  There are a wide variety of design representations in cosmetic materials, but, for example, as described in Patent Document 1 and Patent Document 2, by providing a large number of line-shaped concavo-convex patterns, the intensity, that is, the degree of gloss of light reflected on the surface is improved. There is a technique of giving a specific appearance texture which changes in accordance with a combination of the incident angle of the illumination light and the gaze direction of the observer.

Japanese Examined Patent Publication 7-22989 JP-A-4-125199

By forming a large number of line-shaped concavo-convex patterns as described in Patent Document 1 and Patent Document 2, for example, it is possible to express the feeling of light on the surface of wood (grains).
However, in recent years, there is a demand for further diversification of design expressions, and it is necessary to provide expressions that give new textures to these requests.

  Therefore, an object of the present invention is to provide a cosmetic material provided with a structure capable of realizing a texture different from before. Also, a cosmetic material mold, which is a mold for forming the structure of the cosmetic material, is provided.

  Hereinafter, the present invention will be described.

  One form of the present invention is a decorative material having a concavo-convex pattern formed on the surface, and the concavo-convex pattern is a form in which a plurality of convex linear streaks and concave streaks are arranged alternately. A cosmetic material comprising a plurality of regions in which at least one of the height, width, and extension direction of the linear portions is different and including a plurality of regions in which the heights of the convex linear portions are different.

In this decorative material, when the width of the convex streak portion is W _a and the width of the concave streak portion is W _b and W _a / W _b is the duty ratio, the duty ratio does not depend on the height H of the convex streak portion Can be configured to include a plurality of regions having a constant relationship.

In the above-mentioned decorative material, when the width of the convex streak portion is W _a and the width of the concave streak portion is W _b and W _a / W _b is the duty ratio, the higher the height H of the convex streak portion, the higher the duty ratio It can also be configured to include a plurality of regions having a smaller relationship.

In the above-mentioned decorative material, when the width of the convex streak portion is less than 30 μm, or when the width of the convex streak portion is W _a and the height of the convex streak portion is H, H / W It can also be configured such that _a is greater than one.

  Another aspect of the present invention is a mold for forming a concavo-convex pattern of a cosmetic material having a concavo-convex pattern formed on the surface, wherein a concavo-convex pattern of a shape corresponding to the concavo-convex pattern of the cosmetic material is formed on the surface of the mold The concavo-convex pattern formed on the mold has a form in which a line-like convex streak and a concave streak are alternately arranged, and the depth, width, and extending direction of the concave streak are at least 1 is a mold for a cosmetic material, wherein a plurality of different regions are provided and a plurality of regions having different depths of concave streaks are included.

In this mold for a decorative material, the depth H of the concave streak portion when the width of the concave streak portion in the mold is W _a and the width of the convex streak portion is W _b and W _a / W _b is the duty ratio Alternatively, a plurality of regions having a constant duty ratio may be included.

Further, in the mold for decorative material, when the width of the concave linear portion of the mold is W _a and the width of the convex linear portion is W _b and W _a / W _b is the duty ratio, the depth of the concave linear portion is A plurality of regions having a relationship in which the duty ratio decreases as the depth H becomes deeper may be included.

In the mold for decorative material, when the width of the concave linear portion is less than 30 μm, or the width of the concave linear portion is W _a and the height of the convex linear portion is H, The H / W _a may be configured to be larger than one.

According to the cosmetic material of the present invention, due to the unique structure having the line-like unevenness, the glossiness, which changes according to the combination of the incident angle of the illumination light and the gaze direction of the observer, is different from the conventional one. , Will have a more varied texture. Furthermore, when the unevenness (concave and convex pattern) on the surface of the cosmetic material is touched by hand, the height of the convex streaks differs from area to area, and so a cosmetic material consisting of convex lines having the same height in the entire area of the prior art In comparison, it has a more varied texture in touch.
Moreover, according to the mold for a cosmetic material, such a unique structure can be easily formed.

It is the figure which expanded and represented a part of surface of the makeup material 10. FIG. FIG. 2 is a diagram focusing attention on one unit area 13 in FIG. Fig.3 (a)-FIG.3 (c) are figures showing the cross section of the makeup material 10. As shown in FIG. It is a figure explaining a meshy field. It is a figure explaining the scene which forms an unevenness | corrugation in a type | mold by a laser. FIG. 6A to FIG. 6C are diagrams for explaining another example of the layer configuration of the cosmetic material 10.

