DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A basic embodiment of the present invention is directed to a colored or uncolored transparent substrate B as shown in FIG.
A large number of colored or uncolored convex concentrators (hereinafter abbreviated as “concentrators”) A having a role of convex lenses are regularly arranged on the surface of the substrate (hereinafter abbreviated as “substrate”) at a constant pitch. The substrate B is printed in an array, and a number of colored pixels (hereinafter abbreviated as “pixels”) C arranged in the same state as the concentrator A on the front surface are formed on the back surface of the substrate B at an intersection angle with respect to the concentrator A on the front surface. By printing with a slight shift, the pixel C appears as an enlarged image having a three-dimensional effect when viewed from the surface, and when the viewpoint is moved, a decorative body having a dot-drawing pattern in which the enlarged image exhibits a fluctuating feeling is obtained.

The point-drawing pattern appearing according to the present invention is:
In the case where the pixel C is a circular dot of one color, the size and the shading change due to the shift of the intersection angle between the pixel C in the fixed array and the concentrator A in the fixed array, and the pixel is enlarged with a regular three-dimensional effect. The enlarged polka dot pattern appears on the upper surface of the substrate B, and when the viewpoint is moved, the enlarged polka dot pattern moves and becomes a pattern with a sense of fluctuation (see FIG. 5).

Further, when two or more kinds of pixels C of a fixed array are used on the back surface of the substrate B and the pixels C are overlapped with the crossing angles of the light collecting elements A of a fixed array, the color of the pixels C is changed. Are embedded symmetrically around the intersections, resulting in various embedded point drawings such as regularly arranged striped patterns, and when these point patterns change the field of view, a sense of fluctuation occurs.

Further, as another embodiment of the present invention, similarly to FIG. 1, a large number of colored or uncolored condensing light having a transparency functioning as a convex lens is formed on the surface of a colored or uncolored substrate B. The elements A are printed in a regular arrangement at a constant pitch, and the rear surface of the substrate B is replaced with the pixels C of FIG. A large number of colored or uncolored light-collecting elements A '(not shown) having a role of an array of convex lenses
Is printed with the crossing angle slightly shifted with respect to the concentrator A on the surface, so that the convex concentrator A and the convex concentrator A ′ are synthesized from both the front and back surfaces. An enlarged image having a three-dimensional effect appears, and when the viewpoint is moved, a decorative body having a dot-drawing pattern in which the enlarged image exhibits a fluctuating feeling is obtained.

It is considered that the fluctuation phenomenon of the enlarged point drawing pattern is caused by an illusion due to an afterimage effect seen through the light condensing element A or A 'having a lens effect. or,
The three-dimensional effect of the dot drawing pattern is such that an image having a different focus is formed between the pixel C and the viewpoint (eye) due to the lens effect of the condensing element A printed in a regular array on the substrate B at a constant pitch. It is considered that the outline is enlarged and becomes a blurry special pattern.

The material of the substrate B in the present invention is not limited as long as it transmits visible light, and is not limited to inorganic or organic materials as long as it is colored, and any material such as a glass plate, a resin plate, and a film can be used. A polyester film, an acrylic film, a polycarbonate plate, or the like is convenient in terms of availability and easy acquisition and processing, but is not particularly limited.

What is important in the substrate B of the present invention is the thickness. The thickness of the substrate B cannot be specified because it greatly affects the form of the stippled image depending on the diameter of the pixel C, the diameter and the height of the light-collecting element A, and the like. desirable.

The thicker the substrate B, the more the fluctuation becomes remarkable. However, if the thickness is too large, the image becomes blurred or the color becomes faint, and the handling becomes inconvenient. Difficult, flat print feeling and less fluctuation.

Therefore, the thickness of the substrate B should be between 10 μm and
10 mm can be applied, preferably 50 μm to 5 μm.
mm is practical.

As the pixel C in the present invention, a circle, a square, a star, a triangle, an ellipse, a linear shape, or any other shape as shown in FIG. 2 can be used. 1 μm to 1 mm, preferably 1 μm to 100 μm
The thickness of the substrate B is 点 or less, preferably １ ／ or less. If the pixel C is too large, the dot drawing image is disturbed.

Although the height of the pixel C is not particularly limited,
From the relation of printability, about 1/10 to 1/2 of the diameter of the pixel C is a height that can be normally used.

