Description

  The present invention relates to a microlens decorative body that changes depending on a gas concentration that exhibits a design or color effect as a decorative sheet for packaging materials such as commercial printed matter and packages.

  As a conventional technique, pattern printing of hajikinis is performed on the printing substrate by offset or gravure printing, etc., and then gloss varnish is coated to make gloss varnish into hajikinis by utilizing the incompatibility between gloss varnish and haji kinis. On the other hand, there is a technique for constructing a gloss varnish pattern that is repelled and bounced and raised in three dimensions. Further, there is a method of making a thick film gloss varnish pattern using screen printing or the like.

  These pattern forming techniques are used for embossed decoration on the surface of a packaging material constituted by an inexpensive raised pattern by being applied to the surface of the packaging material of a package such as a paper box. By applying this technique, it is possible to make the gloss varnish into a convex lens shape. By combining a microlens made using this method with a visual expression pattern, it is possible to create a decorative body with a visual effect that looks like the pattern moves as the line of sight moves. As the decorative body, for example, there is a decorative body disclosed in Patent Document 1 or the like.

  However, the visual effects of the decorative body's microlenses and visual expression patterns have been able to make the pattern appear to change as the line of sight moves, but there are no more color or decorative changes. Further, there was a limit to the way of further expression and use as a decorative body. Moreover, in the conventional method like the cited document 1, the decoration body by the combination of the microlens and the visual expression pattern does not change except for the variable visual effect that is expressed by the movement of the line of sight in the visual effect.

  An embodiment of a microlens decorative body of the present invention will be described in detail below with reference to the drawings. The decorative body of the present invention is a paper, resin film, as shown in a side sectional view of FIG. , A predetermined pixel pitch p1 (for example, 0.05 to 1.0 mm) on one surface of any one of the metal foil, aluminum-deposited paper, metal-deposited paper, metal-deposited film, and bonded paper and resin plate In a striped pattern, or in a negative pattern, arranged at regular intervals with respect to a checkered pattern arranged on three straight lines intersecting in the θ = 60 ° direction (see FIG. 2B) A visual expression pattern layer 2 composed of a group of pixels is provided. As a material for forming the visual expression pattern layer 2, an oxygen concentration sensing ink that changes a color tone or transparency by sensing a change in oxygen concentration or a temperature sensing ink that senses a color tone or transparency by sensing temperature or an ultraviolet ray is sensed. Use UV sensitive ink that changes color or transparency. Then, printing is performed by offset printing, gravure printing, screen printing, letterpress printing, ink jet printing, or the like.

  As an oxygen concentration sensing ink whose color and transparency change depending on the oxygen concentration, there is an oxygen indicator ink (manufactured by Toppan Printing Co., Ltd.) specification, and the composition is methylene blue 3 parts by weight, L ascorbic acid 7.5 parts by weight, binder 10 parts by weight of resin, 7.5 parts by weight of glycerin, and 0.6 parts by weight of synthetic silica. Examples of temperature sensing ink include temperature indicator ink (ST color, temperature type 15 (manufactured by Kuboti Ink Co., Ltd.)) and temperature indicating ink (Metamo ink, manufactured by Pilot Ink Co., Ltd.). (Recording Materials Research Laboratory) and Sunny Color Blue (Recording Materials Research Laboratory).

  The pixels constituting the pixel group are, for example, parallel lines (straight lines, wavy lines, dotted lines, etc.) of the same shape, and are arranged in a one-dimensional direction at regular intervals to form a pixel group. Or a dot-like pixel with three points (triangle, quadrangle, hexagon, circle, ellipse, etc.) as a unit, and a group of pixels arranged regularly and repeatedly in a two-dimensional direction It is.

  On one surface of the base material layer 1, a lens pitch p0 (for example, 0.03 to 0.03) different from the pixel pitch p1 corresponding to the shape of each pixel constituting the visual expression pattern layer 2 (pixel group). 1.5 mm) in a striped pattern, or in a negative pattern with respect to a checkered pattern arranged on three straight lines intersecting the θ = 60 ° direction (see FIG. 2B). The hajikinis layers 3 arranged in the above are formed with substantially the same film thickness and with substantially the same width, for example, thicker than the film thickness of the visual expression pattern layer 2. The varnish material of the hajikinis layer 3 may be transparent, translucent, or opaque. However, incompatible varnishes are used for the transparent gloss varnish which is a micro convex lens material described later. A convex lens material having hazy properties is used. The diameter (diameter) of each pixel 2 constituting the visual expression pattern layer is not particularly limited, but is preferably smaller than the lens pitch p0, for example, about 0.02 to 1.0 mm.

