That is, the scale of each layer constituting the shaped sheet 10 and the scale of the surface unevenness are simplified for ease of illustration, and are different from the actual scale. The figures other than FIG. 1 are also different from the actual scale.

Examples of the material constituting the base material include paper, nonwoven fabric, woven fabric, resin, and the like.

Examples of the paper base material include kraft paper, titanium paper, linter paper, parchment paper, glassine paper, parchment paper, resin-impregnated paper, thin paper, and Japanese paper.
The fibers that make up the base material of nonwoven or woven fabrics include inorganic fibers made of inorganic materials such as glass, alumina, silica, and carbon; organic fibers made of synthetic resins such as polyester resin, acrylic resin, polyethylene, and polypropylene. One or more types selected from fibers and the like can be mentioned.

Resin base materials include polypropylene, polyethylene, polyolefin thermoplastic elastomers, polyolefin resins such as ionomers, polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyethylene naphthalate (PEN), ethylene glycol-terephthalic acid-isophthalic acid. Copolymers, polyester resins such as polyester thermoplastic elastomers, acrylic resins such as polymethyl (meth)acrylate, polybutyl (meth)acrylate, methyl (meth)acrylate-butyl (meth)acrylate copolymers, polyester resins, polycarbonate resins , acrylonitrile-butadiene-styrene resin, vinyl chloride resin, and the like.

The base material may contain additives such as colorants, flame retardants, antioxidants, lubricants, foaming agents, antioxidants, ultraviolet absorbers, and light stabilizers.

The base material may be one type of base material alone, or may be a composite base material in which two or more types of base materials are laminated.

The thickness of the base material is not particularly limited and may be appropriately determined depending on the performance that is important.
In the case of a resin base material, the lower limit of the thickness is preferably 20 μm or more, more preferably 40 μm or more, and the upper limit is preferably 300 μm or less, more preferably 200 μm or less, and still more preferably 100 μm or less.
In the case of a paper base material, the basis weight is preferably 20 g/m ² or more and 150 g/m ² or less, more preferably 30 g/m ² or more and 100 g/m ² or less.

The base material has been subjected to a physical surface treatment such as an oxidation method, a roughening method, or a chemical surface treatment on one or both sides in order to improve the adhesion with the matte layer, etc. It's okay. Furthermore, a primer layer may be provided between the base material and the matte layer.

<Matte layer>
The shaped sheet of the present disclosure has a matte layer on the base material.
Although the matte layer may be formed on a part of the base material, it is preferably formed on the entire surface of the base material.

The surface of the matte layer side of the shaped sheet of the present disclosure has a maximum height roughness Rz of 2.5 μm or more as defined in JIS B0601:2013, and a roughness curve element as defined in JIS B0601:2013. The average length RSm is required to be 50.0 μm or less.
The region in which Rz is 2.5 μm or more and RSm is 50.0 μm or less may be a part of the surface of the matte layer side of the molding sheet; Preferably, the entire surface area of .

The surface of the matte layer side of the shaping sheet having Rz of 2.5 μm or more and RSm of 50.0 μm or less has good antireflection properties. In addition, the surface shape of the decorative material shaped by the shaping sheet becomes a complementary shape to the surface shape of the matte layer (depending on conditions such as heat and pressure during shaping, the surface shape of the decorative material and the matte layer The surface shape of the matte layer may not be in a completely complementary relationship.However, the surface shape of the decorative material and the surface shape of the matte layer can be said to be in a substantially complementary relationship.) Therefore, the values of Rz and Rsm of the decorative material are approximately the same as the values of Rz and Rsm of the surface of the shaped sheet on the matte layer side. Therefore, when the surface of the matte layer side of the shaping sheet has Rz of 2.5 μm or more and RSm of 50.0 μm or less, the antireflection properties of the decorative material can be improved.
A shape in which Rz is 2.5 μm or more and RSm is 50.0 μm or less is considered to have good antireflection properties because it can reduce the proportion of light reflected in the specular direction of reflected light. .
Even if Rz is 2.5 μm or more, if RSm exceeds 50.0 μm, it is not possible to reduce the proportion of light reflected in the specular reflection direction, making it impossible to improve antireflection properties. In addition, even if RSm is 50.0 μm or less, if Rz is less than 2.5 μm, it is not possible to reduce the proportion of light reflected in the specular direction, so it is not possible to improve antireflection properties. .

