Description

  The present invention relates to a three-dimensional printed material in which characters and the like can be seen three-dimensionally.

  Conventionally, characters, figures, symbols, etc. (abbreviated as “characters etc.” in this specification) printed on a base material are shown three-dimensionally (as if they are lifted), and the appearance design (design) is improved. Enhanced three-dimensional printed materials are being studied. As this kind of three-dimensional printed material, for example, those described in Patent Documents 1 and 2 are known.

The three-dimensional printed material described in Patent Document 1 includes a transparent base material layer (base material) provided on the outermost surface, a graphic expression layer disposed on the back surface of the transparent base material layer, and a peripheral edge of the graphic expression layer. An arranged transparent edge layer (edge layer), a light-shielding underlayer that contains light-reflective fine powder and covers the graphic representation layer and the transparent edge layer, and a backing layer arranged on the back of the light-shielding underlayer And.
The graphical representation layer can be configured, for example, by arranging a colored transparent ink layer on the side close to the transparent base material layer, and placing an uncolored transparent ink layer on the back side. The thickness of the transparent edge layer is thicker than the thickness of the graphic representation layer.

  When the three-dimensional printed material configured in this way is observed from the surface side of the transparent base material layer, the image representation layer surrounded by the light-shielding underlayer is light-shielding due to the difference in light reflection characteristics from the light-shielding underlayer. It seems to have lifted from the strata. Furthermore, the presence of a transparent edge layer at the boundary between the image representation layer and the light-shielding underlayer allows light incident from the surface side of the transparent base layer to be reflected in a complex manner in the transparent edge layer. After diffusing, it goes out to the surface side of the transparent substrate layer. The way the light of the transparent edge layer is reflected is greatly different from that of the graphic representation layer and the light-shielding underlayer, so that the graphic representation layer rises greatly and the stereoscopic effect is emphasized and observed.

On the other hand, the three-dimensional printed material described in Patent Document 2 is a plate-like or sheet-like base material, a ground color layer provided on the back side of the base material, and a design portion formed as an opening, and a ground color layer Covers both the narrow border layer (edge layer) formed in close contact with the side edge over the entire side edge of the design portion, and the back surface of the base material and the side edge and back surface of the border layer overlapping the design portion. And a shielding layer (backing layer) provided on the back side of the substrate so as to cover the ground color layer and the light reflecting layer.
In the three-dimensional printed material configured in this way, since the border layer is interposed between the light reflection layer and the ground color layer, the light reflection layer in the design portion is visually recognized as protruding from the ground color layer. The

  However, in the three-dimensional printed material, there are various demands for adjusting the brightness of light reflected by the three-dimensional printed material and the transparency of the transparent member according to the specification of the attachment object to which the three-dimensional printed material is attached. For example, when the thickness of the three-dimensional printed material is reduced, characters and the like are hardly seen three-dimensionally.

  The present invention has been made in view of such problems, and it is an object of the present invention to provide a three-dimensional printed material in which the brightness and the like of reflected light can be easily adjusted and characters and the like can be seen more three-dimensionally.

Hereinafter, an embodiment of a three-dimensional printed material according to the present invention will be described with reference to FIGS. 1 to 6.
As shown in FIGS. 1 and 2, the three-dimensional printed material 1 according to the present embodiment is laminated on a base material 10 formed in a sheet shape and one surface 10 a of the base material 10, and the thickness direction D of the base material 10. A ground color layer 15 provided with a cutout portion (opening) 16 penetrating into the ground color layer, a flat surface laminated in the cutout portion 16 of the ground color layer 15, and a surface 15 a opposite to the base material 10 in the ground color layer 15. The first edge layer 25, the second edge layer 26, and the first edge layer 25 laminated on the surface 20 a of the planarizing layer 20 opposite to the base material 10. Between the second edge layer 26, a part of the surface 25a opposite to the planarization layer 20 of the first edge layer 25, and the planarization layer 20 of the second edge layer 26 And a light reflecting layer 30 laminated on a part of the opposite surface 26a.
FIG. 2 is a cross-sectional configuration of a range R1 including characters and the like that appear three-dimensionally in the three-dimensional printed material 1. The effect that characters and the like look three-dimensional will be described later.