  The pattern of the Hajikinis layer 3 is a substantially negative pattern with respect to a group of pixels in which pixels having the same shape, for example, parallel lines (straight lines, wavy lines, dotted lines, etc.) are repeatedly arranged at equal intervals in a one-dimensional direction, Or a negative pattern for a pixel group in which dot-like pixels with three points (triangle, square, hexagon, circle, ellipse, etc.) as a unit are regularly arranged in a two-dimensional direction. It is.

  Between each hajikinis layer 3 formed at equal intervals on one side of the base material layer 1 (region where the hajikinis layer 3 is not formed), transparent gloss varnish having hajikin properties (incompatible) with respect to hajikinis, The transparent gloss varnish that is applied and filled on the base material 1 from the top of the hajikinis layer 3 to a thickness slightly larger than the thickness (height) of the hajikinis layer 3 is retained by the hajikinis layer 3. The micro-convex lens array 4 is formed of an array of fine micro-convex lenses with a lens pitch p0 by being bounced and raised to a convex lens shape (arc shape) and then dried and solidified. The width of one stripe of the micro convex lenses 4 arranged in a one-dimensional direction in a stripe shape and the diameter (diameter) of the micro convex lenses 4 arranged in a two-dimensional direction in a dome (cubic) shape are, for example, 0.05. Appropriate values are approximately 1.0 mm and 0.05 mm to 1.0 mm.

  Since the transparent gloss varnish formed thicker than the film thickness (height) of the hajikinis layer 3 repels and repels the hajikinis layers 3, 3, 3,... The transparent gloss varnish that has been moved (flowed) and retained between each hajikinis layer 3 from above each hajikinis layer 3, and the upper portion of the transparent gloss varnish retained between each hajikinis layer 3 has a convex lens shape due to its surface tension. It is raised and formed in an arc shape.

  The pixels of the visual expression pattern layer 2 and the convex lenses of the micro-convex lens array 4 correspond to each other in the planar shape, and in the case where each pixel is a pixel in a parallel line shape (straight line, wavy line, dotted line, etc.) A parallel (stripe) micro convex lens array 4 in which cylindrical (lenticular) micro convex lenses are repeatedly arranged in a one-dimensional direction (horizontal direction) corresponding to the linear pixels is used.

  When each pixel is a dot-like (triangle, quadrangle, circle, ellipse, etc.) pixel, a cross-view dome-like (cubic) micro-convex lens is formed in a planar viewpoint (triangle, quadrangle) corresponding to the dot-like pixel. A micro-convex lens array 4 such as a honeycomb-shaped lens or a spider-shaped lens repeatedly arranged in a two-dimensional direction (vertical and horizontal directions) in a checkered pattern in a hexagonal shape, a circular shape, an elliptical shape, or the like.

  For each pixel 2 of the visual expression pattern layer observed through each convex lens 4 of the micro convex lens array of the micro lens decoration body of the present invention, FIG. 1 (a), FIG. 2 (b), FIG. ).

  The pixel pitch p1 of each pixel 2 of the visual representation pattern layer of the microlens decorative body of the present invention and the lens pitch p0 of each convex lens 4 of the micro convex lens array (two-dimensional array or one-dimensional array) are their pitch values. P0 <p1 or p0> p1. Therefore, when each convex lens 4 of the micro convex lens array (stripe-shaped convex lens array) is stacked on each pixel 2 of the visual expression pattern layer, As shown in 1 (a), (b) and FIGS. 2 (a) and 2 (b), the pixel pitch and the convex lens pitch are stacked with the pitches slightly shifted from each other.