On the surface of the shaped sheet on the matte layer side, Rz is preferably 3.0 μm or more, more preferably 3.5 μm or more, and even more preferably 4.0 μm or more.
If Rz becomes too large, the reflected light is likely to be scattered at various angles, causing the object to be formed to look whitish, and the design of the object to be formed may deteriorate. Therefore, on the surface of the matte layer side of the shaping sheet, Rz is preferably 10.0 μm or less, more preferably 8.0 μm or less, and even more preferably 6.0 μm or less.

On the surface of the shaped sheet on the matte layer side, RSm is preferably 45.0 μm or less, more preferably 40.0 μm or less, and even more preferably 35.0 μm or less.
If RSm becomes too small, the reflected light tends to be scattered at various angles, so that the object to be molded looks whitish, and the design of the object to be molded may deteriorate. Therefore, on the surface of the matte layer side of the shaping sheet, RSm is preferably 5.0 μm or more, more preferably 7.5 μm or more, even more preferably 10.0 μm or more, and 20 μm or more. It is even more preferable that the thickness is .0 μm or more.

In this specification, Rz, RSm, and Ra, which will be described later, can be measured, for example, as shown in A1 to A3 below.
A1: The surface shape of the matte layer side of the molded sheet is measured using a laser microscope. The measurement area is preferably 204 μm long x 272 μm wide. It is preferable that the objective lens of the laser microscope has a magnification of 50 times.
A2: In the measurement area, obtain 8 cross sections in the vertical direction and 7 cross sections in the horizontal direction. The interval between the acquired cross sections may be set as appropriate within a range that does not make the interval too narrow. Rz, RSm, and Ra are calculated at 15 cross sections. Then, the average values of the cross sections at 15 locations are defined as Rz, RSm, and Ra in the measurement area (204 μm in length x 272 μm in width). When calculating Rz, RSm, and Ra, the value corresponding to the cutoff value λc is preferably set to 0.8 mm.
A3: Perform the operations (1) and (2) above in nine measurement areas (204 μm in length x 272 μm in width). Then, the average values of the nine measurement areas are defined as Rz, RSm, and Ra of the shaping sheet.

The surface of the matte layer side of the shaped sheet of the present disclosure preferably has an arithmetic mean roughness Ra defined in JIS B0601:2013 of 0.1 μm or more and less than 2.5 μm. Ra is more preferably 0.3 μm or more and 2.0 μm or less, even more preferably 0.5 μm or more and 1.5 μm or less, even more preferably 0.6 μm or more and 1.0 μm or less.
By setting Ra to 0.1 μm or more, antireflection properties can be easily improved. By setting Ra to less than 2.5 μm, it is possible to more easily suppress deterioration in the design of the object to be formed due to the object to be formed looking whitish.

The matte layer side surface of the shaped sheet of the present disclosure preferably has an RSm/Ra of 60.0 or less, more preferably 50.0 or less, and even more preferably 45.0 or less. . By setting RSm/Ra to 60.0 or less, antireflection properties can be easily improved.
If RSm is less than a predetermined value and RSm/Ra is too small, the object to be imprinted may appear whitish. Therefore, RSm/Ra is preferably 10.0 or more, more preferably 20.0 or more, and even more preferably 30.0 or more.

It is preferable that the surface of the shaped sheet on the matte layer side has an uneven shape constituted by irregular wrinkles. By having an uneven shape constituted by irregular wrinkles, Rz and RSm can be easily set within the above ranges. However, in order to easily keep Rz and RSm within the above ranges, it is not enough to simply form wrinkles; it is important to form wrinkles with a fine pitch and high altitude.
Note that the conventional general-purpose matte layer contains a binder resin and a matting agent, and exhibits a matting effect due to surface irregularities caused by the matting agent. With such a conventional general-purpose matte layer, unevenness due to wrinkles cannot be formed on the surface, and it is difficult to keep Rz and RSm within the above ranges.

