Description

  The present invention relates to a decorative body having a special visual effect using a microlens.

  Conventionally, patterns using moire have been used as building materials and decoration materials. The most rudimentary moire pattern is obtained by overlapping two identical screens and rotating one screen. By applying this principle, the shape and angle of the pattern as the unit of the pattern. By changing variously, it is possible to create an infinite variety of patterns.

  On the other hand, there is known a decorative material that exhibits a special visual effect by using a microlens sheet in which microlenses that are fine convex lenses are regularly arranged on the surface of a transparent synthetic resin plate. The microlens sheet is an expensive sheet because it is a sheet manufactured by forming fine irregularities on the surface of a thermoplastic resin sheet using a precise mold. The decorative sheet described in Patent Document 1 is provided with a plurality of convex lens-shaped protrusions in a continuous pattern on the surface of a transparent sheet and a pattern having the same continuous pattern as the surface on the back surface of the sheet. It is a decorative sheet printed by being displaced with respect to a pattern.

  Attempts have also been made to form microlenses by printing rather than molding. The dot-drawn pattern decorative body described in Patent Document 2 is a regular arrangement of a large number of independent convex condensing elements having transparency on a surface of a transparent substrate by a printing ink having transparency at a constant fine pitch. A large number of colored pixels are printed on the back surface of the transparent substrate in the same shape as the convex condensing elements on the front surface or in the same arrangement state or in different shapes and the same arrangement state. The positional relationship is shifted with respect to the convex condensing element on the surface so that the size changes greatly, and the colored pixels appear as an enlarged image with a stereoscopic effect when viewed from the surface, and the viewpoint is moved. And an enlarged image of a point drawing pattern characterized in that the enlarged image exhibits a sense of fluctuation.

  This decorative object is a three-dimensional dot drawing pattern that uses the phenomenon that the amplitude increases or decreases when the crossing angle is shifted by overlapping regular patterns like halftone dots, and the dots appear to fluctuate. It is a decorative body that has appeared.

  The three-dimensional pattern decorative body described in Patent Document 3 is provided with a plurality of layers or a single layer in a predetermined pattern continuously with a dot-like pattern colored in a desired color on the surface of a transparent or opaque decorative body, A transparent dot-shaped convex lens having a substantially hemispherical cross section is continuously attached to the surface of the decorative body and each pattern in the same pattern as the above pattern, and a moire pattern appears on each pattern and each convex lens pattern. The pattern and the convex lens are arranged so as to gradually become dense toward the dense area set on the surface of the decorative body, and are arranged in a rough area set in a portion far from the dense area. It is a three-dimensional pattern decorative body arranged in a gradation that gradually becomes rough toward. This decorative body can three-dimensionally display a gradation moire pattern having a dense area and a rough area.

  The decorative sheet described in Patent Document 1 must be expensive because a lens sheet using a mold is used. Moreover, as long as a lens sheet using a mold is used, it is not impossible to realize a design in which the effects of the lens are partially arranged, but it is more difficult in terms of cost.

  Since the decorative body of the point drawing pattern described in Patent Document 2 and the three-dimensional pattern decorative body described in Patent Document 3 both form lenses by printing means, it is not possible to use expensive molds. However, since a screen printing method that relatively easily deposits ink is used as a means for forming lenses, there is a limit to accurately forming and arranging fine lenses over a large area. The screen printing method is slow in printing speed and is not suitable for mass production.

  In addition, since any of the above decorative bodies realizes the generation of a moire pattern by a method of changing the angle of one pattern, the generated moire pattern itself is accompanied by some angle and gives a controlled and neat impression. It cannot be said to be a thing.

  The problem to be solved by the present invention is to provide a decorative body in which fine lenses are formed and arranged with high precision and a pattern by a visual effect whose directionality is accurately controlled appears.

