Description

The present invention relates to printed matter and decorative materials.

In recent years, from the viewpoint of design, sheets that appear to change in design when the viewing angle is changed have been attracting attention. Hereinafter, the change in the pattern when the viewing angle is changed may be referred to as "flip".

Holograms are generally used as a method for expressing a flipping design. However, holograms have problems that the manufacturing process is complicated and costly, and that they are not suitable for manufacturing small-lot, high-mix products.
For example, the technique of Patent Document 1 has been proposed as one that can solve the above problem.

Japanese Unexamined Patent Publication No. 10-147098

Patent Document 1 has a brilliant pattern layer containing a scaly foil piece of a light-reflecting substance and a colored transparent resin layer in this order on a base material, and has a mirror gloss with an incident angle of 20 to 60 °. We have proposed a decorative sheet in which the glittering pattern layer can be seen or not seen depending on the viewing angle by lowering the mirror glossiness of the bright pattern layer than the mirror gloss of the colored transparent resin layer.

The decorative material of Patent Document 1 can exhibit a certain level of flip.
However, in the decorative material of Patent Document 1, the reflectance of the colored transparent resin layer can be expected to be only about 5% (the reflectance of a normal resin is about 5%), and the mirror glossiness of the glittering pattern layer is high. Because it was designed to be lower than the mirror gloss of the colored transparent resin layer, the pattern felt dim.
Further, in the decorative material of Patent Document 1, it cannot be said that the glittering pattern layer cannot be seen. That is, when the reflectance of the light reflected by the colored transparent resin layer of the decorative material of Patent Document 1 is X, and the reflectance of the light transmitted through the colored transparent resin layer and reflected by the brilliant pattern layer is Y, it is brilliant. This is because the portion having the sex pattern layer has a larger amount of reflected light by the amount of the reflectance Y than the portion having no glittering pattern layer, and a contrast is generated in both portions.
Therefore, it cannot be said that the decorative material of Patent Document 1 has a sufficiently high design.

An object of the present invention is to provide a printed matter and a decorative material which can express a flipping design by a simple method and have excellent designability.

In order to solve the above problems, the present invention provides the following [1] to [2].

<Principle of flip>
The reason why the flipping design can be observed in the printed matter of the present invention will be described.
First, as shown in FIG. 6, it is assumed that light is incident on the surface of the printed matter 100 from the direction of the arrow. Further, in the printed matter 100 of FIG. 6, the first reflection layer 40 is a layer having a weak directionality of diffuse reflection (a layer that diffusely reflects over a wide angle range), and the second reflection layer 50 is a layer having a strong directionality of diffuse reflection. It will be described as being (a layer that diffusely reflects in a narrow angle range).
FIG. 7 shows the printed matter 100 from the direction (i) (direction in which light is incident), the direction (ii), and the direction (iii) (direction of specular reflection of incident light) in FIG. 6 under the above preconditions. It is a figure which shows the intensity of the reflected light of three layers (the pearl layer 30, the first reflection layer 40 and the second reflection layer 50) in each direction when visually recognizing. In FIG. 7, the solid line arrow indicates the reflected light intensity of the pearl layer 30, the one-point chain line arrow indicates the reflected light intensity of the first reflective layer 40, the dotted arrow indicates the reflected light intensity of the second reflective layer 50, and the arrow is long. It shows that the reflected light intensity is stronger. Further, FIG. 7A shows the reflection intensity at the portion having the first reflection layer 40, and FIG. 7B shows the reflection intensity at the portion without the first reflection layer 40.

Comparing FIGS. 7 (a) and 7 (b), it can be seen that the reflection intensity of the pearl layer 30 is the same in all directions. Further, it can be seen that the reflection by the pearl layer 30 is dominated by the substantially specular reflection.