  The pixel pitch p1 and the micro convex lens pitch p0 of the microlens decorative body of the present invention are set to different pitches, and are laminated with the pitches slightly shifted from each other. Therefore, when each pixel 2 of the visual expression pattern layer is viewed through the microlens array, optical interference moire (moire fringes) is generated in the visual expression pattern layer due to the pitch shift of the two different pitches. At this time, moire occurs as an expression pattern (1 <N ≦ (1.5 to 10)) in which the pixel 2 is enlarged by N or N repetitions according to the difference between p1 and p0.

Figure 1 (a), the as the pixel pitch p ₁ of each pixel 2 constituting the pixel group of visual representations pattern layer, the convex lenses constituting the micro lens group of the microlens array differ from pixel pitch p ₁ 4 The lens pitch of the lens array is p ₀ , the number of moiré patterns generated in the span S region (the number of repetitions of the pixels and ground colors in the lens 1 pitch) is N, and the lens array pitch of the lens pitch value p _{0 in} the span S region is The number of moire generated when the microlens array is laminated on the visual expression pattern layer (the number of moire repetitions) where P0 is the number (number of repetitions of pitch) and P1 is the number of pitches of the visual expression pattern layer with the pixel pitch value p1 N is the absolute value of the difference between the lens array pitch number P0 and the visual expression pattern layer pitch number P1,
N = | P1−P0 |
It becomes.

  For example, as shown in FIGS. 1A and 1B and FIGS. 2A and 2B, at the position a of the microlens array, the hajikinis layer 3 between the convex lenses 4 and 4 adjacent to the pixel 2 is formed. The pixel 2 in the visual representation pattern layer that exists directly below cannot obtain a visual magnification effect by the lens, and at the position b, the pixel 2 in the visual representation layer exists in the center of the convex lens 4 and In the position c, the pixel 2 exists at a position slightly shifted from the position immediately below the Hajikinis layer 3 between the adjacent convex lenses 4 and 4, and the visual expansion effect cannot be obtained. In d, similarly to the position a, the pixel 2 exists again immediately below the Hajikinis layer 3 between the adjacent convex lenses 4 and 4, and a visual expansion effect cannot be obtained.

  As shown in FIGS. 1A, 1B, and 2A, a visual enlargement effect by moire is obtained around the position b, and the direction from the position b to the position a, and from the position b to the position c. The visual enlargement effect becomes lighter as it goes in the direction of, and the number N of moire around the position b is about 1.

In this case, the position a to the position d is the span S in which the generation cycle of the optical interference moire is one cycle, but the pitch number (the number of repetitions of the pitch) P0 of the lens (lens pitch value p0) in the span S region is ,
P0 = S / p0
The number of pitches (number of pitch repetitions) P1 of the pixels (pixel pitch value p1) in the span S region is
P1 = S / p1
The number of moiré occurrences (the number of moiré repetitions) N is
N = | P1−P0 |
It becomes.

  In the present invention, the number N of optical interference moiré (moire fringes) due to pitch deviations of different pitches is determined by the number of pixel pitches P1 of the visual representation pattern layer in the span S region and the number of lens pitches P0 of the lens array 4. It can be set by obtaining a difference (absolute value) between P1 and P0 by appropriately setting corresponding to the moire decoration effect.

  In the present invention, the number of moiré (moire fringe) repetitions N is not particularly limited, but when the number of moiré (number of moiré patterns) N is set to N ≦ 1 or less, a moiré pattern is formed. The expression pattern (moire pattern) that appears rough is unclear, and the decorative effect may not be remarkably obtained. In that case, N is set to 1 or more, 1 <N <n (for example, 1.5 <n <10), the moire pattern is made relatively fine, and the expressed moire pattern (moire pattern) appears. ) Can be made clear and a decorative effect can be obtained remarkably.

In the microlens decorative body of the present invention, when the visual expression pattern layer 2 is observed through a micro convex lens array having a one-dimensional arrangement, as shown in a side sectional view of FIG. 1A and a plan view of FIG. The pixels arranged one-dimensionally in the stripe pattern of the visual expression pattern layer 2 are arranged in a state slightly shifted from the positions of the convex lenses 4 arranged one-dimensionally in the stripe pattern of the lens array. As a visual effect due to the deviation, a visual expression pattern is obtained by N (N times) moire fringes (one in the figure) repeated in a one-dimensional direction as shown in the plan view of FIG.

