"Front side" is also used in the meaning of "more forward". In this embodiment, the front-rear direction is used in the same meaning as the thickness direction of the decorative sheet 51.

(Regarding the decorative sheet 51: first embodiment)
FIGS. 1A to 1F show enlarged cross-sectional views of the main part of a decorative sheet 51 according to a first embodiment of the present invention.
The decorative sheet 51 includes a translucent sheet body 1, a colored layer 52 of translucent colored ink disposed on the back side of the sheet body 1, a thickened portion 56 and a metallic reflective layer 57. And Here, in the present invention, "having translucency" means having a property of transmitting light, and a transparent or semitransparent material can be used.

(About the sheet body 1)
In addition to films and sheets made of synthetic resin such as cellulose acetate butyrate (CAB) resin, polyethylene terephthalate resin, polycarbonate resin, acrylic resin, olefin resin, ABS resin, vinyl chloride resin, etc. A glass plate etc. can be used, A single layer may be sufficient and the laminated body of two or more layers may be sufficient. The thickness of the sheet body 1 is not particularly limited, but generally 50 to 0 μm, preferably about 100 to 200 μm.

The sheet main body 1 has translucency, and as described later, as long as the colored layer 52, the thickened portion 56 and the metallic reflective layer 57 can be formed by a printing or transfer foil method or the like. The material and thickness do not matter. It is desirable that the base material has appropriate strength, durability, printing characteristics, and the like. The sheet main body 1 can select the most suitable one according to the physical property of the decorative article 72 provided with the decorative sheet 51 and the decorative sheet 51, and the processing method for obtaining the decorative article 72.

(About the colored layer 52)
A colored layer 52 made of a translucent colored ink is disposed on the rear side of the sheet main body 1. In addition, the colored layer 52 is disposed in a planar manner along the planar sheet body 1. The colored ink having translucency may be a printing ink having a color and having translucency, and may include a colorless and transparent ink. The thickness of the colored layer 52 is preferably in the range of about 1 to 20 μm, but can be changed as appropriate. The colored layer 52 gives a color to the front side of the decorative sheet 51 and provides visual representation of characters, figures, patterns, etc., and is printed once or plural times by applying the conventional printing technology. As a result, a colored layer 52 is formed by a monochrome or multicolor printing layer.

The colored layer 52 may include a first colored area 53 in which a thickened portion 56 described later is not disposed on the rear side, and a second colored area 54 in which the thickened portion 56 is disposed on the rear side. The first colored area 53 and the second colored area 54 may be colored in different colors that differ in at least one of hue, lightness, and saturation. The colored layer 52 including the first colored area 53 and the second colored area 54 is not limited to one color, and plural colors may be used.

The colored layer 52 is to transmit light input to and output from the metallic reflective layer 57 described later to the viewer in front, using a colored ink having translucency. It is also possible to use an ink having no light property, and for example, in the case where it is desired to mix a metallic glossy part and a non-metallic part from the viewpoint of enhancing the decorative effect, or a device etc. For this reason, it is possible to use an ink which does not transmit light partially.

(About thick portion 56)
The translucent thickened portion 56 is disposed at a position including the rear surface of at least a part of the colored layer 52 and protrudes rearward from the rear surface side of the colored layer 52. The thickened portion 56 having translucency is formed of a thick ink made of a synthetic resin such as an epoxy resin, an acrylic resin, a urethane resin, a mixture or a compound thereof, and has translucency. If it is, it may be transparent or may be colored with a pigment or the like as in the colored ink.

The thickness (t) of the thickened portion 56 is preferably 75 μm or more, and more preferably 80 μm or more, because the thickness (t) and the width (l) of the thickened portion 56 greatly affect the decorative effect of the decorative sheet 51. preferable. This thickness (t) can enhance the three-dimensional decorative effect as it is increased, but as it becomes larger, its accuracy maintenance and mass production become difficult, and there is a limitation on usable materials, so 150 μm or less Is suitable and less than 100 .mu.m is more stable, but does not prevent implementation at a thickness greater than 150 .mu.m. The width (l) is suitably 0.3 mm to 3 mm to enhance the sharp decorative effect. However, since it is determined by the figure and character to be drawn, when metallic reflection and a three-dimensional decoration effect are obtained in a large area, it does not restrict to this. The width of the thickened portion 56 refers to the width of the base end side of the thickened portion 56 disposed on the rear surface side of the colored layer 52, as shown in FIG. 1 (F).
Although the decorative effect is flat in the case of only the colored layer 52 and the metallic reflective layer 57, the three-dimensional decorative effect can be enhanced by arranging the thick portion 56.