Further, when FIG. 7 (a) and FIG. 7 (b) are compared, it can be seen that FIG. 7 (a) has a higher reflection intensity in the direction of (i) and the direction of (ii).
In FIG. 7A, the reason why the reflection intensity in the direction (i) and the direction (ii) is large is that the first reflective layer 40 has a weak directivity of diffuse reflection, and the incident light is reflected in a wide angle range. Because. Further, in the place where the first reflection layer 40 is not provided, the reflection by the second reflection layer 50 occurs, but the second reflection layer has a strong directivity of diffuse reflection, and the reflection is dominated by the specular reflection. Therefore, in the place where the first reflection layer 40 is not provided, the reflection intensity in the direction (i) and the direction (ii) becomes small. Therefore, in the direction (i) and the direction (ii), the difference in the reflection intensity between the portion having the first reflective layer and the portion not having the first reflective layer becomes large, and the pattern of the first reflective layer 40 becomes large. Will be visible.
On the other hand, in the direction of (iii), it can be seen that the difference between the total reflected light intensity of each layer of FIG. 7 (a) and the total reflected light intensity of each layer of FIG. 7 (b) is small. The reflection by the pearl layer 30 plays an important role in reducing this difference (in the absence of the reflection of the pearl layer 30, the reflection intensity of the first reflection layer 40 and the reflection intensity of the second reflection layer 50). The difference becomes more noticeable). Therefore, in the direction of (iii), it becomes difficult to recognize the difference in brightness between the portion having the first reflective layer 40 and the portion not having the first reflective layer 40, and the pattern of the first reflective layer 40 can be visually recognized. It becomes difficult to be done.

As described above, under the above preconditions, the pattern of the first reflective layer 40 is difficult to be visually recognized in the direction (i) and (ii), and the pattern of the first reflective layer 40 is difficult to be visually recognized in the direction (iii). As a result, the flipping design can be observed.
Under the above preconditions, the first reflective layer is a layer with a weak diffuse reflection directional, and the second reflective layer is a layer with a strong diffuse reflection directional, but the first reflective layer is diffused. The same effect can be obtained even when the layer has a strong reflection directional and the second reflection layer has a weak diffuse reflection directional. In this case, the negative pattern of the first reflective layer 40 is visually recognized in the direction (i) and (ii), and the negative pattern of the first reflective layer 40 is difficult to be visually recognized in the direction of (iii), resulting in flipping. You will be able to observe the design.

In the above description, the case where a layer having a strong diffuse reflection direction in the normal reflection direction is used as an example of a layer having a strong diffuse reflection directivity has been described as an example, but the incident is incident as a layer having a strong diffuse reflection directivity. Even when a layer with strong directional diffuse reflection in the direction (retroreflective layer) is used, the flipping design can be observed.
Further, as a combination in which the directivity of the diffuse reflection is different, it is possible to combine a layer having a strong directivity of the diffuse reflection in the specular reflection direction and a layer having a strong directivity of the diffuse reflection in the incident direction.
That is, examples of combinations having different directivity of diffuse reflection include the following (A) to (F).

(A) The first reflective layer is a layer with weak diffuse reflection directivity, the second reflective layer is a layer with strong diffuse reflection directivity in the normal reflection direction (the first reflective layer is strongly diffused, and the second reflective layer is positive. Reflection)
(B) The first reflective layer is a layer with strong diffuse reflection in the normal reflection direction, the second reflective layer is a layer with weak diffuse reflection directivity (the first reflective layer is positive reflection, the second reflective layer is strong). diffusion)
(C) The first reflective layer is a layer with weak diffuse reflection directivity, the second reflective layer is a layer with strong diffuse reflection directivity in the incident direction (the first reflective layer is strongly diffuse, and the second reflective layer is retroreflection. )
(D) The first reflective layer is a layer with a strong directivity of diffuse reflection in the incident direction, the second reflective layer is a layer with a weak directivity of diffuse reflection (the first reflective layer is retroreflective, the second reflective layer is strongly diffused). )
(E) The first reflection layer is a layer having a strong direction of diffuse reflection in the normal reflection direction, and the second reflection layer is a layer having a strong direction of diffuse reflection in the incident direction (the first reflection layer is a normal reflection, the second is a layer. Reflective layer is retroreflective)
(F) The first reflective layer is a layer with strong diffuse reflection in the incident direction, the second reflective layer is a layer with strong diffuse reflection in the normal reflection direction (the first reflective layer is retroreflective, the second). Reflective layer is normal reflection)

