Description

  The present invention relates to a decorative body in which a printed design looks different depending on a viewing angle.

  Conventionally, a technique has been proposed in which a decorative pattern attached to a decorative surface of a decorative body looks different depending on the viewing angle. For example, as disclosed in Patent Document 1, “a first layer that is printed on the surface of a printing object and that constitutes a predetermined first design, and a predetermined layer that is printed on the surface of the first layer. A plurality of second printing elements spaced apart and a shielding element printed on the surface of the second printing element for obscuring the surface, by the plurality of second printing elements When the second design is configured and viewed from the direction of the normal of the surface of the shielding element, the first design is visually recognized and when viewed from the direction inclined with respect to the normal of the surface of the shielding element, A partial laminate printed body is disclosed in which the first design and the second design are combined, or the second design is visually recognized.

  For example, in Patent Document 2, “Since a surface design layer formed of a transparent ink is provided on a base material, the surface design layer was hit depending on the angle at which the laminate was viewed or the angle of light hitting the laminate. The method of reflecting light changes, and the design and impression of the laminate change greatly. ”A laminate is disclosed.

JP 2010-247460 A JP 2014-100811 A

  In the partially laminated printed body disclosed in Patent Document 1, the printing elements are laminated, and the second design constituted by the second printing elements is visible only when viewed from a direction inclined with respect to the normal direction. In order to do so, it has a second printing element under the shielding element. Therefore, when viewed from the normal direction of the surface of the shielding element, the first design constituted by the shielding element is visually recognized, so that the design constituted by the printing element on the surface is not visually recognized or There is a problem that it is difficult to hide the design so that it is difficult to be visually recognized.

  Further, in the laminate disclosed in Patent Document 2, a surface design layer formed of a transparent ink is disposed on a base material, but a plurality of convex portions constituting the surface design layer are disposed. The arrangement in the direction parallel to the surface of the material is not specified, and the way the light is reflected by the transparent ink on the base material is different. That is, it is not intended to prevent the design on the surface of the base material from being visually recognized or to prevent the design from being visually recognized.

  The present invention has been made to solve the above-described problems, and when the surface of the decorative body is viewed from a certain angle, the decorative pattern applied to the surface is not visible or difficult to be visually recognized. The present invention provides a decorative body that can be viewed from a certain angle.

The decorative body according to the present invention includes a base material and a plurality of printing elements printed on the surface of the base material, and the printing element is visible to the naked eye when viewed from the vertical direction of the surface of the base material. The printing area is a size that cannot be visually recognized and is provided on the surface of the base material so that a plurality of the printing elements are gathered to form a decorative pattern. The printing element is smaller than the area of the ground surface where the printing element is not arranged, and the decorative pattern is configured to be invisible when viewed from the vertical direction of the surface of the base material, with respect to the vertical direction of the surface of the base material. when viewed from the direction inclined Te, the surface of the substrate overlap a plurality of the print elements so as not to be visible directly between the printing element, wherein the decorative pattern is visible.

  According to the present invention, when the surface of the decorative body is viewed from the front without laminating printing elements, the decorative pattern by printing is difficult to see or cannot be visually recognized, and when viewed from an oblique direction, the decorative pattern is not visible. Can be visually recognized, and a decorative body with a decorative pattern that changes depending on the viewing angle can be provided.

It is a schematic diagram which shows an example of the cross section of the decoration body in Embodiment 1 of this invention. It is the schematic diagram seen from the perpendicular direction of the surface of a decoration body in Embodiment 1 of this invention. It is a schematic diagram when the surface of the decorative body is seen obliquely from the direction of the hollow arrow 30 shown in FIG. FIG. 3 is a diagram when the vertical distance of printing elements is set to 0 with respect to FIG. 2. It is a schematic diagram when the surface of a decoration body is seen diagonally from the direction of the white arrow shown by FIG.

[Embodiment 1]
FIG. 1 is a schematic diagram showing an example of a cross section of a decorative body 1 in Embodiment 1 of the present invention. As shown in FIG. 1, the decorative body 1 according to Embodiment 1 of the present invention includes a base material 2 and a printing element 4. The surface of the decorative body 1 has a printing area 10 with the printing elements 4 and a non-printing area 20 without the printing elements 4.