The base material 10 is made of a transparent material such as PC (polycarbonate resin), PMMA (polymethyl methacrylate resin), PET (polyethylene terephthalate resin). The base material 10 has a thickness (length in the thickness direction D) of, for example, 50 μm (micrometers) or more and 300 μm or less. It has been found that when the thickness of the substrate 10 is less than 50 μm, the substrate 10 loses elasticity (elasticity), and the workability and productivity at the time of printing and UV (ultraviolet) coating are remarkably impaired. The thickness of the substrate 10 is more preferably 75 μm or more and 200 μm or less.
In order to improve the adhesion between the UV layer including the UV texture layer 35 described later and the base material 10, an easy adhesion HC (hard coat), primer layer, or binder layer may be provided on the outer surface of the base material 10. preferable.

In the present embodiment, a UV texture layer (uneven layer) 35 is laminated between the base material 10 and the ground color layer 15. The UV texture layer 35 is formed over the entire surface of the one surface 10 a of the substrate 10. A plurality of convex portions 36 are formed on the surface of the UV texture layer 35 on the ground color layer 15 side. In this example, a so-called hairline 37 is formed by the plurality of convex portions 36.
In this example, the hairline 37 is formed by the plurality of convex portions 36, but a known texture such as a so-called spin, matte, carbon, or hologram shape can be formed by a plurality of convex portions other than the hairline 37.
The UV texture layer 35 is formed of a transparent UV curable resin. The thickness of the UV texture layer 35 is, for example, not less than 0.5 μm and not more than 20 μm, and more preferably not less than 1 μm and not more than 15 μm.

When the thickness of the UV texture layer 35 exceeds 20 μm, transparency of the UV texture layer 35 and workability when manufacturing the UV texture layer 35 are impaired. Further, the curing of the UV texture layer 35 does not proceed sufficiently, causing a problem that the pattern formed by the convex portions 36 disappears or becomes cloudy.
The convex portion 36 of the UV texture layer 35 can be formed by, for example, a transfer method.

  The ground color layer 15 is formed by printing or vapor deposition. The ground color layer 15 is preferably formed of an opaque, colored or colorless material. More preferably, the ground color layer 15 is formed of a reflective material. For example, a mirror ink can be used for the ground color layer 15. The ground color layer 15 serves as a background of the shadow of the UV texture layer 35 and characters and the like that appear three-dimensionally. The thickness of the ground color layer 15 is, for example, not less than 0.01 μm and not more than 20 μm, and more preferably not less than 0.05 μm and not more than 15 μm.

  The planarization layer 20 is formed of a transparent UV curable resin. The refractive index of the UV curable resin that forms the planarizing layer 20 and the refractive index of the UV curable resin that forms the UV texture layer 35 are preferably equal to or approximately equal to each other.

The thickness of the planarization layer 20 (the thickness of the portion laminated on the surface 15a of the ground color layer 15) is, for example, 0.1 μm or more and 20 μm or less. More preferably, it is 0.5 μm or more and 10 μm or less.
When the thickness of the planarizing layer 20 exceeds 20 μm, there arises a problem that the planarizing layer 20 impairs transparency or the planarizing layer 20 is curled.
The surface 20a of the planarization layer 20 is formed flat. In this example, the planarization layer 20 is formed over the entire surface of the one surface 10a of the substrate 10.
The planarizing layer 20 is in contact with the plurality of convex portions 36 in a range overlapping the punched portion 16 when viewed in the thickness direction D. As described above, the refractive index of the UV curable resin that forms the planarizing layer 20 and the refractive index of the UV curable resin that forms the UV texture layer 35 are equal to or substantially equal to each other. It becomes difficult for light to be refracted at the boundary with 20. For this reason, the plurality of convex portions 36 formed on the punched portion 16 of the UV texture layer 35 cannot be seen from the outside.