As means for solving the above-mentioned problems, the invention described in claim 1 includes a visual expression pattern provided in a dot pattern with a pitch A on a substrate, and a varnish having liquid repellency on the visual expression pattern surface. A liquid repellent pattern provided in a letter B shape at a pitch B, and a microlens formed on the letter character portion by applying a transparent varnish on the liquid repellent pattern, the pitch A and the pitch B being Since the visual expression pattern and the microlens are arranged at the same angle with respect to the horizontal direction, the pattern in which the dot pattern of the visual expression pattern is enlarged appears at an equal pitch and is three-dimensional. It is a decorative body to be visually observed, wherein a reflective layer and a transparent layer are provided in this order between the base material and the visual expression pattern.

The invention described in claim 2 is the decorative body according to claim 1, wherein the transparent layer is colored .

  The invention according to claim 3 is the decorative body according to claim 1 or 2, wherein a pattern in which the dot pattern of the visual expression pattern is enlarged is partially displayed.

  In the decorative body according to the present invention, a microlens is formed by a liquid-repellent pattern provided in a letter shape using a liquid-repellent varnish and a transparent varnish applied on the liquid-repellent pattern. A lens can be efficiently formed by a printing method. For this reason, the decorative body according to the present invention is a sophisticated decorative body with a fine visual effect.

  In addition, the decorative body according to the present invention is a pattern in which the dot pattern of the visual expression pattern is enlarged by changing the pitch of the visual expression pattern and the microlens provided in a dot pattern on the substrate (hereinafter abbreviated as an enlarged pattern). Therefore, the enlarged pattern maintains the same directivity in common with the visual expression pattern and the microlens pattern, and gives a tightly controlled impression. In addition, since the generated enlarged pattern appears to move as the viewpoint moves, a three-dimensional feeling is expressed.

  Moreover, since the decorative body which concerns on this invention provided the reflective layer between the base material and the visual expression pattern, an enlarged pattern is expressed strongly.

  When the transparent layer is provided between the reflective layer and the visual expression pattern layer, the stereoscopic effect of the enlarged pattern is further enhanced. Moreover, it becomes possible to express arbitrary metal colors by coloring a transparent layer.

  Furthermore, in the decorative body in which the enlarged pattern is partially shown, it is possible to make the decorative body with a complicated and sophisticated expression.

FIG. 2 is a cross-sectional explanatory view showing another embodiment of the decorative body according to the present invention. FIG. 3 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the decorative body according to the present invention. FIG. 4 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the decorative body according to the present invention, in which the enlargement magnification is lower than that in FIG. FIG. 5 is an enlarged plan view showing another embodiment of the decorative body according to the present invention.

Hereinafter, the decorative body according to the present invention will be described in detail with reference to the drawings.
FIG. 1 is a cross-sectional explanatory view showing an embodiment of a decorative body according to the present invention. The decorative body according to the present invention includes a visual expression pattern 3 provided on the base material 1, a liquid repellent pattern 4 provided on the visual expression pattern 3 using a varnish having liquid repellency, and a liquid repellent pattern 4. It has a microlens 5 formed on the extracted character portion by applying a transparent varnish thereon, and a reflective layer 2 is provided between the substrate 1 and the visual expression pattern 3.

  As the substrate 1, a substrate made of any material such as paper, a synthetic resin film, and a synthetic resin plate can be used. In order to make good use of paper, a paper or a synthetic resin film that can use the offset printing method or the gravure rotary printing method is desirable. Printing by a screen printing method may be applied using a plate material such as a synthetic resin plate as a base material.

  As the reflective layer 2, a metal foil, a metal vapor deposition layer, an ink layer containing a bright pigment such as a metal powder pigment or a pearl pigment, or the like is used. You may use the vapor deposition paper and vapor deposition film which vapor-deposited aluminum on paper and a film as a base material with a reflecting layer. Due to the presence of the reflective layer 2, the incident external light is reflected by the reflective layer and emitted, so that the amount of reflected light increases and the enlarged pattern appears strongly.

  As the visual expression pattern 3, an arbitrary figure such as a circle, a rectangle, a triangle, a heart shape, or a character can be refined and used. The visual expression pattern 3 is printed using a transparent colored ink or an opaque colored ink which is arranged in a dot pattern and is usually used according to the printing method.