  Hereinafter, the present invention will be described based on the embodiments shown in the drawings. However, the present invention is not limited to these embodiments. In the drawings shown below, the sizes and proportions of members may be changed or exaggerated for ease of understanding. In addition, in order to make it easy to view, illustration of unnecessary parts in the description and reference numerals that are repeated may be omitted.

FIG. 1: is the figure which expanded a part of cosmetic material 10 concerning one form, and was planarly viewed from the uneven layer 12 side. FIG. 1 also shows arrows (x, y, z) indicating directions for the sake of convenience. Here, the xy direction is the in-plane direction of the cosmetic material 10, and the z direction is the thickness direction.
As can be seen from FIG. 1, in the decorative material 10, unit areas 13 which are areas of a regular hexagon are two-dimensionally arranged in the xy direction in a two-dimensional view. For easy understanding, one unit area 13 is outlined with a thick line in FIG.
The unit region referred to here is a repeating unit, that is, by repeatedly arranging adjacently in a direction having translational symmetry (direction orthogonal to three pairs of opposite sides) in a plane (xy plane). It means an area that becomes a unit capable of covering a flat surface without gaps.

FIG. 2 shows an enlarged view of one unit area 13 extracted from FIG. As can be seen from FIG. 2, the unit region 13 is further divided into ten regions of a plurality of individual regions 14 to individual regions 23, and the respective uneven patterns are formed on the individual regions 14 to individual regions 23.
In the decorative material 10 of the present embodiment, unit areas 13 as repeating units are arranged, and an individual area 14 to an individual area 23 having respective concavo-convex patterns are formed in the unit area 13. However, in the present invention, there may be no unit region as such a repeating unit, and a plurality of individual regions may be formed on the whole. Further, in the present embodiment, there are two types of regions, and they are referred to as “unit region” and “individual region” for easy understanding, but they can be generically expressed as “regions”.

  Although dotted lines are partially shown in FIGS. 1 and 2, these dotted lines are lines that do not actually exist, but are virtual lines added to make it easier to understand the boundaries of unit areas and individual areas. . As can be seen from FIG. 1, in the present embodiment, the unit area 13 is a regular hexagon, and in the unit area 13, the individual areas 14 to the individual areas 23 are triangles.

The cross-sectional shape with which three separate area | regions 14, 15, 16 are equipped among the separate area | region 14-the separate area | region 23 was represented to Fig.3 (a)-FIG.3 (c). This cross section is a thickness direction (z direction) cross section perpendicular to the direction in which the ridges of the convex linear portions formed in the individual regions extend.
As can be seen from FIGS. 3A to 3C, the decorative material 10 is configured to have a base 11 and a concavo-convex layer 12 laminated on one surface of the base 11. The concavo-convex layer 12 forms the shapes of the unit area 13 and the individual area 14 to the individual area 23.

  The base 11 is a sheet-like member having a function of supporting the uneven layer 12 and imparting strength to the decorative material 10. The base material 11 is not particularly limited as long as it has the same function as a conventionally known cosmetic material. For example, as the material of the substrate, usually, polyolefin resins such as polyethylene, polypropylene, olefin thermoplastic elastomer, ionomer, acrylic resins such as polymethyl methacrylate and polybutyl methacrylate, thermoplastic resins such as polyethylene terephthalate and polybutylene terephthalate Thermoplastic resins such as polyester resin, thermoplastic urethane resin, vinyl chloride resin, ABS resin (acrylonitrile-butadiene-styrene copolymer), styrene resin etc., melamine resin, unsaturated polyester resin, two-component curing urethane resin etc. A curable resin, or an ionizing radiation curable resin or the like which is cured by ionizing radiation (ultraviolet light, electron beam or the like) of a radical polymerization type acrylate type or cationic polymerization type epoxy type is used. In addition, when the material of a base material is resin, you may color with a well-known coloring agent. Other than this, paper, non-woven fabric, metal, wood and the like may be used in the form of a sheet, a plate, a three-dimensional object, etc., appropriately laminated with the above resin material.