FIG. 9 shows a case where the first reflection layer is a layer having a weak directionality of diffuse reflection and the second reflection layer is a layer having a strong directionality of diffuse reflection in the incident direction (configuration of (C) above). When light is incident from the direction of the arrow in FIG. 6, the direction (i) (direction in which the light is incident), the direction (ii), and the direction (iii) (direction of normal reflection of the incident light) in FIG. ) Shows the intensity of the reflected light of the three layers (pearl layer 30, first reflective layer 40, and second reflective layer 50) in each direction when the printed matter 100 is visually recognized.
In FIG. 9, the thin solid line arrow indicates the reflected light intensity of the pearl layer 30, the one-point chain line arrow indicates the reflected light intensity of the first reflective layer 40, and the thick solid line arrow indicates the reflected light intensity of the second reflective layer 50. The longer the value, the stronger the reflected light intensity. Further, FIG. 9A shows the reflection intensity at the portion having the first reflection layer 40, and FIG. 9B shows the reflection intensity at the portion without the first reflection layer 40.
In the configuration of the above configuration (C), the negative pattern of the first reflective layer is observed in the direction of (i), and the pattern of the first reflective layer is observed weakly in the directions of (ii) and (iii) (). The directions of (ii) and (iii) are slightly different). In the configuration of (C) above, although the pattern is observed to change constantly and a flip is expressed, there is no moment when the pattern is almost invisible.

FIG. 10 shows a case where the first reflection layer is a layer having a strong directivity of diffuse reflection in the normal reflection direction, and the second reflection layer is a layer having a strong directivity of diffuse reflection in the incident direction ((E) above). In (configuration), when light is incident from the direction of the arrow in FIG. 6, the direction (i) (direction in which the light is incident), the direction (ii), and the direction (iii) (incident light) in FIG. The intensity of the reflected light of the three layers (pearl layer 30, first reflection layer 40, and second reflection layer 50) in each direction when the printed matter 100 is visually recognized from the direction of normal reflection).
In FIG. 10, the thin solid line arrow indicates the reflected light intensity of the pearl layer 30, the dotted line arrow indicates the reflected light intensity of the first reflective layer 40, the thick solid line arrow indicates the reflected light intensity of the second reflective layer 50, and the arrow indicates the reflected light intensity. The longer it is, the stronger the reflected light intensity is. Further, FIG. 10A shows the reflection intensity at the portion having the first reflective layer 40, and FIG. 10B shows the reflection intensity at the portion without the first reflective layer 40.
In the configuration of the above configuration (E), the negative pattern of the first reflective layer is observed in the direction of (i), and the pattern of the first reflective layer is observed in the direction of (iii), while the pattern of the first reflective layer is observed, while the pattern of (ii) is observed. In the direction, the pattern is less likely to be observed, and a flip can be expressed. Further, in the configuration of (E) above, the brightness of the observed pattern is high.

Among the above (A) to (F), (A), (B), (E) and (F) are suitable in that the pattern is almost invisible in any direction and the flip effect is high. In particular, (A) and (B) are preferable from the viewpoint of easily and stably producing printed matter that expresses flip.

<Pearl layer>
The pearl layer is a layer containing a pearl pigment. Further, among the pearl layer, the first reflective layer and the second reflective layer, the pearl layer is arranged on the viewer side of the printed matter.
Examples of the pearl pigment include thin plate-like fine particles having a coating layer made of a high-refractive index material such as titanium dioxide on the surface of the scale-like fine particles of mica, and have light transmittance. Therefore, by including the pearl pigment in the pearl layer, light is reflected multiple times, a glossy feeling like metal or pearl can be given to the printed matter, and the distance of the light passing through the pearl layer increases or decreases depending on the angle. As a result, the degree of multiple reflection changes, so that the design can be improved. Further, the presence of the pearl layer alleviates the difference in color and gloss between the portion having the first reflective layer and the portion not having the first reflective layer, and suppresses the constant observation of the pattern. You can also do it.
Further, as described above, with respect to the configurations of (A) and (B), the pearl layer has the reflection intensity between the portion having the first reflective layer and the portion not having the first reflective layer in the specular reflection direction. It plays an important role in reducing the difference and expressing flips.