Examples of aspects related to wrinkles include the aspect shown in FIG. 2, for example.
FIG. 2 shows that the surface of the matte layer side of the molded sheet 10 has irregular wrinkles in plan view. In addition, in FIG. 2, irregular wrinkles are formed by a plurality of convex portions 3 formed by a plurality of curved linear protrusions, and a concave portion 2 formed by being surrounded by a plurality of protrusions (a plurality of convex portions 3). It is shown that it is constituted by including. In addition, in FIG. 2, at least a portion of the plurality of curved convex portions 3 are each formed by a meandering linear protrusion, and the meandering concave portion 2 is formed so as to be surrounded by the meandering linear protrusion. It is also shown that

Here, "curved" means having one or more portions where the extending direction of the continuous filamentous convex portions 3 is reversed from one side to the other side in plan view. As an example of a portion where the extending direction is reversed from one side to the other side, for example, when the width of the planar view shape of the linear convex portion 3 is assumed to be 0 and approximated by a continuous curve, the continuous curve is Examples include a form having an inflection point. In addition, when the width of the planar view shape of the linear convex portion 3 is ignored and approximated by a straight line, a form having a portion approximated by a V-shaped broken line or two sides sandwiching one vertex of a triangle, etc. Can be mentioned.
Furthermore, "meandering" refers to a portion where the extending direction of the convex portions 3 of continuous filaments is reversed from one side to the other side (hereinafter also referred to as "reversed portion") in plan view. or more, and when the filament convex part 3 is advanced in its extending direction, the extending direction of the filament convex part 3 is alternately reversed in two adjacent places. It means to have. For example, when the width of the linear convex portion 3 in plan view is approximated by a continuous curve, there is a form having a portion approximated by the Roman letter "S". Further, when the width of the linear convex portion 3 in plan view is approximated by a straight line, there may be a form having a portion approximated by the Roman letter "W".

In this specification, irregular means a shape that has a certain rule or a pattern that is not arranged according to a certain rule. A typical example of a non-irregular shape (regular shape) is a so-called "lenticular lens" in which a plurality of cylindrical unit lenses are arranged adjacent to each other in a direction perpendicular to the longitudinal direction. Examples include shapes arranged with a certain periodicity in a specific direction. Therefore, the irregular wrinkles in this embodiment are caused by the fact that the shape of one protrusion itself is not a shape that is formed according to a certain rule such as periodicity, but is irregular, and that the shape of a single protrusion itself is not formed according to a certain rule such as periodicity, but is irregular. This includes the fact that the shape of the protrusions is irregular rather than being formed and arranged according to a certain rule, and that the shape of the recess surrounded by a plurality of such protrusions is also irregular. be.
In the matte layer of the shaped sheet of the present disclosure, the shape itself of one protrusion (one protrusion), the shape and arrangement of each of the plurality of protrusions (the plurality of protrusions), and the shape of the protrusion surrounded by the plurality of protrusions. Any of the shapes of the recessed portions may be irregular, but it is preferable that all of the shapes be irregular. Irregular wrinkles prevent reflected light from being biased toward a specific angle, making it easier to improve antireflection properties.

As mentioned above, the surface of the matte layer preferably has an uneven shape constituted by irregular wrinkles. The convex portions and concave portions in the uneven shape are based on the median value of the height distribution in the concave and convex shape, and a region with a height exceeding the median value is defined as a convex portion, and a region with a height below the median value is defined as a concave portion. For example, by using the density difference (that is, the brightness difference) of an image having a density corresponding to the height of the surface of the matte layer of this embodiment, the darkest part in the density distribution image is set to gradation 255, and the density distribution image is The thinnest part is taken as gradation 0 (the intermediate value of density corresponding to the intermediate value of height is 127), and for gradation 0 to 255, gradation 0 to 127 is a concave part, and gradation 128 to 255 is a convex part. , they can be divided by binarization processing.

It is preferable that irregular wrinkles are formed on at least a portion of the surface of the shaped sheet of the present disclosure on the matte layer side, and more preferably that irregular wrinkles are formed over the entire surface.
Further, as shown in FIG. 2, it has a plurality of protrusions formed by a plurality of irregular but uniform protrusions, and a recess surrounded by the protrusions. It is preferable. Therefore, a shape in which the width of one convex portion (protrusion) changes drastically is unlikely to have the above-mentioned surface shape. The shapes of the convex portions (protrusions) and concave portions that form irregular wrinkles will be specifically explained below.