<Substrate 2>
The base material 2 is comprised with resin, such as a metal and a plastic, gypsum, wood, etc. Moreover, the base material 2 may have not only a planar shape but a curved surface, and may have flexibility or flexibility. The surface 2 of the base material 2 is, for example, matte. The method of matting the surface is not particularly limited, and the surface 3 is finished to have a non-glossy surface by making the surface 3 uneven. For example, in resin molding, the mold may be embossed and transferred to a molded product, or a matte paint may be applied to the surface of the substrate 2. In addition, the base material 2 does not need the surface 3 to be matted, and may have gloss.

<Printing element 4>
A printing element 4 is provided by printing on the surface 3 of the substrate 2. A plurality of printing elements 4 are provided so as to form a predetermined decorative pattern. An area on the surface 3 of the substrate 2 on which the printing element 4 is provided is called a printing area 10, and an area on which the printing element 4 is not provided is called a non-printing area 20. The plurality of printing elements 4 provided on the surface 3 of the substrate 2 have a rectangular cross section, for example, as shown in FIG. The plurality of printing elements 4 are arranged with a predetermined distance L, and the surface of the substrate 2 between the plurality of printing elements 4 in the printing region 10 is particularly referred to as a ground surface 5.

  In the first embodiment, the ink or paint constituting the printing element 4 is, for example, transparent, and may be colorless and transparent or colored and transparent. Further, the surface of the printing element 4 may be glossy or matt. In the first embodiment, the ink or paint is transparent, but non-transparent may be used. Printing on the front surface 3 is not particularly limited, and may be a printing method such as pad printing, ink jet printing, or screen printing. After printing, the ink or paint constituting the printing element 4 is fixed by heating, UV irradiation, or the fixing action by the composition of the ink or paint itself.

  FIG. 2 is a schematic diagram viewed from the vertical direction of the surface 3 of the decorative body 1 in the first embodiment of the present invention. The sizes of the printing elements 4 are a horizontal dimension A and a vertical dimension B in FIG. FIG. 2 is an enlarged schematic view of the surface 3 of the decorative body 1, so that each printing element 4 is shown in a visible size, but the actual decorative body 1 is arranged in a direction perpendicular to the surface 3. When viewed from the side, each printing element 4 is set to have a horizontal dimension A and a vertical dimension B that cannot be visually recognized even if a normal person holds it in the hand and observes it with the naked eye. The horizontal dimension A and the vertical dimension B are set to 1 μm to 50 μm, for example.

  In the first embodiment, the distances L1 and L2 between the printing elements 4 are, for example, values equal to or higher than the height H of the printing elements 4. Further, the printing area 10 has a larger area occupied by the ground surface 5 than the area occupied by the printing elements 4. Therefore, when the printing area 10 is viewed from the direction perpendicular to the surface 3, the decorative pattern formed by the set of printing elements 4 cannot be visually recognized by the naked eye, or can be visually recognized very thinly. In particular, in the first embodiment, the printing element 4 is made of transparent ink, so that it is more difficult to visually recognize with the naked eye.

  FIG. 3 is a schematic view when the surface 3 of the decorative body 1 is viewed obliquely from the direction of the white arrow 30 shown in FIG. That is, the surface 3 of the decorative body 1 is viewed obliquely in the horizontal direction of FIG. In FIG. 1, the printing element 4 is viewed from the angle indicated by the arrow 8. When the surface 3 of the decorative body 1 is viewed from an oblique direction as shown in FIG. 3, it overlaps the adjacent printing element 4 due to the height H of the printing element 4. Then, the ground surface 5 lined up in series with the printing element 4 toward the viewing direction is hidden by the height H of the printing element 4 on the near side and becomes invisible. As a result, the area occupied by the printing elements 4 in the printing region 10 increases visually, and the area occupied by the ground surface 5 decreases visually. At this time, since the plurality of overlapping printing elements 4 are easily visible, the decorative pattern formed by the set of printing elements 4 can be visually recognized.

  In addition, when the printing elements 4 are viewed from the angle indicated by the arrow 8 a in FIG. 1, that is, the angle closer to the vertical than the arrow 8, the ground surface 5 between the printing elements 4 is visible. Although the ground surface 5 can be seen, since the set of the printing elements 4 is seen obliquely from the vertical, the area occupied by the printing elements 4 in the printing area 10 is apparently increased. Therefore, although depending on the setting of the distance L between the printing elements 4, the decorative pattern becomes easier to see than when viewed from a direction perpendicular to the surface 3.