There are several types of pearl pigments, and they can be roughly classified into three types: white pearl pigments, interference pearl pigments and colored pearl pigments.
In the white pearl pigment, the coating layer of the mica is a colorless high refractive index material such as titanium dioxide, and the thickness of the coating layer is relatively thin, about 0.1 to 0.15 μm, and almost all wavelengths of light are used. It looks white or silver because it reflects.
In the interference pearl pigment, the coating layer of the mica is a colorless high refractive index material such as titanium dioxide, and the thickness of the coating layer is thicker than that of the white pearl pigment, which is more than 0.15 μm. In the interference pearl pigment, the reflected light and the transmitted light change depending on the thickness of the coating layer, and various interference colors are generated. Interfering pearl pigments are sometimes referred to as iridescent pearl pigments.
The colored pearl pigment is chromatic, and the coating layer of the mica is made of a colored high refractive index material such as ferric oxide, and the periphery of the white pearl pigment is further colored high refractive index material such as ferric oxide or others. There are those coated with the colored pigments of the above, and those in which pigments and other colorants are added to the coating layer of the mica.

The pearl pigment may be of any type, but the white pearl pigment and the interfering pearl pigment absorb less light of the pearl pigment itself, so that the brightness of the printed matter can be increased and the above (A) and (B) can be increased. It is preferable in that the difference in the reflection intensity between the portion having the first reflective layer and the portion not having the first reflective layer can be easily reduced in the normal reflection direction, and the flip is easily generated.

The average particle size of the pearl pigment is not particularly limited, and is preferably 3 to 60 μm, more preferably 5 to 40 μm, and even more preferably 10 to 30 μm. In the present specification, the average particle size of the pearl pigment refers to the average value of the major axis of any 20 particles observed with an optical microscope.

The content of the pearl pigment is preferably 10 to 60% by mass, more preferably 15 to 50% by mass, and further preferably 20 to 40% by mass of the total solid content of the pearl layer.
By setting the content of the pearl pigment to 10% by mass or more, it is possible to easily impart a glossy feeling like metal or pearl, and it is possible to easily develop a flip with respect to the configurations (A) and (B). Further, by setting the content of the pearl pigment to 60% by mass or less, the amount of light reaching the first reflective layer and the second reflective layer can be made sufficient to facilitate flipping, and the decrease in coating film strength can be suppressed. can.

The thickness of the pearl layer is preferably 0.2 to 20 μm, more preferably 0.5 to 10 μm, and even more preferably 0.5 to 3 μm.
By setting the thickness of the pearl layer to 0.2 μm or more, it is possible to easily impart a glossy feeling like metal or pearl, and it is possible to easily develop flips with respect to the configurations (A) and (B). Further, by setting the thickness of the pearl layer to 20 μm or less, the amount of light reaching the first reflective layer and the second reflective layer can be made sufficient, and flip can be easily expressed.
The thickness of the pearl layer and the first reflective layer and the second reflective layer, which will be described later, can be calculated from, for example, an image of a cross-sectional photograph of a printed matter and an average value of 10 arbitrary points.

The pearl layer preferably contains a binder resin.
The binder resin is a polyolefin resin such as a polyethylene resin or a chlorinated polypropylene resin, a poly (meth) acrylic resin, a polyvinyl chloride resin, a polyvinyl acetate resin, a vinyl chloride-vinyl acetate copolymer, or a polystyrene resin. Resin, styrene-butadiene copolymer, vinylidene fluoride resin, polyvinyl alcohol resin, polyvinyl acetal resin, polyvinyl butyral resin, polybutadiene resin, polyester resin, polyamide resin, alkyd resin, epoxy resin, Unsaturated polyester resin, heat-curable poly (meth) acrylic resin, melamine resin, urea resin, polyurethane resin, phenol resin, xylene resin, maleic acid resin, nitrocellulose, ethyl cellulose, acetylbutyl cellulose, One or more selected from fibrous resins such as ethyloxyethyl cellulose, rubber resins such as rubber chloride and cyclized rubber, petroleum resins, and natural resins such as rosin and casein can be mentioned.