Regarding the shape of the wrinkles formed on the surface of the matte layer side, the height of the protrusions (height of the protrusions) is preferably 0.5 μm or more, more preferably 1 μm or more, and still more preferably 2 μm or more, The upper limit is about 10 μm or less. Further, the width of the convex portion is preferably 0.1 μm or more, more preferably 0.3 μm or more, even more preferably 0.5 μm or more, and the upper limit is preferably 10 μm or less, more preferably 4 μm or less, and still more preferably 3 μm. It is as follows. When the height and width of the convex portion are within the above range, the surface shape described above is easily exhibited.
Here, the above-mentioned dimensions of the protrusions are the average of ten arbitrary protrusions (protrusions) at ten arbitrary locations (100 μm square area x 10 locations) of the imprinted sheet of the present disclosure, that is, a total of 100 protrusions. It is a value. In addition, as shown in FIG. 2, the width of one convex part (protrusion) is not the same and is wide and narrow, so the width of one convex part (protrusion) is ) is the average value of the widths at five arbitrary locations. The same applies to the height of the convex portion (protrusion).

The depth of the recess is preferably 0.5 μm or more, more preferably 1 μm or more, even more preferably 2 μm or more, and the upper limit is about 10 μm or less. Further, the width of the recess is preferably 0.1 μm or more, more preferably 0.2 μm or more, and still more preferably 0.3 μm or more, and the upper limit is preferably 10 μm or less, more preferably 3 μm or less, and even more preferably 2 μm or less. It is. When the depth and width of the recesses are within the above ranges, the surface shape described above is likely to be exhibited. The dimensions of the concave portion are determined in the same manner as the dimensions of the convex portion described above.

The distance from the top of the convex part to the bottom of the concave part (difference in height between the convex part and the concave part) is preferably 1 μm or more, more preferably 2 μm or more, even more preferably 4 μm or more, and the upper limit is preferably 20 μm or less, more preferably Preferably it is 8 μm or less, more preferably 7 μm or less. When the distance is within the above range, the surface shape described above is likely to be exhibited.

The occupation ratio of the convex portion is preferably 15% or more, more preferably 20% or more, even more preferably 30% or more, and the upper limit is preferably 80% or less, more preferably 70% or less, and still more preferably 60% or less. It is. When the occupation ratio of the convex portions is within the above range, the above surface shape is likely to be exhibited.
Here, the occupancy rate of the convex portions is the average value of the occupancy rate of the convex portions at arbitrary 10 locations (100 μm square area x 10 locations) on the shaped sheet of the present disclosure.

The convex portion and the concave portion may have portions having substantially the same direction and substantially the same width, but in order to improve antireflection properties, it is preferable that the length thereof be short. Specifically, the continuous length of convex portions and concave portions having approximately the same direction and approximately the same width is preferably 95 μm or less, more preferably 80 μm or less, and even more preferably 70 μm or less, and the lower limit is preferably 5 μm or more, More preferably, it is 10 μm or more, and still more preferably 15 μm or more. When the length is within the above range, the wrinkles become more irregular, making it easier to improve the antireflection properties.
Here, 80% or more of arbitrary ten convex portions and concave portions (i.e., a total of 100 convex portions and concave portions) at ten arbitrary locations (100 μm square area x 10 locations) of the shaped sheet of the present disclosure It is preferable that it satisfies the following conditions, more preferably 85% or more, still more preferably 90% or more, even more preferably 95% or more. In addition, in this specification, "substantially" in "substantially the same" means approximately the same, without branching, and in the case of direction, it means a difference within ±3°, and in the case of width, it means ±5 Means a difference within %.

When the number of the convex portions is within the above range, antireflection properties can be easily improved. The number of convex portions is the average value of the number of convex portions at 10 locations (100 μm square area x 10 locations) of the shaped sheet of the present disclosure.

FIG. 3 is a sectional view showing an embodiment of the matte layer 12 constituting the shaped sheet of the present disclosure, in which the matte layer is cut along a plane parallel to its thickness direction (Z direction in the figure). FIG.
The shape of the recess may be, for example, an acute angle as shown in 2a of FIG. 3, a semicircle or a semiellipse as shown in 2b, or a combination thereof. Alternatively, a shape such as 2c in FIG. 3 may be used, in which one convex part has a concave part.
On the other hand, the shape of the convex portion is preferably semicircular or semielliptic, although the width may be wide or narrow as shown in 3a and 3b in FIG.