  The thickness of the substrate is not particularly limited, but in the case of a sheet-like substrate or a film-like substrate, for example, the thickness is about 20 μm or more and about 1000 μm or less, and in the case of a plate-like substrate, for example, 1 mm or more and 20 mm or less A degree of thing is used.

  The concavo-convex layer 12 is a layer having concavities and convexities laminated on one surface of the base material 11, and the concavities and convexities have a predetermined shape such as the unit area 13 and the individual area 14 to the individual area 23 Configured. In the present embodiment, the concavo-convex layer 12 has the following configuration.

  As described above, in the present embodiment, the concavo-convex layer 12 has unit areas 13 of a regular hexagon in a plan view of the decorative material 10, and a plurality of unit areas 13 are two-dimensionally arrayed in the xy plane It is covered. Then, each unit area 13 is divided into a plurality of individual areas 14 to individual areas 23, and the respective uneven shapes are formed for each individual area. The individual areas 14, 15, 16 will be described below as an example.

As can be seen from FIG. 2 and FIG. 3A, the individual region 14 is formed with a concavo-convex pattern, and the concavo-convex pattern is an array of convex linear streaks 14 a and concave streaks 14 b arranged alternately. It will be done.
The convex linear portion 14a is a rectangle having a height H _14a and a width W _{14a in} the cross section shown in FIG. 3 (a). The convex linear portion 14a has this cross section, and is configured such that ridge lines extend in a direction different from the arrangement direction (for example, a direction orthogonal to the arrangement direction). The length to which the convex linear portion 14 a extends is determined by the contour shape of the individual area 14.
Similarly, the concave streak portion 14b is a rectangle having a depth D _14b and a width W _{14b in} the cross section shown in FIG. 3 (a). The concave streak portion 14b is configured to have this cross section and to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 14a). The length to which the concave linear portion 14 b extends is determined by the contour shape of the individual area 14.
Therefore, the pitch P ₁₄ of the convex linear portion 14 a and the concave linear portion 14 b can be obtained by the sum of W _{14 a} and W _{14 b} .

Here, the size of W _14a , W _14b , H _14a , and D _14b is not particularly limited, but it is preferable to be fine from the viewpoint of forming the pattern of the cosmetic material, and in this embodiment, It is preferable that 1 μm ≦ W _14a ≦ 1000 μm, 1 μm ≦ W _{14 b} ≦ 1000 μm, 3 μm ≦ H _{14 a} ≦ 3000 μm, 3 μm ≦ D _{14 a} ≦ 3000 μm.

Further, it is preferable that H _{14 a} / W _{14 a} (also referred to as an aspect ratio), which is the ratio of height to width in the convex streak portion 14 a, be larger than one. According to this, the texture of the cosmetic material can be made more new. However, when the aspect ratio is too large, the degree of difficulty in mold production increases, and stress is concentrated on the concavo-convex pattern when an external force is applied to the mold and the cosmetic material, and damage tends to occur. Therefore, H _14a / W _14a is usually 5 or less, preferably 3 or less.

In addition, although the cross-sectional shape of the convex filament part 14a of this form is a rectangle, it may be another form, without being limited to this. This includes, for example, a trapezoidal shape, a shape having a semicircular tip, and a shape with an R formed at the protruding corner portion, which can be appropriately changed. Since the concave streaks 14b are formed between two adjacent convex streaks 14a, the cross-sectional shape is determined by the shape of the convex streaks 14a. The same applies to the convex streaks and concave streaks in other individual regions.
Here, for the width of the convex streak portion, the width at the center in the height direction is taken as the width of the convex streak portion. Similarly, for the width of the concave linear portion, the width at the center in the depth direction is the width of the concave linear portion.

  The material which forms the uneven | corrugated layer 12 can use the normal material used for a makeup material suitably. The uneven layer 12 is formed of the same material as the substrate 11 if the substrate is heat-softened to press the mold (embossed plate). Moreover, if the uneven layer 12 is laminated on the base material 11 as a separate layer from the base material 11, the same as the base material 11 prepared separately from the base material 11 from the viewpoint of curing the molten composition after molding. Resin can be used.