  In the microlens decorative body of the present invention, when the visual expression pattern layer 2 is observed through a micro convex lens array having a two-dimensional arrangement, the plan view of FIG. 2A and the partially enlarged plan view of FIG. As shown, each pixel (for example, circular dot pixel) of the two-dimensionally arranged visual representation pattern layer 2 is arranged in a state of being slightly shifted from the position of each convex lens 4 by the two-dimensional arrangement of the lens array. ing. As a visual effect due to positional deviation, as shown in the plan view of FIG. 2A, each pixel 2 and each lens 4 do not visually overlap each other at all, and each pixel 2 passes through the lens 4. And visible pixel visible region A (pixel portion enlarged view region, circular dot moire fringe) visually overlaps with each other partially or entirely, and each pixel 2 is visible through the lens 4. A pixel invisible region B (a non-pixel portion enlarged view region) that is difficult to perform is formed, and a visual expression pattern is obtained by repeating N moiré fringes in the two-dimensional direction (N times). 2 (a) and 2 (b), pixel visible regions A (circular dotted moire fringes) are generated in a line in the horizontal direction, and θ = 60 ° oblique direction (see FIG. 2 (b)). A visual expression pattern is obtained in a state where approximately two lines are generated side by side.

  FIG. 3 is a microlens decorative body of the present invention, in which (a) is a case where each pixel of the visual expression pattern layer 2 is a round dot-like pixel, and each of the visual expression pattern layers 2 arranged two-dimensionally is shown. The pixels (round dot-like pixels) are arranged in a state where they are slightly shifted with respect to the positions of the convex lenses 4 by the two-dimensional arrangement of the lens array. A visual expression pattern with an enlarged round dot-shaped moire stripe is obtained, and (b) is a case where each pixel of the visual expression pattern layer 2 is a square dot-shaped pixel, and the visual expression pattern layer arranged two-dimensionally 2 pixels (rectangular dot-like pixels) are arranged in a state of being slightly shifted with respect to the position of each convex lens 4 by the two-dimensional arrangement of the lens array. For a square dot moire fringe with a substantially enlarged shape Visual representation pattern is obtained that.

When the oxygen concentration around the decorative body changes due to opening to the atmosphere, each pixel of the visual pattern layer that has disappeared develops color and moire fringes appear, resulting in a visual effect and remarkable visual effects. There was a change. Samples 2 and 3 had a visual effect both in a deoxygenated state while the packaging bag was sealed and in a state opened to the atmosphere, and no change was observed in the visual effect.

Change the visual effect of the decorative bodies of Samples 1 to 3 by putting the micro convex lens decorative bodies of Samples 1 to 3 in an atmosphere of 10 ° C. or lower in a thermostatic bath and changing the temperature from 5 ° C. to 1 ° C. The results of confirming are shown in Table 2.

In Samples 1 to 3, at a temperature of 10 ° C. or less, each pixel 2 of the visual expression pattern layer was colored, and moire fringes were expressed to obtain a visual effect, but Sample 1 was 11 to 19 ° C. The color of each pixel 2 in the visual expression pattern layer gradually fades, and the moire fringes due to each pixel 2 gradually disappear and the visual effect becomes light. At 20 ° C. or higher, each pixel 2 in the visual expression pattern layer disappears. Colored, the visual effect due to the appearance of the moire fringes disappeared, and a noticeable change was seen in the visual effect due to temperature change. Samples 2 and 3 were 11 to 19 ° C. and 20 ° C. or higher, and their visual effects were not changed.

Table 3 shows the results of confirming changes in the visual effects of the decorative bodies of the samples when the manufactured micro convex lens decorative bodies of Samples 1 to 5 were left indoors and left outdoors.

  In Samples 1 and 2, since the amount of infrared light is small indoors, each pixel 2 of the visual expression pattern layer is white, but when left outdoors, Sample 1 changes from white to magenta. The color changed from white to blue, and moire fringes that changed color appeared, and a remarkable visual effect was obtained. In Samples 3, 4, and 5, each pixel 2 of the visual expression pattern layer exhibited red, white, and blue colors indoors. However, even when left outdoors, the pixels 2 did not change color, and moire fringes appeared. However, no remarkable visual effect was obtained.