(Regarding the metallic reflective layer 57)
The metallic reflective layer 57 may include a reflective foil such as a metal foil or a hologram foil, and is disposed on the rear surface of at least a portion of the thickened portion 56. The metallic reflective layer 57 provides specular reflection and metallic gloss.

The metallic reflective layer 57 is preferably formed by transferring a reflective foil such as a metal foil or a hologram foil by a transfer foil method. The metallic reflective layer 57 may be formed by silk printing (silver paste ink or mirror ink), hot stamping, vapor deposition, or sputtering, but using a transfer foil provides a higher metallic reflective effect. It is advantageous in point. More specifically, transfer foil is advantageous in that transfer foil has higher specularity than silk printing (silver paste ink and mirror ink), and it is possible to use hologram foil which can not be made for silk printing. is there. When the metallic reflective layer 57 is formed by using a transfer foil method, a transfer binder layer (not shown) may be formed. The binder layer may be any one that fixes the reflective foil, and can be formed of, for example, transparent silk ink. In particular, it is appropriate to use an ink that does not cause cracking or cracking of the binder layer due to aging. The thickness of the metallic reflective layer 57 may be changed as appropriate, but is preferably in the range of about 0.03 to 0.05 μm.

(About metallic concave curved reflective surface 59)
As described above, the thickened portion 56 is disposed at a position including the rear surface of at least a part of the colored layer 52, and protrudes rearward from the rear surface side of the colored layer 52. Further, at least the periphery of the thickened portion 56 protruding rearward from the rear surface side of the colored layer 52 is a concave portion 58 curved toward the rear in a cross section in the thickness direction of the sheet main body 1 by surface tension. Equipped with A metallic reflective layer 57 is disposed on the rear surface of at least a part of the concave curved portion 58, and the metallic reflective layer 57 constitutes a metallic concave curved reflective surface 59. Therefore, the metallic concave curved reflecting surface 59 is a surface which is curved toward the rear in the cross section in the thickness direction of the sheet main body 1. The metallic reflective layer 57 may be disposed on the rear surface of at least a part of the concave curved portion 58 as described above (for example, as shown in FIG. 1 (B) (E)). It may be disposed on the rear surface of at least a portion of the concave curved portion 58 and the rear surface of at least a portion of the colored layer 52 adjacent to the thickened portion 56 (for example, FIG. 1 (A) (D)) (C) (F).

When the decorative sheet 51 is viewed from the front, the reflected light from the metallic concave curved reflective surface 59 can be visually recognized, but the metallic reflective layer 57 is at least the thickened portion 56 protruding rearward from the rear surface side of the colored layer 52. Since it is disposed on a part of the rear surface, the reflected light from the metallic concave reflective surface 59 is viewed with a sense of depth.

Further, the metallic reflective layer 57 is disposed on the rear surface of at least a part of the concave curved portion 58 to form a concave mirror-like reflective surface, and when the decorative sheet 51 is viewed from the front, metal Since the depth to the metallic concave reflective surface 59 changes as the position on the planar concave reflective surface 59 changes, in various directions from the metallic concave reflective surface 59 according to this change. The reflected light is visually recognized, and the change in the position of the viewer changes the location where the reflected light can be seen.

Furthermore, a region having a metallic reflection effect colored with the decorative sheet 51 in which the thickened portion 56 and the metallic reflective layer 57 are disposed on the rear side, and the thickened portion 56 and the metallic reflective layer 57 on the rear side. The decorative sheet 51 which is not disposed can be different in metallic reflection from the flat area having no metallic reflection effect, and a difference occurs in the decorative expression.

The first colored area 53 in which the thickened portion 56 is not disposed on the rear side and the second colored area 54 in which the thickened portion 56 is disposed on the rear side are at least one of hue, lightness, and saturation. When the coloring is performed in a different color, the thickened portion 56 and the metallic reflective layer 57 are not disposed on the rear surface side, and the thickened portion 56 and the flat region having no metallic reflection effect in the decorative sheet 51. The difference in decorative expression from the area having the metallic reflection effect colored by the decorative sheet 51 on the rear surface side of the metallic reflection layer 57 is further emphasized, and the three-dimensional decoration effect can be further enhanced.
From the above, the decorative sheet 51 can be made to exhibit a new decorative effect by configuring the thickened portion 56 and the metallic reflective layer 57 as described above.