The individual area 15 is an individual area adjacent to the individual area 14, and a concavo-convex pattern is formed as can be seen from FIG. 2 and FIG. 3 (b). The uneven pattern is formed by alternately arranging convex linear streaks 15a and concave linear streaks 15b in a line shape.
The convex linear portion 15a is a rectangle having a height H _15a and a width W _{15a in} the cross section shown in FIG. 3 (b). The convex linear portion 15a has this cross section, and the ridge line is in a direction different from the arranging direction (for example, a direction orthogonal to the arranging direction) and a direction different from the extending direction of the convex linear portion 14a of the individual region 14 It is configured to extend to The length by which the convex linear portion 15 a extends is determined by the contour shape of the individual area 15.
The concave streak portion 15b is a rectangle having a depth D _15b and a width W _{15b in} the cross section shown in FIG. 3 (b). The concave streak portion 15b is configured to have this cross section and to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 15a). The length to which the concave linear portion 15 b extends is determined by the contour shape of the individual area 15.
Thus the pitch _{P 15} of the convex linear portions 15a and凹線strip portion 15b can be obtained by the sum of the _{W 15a} and _{W 15b.}

Here, preferable ranges of the height H _15a , the depth D _15b , the width W _15a , and the width W _{15b in} the individual area 15 can be considered in the same manner as the individual area 14. In addition to this, in the individual area 15, in relation to the individual area 14, it is preferable that _H14a > _H15a . Further, in the present embodiment, the individual regions 15 are set to _satisfy D _{14 b} > D _{15 b} , W _{14 a} = W _{15 a} , W _{14 b} <W _{15 b} , and P ₁₄ <P ₁₅ .

The individual area 16 is also an individual area adjacent to the individual area 14, and a concavo-convex pattern is formed as can be seen from FIG. 2 and FIG. 3 (c). The uneven pattern is formed by alternately arranging convex linear streaks 16a and concave linear streaks 16b in the shape of a straight line.
The convex linear portion 16a is a rectangle having a height H _16a and a width W _{16a in} the cross section shown in FIG. 3 (c). The convex linear portion 16a has this cross section, and the ridge line is in a direction different from the arranging direction (for example, a direction orthogonal to the arranging direction) and a direction different from the extending direction of the convex linear portion 14a of the individual region 14 It is configured to extend to The length to which the convex linear portion 16 a extends is determined by the contour shape of the individual area 16.
The concave streak portion 16b is a rectangle having a depth D _16b and a width W _{16b in} the cross section shown in FIG. 3 (c). The concave streak portion 16 b has this cross section and is configured to extend in a direction different from the arrangement direction (for example, a direction perpendicular to the arrangement direction, parallel to the convex streak portion 16 a). The length to which the concave linear portion 16 b extends is determined by the contour shape of the individual area 16.
Accordingly, the pitch P ₁₆ of the convex linear portion 16 a and the concave linear portion 16 _b can be obtained by the sum of W _{16 a} and W _{16 b} .

Here, preferable ranges of the height H _16a , the depth D _16b , the width W _16a , and the width W _{16b in} the individual area 16 can be considered in the same manner as the individual area 14. It is preferably a discrete in region 16 _{H 14a> H 16a} in addition to this. Furthermore, in the present embodiment, the individual regions 16 are set to _satisfy D _{14 b} > D _{16 a} , W _{14 a} <W _{16 a} , W _{14 b} <W _{16 b} , and P ₁₅ = P ₁₆ .

The same applies to the other individual regions 17 to 23. It is preferable that at least one of the height, width, and extending direction of the convex linear portion be different from the adjacent individual region.
By these, the uneven | corrugated layer 12 can express the characteristic texture different from before until now.

Among the above, in the present invention, the area in which the heights of the convex streaks are different between a plurality of areas (area as a generic term of the area existing in the concavo-convex layer regardless of unit areas and individual areas). Shall be included. By including a plurality of regions having different heights in this manner, it is possible to enhance the variety of expression of texture different from the conventional one.
Here, in order to make the heights of the convex streaks different among the regions as described above, the following may be performed. That is, assuming that the width of the convex streak portion is W _a and the width of the concave streak portion is W _b and W _a / W _b is the duty ratio, the duty ratio W _a / W does not depend on the height H of the convex streak portion. It can be configured such that the duty ratio W _a / W _b decreases as W _b is the same or as the height H of the convex linear portion increases. This makes it possible to express the texture different from the conventional one.