A matte layer having Rz and RSm within the above ranges can be produced, for example, by the methods (1) and (2) below. In the case of method (2) below, it is important to adjust the blending of the binder resin composition in order to form wrinkles with a fine pitch and high elevation. Furthermore, in the case of the method (2) below, it is important to control the wavelength when curing the binder resin composition.
(1) A surface shape in which Rz and RSm fall within the above ranges is created by simulation. A mold is created by laser engraving the metal surface to reflect the shape created in the simulation. A resin is poured into the mold, and the resin is taken out from the mold to obtain a matte layer.

The amount is 30 parts by mass to 0.70 parts by mass.

When the matte layer contains a matte agent, the matte agent may fall off from the matte layer during the molding process. If the matting agent falls off from the matting layer, the surface shape of the shaping sheet may not be reflected on the object to be shaped, or the object to be shaped may be damaged. For this reason, it is preferable that the matte layer does not substantially contain a matting agent.
As used herein, the term "matting agent" refers to particles having an average particle size with the lower limit being either greater than 100% of the thickness of the matte layer or greater than 30 μm, whichever is smaller.

In order to improve the strength of the shaped sheet, the binder resin preferably contains a cured product of a resin composition containing a curable resin, and more preferably contains a cured product of a resin composition containing an ionizing radiation curable resin. .
Examples of the curable resin include thermosetting resins and ionizing radiation curable resins. Among these, ionizing radiation-curable resins are preferable because they increase the strength of the molded sheet and also easily form wrinkles.

The ionizing radiation-curable resin is a resin having an ionizing radiation-curable functional group, and the ionizing radiation-curable functional group is a group that is crosslinked and cured by irradiation with ionizing radiation, such as a (meth)acryloyl group, a vinyl group, Preferred examples include functional groups having an ethylenic double bond such as allyl groups. In addition, in this specification, a (meth)acryloyl group shows an acryloyl group or a methacryloyl group. Moreover, in this specification, (meth)acrylate refers to acrylate or methacrylate.
In addition, ionizing radiation refers to electromagnetic waves or charged particle beams that have energy quantum that can polymerize and/or crosslink molecules, and ultraviolet rays (UV) or electron beams (EB) are usually used. In addition, electromagnetic waves such as X-rays and γ-rays, and charged particle beams such as α-rays and ion beams are also included.

Ionizing radiation curable resins include electron beam curable resins and ultraviolet ray curable resins. Among these, ultraviolet curable resins that easily form wrinkled shapes are preferred.
Specifically, the ionizing radiation-curable resin can be appropriately selected from polymerizable monomers and polymerizable oligomers that have been conventionally used as ionizing radiation-curable resins.

As the polymerizable monomer, (meth)acrylate monomers having a radically polymerizable unsaturated group in the molecule are preferred, and polyfunctional (meth)acrylate monomers are particularly preferred. Here, "(meth)acrylate" means "acrylate or methacrylate."
Examples of polyfunctional (meth)acrylate monomers include (meth)acrylate monomers having two or more ionizing radiation-curable functional groups in the molecule and at least a (meth)acryloyl group as the functional group.

The number of functional groups of the polyfunctional (meth)acrylate monomer is preferably 2 or more and 8 or less, more preferably 2 or more and 6 or less, even more preferably 2 or more and 4 or less, and even more preferably 2 or more and 3 or less. Further, when the number of functional groups is as described above, it is particularly easy to obtain the above-mentioned surface shape. Polyfunctional (meth)acrylates may be used alone or in combination.

Examples of the polymerizable oligomer include (meth)acrylate oligomers having two or more ionizing radiation-curable functional groups in the molecule and at least a (meth)acryloyl group as the functional group. Examples include urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers, polyester (meth)acrylate oligomers, polyether (meth)acrylate oligomers, polycarbonate (meth)acrylate oligomers, acrylic (meth)acrylate oligomers, and the like.
In addition, other polymerizable oligomers include highly hydrophobic polybutadiene (meth)acrylate oligomers that have (meth)acrylate groups in their side chains, and silicone (meth)acrylate oligomers that have polysiloxane bonds in their main chains. , aminoplast resin (meth)acrylate oligomers modified from aminoplast resins with many reactive groups in small molecules, and molecules of novolac-type epoxy resins, bisphenol-type epoxy resins, aliphatic vinyl ethers, aromatic vinyl ethers, etc. There are oligomers having cationically polymerizable functional groups.