In the second colored region 54, the thick portion 56, and the metallic reflective layer 57, the thick portion 56 is disposed on the rear surface side of the second colored region 54, and the metallic reflective layer 57 is at least a part of the concave portion 58. When the decorative sheet 51 is viewed from the front, the outer edges of the three members (peripheral lines in plan view) may not substantially coincide with each other as long as they are disposed on the rear surface, and may be shifted in plan view. As an example in which the outer edges of these three are deviated in plan view, the metallic reflective layer 57 may be disposed on the rear surface of a part of the concave curved portion 58 or the second colored area 54 may be a proximal end of the thickened portion 56 Although the case where it forms over the width | variety of a side is mentioned, there exist various how to shift | deviate.

When the decorative sheet 51 is viewed from the front, it is desirable that the outer edges of these three members be substantially coincident, and it is most desirable that the outer edges of these three members be completely coincident, but they are not completely coincident. In any case, when the decorative sheet 51 is viewed from the front, if only the second colored area 54 is recognized as emitting light with metallic reflection, it can be said that they are substantially identical. It does not have to be a perfect match. In this case, more specifically, it is preferable that the displacement in plan view of the outer edge (peripheral line) of the three is within 3 mm, and more preferably within 1 mm. When the decorative sheet 51 is viewed from the front, the outer edges of the three parts substantially coincide with each other, whereby the entire second colored area 54, the thickened portion 56, and the metallic reflective layer 57 have a metallic reflection effect. be able to.

The colored layer 52, the thickened portion 56, and the metallic reflective layer 57 are preferably disposed on the rear surface side of the sheet main body 1, but if the decorative sheet 51 is a laminate of a plurality of layers, it is disposed between the layers. I don't care. The colored layer 52, the thickened portion 56, and the metallic reflective layer 57 are for displaying various patterns and characters such as illustrations and photographs on the front surface of the decorative sheet 51.

(About adjustment layer 2)
Moreover, the decoration sheet 51 may arrange the adjustment layer 2 in the back surface. The color of the adjustment layer 2 does not matter. It may be transparent, or may be colored with a pigment or the like, as with the colored ink. The adjustment layer 2 is composed of a layer of a pressure-sensitive adhesive or an adhesive and a resin film such as a polyethylene terephthalate resin or a polycarbonate resin disposed on the rear surface. When forming the decorating goods 72 provided with the decorating sheet 51 which is mentioned later, it is desirable to arrange the adjustment layer 2 in the back surface of the decorating sheet 51. As shown in FIG. By arranging the adjustment layer 2 on the rearmost surface of the decorative sheet 51, the color flow of the object to be decorated 71 can be suppressed. In addition to coating with a coater, offset printing or silk printing can be used to form the adjustment layer 2. By forming the adjustment layer 2, the unevenness on the rear surface of the decorative sheet 51 (the unevenness due to the presence or absence of the thick portion 56 of the decorative sheet 51) is alleviated, and the smoothness of the front surface of the decorative sheet 51 is maintained. Moreover, it prevents that the unevenness | corrugation of the back surface of the decoration sheet 51 comes out to the front surface by a time-dependent change. In addition, pinholes in the reflective foil can be made less noticeable. The adjustment layer 2 may be disposed on the rearmost surface of the decorative sheet 51. However, by disposing the adjustment layer 2 only on the portion where the thickened portion 56 does not exist, the relief may be more effectively alleviated.

The adjustment layer 2 and the adhesive or adhesive described later can also alleviate the unevenness on the back surface of the decorative sheet 51 (the unevenness due to the presence or absence of the thickened portion 56 of the decorative sheet 51), and the decorative sheet The difference in height of irregularities on the back surface of the adhesive 51 or adhesive 51 can be made smaller than the difference in irregularities due to the thickened portion 56, and the adjustment layer 2 and the adhesive or adhesive are used in combination It is also possible.