Fillers, stabilizers, plasticizers, antioxidants, light stabilizers, ultraviolet absorbers, and dispersions are contained in the pearl layer, as well as the first reflective layer, the second reflective layer, the concealing layer, the colored layer, and the protective layer, which will be described later. Any additives such as agents, thickeners, desiccants, lubricants and antistatic agents can be added.

The pearl layer may be formed on the entire surface of the printed matter, or may be formed in a striped shape or the like on a part of the printed matter. When the pearl layer is formed on the entire surface of the printed matter, the above-mentioned effect can be imparted to the entire surface of the printed matter. On the other hand, when the pearl layer is formed on a part of the printed matter, the visual effect between the portion having the pearl layer and the portion not having the pearl layer can be changed, and a design rich in variation can be imparted.

<First reflective layer, second reflective layer>
The first reflective layer 40 has an arbitrary pattern.
The arbitrary pattern is not particularly limited, and examples thereof include a wood grain pattern, a stone grain pattern, a tiled pattern, a brickwork pattern, a fabric pattern, and a geometric pattern. The pattern in FIG. 8 is a striped pattern.

The second reflective layer 50 is arranged at least a part of a portion of the first reflective layer 40 that does not have a pattern when the printed matter 100 is viewed in a plan view from the pearl layer 30 side, and the first reflective layer 40 is arranged. It is preferable that they are arranged in all the places that do not have the pattern of.
The second reflective layer is arranged on the entire surface of the first reflective layer 40 on the opposite side of the pearl layer 30, as shown in FIGS. 1 and 3 to 5, or as shown in FIG. 2, the first reflective layer is arranged. It can be arranged in the gap of the pattern of the layer 40. From the viewpoint of easily and stably producing a printed matter satisfying a predetermined performance, it is preferable to arrange the second reflective layer on the entire surface opposite to the pearl layer of the first reflective layer.

In the printed matter of the present invention, it is preferable that the first reflective layer and the second reflective layer are a combination of any of the above (A) to (F).
The above (A) to (F) are a combination of three types: a layer having a weak diffuse reflection directivity, a layer having a strong diffuse reflection directivity in the specular reflection direction, and a layer having a strong diffuse reflection directivity in the incident direction. The first reflective layer and the second reflective layer are formed.
Examples of the layer having a weak directivity of diffuse reflection include a layer containing diffuse reflection particles.
Examples of the layer having a strong directivity of diffuse reflection in the specular reflection direction include a layer containing metal scales or a metal film.
Examples of the layer having a strong directivity of diffuse reflection in the incident direction include a layer containing retroreflective particles.

<< Layer containing diffuse reflection particles >>
Examples of the diffuse reflection particles include white pigments such as titanium dioxide, barium sulfate, magnesium oxide, calcium carbonate, zinc oxide, and white lead, and one or more of these can be used.
The shape of the diffuse reflection particles is preferably spherical from the viewpoint of facilitating diffuse reflection in all directions.

The average particle size of the diffuse reflection particles is preferably 0.1 to 10 μm, more preferably 0.5 to 5 μm, and even more preferably 0.5 to 3 μm.
In the present specification, the average particle size of the diffusely reflected particles and the retroreflected particles described later is 50% particles when the particles dispersed in the solution are measured by a dynamic light scattering method and the particle size distribution is expressed as a cumulative distribution. The diameter (d50: particle diameter). The 50% particle size can be measured using, for example, a Microtrac particle size analyzer (manufactured by Nikkiso Co., Ltd.).

The content of the diffuse reflection particles is preferably 1 to 60% by mass, more preferably 5 to 50% by mass, and 10 to 40% by mass of the total solid content of the layer containing the diffuse reflection particles. Is even more preferable.
By setting the content of the diffuse reflection particles to 1% by mass or more, the reflection intensity of the layer containing the diffuse reflection particles can be increased, and flips can be easily expressed. Further, by setting the content of the diffuse reflection particles to 60% by mass or less, it is possible to suppress a decrease in the strength of the coating film.