The polymerizable oligomers may be used alone or in combination.
Among the polymerizable oligomers, urethane (meth)acrylate oligomers, epoxy (meth)acrylate oligomers, polyester (meth)acrylate oligomers, polyether (meth)acrylate oligomers, polycarbonate (meth)acrylate oligomers, and acrylic (meth)acrylate oligomers are preferable. , urethane (meth)acrylate oligomer, and polycarbonate (meth)acrylate oligomer are more preferred, and urethane (meth)acrylate oligomer is even more preferred.

The lower limit of the number of functional groups in the polymerizable oligomer is preferably 2 or more, the upper limit is preferably 8 or less, more preferably 6 or less, and even more preferably 4 or less. When the number of functional groups of the polymerizable oligomer is within the above range, it is easy to obtain the above shape, and the strength of the shaped sheet can be easily improved.

When the weight average molecular weight of the polymerizable oligomer is within the above range, the above shape can be easily obtained and the strength of the shaped sheet can be easily improved.

It is difficult to obtain a wrinkled shape using polymerizable oligomers alone. On the other hand, if only the polymerizable monomer is used, excessive wrinkles may be formed. Therefore, the ionizing radiation-curable resin preferably contains a polymerizable monomer and a polymerizable oligomer.
Even when the ionizing radiation-curable resin contains a polymerizable monomer and a polymerizable oligomer, if the proportion of the polymerizable monomer is small, it is difficult to obtain wrinkles with fine pitch and high elevation. Furthermore, even if the ionizing radiation-curable resin contains a polymerizable monomer and a polymerizable oligomer, excessive wrinkles may be formed if the proportion of the polymerizable monomer is too large. Therefore, the mass ratio of the polymerizable monomer to the polymerizable oligomer is preferably 85:15 to 40:60, and preferably 70:20 to 45:55.
More preferably, the ratio is 65:35 to 50:50.

When the ionizing radiation curable resin is an ultraviolet curable resin, the coating liquid for the matte layer preferably contains additives such as a photopolymerization initiator and a photopolymerization accelerator.

《Method for forming a matte layer》
When forming a matte layer by the method (2) above, after applying a coating solution for a matte layer containing an ionizing radiation-curable resin and a wrinkle forming stabilizer onto a base material, a light with a wavelength of 100 nm or more and 380 nm or less is applied. It is preferable to include a step of forming a matte layer by irradiation with
By irradiating ultraviolet light with a short wavelength of 100 nm or more and 380 nm or less, wrinkles can be formed on the surface of the matte layer. Furthermore, by setting the blending ratio of the polymerizable oligomer and the polymerizable monomer within the above range, the pitch and elevation of the wrinkles will be in appropriate ranges, making it easier to obtain a wrinkle shape in which the values of Rz and RSm fall within the above ranges.

Examples of the method for applying the coating liquid for the matte layer include general-purpose methods such as a gravure printing method, a bar coating method, a roll coating method, a reverse roll coating method, and a comma coating method. After applying the coating liquid for a matte layer and before irradiating light of a predetermined wavelength, it is preferable to perform drying as necessary.

The reason why wrinkles are formed on the surface of the matte layer by irradiation with short wavelength ultraviolet rays is presumed to be due to the following mechanism.

When short-wavelength ultraviolet rays are irradiated onto a coated layer coated with a coating solution for a matte layer on a base material, the energy of the ultraviolet rays penetrates only the surface area, and the energy does not reach lower layers, causing the Only the surface portion of the resin composition begins to harden. It is thought that wrinkles are formed when only the surface portion undergoes curing shrinkage. In this way, the formation of wrinkles is thought to occur when only a certain thickness direction from the surface of the coating layer is cured by irradiation with short-wavelength ultraviolet rays. Since curing of the resin is related to the formation of wrinkles, as described above, the mass ratio of the polymerizable monomer to the polymerizable oligomer influences the shape of the wrinkles. Specifically, the higher the proportion of the polymerizable monomer, the higher the wrinkle height tends to be. The pitch of wrinkles is also affected by the altitude of the wrinkles, so just because the proportion of polymerizable monomer is high does not necessarily mean that the pitch becomes short. However, if the proportion of the polymerizable monomer is too small, the pitch of wrinkles will become long.
Further, even if the resin compositions are the same, if the coating liquid for the matte layer does not contain a wrinkle formation stabilizer, wrinkles will not be stably formed. That is, in order to form wrinkles on the entire surface of the matte layer, it is essential that a wrinkle formation stabilizer be included. The wrinkle formation stabilizer is thought to have a function like a nucleus that triggers wrinkle formation.