In the present embodiment, the light transmittance adjusting layer 40 is laminated between the first edge layer 25, the second edge layer 26, the light reflecting layer 30, and the planarization layer 20. The light transmittance adjusting layer 40 is formed of a material containing a transparent UV curable resin such as medium. The thickness of the light transmittance adjusting layer 40 is, for example, not less than 0.5 μm and not more than 20 μm. The light transmittance adjusting layer 40 preferably contains particles having light scattering properties such as silica (SiO ₂ ). The outer diameter of the particles is preferably 0.01 μm or more and 5 μm or less.
The light transmittance adjusting layer 40 is a layer that can be provided when it is desired to reduce the amount of light reflected from the light reflecting layer 30 from the viewpoint of design.

When viewed in the thickness direction D, the first edge layer 25 is laminated so as to overlap the first edge 16 a of the cutout portion 16 of the ground color layer 15. In this example, the first edge layer 25 is laminated up to a range overlapping the edge 15b of the ground color layer 15. The second edge layer 26 is laminated so as to overlap the second edge 16 b of the punched part 16. In this example, the second edge layer 26 is laminated to a range overlapping the edge 15c of the ground color layer 15. The first edge portion 16a and the second edge portion 16b of the extraction portion 16 are different edge portions of the extraction portion 16 in the cross section shown in FIG.
The edge layers 25 and 26 are configured by including particles having light scattering properties such as silica in a transparent UV curable resin. The thickness of the edge layers 25 and 26 is, for example, not less than 0.5 μm and not more than 20 μm, and preferably not less than 1 μm and not more than 15 μm. The content of the light scattering particles in the edge layers 25 and 26 is preferably 0.1% by weight or more and 20% by weight or less, and more preferably 0.5% by weight or more and 10% by weight or less. The outer diameter of the particles is preferably 0.01 μm or more and 5 μm or less.

  Thus, the UV texture layer 35, the planarization layer 20, the light transmittance adjustment layer 40, and the edge layers 25 and 26 are formed using a transparent UV curable resin. However, the UV curable resin that forms the UV texture layer 35, the planarizing layer 20, the light transmittance adjusting layer 40, and the edge layers 25 and 26 may have different physical properties such as viscosity.

The material used for the light reflecting layer 30 needs to have a luminance of the ground color layer 15 or higher. The light reflecting layer 30 can be formed by vapor deposition, sputtering, or printing. For the light reflecting layer 30, for example, mirror ink having higher reflectivity than the ground color layer 15 can be used. The reflectance of the ground color layer 15 region of the three-dimensional printed material 1 at a wavelength of 550 nm (nanometer) may be 20% or less, and the reflectance of the light reflection layer 30 region at a wavelength of 550 nm may be 40% or more.
The thickness of the light reflecting layer 30 (the thickness of the portion laminated on the surfaces 25a and 26a of the edge layers 25 and 26) is, for example, not less than 0.01 μm and not more than 20 μm. More preferably, it is 0.01 μm or more and 10 μm or less.

In the present embodiment, the three-dimensional printed material 1 includes a surface of the light reflecting layer 30 opposite to the planarizing layer 20, a first edge layer 25, a second edge layer 26, and a surface of the planarizing layer 20. A backing layer 45 is laminated to cover a portion 20a that is not covered with the light transmittance adjusting layer 40.
The backing layer 45 can be formed by printing an opaque ink having a high shielding property. The color of the backing layer 45 can be selected from black, gray, ivory, white, etc., and a monotone color is mainly used. The thickness of the backing layer 45 is not less than 0.5 μm and not more than 20 μm, for example. The backing layer 45 is formed so that the back surface of the three-dimensional printed material 1 is flat.
Since the three-dimensional printed material 1 includes the backing layer 45, the three-dimensional printed material 1 has a function of shielding light, and further, the appearance (appearance) of the three-dimensional printed material 1 is improved.