A large number of light condensing elements A and pixels C are regularly arranged at a constant pitch on the plane of the substrate B. When the intersection angle (θ) between the light condensing element A and the pixels C becomes 45 ° or more, Since the same pattern is repeated, it is limited to the range of 0 <θ <45 °.

When two or more types of pixels C are printed, adjacent pixels C may be in contact with each other or may be separated from each other.
The point drawing image is easily disturbed, so it should be within that range.

When the two or more kinds of pixels C are combined, the same orientation or different orientations may be used. However, if the orientations are different, depending on the intersection angle with the light condensing element A, the pixels C may have different orientations. The shape of the shape is lost and the pattern becomes complicated.

In the present invention, when two or more types of pixels C are used in combination, a method of overprinting on the back surface of the same substrate B may be used, but as shown in FIG. May be superimposed on the back surface of the substrate B.

The shape and arrangement of the light condensing element A are arbitrary, like pixels, and are determined by a desired dot drawing pattern. However, it is generally easy to print the same shape and arrangement as the pixels C, Even in this case, the size and outline state of the pixel C which appears as a dot drawing pattern changes depending on the amount by which the intersection angle between the pixel C and the light-collecting element A is shifted.

Therefore, in the present invention, when printing a plurality of pixels C on the back surface of the substrate B, the shape of the pixels C
For example, pixels C of the same shape and the same array are printed at the same pitch and slightly shifted from each other on the various character and design portions and other ground portions, and a plurality of the back surfaces are printed on the front surface of the substrate B. By printing a light-collecting element A having the same shape and the same arrangement as that of any of the pixels C and slightly crossing any of the plurality of pixels C, the character or pattern portion and the other As shown in FIG. 5, an enlarged dot drawing pattern having a different size from the ground portion is obtained, and each dot drawing pattern exhibits a different state in terms of three-dimensional effect and fluctuation. can get.

In the above case, the outline F of the character or the pattern (the star in the center in FIG. 5) may be bordered by solid printing to make the character or the pattern stand out. If the range is provided only on the upper surface of the character or pattern portion, a dot drawing pattern exhibiting a three-dimensional effect and a fluctuation feeling enlarged only in the character or pattern portion can be obtained.

The material of the light-collecting element A may be transparent or transparent as in the case of the substrate B, and may be colorless or colored. The condition is that the ink has good printing characteristics. Therefore, in the present invention, there is no particular limitation as long as the ink has good adhesiveness, transparency and thick buildability.

The light condensing elements A may be arranged in a manner not to overlap two or more kinds of shapes. In this case, however, the combination with the pixels C results in complicated and various dot drawing patterns.

Further, when a colored transparent ink is used as the light condensing element A or when a colored transparent substrate is used as the substrate B, a dot drawing pattern of a color synthesized with the color of the pixel C is obtained.

As a means for forming the light condensing element A and the pixels C on the substrate B, well-known screen printing and transfer printing can be applied.

The point drawing pattern appearing by the present invention will be elucidated by optical theory in the future, and the refractive index of the light-collecting element and the substrate, the shape and height of the light-collecting element, the thickness of the substrate, the shape of the pixel,
It can be calculated by the arrangement of pixels and condensing elements and the angle of intersection, but at this stage it is too complicated and must rely on empirical rules.

However, the following method is convenient as a method of determining a point drawing pattern. First of all, prepare the two thin substrates with the element and the pixel printed separately, stack them so that the back side of the substrate side where the element is printed on the pixel side is in contact, and shift one of them to align Since the pattern changes variously when the axes are crossed, the crossing angle at which the desired point-drawing pattern is obtained is determined. By doing so, the same point drawing pattern as above is reproduced.

In this case, when using two kinds of pixels, first, two kinds of pixels are separately printed on two thin substrates, and they are appropriately shifted and overlapped. The desired back-and-forth pattern is determined by overlapping the back surfaces of the substrates on which photons are printed and shifting each substrate to change the intersection angle between the pixel and the light-collecting element. As a product, two types of pixels are provided on the back surface of the same substrate. Are shifted, and the condensing element is printed on the surface of the substrate to reproduce the same dot pattern as described above.

Further, the combination of the light condensing element A, the substrate B, and the pixel C can be any combination.
For example, as shown in FIG. 4, a pixel C is printed on the surface of the substrate D, the transparent ink E is printed on the entire surface, and the condensing element A is printed on the upper surface. Is obtained.