The liquid repellent pattern 4 is formed in a letter shape using ink having liquid repellency. As the liquid-repellent ink, inks obtained by adding a small amount of silicone oil or silicone resin to normally used inks or varnishes, or inks using silicone resins or fluorine-based resins as binders can be used. Usually, the liquid-repellent pattern is generally colorless and transparent, but may be appropriately colored in order to obtain a design effect. The shape of the liquid repellent pattern 4 is arbitrary, such as a polka dot negative arranged in a regular triangle shape as shown in FIG. 3, a polka dot negative arranged in a square shape, a grid pattern, or a honeycomb shape.

  When a transparent varnish is applied to the surface of the liquid repellent pattern 4 and repelled along the liquid repellent pattern, the transparent varnish gathers in the extracted character portion of the liquid repellent pattern and rises in a convex shape to form the microlens 5. The transparent varnish is preferably a resin composition with good transparency that does not contain a filler such as a matting agent and has a high solid content. An ultraviolet curable transparent gloss varnish having a solid content of 100% can be preferably used.

  FIG. 2 is a cross-sectional explanatory view showing another embodiment of the decorative body according to the present invention. In this embodiment, a transparent layer 6 is provided between the reflective layer 2 and the visual expression pattern layer 3. The transparent layer 6 functions to lengthen the optical paths of the incident light and the reflected light and enhance the stereoscopic effect of the enlarged pattern. As the transparent layer 6, a transparent resin coating film or a transparent film can be used.

  When the transparent layer 6 is colored using a transparent pigment or dye, various metallic luster can be expressed. For example, when the reflective layer 2 is made of an aluminum foil and the transparent layer 6 is made tan, gold can be expressed. Similarly, when the transparent layer 6 is gray, a stainless steel texture can be provided.

  FIG. 3 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the decorative body according to the present invention. In this embodiment, the visual expression pattern 3 is a circular dot and is arranged in a regular triangle shape with a constant visual expression pattern pitch 7. A liquid repellent pattern 4 formed from above using liquid repellent ink is provided. The liquid repellent pattern 4 is a negative pattern of circular dots arranged in a regular triangle shape with a constant microlens pitch 8, that is, a letter shape, and the transparent varnish applied on the liquid repellent pattern 4 is repelled. The microlenses 5 are formed by gathering at the circular dot portions that are the extracted characters. A suitable size of the microlens 5 is about 0.05 mm to 0.5 mm.

  When the visual expression pattern pitch 7 and the microlens pitch 8 are set to different values, the positions of the dots of the visual expression pattern 3 and the microlens 5 gradually shift, and try to coincide again at a position shifted by one pitch. In the part where both coincide, the central part of the visual expression pattern 3 is enlarged by the microlens 5, and in the part where they do not coincide, the intermediate part of the visual expression pattern is enlarged by the microlens 5. In this way, the portion of the visual expression pattern to be enlarged gradually shifts and moves back to the original position at a position shifted by one pitch. As a result of repeated matching and non-matching of the pitch, it is recognized as if the visual expression pattern was enlarged when viewed with the naked eye. The values of the visual expression pattern pitch 7 and the microlens pitch 8 are preferably about 0.05 mm to 1.0 mm.

  FIG. 4 is an enlarged plan view illustrating a mechanism in which an enlarged pattern is generated in the decorative body according to the present invention, in which the enlargement magnification is lower than that in FIG. As can be seen from the figure, a region 9 in which the central portion of the visual expression pattern is enlarged and a region 10 in which the middle portion of the visual expression pattern is enlarged appear at regular intervals. This appears as an enlarged pattern and is recognized by the naked eye.

FIG. 5 is an enlarged plan view showing another embodiment of the decorative body according to the present invention. In this embodiment, the visual expression pattern 3 is a square, and the square is arranged at the same pitch 7 as in FIG. The specifications of the microlens 5 are the same as in FIG. 3, and the microlens pitch 8 is also the same. In this way, as the enlarged pattern, a square-shaped enlarged pattern that is the shape of the original visual expression pattern 3 appears. In this way, as the visual expression pattern, a picture having an arbitrary shape can be used, and the enlarged pattern that appears is a figure obtained by enlarging the original visual expression pattern.