(About the smoothness of the surface)
In this embodiment, since the surface of the decoration sheet 51 is smooth, it is not necessary to arrange a smooth sheet whose surface is separate. Also, as described later, when the decorative sheet 51 is attached to the object to be decorated 71 to form the decorative item 72, it is conceivable that the unevenness of the rear surface affects the smoothness on the surface side due to the temporal change. As described above, by reducing the unevenness of the rear surface of the decorative sheet 51, it is possible to suppress the occurrence of the influence of the smoothness.

The decorative sheet 51 according to this embodiment has a high degree of freedom in selecting materials, such as a sheet having heat resistance that can withstand high temperatures of 135 ° C. For example, the decorative resin sheet described in Patent Document 3 needs to be vacuum molded in order to form a convexity for decoration on the front surface, and the heat resistance of the sheet is required to improve its formability. Although a limitation has occurred, the decorative sheet 51 according to this embodiment can adopt a general sheet used for a printing sheet, and provide the decorative sheet 51 with high quality stability. it can.

An enlarged photograph from the front of the decorative sheet 51 according to the first embodiment of the present invention is shown in FIG. 2 (A), and an enlarged view from the front of the decorative resin sheet after the forming step of Patent Document 3 is shown in FIG. The photograph is an enlarged photograph from the front of the sheet in which the colored layer 52 is disposed on the back surface of the sheet main body 1 in FIG. 2C and the metallic reflective layer 57 of transfer foil is disposed on the entire back surface side of the colored layer 52. Show.

In FIG. 2A, while maintaining the smoothness of the front surface, the three-dimensional decorative effect is enhanced by the metallic reflection effect of the thickened portion 56 and the metallic reflective layer 57 protruding rearward from the rear surface side. It is a thing. In particular, the mesh-like portion is used as the second colored region 54, and the thick portion 56 and the metallic reflective layer 57 are disposed only on the rear surface of the second colored region 54, thereby forming another portion (first The contrast with the colored region 53) is clear, and the three-dimensional effect of the mesh-like second colored region 54 is enhanced.

In FIG. 2 (B), the design of the first and second colored regions 54 is the same as in FIG. 2 (A), but the metallic reflective layer is on the front surface of the decorative convex portion having a three-dimensional bending surface By arranging 57 and the second colored region 54, the three-dimensional effect of the mesh-like second colored region 54 is enhanced.
In both cases, the three-dimensional appearance of the second colored region 54 is enhanced, but in FIG. 2 (A) the metallic reflective layer 57 is concave, while in FIG. 2 (B) the metallic reflective layer is The portion 57 strongly reflects the light from the light source in a metallic manner (although it is partially white in the photograph, even though the positional relationship with the light source (fluorescent lamp) is almost the same because 57 is a convex curved surface. The different parts) are different and express different three-dimensional effects.

Further, in FIG. 2C, the design of the first and second colored regions 54 is the same as FIG. 2A, but the metallic reflective layer 57 is disposed on the entire rear surface side of the colored layer 52. Since the thickened portion 56 does not exist, it is only possible to obtain a planar aesthetic appearance. Further, since the metallic reflective layer 57 is disposed on the entire surface, although the positional relationship with the light source (fluorescent lamp) is substantially the same as in FIGS. 2 (A) and 2 (B), FIG. There is no part which strongly reflects the light from the light source metallically as shown in (B), but the light source (fluorescent lamp) is reflected in a band.

(About the decoration sheet 51: 2nd embodiment)
Next, the decorative sheet 51 will be described with an eye toward the outer edge of the decorative portion 60 when the decorative sheet 51 is viewed in plan. The principal part expanded sectional view of the decoration sheet 51 which concerns on 1st Embodiment of this invention mentioned above to FIG. 3 (A) is shown, FIG. 3 (B) shows the decoration sheet 51 which concerns on 2nd Embodiment of this invention The principal part enlarged sectional view is shown.
By giving the same code | symbol to the same member as the above-mentioned, detailed description is abbreviate | omitted.