  The thickness (total thickness) of the three-dimensional printed material 1 as a whole is desirably 300 μm or less. If the thickness of the three-dimensional printed material 1 exceeds 300 μm, the transparency of the three-dimensional printed material 1 and the workability when manufacturing the three-dimensional printed material 1 are impaired.

  In FIG. 1, the cross-sectional configuration of the range R <b> 2 including the characters and the like that are seen in a plane of the three-dimensional printed material 1 is as shown in FIG. That is, in the range R2, the edge layers 25 and 26 are not formed for each component of the range R1.

In FIG. 1, the cross-sectional configuration of the range R3 including the window 50 of the three-dimensional printed material 1 is as shown in FIG. That is, the ground color layer 15 is formed with a second punched portion 17 penetrating in the thickness direction D. The first edge layer 25, the second edge layer 26, the light reflection layer 30, the light transmittance adjustment layer 40, and the backing layer 45 are in a range overlapping the second punched portion 17 in the thickness direction D. Not formed.
Since the UV texture layer 35 and the planarizing layer 20 are formed of UV curable resin having substantially the same refractive index, a plurality of convex portions 36 formed on the second punched portion 17 of the UV texture layer 35 are provided. It disappears from the outside. Therefore, the range where the second punched portion 17 is formed does not show the convex portion 36 of the UV texture layer 35 and functions as a transparent window portion 50 throughout the thickness of the three-dimensional printed material 1.

With respect to the three-dimensional printed material 1 configured as described above, for example, the operation when the user P sees the range R4 including the three-dimensionally visible characters shown in FIG. 1 from obliquely above as shown in FIG. 5 will be described. FIG. 5 shows a configuration in which the three-dimensional printed material 1 is not provided with the light transmittance adjusting layer 40.
Among the light L1 such as sunlight incident on the base material 10, the light L1 that has reached the second edge layer 26 in the range R6 on the second edge layer 26 side, which is the near side for the user P, Light is collected by the influence of the second edge layer 26. A part of the light L <b> 1 is affected by the light scattering particles contained in the second edge layer 26. Since the light reflecting layer 30 is laminated on a part of the surface 26a of the second edge layer 26, the light entering the second edge layer 26 is reflected toward the user P side. As shown in FIG. 6, the range R6 looks relatively bright to the user P.

  As shown in FIG. 5, in this embodiment, the distance M from the surface of the substrate 10 to the edge layers 25 and 26 is longer than that in the case where the planarizing layer 20 is not provided. For this reason, the angle range of the light which can enter into the 2nd edge layer 26 spreads, and the quantity of the light which contributes to scattering increases.

On the other hand, as shown in FIG. 5, the light L <b> 1 that has reached the first edge layer 25 in the range R <b> 7 on the first edge layer 25 side that is the back side for the user P is the first edge layer 25. Scattered by the influence of. As shown in FIG. 6, the range R7 looks relatively dark to the user P.
As shown in FIG. 5, the light L1 that has reached the light reflecting layer 30 in the range R8 between the range R6 and the range R7 is simply reflected by the light reflecting layer 30 without being affected by the edge layers 25 and 26. Is done. As shown in FIG. 6, the light reflected in the range R8 appears to the user P as an intermediate brightness between the brightness of the light reflected in the range R6 and the brightness of the light reflected in the range R7.
Thus, there is a range R6 that appears brighter than the range R8 on one side of the range R8 across the range R8, and a range R7 that appears darker than the range R8 on the other side of the range R8. That is, the range R6, the range R8, and the range R7 are arranged in descending order of the amount of light, so that the characters in the range R4 can be seen three-dimensionally.

  In addition, when the user P sees the range R4 from the front, the range R8 looks brighter than the ranges R6 and R7.

  When the range R6 or the range R8 looks too bright, the light transmittance adjustment layer 40 adjusts. At this time, since the surface 20a of the planarizing layer 20 is formed flat, design elements of the shapes of the light transmittance adjusting layer 40, the edge layers 25 and 26, and the light reflecting layer 30 are reduced. By reducing the number of design elements, the parameters of the light transmittance adjusting layer 40, the edge layers 25 and 26, and the light reflecting layer 30 can be easily and reliably adjusted.