After the surface portion of the coating layer is cured with light having a wavelength of 100 nm or more and 380 nm or less, it is preferable that another irradiation treatment is performed to also cure the inside of the coating layer.

Examples of light with a wavelength of 100 nm or more and 380 nm or less include rare gases such as Ar, Kr, Xe, and Ne, halides of rare gases such as halogens such as F, Cl, I, and Br, or discharge of mixed gases thereof. Excimer light, which includes light in the ultraviolet wavelength range from an excited state dimer formed by excimer, is preferable.
The wavelength of excimer light and the excimer used as the light source include, for example, light with a wavelength of 126 nm radiated from an Ar ₂ excimer (hereinafter abbreviated as "126 nm (Ar ₂ )"), 146 nm (Kr ₂ ), and 157 nm. (F ₂ ), 172 nm (Xe ₂ ), 193 nm (ArF), 222 nm (KrCl), 247 nm (KrF), 308 nm (XeCl), 351 nm (XeF), and other wavelength light can be preferably employed. As the excimer light, either spontaneous emission light or a laser beam with high coherence (coherence) due to stimulated emission can be used, but it is usually sufficient to use spontaneous emission light. Note that a discharge lamp that emits the light (ultraviolet light) is also called an "excimer lamp."
Excimer light has a single wavelength peak and is characterized by a narrower wavelength half-width than normal ultraviolet light (for example, ultraviolet light emitted from metal halide lamps, mercury lamps, etc.). By using such excimer light, the formation of wrinkles can be stabilized.

In order to stabilize the formation of wrinkles, the wavelength is preferably 120 nm or more, more preferably 140 nm or more, even more preferably 150 nm or more, even more preferably 155 nm or more, and the upper limit is preferably 320 nm or less, more preferably 300 nm or less, It is more preferably 250 nm or less, even more preferably less than 200 nm, and most preferably 172 nm (Xe ₂ ).

The upper limit is not particularly limited, and from the viewpoint of productivity such as reducing the number of lamps required for irradiation with wavelength light and improving production efficiency, it is preferably 1,000 mJ/ ^cm2 or less, more preferably 500 mJ/cm2 or less. cm ² or less, more preferably 300 mJ/cm ² or less. From the same viewpoint, the ultraviolet output density is preferably 0.001 W/cm or more, more preferably 0.01 W/cm or more, even more preferably 0.03 W/cm or more, and preferably 10 W/cm as the upper limit.

Further, the oxygen concentration when irradiating the wavelength light is preferably lower, preferably 1,000 ppm or less, more preferably 750 ppm or less, still more preferably 500 ppm or less, even more preferably 300 ppm or less.

When forming the matte layer, in addition to the above-mentioned irradiation with light having a wavelength of 100 nm or more and 380 nm or less, other treatments that contribute to curing of the resin composition of the coating liquid for the matte layer may be performed.
For example, from the viewpoint of accelerating the progress of curing of the surface portion of the matte layer and the portion deeper than the surface, the matte layer may be pre-irradiated with light having a wavelength exceeding 380 nm, preferably approximately 385 nm or more and 400 nm or less. After precuring the entire resin composition of the coating liquid, it may be irradiated with light having a wavelength of 100 nm or more and 380 nm or less. Alternatively, after irradiation with light having a wavelength of 100 nm or more and 380 nm or less, a post-curing treatment may be performed to further cure the resin composition. The wavelength of pre-curing or post-curing is not limited to ultraviolet rays, but other ionizing radiation such as electron beams can also be used. For example, in the post-curing, electron beams can be preferably used from the viewpoint of improving the surface properties of the matte layer.

The thickness of the matte layer is not particularly limited, but is usually 1 μm or more, preferably 2 μm or more, more preferably 3 μm or more, even more preferably 4 μm or more, and the upper limit is preferably 300 μm or less, more preferably 200 μm. The thickness is more preferably 100 μm or less, more preferably 50 μm or less, more preferably 20 μm or less, and even more preferably 10 μm or less.

Note that the accelerating voltage of the SEM is 3 kV, and the magnification is set according to the thickness. The same applies to the thicknesses of other layers.

For this reason, it is preferable that the matte layer has good releasability. For this reason, it is preferable that the matte layer contains a mold release agent.