  In addition, although the ridge line part of each area | region shown so far is the form in which the ridgeline is extended linearly, a convex filament part is not limited to this, and other curved lines, wave shape, etc. in the direction which ridgeline extends. It can also be in form.

Next, an example of a method of manufacturing the cosmetic material 10 will be described. However, the method of manufacturing the cosmetic 10 is not limited to this.
The manufacturing method described below includes a process of preparing an original image, a process of preparing an under-plate image, a process of preparing a plate, and a process of forming a concavo-convex layer.

In the process of producing a document image, a pattern to be expressed on the concavo-convex layer 12 is obtained and used as a document image. Since the original image is preferably digital data, if it is not digital data, it is converted to digital data by using a photo, a scanner or the like. Also, if the design is designed from the beginning using digital data using CAD or the like, the digital data can be used.
Thus, an original image is obtained as digital data.

  In the step of producing the underprint image, a density-line conversion program generates a line pattern as a binary image on a two-dimensional virtual plane corresponding to the gradation image of the pattern by using a density-line conversion program. Layout, and obtain an underprint image as digital data.

  Here, according to the preset line conditions such as the period of the convex streaks, the line shape of all lines, the direction in which the lines extend, and the variable range of the width of all lines, all lines are displayed as binary images Generate The line segments of the lines generated in this manner correspond to convex streaks in the cosmetic material, and the portions between the line segments and the straight lines correspond to concave streaks in the cosmetic material. In this way, an underprint image having a line pattern is obtained.

In the process of producing the printing plate, an embossed printing plate (molding die for cosmetic material) having a concavo-convex pattern having a plan view shape as shown in FIG. 1 on the surface is produced based on the underprinting image.
The asperity pattern has an aggregate of individual areas defined by covering flat surfaces by connecting adjacent individual areas 14-23, 14-23, 14-23,...
Here, such a concavo-convex pattern, as shown in FIG. 4 corresponding to FIG. 1 (a part of which is represented by a thick line for ease of viewing), consists only of the contour shape of each region and is a linear shape In the area corresponding to each individual area 14 to 23, 14 to 23,..., With respect to the reticulated area 12 ′ that does not have the convex streaks and the concave streaks of It is considered that the portions 14a, 15a, 16a, ... and the concave streak portions 14b, 15b, 16b, ... are alternately arranged.
And the manufacturing process of an uneven | corrugated pattern specifically consists of the following procedures (1)-(5).

[(1) Gradation version image creation process]
The following image creation processes (1) -1 to (1) -3 are performed using the graphic design drawing software "Illustrator" manufactured by Adobe Systems, Inc. and 2540 dpi in 8 bit image gradation (256 gradations) in TIFF format. The image data of the resolution of (net-like area, lines and composite image of both) was created.

(1) -1
First, an image of a net-like region 12 ′ corresponding to the image shown in FIG. 4 from which the line image was removed was created from the planar view image of the concavo-convex pattern of FIG.

(1) -2
, 22a and 22b and 23b, 15a and 15b, and 15a and 15b, and 22a and 15b, respectively. Digital gray-scale image data corresponding to the shapes of 22b, 23a and 23b (hereinafter, also referred to as a line shape) were created according to the following specifications. An example is shown in Table 1.
The gray-scale image corresponds to the image density corresponding to one coordinate of the metal roll surface described later.

  Here, since the density corresponds to the plate depth of the embossed plate through the laser beam engraving process, and the absolute value of the density itself has no meaning, the image density value in the above table is the plate depth (plate depth) It is converted to and displayed. Moreover, the azimuth which is the extension direction of a concave filament part and a convex filament part is the value measured leftward from the x-axis of FIG.1 and FIG.2.

(1) -3
Using the drawing software “Illustrator”, the line shape for each individual area obtained above is embedded in each individual area in the net-like area obtained above, and gray-scale image data corresponding to the concavo-convex pattern of FIG. 1 I got This gradation image data is also referred to as unevenness image data.