  In the decorative body according to the present invention, only the visual expression pattern pitch 7 and the microlens pitch 8 are changed, and the angle is not changed. Therefore, the angle of the enlarged pattern that appears is equal to the angle of the original visual expression pattern 3. In the case of FIG. 4, the horizontal direction and the direction inclined by 60 ° to the left and right. In general, the moire pattern that appears when the angle of the pattern is changed appears at an angle different from the angle of the original pattern, so it gives the impression that it appears by chance, and gives a controlled impression. Although not given, the decorative body according to the present invention is characterized in that the enlarged pattern appears in a direction equal to the angle of the pattern, so that the enlarged pattern is precisely controlled.

When the visual expression pattern pitch 7 is smaller than the microlens pitch 8, the enlarged pattern becomes an upright enlarged image in the same direction as the original visual expression pattern 3, but the visual expression pattern pitch 7 is smaller than the microlens pitch 8. Is larger than the original visual expression pattern 3, an inverted inverted image is formed.
Hereinafter, specific description will be given based on examples.

  A coated cardboard having a basis weight of 310 g was used as a base material, and an aluminum foil having a thickness of 7 μm was bonded to the surface to form a reflective layer. A visual expression pattern 3 of polka dots as shown in FIG. 3 was printed on the surface of the reflective layer with black ink using an offset printer. The dot diameter was 0.2 mm and the pitch was 0.31 mm. Next, a liquid repellent pattern 4 was printed thereon using a repelling ink in which silicone oil was added to the ink medium. The diameter of the polka dots to be the microlens was 0.3 mm, and the pitch was 0.33 mm. From this, a transparent gloss varnish was applied to the entire surface to form a microlens. The resulting decorative body shows a polka dot pattern in which the dot pattern of an approximately 5.5 mm pitch visual expression pattern that is regularly arranged appears, and the pattern moves as the viewpoint moves. It was. Furthermore, since the surface has fine embossing based on the unevenness of the microlens, the decorative body has a good touch and a high-class feeling.

  Using a base material provided with a reflective layer similar to that used in Example 1, a yellow-brown transparent varnish was applied as a transparent layer on the surface of the reflective layer, and then a decorative body was produced in the same manner as in Example 1. did. The resulting ornament was a golden luxury ornament.

  A coated cardboard having a basis weight of 310 g was used as a base material, and an ink layer containing a silver metal powder pigment was provided on the surface by a gravure coating method to form a reflective layer. A transparent layer by a medium coat was provided thereon, and a square dot visual expression pattern as shown in FIG. 5 was printed using black ink by an offset printer. The length of one side of the dot was 0.2 mm, and the pitch was 0.31 mm. Next, a liquid repellent pattern 4 was printed thereon using a repelling ink in which silicone oil was added to the ink medium in the same manner as in Example 1. The diameter of the polka dots to be the microlens was 0.3 mm, and the pitch was 0.33 mm. From this, a transparent gloss varnish was applied to the entire surface to form a microlens. The resulting decorative body shows a square pattern in which the dot pattern of the visual expression pattern of approximately 5.5 mm pitch arranged regularly is displayed, and the pattern moves as the viewpoint moves, so that a three-dimensional feeling can be expressed. It was. Furthermore, since the surface has fine embossing based on the unevenness of the microlens, the decorative body has a good touch and a high-class feeling.

In the decorative body having the same configuration as in Example 1, the visual expression pattern was printed so as to be in the range of 7 cm × 7 cm, and the liquid repellent pattern using the repellent ink added with silicone oil was added to the ink medium. A microlens was formed in the same manner as in Example 1 by printing in a 5 cm × 5 cm range smaller than the printing range. In the part where the microlens was formed, an enlarged pattern with movement appeared due to the movement of the viewpoint. By contrast with the part where the microlens did not exist, it became a decorative body with a more three-dimensional feeling and depth.