The thickness of the layer containing the diffuse reflection particles is preferably 0.2 to 20 μm, more preferably 0.5 to 10 μm, still more preferably 0.5 to 3 μm.
By setting the thickness of the layer containing the diffuse reflection particles to 0.2 μm or more, the reflection intensity of the layer containing the diffuse reflection particles can be increased, and flips can be easily expressed. Further, by setting the thickness of the layer containing the diffuse reflection particles to 20 μm or less, the printed matter can be easily made into a thin film.

The layer containing the diffuse reflection particles preferably contains a binder resin. As the binder resin, the same binder resin as that of the pearl layer can be used.

<< Layer containing metal scales >>
Examples of the material of the metal scale include metals and alloys such as aluminum, gold, silver, brass, titanium, chrome, nickel, nickel chrome, and stainless steel. Among these, aluminum, silver, and nickel are preferable because they tend to make the pattern invisible in the specular reflection direction more reliable by making the color tint closer to that of the layer containing the diffuse reflection particles.

The metal scales preferably have an average length of 1 to 30 μm, more preferably 2 to 20 μm, from the viewpoint of dispersibility and arrangement in the layer.
Further, from the viewpoint of arrangement in the layer, the average thickness of the metal scales is preferably 0.50 μm or less, more preferably 0.10 μm or less, still more preferably 0.08 μm or less. It is more preferably 0.05 μm or less. The average thickness of the metal scales is preferably 0.01 μm or more, more preferably 0.02 μm or more, from the viewpoint of handleability and gloss.

The average length and the average thickness of the metal scales shall be the average value of 20 metal scales. The length and thickness of each metal scale can be measured by using a laser interferometry type three-dimensional shape analysis device with the metal scale scattered on a smooth base material. The length of each metal scale means the maximum diameter when the individual metal scale is observed from a plane in any direction, and the thickness of the individual metal scale is the thickness when the individual metal scale is observed from the cross-sectional direction. It means the maximum thickness. The maximum diameter when observing individual metal scales from a plane in an arbitrary direction is intended to unify the direction in which the maximum diameter of each metal scale is measured. For example, when the X-axis direction on the image-processed screen of the measurement result of the three-dimensional shape analysis device is an arbitrary direction (measurement direction), the maximum diameter is measured in a direction parallel to the X-axis. Even if the maximum diameter exists in a direction that is not parallel to the X-axis, it is not regarded as the maximum diameter.
Examples of the laser interference type three-dimensional shape analysis device include the trade name “Shape Analysis Laser Microscope VK-X Series” manufactured by KEYENCE CORPORATION.

The metal scale can be obtained, for example, by peeling a metal thin film formed by vacuum-depositing the metal or alloy on a plastic film from the plastic film, and crushing and stirring the peeled metal thin film.

The content of the metal scales is preferably 5% by mass or more and 40% by mass or less, more preferably 5% by mass or more and 35% by mass or less, and further preferably 10% by mass or more of the total solid content of the layer containing the metal scales. It is 30% by mass or less.
By setting the content of the metal scales to 5% by mass or more, it is possible to easily improve the concealing property and glossiness of the printed matter, and it is possible to easily develop flip. Further, by setting the content of the metal scales to 40% by mass or less, it is possible to suppress a decrease in the strength of the coating film.

The thickness of the layer containing the metal scales is preferably 0.2 to 20 μm, more preferably 0.5 to 10 μm, still more preferably 0.5 to 3 μm.
By setting the thickness of the layer containing the metal scales to 0.2 μm or more, it is possible to easily improve the concealing property and glossiness of the printed matter, and it is possible to easily develop flip. Further, by setting the thickness of the layer containing the metal scales to 20 μm or less, the printed matter can be easily thinned, and the printed matter has a portion having the first reflective layer and a first reflective layer with respect to the configurations of (A) and (B).