[(2) Metal roll preparation process]
In parallel to the above step (1), a metal roll 30 for embossed plate engraving as shown in FIG. 5 was prepared. The metal roll 30 is formed by plating a copper layer on the surface of a hollow iron cylinder having a rotation drive shaft (shaft) 31 at both axial ends. The surface of the metal roll 30 was polished and roughened with a grindstone, and processing was performed to prevent a decrease in engraving efficiency due to specular reflection of the engraving laser light.

[(3) Laser light engraving process]
As schematically shown in FIG. 5, the surface of the metal roll 30 prepared in step (2) is engraved based on the concavo-convex pattern image data prepared in step (1) using a laser beam direct engraving machine. In this way, the uneven shape of the cosmetic material surface as shown in FIG. 1 is formed in the same plan view shape and the reverse asperity (the part corresponding to the convexity of the cosmetic material becomes concave on the embossed plate surface) on the surface. .
Therefore, the shape which the uneven | corrugated pattern in an embossing plate should have is the aspect which the uneven | corrugated relationship of the uneven | corrugated pattern in the above-mentioned decorative material reversed, and can consider it similarly considering the reversed form.

The metal roll 30 is driven via its rotary drive shaft 31 and rotates around the rotary drive shaft 31. The entire surface of the metal roll 30 is scanned with fiber laser light L having an oscillation wavelength of 1024 nm, a laser spot diameter of 10 μm, and an output of 600 W emitted from the laser head 32. At that time, the laser light is switched ON / OFF (switched between irradiation and non-irradiation) according to the density value of the concavo-convex pattern image data created in step (1), and the metal is evaporated by the laser light at the irradiation position. A recess of 10 μm in depth is formed. The scanning of the metal roll surface by the laser light was repeated 10 times. Further, in order to prevent the evaporated metal from becoming powder and remaining or adhering to the surface of the metal roll 30, the engraving liquid T was sprayed from the engraving liquid discharge head 33 onto the laser light irradiated area of the surface of the metal roll 30. Laser light was irradiated in the state.
At that time, for example, at position coordinates of the image density corresponding to the plate depth of 50 μm on the concavo-convex pattern image data, the laser light is irradiated (ON) only for the first five times out of a total of 10 scans. The laser beam is controlled to be non-irradiated (OFF) for batch.
The scanning of the laser light was completed, and the desired asperity shape was formed on the surface of the metal roll 30.

[(4) electric field polishing process]
After cleaning the engraving solution, electrolytic polishing was performed to remove metal residue attached to the surface of the metal roll 30.

[(5) Chrome plating process]
After step (4), a 10 μm thick chromium layer was formed on the surface of the metal roll by plating.

  Thus, it is possible to obtain a plate (a mold for a decorative material, in this embodiment, an embossed plate) having on the surface thereof a concavo-convex shape formed by reversing the concavities and convexities of the concavo-convex pattern formed on the surface of the concavo-convex layer 12.

Next, in the step of forming the concavo-convex layer, the embossed material is obtained by embossing the substrate 11 using the produced plate (embossed plate). Embossing may be performed by any appropriate known method, and is not particularly limited. For example, a typical method of embossing is as follows.
A resin sheet made of a thermoplastic resin such as a polyolefin resin is used as a substrate. This base material is heated and softened, and the embossed plate is pressed against the surface thereof to form an irregular pattern of the embossed plate surface on the surface of the resin sheet. Then, the resin sheet is cooled and solidified to fix the uneven pattern on the resin sheet. Thereafter, the resin sheet on which the concavo-convex pattern is shaped is released from the embossed plate.
Here, various embossing methods will be further described, for example, the following methods (A) to (E).