In the present invention, since the condensing element A having a lens effect can be provided by printing, the diameter, height, Since the color, shape, arrangement state, and the like can be arbitrarily and easily changed, the degree of freedom of design as a decorative body increases.

It should be noted that a moving dot drawing pattern can be obtained by adopting a mechanism for rotating one or both of the pixel-side substrate and the light-collecting element-side substrate by using the above-described principle. You can also.

The results of experiments on the three-dimensional effect of the dot drawing pattern, the sharpness of the image, the sensation of fluctuation, the size of the pattern, and the like under various combinations of the components in the basic form of the present invention will be described below.

Table 1 shows that a light condensing element A, 410 made by Jujo Kasei Co., Ltd., was formed on the surface of a polycarbonate substrate B having a thickness of 1 mm.
Using transparent ink of the 0 series, the dots are arc-shaped with a diameter of 250 μm for 30 lines, a diameter of 120 μm for 60 lines, a diameter of 60 μm for 120 lines, and a height of 30 μm each. Pixels have the same diameter and height, respectively. FIG. 6 is a graph showing the size of the dot drawing pattern due to the uniaxial intersection of the light-collecting element A and the pixel C when a 3 μm circular dot is printed.

[0042]

[Table 1]

From this graph, it can be seen that when the intersection angle between the light-collecting element A and the pixel C is the same, the size of the pattern is inversely proportional to the number of lines (the number of dots). It can be seen that the size of the pattern is inversely proportional to the intersection angle when the light-collecting elements or the ratio of the pixels are the same.

Table 2 shows the appearance of the dot drawing pattern depending on the thickness of the polycarbonate substrate B. A circular dot formed by condensing element A and pixel C under the condition of 60 lines and 30% is separated by about 30 cm. 5 shows a state viewed from the vertical direction.

[0045]

[Table 2]

From this table, the three-dimensional effect of the dot drawing pattern as an enlarged image can be obtained even if the substrate B is thicker than 3 mm.
Further, even if it is thinner than 0.188 mm, it becomes worse, and the feeling of fluctuation is larger for thinner ones than for thinner ones, but it becomes difficult to confirm the image as the viewpoint shifts.

In the above experiment, it was confirmed that the closer the form of the light-collecting element A to a hemispherical shape, the greater the three-dimensional effect and the fluctuation effect. Therefore, the height of the light-collecting element A and the thickness of the substrate B affect the three-dimensional effect and the fluctuation effect of the dot drawing pattern.

Table 3 shows the sharpness of the dot drawing pattern according to the relationship between the number of lines of the light condensing element A and the number of pixels C and the percentage on the polycarbonate substrate B having a thickness of 1 mm.

[0049]

[Table 3]

From this table, when the number of lines is 60, it is 20 to 50%, when the number of lines is 90, it is 30 to 50%, and when the number of lines is 120, it is 40 to 50%.
%, The number of lines is 133 and 50%, that is,
It can be seen that those indicated by と and ○ are excellent in stereoscopic effect and image clarity.

However, the evaluation of good or bad in Tables 2 and 3 is based on the personal feelings of a plurality of researchers. Even in the case of the image indicated by 表 in the table, the outline of the image is slightly blurred. It has utility value depending on the purpose of use.

The above results show that, as the light-collecting element A, circular dots of 30 dots in diameter, 250 μm in diameter, 60 lines in diameter, 120 μm, 120 lines in diameter, 60 μm in height and 30 μm in height were printed in a circular arc using transparent ink. An experiment was conducted on a case where a circular dot having the same diameter as described above and a height of 3 μm was printed as the pixel C. The pixel was formed as a square shown in FIG. The same tendency was shown for the star shape shown in ()).

[0053]

According to the present invention, according to the shape and arrangement of the colored pixels printed on the rear surface of the transparent substrate, various convex condensing elements serving as lenses are printed on the surface of the transparent substrate. it is possible to provide at freely shifting state by, easy decoration of points drawn pattern that Teisu any three-dimensional effect or vibration sensation, and can be formed inexpensively.

Therefore, the decorative body according to the present invention can be viewed with interest, and can be used for various display boards, printed matter, labels, toys, etc., and has a wide range of uses, and the industrial applicability of the present invention is very large. It can be said.
