, and the sign information 30, that is, the shape of the arrow formed by the retroreflective portion 10 and the character “Exit” are assimilated to the non-retroreflecting portion 20 and are inconspicuous and difficult to impair decorativeness. In FIG. 3A, the outline of the non-recursive reflection unit 20 is indicated by a broken line in order to indicate that the retro-reflective unit 10 is provided on the non-recursive reflection unit 20.

  FIG. 3C shows a front view of the decorative sheet when the indoor light source is turned off and the hand light source is irradiated. The hand light source can be an LED light source of a smartphone iPhone 5C (manufactured by Apple). When this hand light source is applied to the decorative sheet 1C, the retroreflecting unit 10 performs retroreflecting. As a result, the retroreflecting unit 10 becomes relatively brighter than the non-recursive reflecting unit 20, and the retroreflecting unit 10C. The marker information 30 formed by the portion 10 is conspicuous and has sufficient visibility. Note that the decorative sheet 1C in FIG. 3 can be installed, for example, at a height of 0.1 m and 2.2 m from the floor, and even if installed at these positions, a retroreflective under an indoor light source. The shape of the arrow formed by the portion 10 and the letters “Exit” are inconspicuous and difficult to visually recognize. On the other hand, it has sufficient visibility when the indoor light source is turned off and the hand light source is irradiated.

  As described above, the retroreflecting unit 10 has a function of mainly reflecting light toward the light source direction. Therefore, when the decorative sheets 1A, 1B, and 1C are illuminated in the dark, the retroreflecting unit 10 reflects more light toward the light source direction than the non-recursive reflecting unit 20. As a result, for a person who views the decorative sheets 1A, 1B, and 1C while illuminating the decorative sheets 1A, 1B, and 1C, the retroreflective portion 10 and the non-recursive reflective portion 20 are relatively easily distinguished. The difference is conspicuous. On the other hand, since the retroreflective part 10 and the non-retroreflective part 20 have at least one of the same color and the same pattern, when the entire space is brightly illuminated by light such as natural light or a fluorescent lamp It is relatively difficult to distinguish, and the difference between the two is inconspicuous. That is, in the decorative sheets 1A, 1B, and 1C, since the marker information 30 is provided on one of the retroreflecting unit 10 and the non-recursive reflecting unit 20, when illuminated in the dark, both The distinction becomes clear and the sign information 30 stands out. On the other hand, when the whole space is bright, it is difficult to distinguish between the retroreflecting unit 10 and the non-retroreflecting unit 20, so that the sign information 30 is not noticeable. As a result, when illuminated in the dark, the function as a sign is effectively exhibited. On the other hand, when the entire space is bright, the sign information 30 is not conspicuous, and it is difficult to impair decorativeness.