(A) A resin sheet to be a base material is heated and softened, and an embossed plate is pressed to perform embossing.
(B) Embossing and lamination by thermally fusing a resin sheet (base material) to be a surface sheet by heat pressure when pressing an embossing plate and a resin sheet (second base material) to be a base sheet At the same time, embossing is performed by the double embossing method.
(C) The resin sheet (base material) used as a surface sheet is melt-extruded from a T-die, brought into contact with a cylindrical embossing plate which also serves as a cooling roller, and embossed simultaneously with the film formation of the surface sheet. At this time, the resin sheet (second base material) serving as a base sheet inserted into the back side of the top sheet is heat-sealed to perform doubled embossing simultaneously with film formation.
(D) As disclosed in JP-A-57-87318 and JP-A-7-32476, an uncured liquid of ionizing radiation curable resin is coated on the surface of a cylindrical embossed plate. Furthermore, in a state where a base sheet made of a resin sheet or the like is superposed thereon, ionizing radiation is irradiated to cure the uncured liquid material to form a cured product. At this time, after bonding to the base sheet, the base is released from the embossing plate and made into a base material comprising the base sheet and the cured product on the base sheet, whereby the base material is embossed.
(E) An impregnated paper obtained by impregnating a paper such as titanium paper with an uncured material of a thermosetting resin such as melamine resin is placed on core paper and wood plywood, and heat is applied from these substrates by heat pressing. A curable resin cosmetic material is produced. At that time, by inserting an embossing plate on the surface side of the impregnated paper, when the thermosetting resin is impregnated and cured to make a cosmetic material, the surface is embossed simultaneously with the heat pressing.

  In addition, a thermoplastic resin is typically used as a material of the base material used by the embossing method of (A)-(C), and it is representatively shown as a material of the base material used by the embossing method of (D) Ionizing radiation curable resin is used, and thermosetting resin is typically used as the material of the substrate used in the embossing method of (E).

  The cosmetic 10 can be obtained as described above.

  Next, a cosmetic material as a modification of the cosmetic material 10 described above will be described. The layer configuration is shown in FIGS. 6 (a) to 6 (c). Here, in FIG. 6A to FIG. 6C, the region 14 appears as a part of the uneven layer 12, but the form of the uneven layer 12 is as described above.

  Cosmetics material 10 'of a structure of Fig.6 (a) is a cosmetic material which consists of a single | mono layer. Such a cosmetic material 10 ′ may be embossed, for example, by heating and softening the base material 11 made of a thermoplastic resin sheet and pressing an embossed plate. As a result, a concavo-convex pattern is formed on the surface of the base material 11 by the concavo-convex layer 12 composed of the convex streak part 14 a and the concave streak part 14 b having a desired concavo-convex shape. In this configuration, there is no additional decorative layer, but even when the substrate 11 is transparent, by laminating it on another material, it is possible to make a surface makeup utilizing the pattern of the other material. In addition, the substrate 11 may be colored appropriately with a coloring agent such as brown or gray, and in this case, the substrate itself is a decorative layer.

  Cosmetics material 10 '' of a structure of FIG.6 (b) is the structure which formed the decoration layer 11a in the back side of the base material 11 with respect to the structure of Fig.6 (a). In order to produce the decorative material 10 ′ ′ having such a configuration, for example, a transparent resin sheet is used as the base 11 so that the decorative layer 11 a can be seen through, and the back side of the base 11 is decorated After the layer 11a is formed by printing, the layer may be heated and softened to perform embossing for pressing the surface on which the embossed plate is the front side.

  With respect to the decorative material 10 ′ ′ ′ of the configuration of FIG. 6C, the surface of the decorative layer 11a further includes the base on the side opposite to the side on which the concavo-convex layer 12 is disposed as compared with the configuration of FIG. It is the example which laminated | stacked the other base material 11b used as a sheet | seat. In order to produce the decorative material 10 ′ ′ ′ having such a configuration, the decorative layer 11a is printed on the front surface of the base material 11b made of a colored opaque thermoplastic resin sheet as a base sheet. It is sufficient to laminate this base sheet and the base material 11 made of a transparent thermoplastic resin sheet as a surface sheet by heat fusion using a doubling embossing method and simultaneously emboss a desired uneven pattern on the surface of the base material 11 .

  The application of the decorative material described above is not particularly limited. For example, interior materials of buildings such as walls, floors and ceilings, outer walls of buildings, roofs, gates, fences and other outer coverings, doors, windows Surface materials of frame, door, door frame and other fixtures, edges of skirting, baseboards, handrails, etc., surfaces of household appliances such as TV receivers, surfaces of furniture such as rattan, boxes, etc. It is a surface material of a container, an interior material of a vehicle or the like, an outer covering material, a ship interior material, an outer covering material or the like.