  On the other hand, in the configuration of the range R2 shown in FIG. 3, since there is no portion that looks bright or dark like the ranges R6 and R8 described above, characters and the like look planar.

As described above, according to the three-dimensional printed material 1 of the present embodiment, since the planarizing layer 20 is provided, it is possible to easily adjust parameters such as the brightness of light reflected by the light reflecting layer 30. As the distance M increases and the amount of light contributing to scattering increases, characters and the like appear more three-dimensional.
The planarizing layer 20 is in contact with the plurality of convex portions 36 of the UV texture layer 35 in a range overlapping the punched portion 16. Therefore, even if the UV texture layer 35 is formed in a range overlapping the punched portion 16 when viewed in the thickness direction D, the hairline 37 cannot be seen in the punched portion 16.
The UV texture layer 35 can impart design properties to the three-dimensional printed material 1.

A light transmittance adjusting layer 40 is provided between the edge layers 25 and 26 and the light reflecting layer 30 and the planarizing layer 20, and the transparency and reflectance of the light transmittance adjusting layer 40 are adjusted. Thereby, the brightness | luminance of the light reflected from the three-dimensional printed matter 1 can be adjusted easily and reliably.
In the range where the second punching portion 17 is formed in the ground color layer 15 and overlaps the second punching portion 17 in the thickness direction D, the edge layer layers 25 and 26, the light reflecting layer 30, and the light transmittance adjusting layer 40. , And the backing layer 45 is not formed. Therefore, the range in which the second punched portion 17 is formed can be a transparent window portion 50 over the entire thickness of the three-dimensional printed material 1.

By configuring the three-dimensional printed material 1 in this way, a three-dimensionally visible shape can be formed in a single substrate 10 formed of PC, PMMA or the like.
By using the three-dimensional printed material 1 of the present embodiment, an unprecedented design can be formed on a molded product such as In-Mold Labeling.
The design of the three-dimensional printed material can be improved by glossing the surface of the three-dimensional printed material and forming a texture layer on the back surface.
Two or more kinds of textures such as spin and mat and two or more windows can be freely formed on the three-dimensional printed material.

By using the three-dimensional printed material together with resin molding, or pasting the three-dimensional printed material on transparent or opaque material members such as PC, PMMA, composite board, glass, metal, etc., white / black appliances, luxury containers, electricity It can be used for panels of equipment, nameplates, etc. to improve the design of all fields and industries.
As described above, the application and field of the three-dimensional printed material can be expanded not only to the electric equipment, but can be applied and developed to high-end products and commercial materials with high design properties.
The three-dimensional printed material of the present embodiment is very suitable for design applications in which the thickness of the external decoration is limited. That is, it is suitable for a design in which a high-class feeling is desired in which characters and the like are seen three-dimensionally with a relatively flat configuration with a thickness of 300 μm or less.

Even if the UV texture layer 35 is formed over the entire surface of the one surface 10a of the substrate 10, the flattened layer 20 can form the cutout portion 16 and the window portion 50 in a transparent manner, so that it matches the shape of the cutout portion 16 and the window portion 50. Therefore, it is not necessary to prepare a mold for forming the UV texture layer 35.
For this reason, the cost of the mold for forming the UV texture layer 35 can be suppressed, and the tact time and lead time can be shortened.

As mentioned above, although one embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment, and modifications, combinations, and deletions within a scope that does not depart from the gist of the present invention. Etc. are also included.
For example, in the above embodiment, the light reflecting layer 30 is formed on a part of the surface 25a of the first edge layer 25. However, the light reflecting layer 30 is the entire surface 25a of the first edge layer 25. It may be formed. The same applies to the surface 26a of the second edge layer 26.

The first edge layer 25 may be laminated only in a range that overlaps the first edge 16a of the punched part 16 when viewed in the thickness direction D. The same applies to the second edge layer 26.
The three-dimensional printed material 1 may not include the light transmittance adjusting layer 40, the backing layer 45, and the window portion 50.