The decorative sheet 51 according to the first embodiment of the present invention shown in FIG. 3 (A) has the colored layer 52, the thickened portion 56, and the metallic reflective layer 57 on the back surface side of the sheet main body 1 in that order. 3B, the decorative sheet 51 according to the second embodiment of the present invention shown in FIG. 3B has the thickened portion 56, the colored layer 52, and the metallic reflective layer 57 on the rear surface side of the sheet main body 1. The difference is that the three are arranged in that order. In other words, in the decorative sheet 51 according to the second embodiment of the present invention, the colored layer 52 is disposed on the rear surface side of the thickened portion 56 and the metallic reflective layer 57 is disposed on the rear surface side of the colored layer 52. is there. Even in the second embodiment, the metallic reflective layer 57 forms the metallic concave reflective surface 59, and the reflected light passes through the colored layer 52 and further through the thickened portion 56 and the sheet main body 1. The three-dimensional decorative effect is exhibited by reaching the eyes of the viewer ahead. However, the second embodiment is different from the first embodiment in that there is no change in the distance in the thickness direction between the colored layer 52 and the metallic reflective layer 57.

(Relationship between Region in Colored Layer 52, Thickened Portion 56, and Metallic Reflective Layer 57)
In any of the embodiments, in order to make the viewer in front of the user visually perceive the three-dimensional decorative effect from the metallic concave reflection surface 59, another region (first A second colored area 54 of a color different from the colored area 53) is provided, and outer edges (peripheral lines in plan view) of the third colored area 54, the thickened portion 56, and the metallic reflective layer 57 are It is preferable to have the outer edge matching portions substantially coincident with each other. As a result, only the area (second colored area 54) that is distinguished from the other areas (first colored area 53) in color gives a three-dimensional impression, and the expression represented by the second colored area 54 is , You can make a sharp and strong impression on the viewer ahead.

More specifically, in the example of FIG. 2A, the mesh-like portion is the second colored region 54, and the thick portion 56 and the metallic reflective layer 57 are disposed only in that portion. The contrast with the other part (first colored area 53) is clear, and the three-dimensional decoration effect can be enhanced as a whole.

As described above, the colored layer 52 includes the first colored area 53 in the position where the thickened portion 56 does not exist and the second colored area 54 in the position where the thickened portion 56 exists, as viewed from the front. Preferably, the first colored area 53 and the second colored area 54 are colored in different colors that differ in at least one of hue, lightness, and saturation.

In other words, when the decorative sheet 51 is viewed from the front, the thickened portion 56, the second colored region 54, and the metallic reflective layer 57 have substantially the same outer edges (peripheral lines in plan view). It shall be. Most desirably, as described above, although the outer edges of the three are completely coincident, when the decorative sheet 51 is viewed from the front without being completely coincident, only the second colored region 54 is metallic. If it is recognized as emitting light accompanied by reflection, it can be said to be substantially coincident, and it is not necessary to be completely coincident. More specifically, it is preferable that the displacement in plan view of the outer edge (peripheral line) of the three is within 3 mm, and more preferably within 1 mm.

As mentioned above, the metallic part colored with the decoration sheet 51 by which the decorative part 60 comprised from three layers of the thick part 56, the 2nd colored area 54, and the metallic reflective layer 57 was arranged at the back side. In the area having a reflection effect, and in the flat area having no metallic reflection effect by the decorative sheet 51 in which the decorative portion 60 formed of one layer of the first colored area 53 is disposed on the rear surface side, color (Hue, lightness, saturation) and metallic reflection can be different, and different decorative expressions are exhibited, so the decorative sheet 51 according to the present invention in which these are combined has a distinctive decorative effect Can be demonstrated. By configuring the decorative portion 60 as described above, the decorative sheet 51 can exhibit a new decorative effect.

Further, the configuration of the decorative portion 60 is arranged from the front in the thickness direction to the second colored region 54-the thickened portion 56-the metallic reflective layer 57, and between the second colored region 54 and the metallic reflective layer 57. In the structure of the first embodiment, the thickened portion 56 is disposed with the thickened portion 56-the second colored area 54-the metallic reflective layer 57, and the metal on the back surface of the second colored area 54 In the configuration in which the objective reflective layer 57 is disposed, that is, the configuration of the second embodiment, it is considered that the reflected light from the metallic reflective layer 57 transmitted through the colored layer 52, which the viewer in front sees, is different. Therefore, it is expected that various decorative effects will be expressed.

Of course, from the point of enhancing the decorative effect, it does not prevent the three parties from intentionally providing an area where they do not coincide, to perform effective decoration as a whole. Specifically, the first colored area 53, the thickened portion 56, the area where the metallic reflective layer 57 is in agreement, the area including the second colored area 54 and the metallic reflective layer 57, and only the metallic reflective layer 57 It can be implemented by combining various layers and regions, such as a region where the thick portion 56 and the metallic reflective layer 57 are formed.