  3 is a view seen from the direction of the white arrow 30 in FIG. 2 from an oblique direction with respect to the normal of the surface 3, but when seen from the direction of the white arrow 31 pointing in the vertical direction of FIG. In FIG. 3, the printing elements 4 appear to overlap as shown in FIG. 3 when viewed from a predetermined angle oblique to the normal of the surface 3. In addition, even when viewed from the direction of the white arrow 32 in FIG. 2, the print elements 4 appear to overlap with each other when viewed from a predetermined angle oblique to the normal line of the surface 3. The distance between the four is an oblique direction distance L3, which is longer than that of the white arrow 30 and the white arrow 31.

  In FIG. 2, the printing elements 4 are arranged with an interval of a horizontal distance L1 and a vertical distance L2. The distance L1 in the horizontal direction and the distance L2 in the vertical direction are indicated by L in FIG. The horizontal distance L1 and the vertical distance L2 may be equal to each other or may be different values. However, in a direction parallel to the surface 3 of the decorative body 1, it is necessary to have a predetermined interval in at least one direction.

  The distance L between the printing elements 4 (at least one of the lateral distance L1 and the longitudinal distance L2) is closer to the normal line of the surface 3 of the decorative body 1 when viewed from an oblique direction with a larger angle. The printing elements 4 do not overlap. On the other hand, if the distance L is short, the adjacent printing elements 4 overlap each other only when viewed from an oblique direction with a small angle with respect to the normal line of the surface 3 of the decorative body 1. That is, by adjusting the dimension of the distance L, the angle in the oblique direction in which the decorative pattern formed by the set of printing elements 4 can be visually recognized can be adjusted. However, if the distance L is too small, the surface L of the decorative body 1 can be visually recognized from a substantially vertical direction. Therefore, it is desirable that the distance L has a value equal to or greater than the height H of the printing element 4. Since the height H of the printing element 4 can be 1 to 50 μm, specifically, the horizontal distance L1 or the vertical distance L2 is set to a range of 1 to 100 μm with a value equal to or higher than the height H. It is desirable. That is, it is desirable that the horizontal distance L1 or the vertical distance L2 between the printing elements 4 is set in a range not less than the height H of the printing elements 4 and not more than four times the height H.

  The print area 10 may include a plurality of areas in which a plurality of different distances L are set. Since there are regions where the distance L is different, a portion where the printing elements 4 appear to overlap with each other depending on the angle at which the surface 3 of the decorative body 1 is viewed, and a portion where the printed elements 4 do not appear can be formed. .

  FIG. 4 is a diagram when the longitudinal distance L2 of the printing element 4 is set to 0 with respect to FIG. FIG. 5 is a schematic view when the surface 3 of the decorative body 1 is viewed obliquely from the direction of the white arrow shown in FIG. In the first embodiment, the printing elements 4 may be arranged adjacent to each other in the vertical direction with the vertical distance L2 set to 0 or a value close to 0 as shown in FIG. 4, for example. However, at this time, the lateral distance L1 is separated by a predetermined interval. When the surface 3 of the decorative body 1 is viewed obliquely from the direction of the white arrow in FIG. 4, the ground surface 5 of the printing area 10 a is not visible as shown in FIG. 5, and the printing area 10 a is entirely covered with the printing elements 4. looks like. At this time, the decorative pattern formed by the set of printing elements 4 can be visually recognized in the printing region 10a. In FIG. 4, all the vertical distances L2 are set to 0. However, a portion having a large vertical distance L2 may be provided depending on the specification of the decorative pattern.

  In FIGS. 2 and 4, the printing element 4 is represented by a rectangle when viewed from the normal direction of the surface 3, but may be a circle, an ellipse, a triangle, or other shapes. Even if the shape of the printing element 4 takes various shapes, when viewed from an oblique direction with respect to the normal direction of the surface 3, depending on the value of the height H of the printing element 4 and the distance L between the printing elements 4 The printing elements 4 can be arranged so as to overlap.

  Moreover, the printing element 4 should just be what cannot be visually recognized independently, or is hard to visually recognize, for example, the printing element 4 cannot be visually recognized by making the surface roughness of the surface 3 of the base material 2 rough, or it is difficult to visually recognize. If it does, size is not limited. Furthermore, if the transparency of the ink constituting the printing element 4 is high, it is difficult to visually recognize it alone. Therefore, the size of the printing element 4 can be appropriately changed by changing the ink.