The binder layer may be any one that fixes the reflective foil, and can be formed of, for example, transparent silk ink. In particular, it is appropriate to use an ink that does not cause cracking or cracking of the binder layer due to aging.

(Details when metal transfer foil is used for metallic reflective layer)
The case of using a metal transfer foil such as a metal foil or a hologram foil as the metal reflective layer 57 will be described in more detail with reference to FIG. The metal transfer foil is industrially supplied as a transfer sheet (not shown), and the basic structure thereof is a release layer, a surface protection layer optionally laminated, and a coloring on a carrier film. It is a laminated body in which layers such as a layer, a hologram layer, a metal layer, and an adhesive layer are sequentially laminated.

As the metal layer, aluminum is used in the case of a normal metal foil, or transparent titanium oxide or the like is used in the case of a hologram, and this is implemented as a light reflective layer of various configurations. Although various modifications may be made, such as being omitted depending on the color required also for the colored layer, the basic configuration is a peeling layer (carrier film, release layer, etc.) removed at the time of fixing. It is provided with a metallic layer 42 (a surface protective layer, a layer in which a colored layer and a hologram layer are selectively laminated if necessary), and an adhesive layer 41 such as a hot melt adhesive. The transfer sheet is transferred with energy such as heating and pressure applied with the adhesive layer 41 in contact with the surface of the object, and the adhesive layer 41 and the metallic layer 42 are formed on the surface of the object. By being left, the decoration in which the adhesive layer 41 and the metallic layer 42 are laminated is applied to the surface of the object.

In the application to the present invention, the transparent adhesive layer 41 and the metallic layer 42 as the metallic reflective layer 57 are disposed and laminated on the rear surface of the thickened portion 56, and the adhesive layer 41 and the metallic layer are formed on other portions. 42 is not stacked.
As a specific example, as shown in FIG. 4A, the thickened portion 56 is made of only the transparent fixing ink, and the transparent fixing ink and the adhesive layer 41 are adhered to each other to form the metallic layer 42. Can be fixed to the rear surface of the thickened portion 56 through the adhesive layer 41. At that time, the first colored area 53 in the outer peripheral area of the thickened portion 56 is adhered to the back surface of the second colored area 54 and the thickened portion 56 by using a non-fixing ink which is not adhered by the adhesive layer 41. The agent layer 41 and the metallic layer 42 are not fixed. In processing using a general transfer sheet, the transparent fixing ink is applied for the purpose of fixing with the adhesive layer 41, and its thickness is as small as possible (specifically, several μm). In this embodiment, it is desirable that the transparent fixing ink has a thickness of several tens of μm, more preferably 30 μm or more, and the thick portion 56 by one or more thick printings. It forms.

In order to enhance the adhesion between the transparent fixing ink of the thick portion 56 and the adhesive layer 41 to realize good fixing, resin components used in the transparent fixing ink and the adhesive layer 41 contain the same resin component. However, it can be adjusted by the contained auxiliary components and auxiliary agents. On the other hand, in the first colored area 53, it is necessary to adopt a non-fixing ink using a transparent fixing ink and a resin component different from that of the adhesive layer 41 so as not to adhere to the adhesive layer 41. .
Although the adhesion between the transparent fixing ink and the adhesive layer 41 does not matter for the second colored area 54, it is preferable to use an ink having a good fixing property with the thick portion 56.

Also, as shown in FIG. 4B, after printing the transparent non-fixing ink 43 having no fixability with the adhesive layer 41 on the back surface of the first colored area 53 and the second colored area 54, 56 can be formed by printing with a transparent fixing ink, but although not shown, when forming the thick portion 56 by printing a plurality of times, at least only the rear surface is printed with a transparent fixing ink. There is no hindrance to forming it. However, as shown in FIG. 4A, it is preferable to reduce the number of layers to be formed as much as possible from the viewpoint of obtaining a good reflection effect as well as the point of manufacturing cost. The example shown in FIG. 4 can be implemented in combination with each of the embodiments shown in FIGS. 1 to 3. For example, as shown in FIG. It is also possible to constitute the colored layer 52 solely.
