Description

Technical area

The invention relates to decorative sheets and decorative panels comprising the decorative sheet, and more particularly to a decorative sheet provided with a pattern print and a raised and recessed surface, which is used for interior materials in general, for surface decoration of collapsible furniture and the like, and a decorative panel comprising such a decorative sheet.

background

Decorating films having improved design and improved durability in which a clear layer is laminated on a thermoplastic resin layer having a print thereon, a thermoplastic resin is embossed, or the like has been widely used in practice.

On the other hand, sometimes papers with a print on them are used as decorative foils or decorative papers. For this purpose, a method is known in which a base paper is subjected to printing, impregnated with a thermoplastic resin, and heat and pressure are applied thereto using a press to obtain a decorative plate. According to this method, the thermoplastic resin present on the surface of the decoration plate makes it possible to obtain a decorative plate (or a decoration foil) having a high surface hardness and a high wear resistance.

Patent Literature 1 ( JP H08-132582 A ) discloses an example of such a decorative sheet using a paper as a substrate. The decorative sheet described in Patent Literature 1 is provided with an extrusion layer composed of a thermoplastic resin interposed between two layers of tissue paper (base paper) so that both of the tissue papers are laminated against each other.

Summary

In the decorative sheet described in Patent Literature 1, however, the two sheets of tissue paper are bonded to each other by means of the extrusion coating layer composed of a thermoplastic resin. This bonding increased the tensile strength of these base papers and arguably prevented the paper from tearing, but the design improvement of the decorative sheet was insufficient due to a deeper embossing, thus leaving a need for further design improvement.

Thus, the invention has the object to provide a decorative film with a further improved design and a decorative plate comprising such a decorative film available.

In order to solve the above problem, the decorative sheet of the present invention comprises first and second paper base layers, a thermoplastic resin layer disposed between the first and second paper base layers and bonding the first and second paper base layers, and a pattern layer provided on the first paper base layer is trained. The decorative sheet has a plurality of recessed-defining recessed portions on the side of the surface on which the pattern layer of the decorative sheet is formed, and the maximum depth of the plurality of recessed-defined recessed portions is based on the total thickness of the decorative sheet before stamping 15 % or more.

In this decorative sheet, the maximum depth of the plurality of recessed portions defining the embossing relative to the total thickness of the decorative sheet before embossing is 15% or more. For this reason, much deeper raised and recessed structures are provided on the side of the surface of the decorative sheet, and thus a further design improvement is enabled.

In the above decorative sheet, it is preferable that the maximum depth of the plurality of recessed-defining recessed portions is 45 μm or more. In this case, the design of the decorative film can be pretty good, and also the embossability can be good.

The decorative sheet of the present invention comprises first and second paper base layers, a thermoplastic resin layer disposed between the first and second paper base layers and bonding the first and second paper base layers, and a pattern layer resting on the first A paper base layer is formed, wherein on the side of the surface on which the pattern layer of the decorative sheet is formed, a plurality of embossment defining recessed portions is formed and the maximum depth of the plurality of embossment defining recessed portions is 45 microns or more.

In this decorative sheet, the maximum depth of the plurality of recessed defining recessed portions is 45 μm or more. For this reason, much deeper raised and recessed structures are provided on the side of the surface of the decorative sheet, and thus a further design improvement is enabled.

In the above decorative sheet, it is preferable that the maximum depth of the plurality of recessed-defining recessed portions is 70 μm or more. For this reason, much deeper raised and recessed structures are provided on the side of the surface of the decorative sheet, and thus a further design improvement is enabled.

In the above decorative sheet, it is preferable that the thickness of a paper material used for the first and second paper base layers is 15 μm or more and less than 60 μm. When the thickness of the paper material is 60 μm or more, it is difficult to form a proper embossment in the decorative sheet, and a decorative sheet having a greatly improved design is hardly obtained. Conversely, if the thickness of the paper material is thinner than 15 μm, cracking or the like of the paper material may easily occur at the time of embossing application.

In the above decorative sheet, it is preferable that the thickness of the thermoplastic resin layer is 20 μm or more and 70 μm or less, and that it is thicker than the paper material used for the second paper base layer. When the thermoplastic resin layer has a thickness of 20 μm or more, at the time of emboss deposition, the recessed portions defining the embossment are more surely generated in the decorative sheet, and thus the design can be improved. In addition, such a thickness can prevent the once-embossed structure from returning to the structure before embossing, even if the decorative sheet is laminated or the like.

In the above decorative sheet, it is preferable that the thickness of the paper material used for the first paper base layer positioned on the side of the surface of the decorative sheet is thicker than the thickness of the paper material used for the second paper base layer. In this case, easy printing is enabled (printability improved).

In the above decorative sheet, it is preferable that on the side of a back surface of the decorative sheet which is the opposite side to the surface side in the laminate direction, a plurality of recessed portions are formed. In this case, an adhesive penetrates into the recessed portions when the decorative sheet is adhered to, for example, a substrate, whereby the adhesiveness of the decorative sheet can be improved. Accordingly, the amount of the adhesive to be used can also be reduced. The recessed portions provided on the rear surface side may also reduce wrinkles formed when the decorative sheets are laminated against each other.

In the above decorative sheet, the plurality of recessed parts seen in the laminate direction may be formed at locations other than the locations where the recessed-defining recessed parts are formed.

It should also be understood that the invention is an invention of a decorative panel comprising the decorative sheet formed by one of the above decorative sheets and a substrate, the decorative sheet being laminated on a surface of the substrate. According to this decorative plate, as in the decorative sheet, the effects described above can be achieved.

According to the present invention, a decorative sheet having a further improved design and a decorative sheet comprising such a decorative sheet can be obtained.

Detailed description

Hereinafter, the decorative sheet and the decorative panel of the invention will be described in detail with reference to the drawings. In the description, the same elements or the elements having the same function are designated by the same symbol, and a duplicate description thereof is omitted.

1 is a schematic sectional view showing the sectional structure of the decorative sheet according to the invention. As in 1 is shown, is a decorative foil 10 with a first paper base layer 1 , a second paper base layer 2 a thermoplastic resin layer 3 and a pattern-printed layer (pattern layer) 4 designed. The first and second paper base layers 1 . 2 are by means of the interposed thermoplastic resin layer 3 bound together and attached. The decorative foil 10 has an embossed surface 10a , and on the surface 10a is a variety of recessed parts defining recessed parts 5 educated. Each of the recessed parts defining the coinage 5 For example, in the course of a woodgrain pattern, it is formed in a groove-like shape extending in a longitudinal direction. The decorative foil 10 also has a lot of in-depth parts 6 on the back surface 10b are formed. Each of the recessed parts 6 is like the recessed defining parts 5 for example, formed in a groove-like shape extending in a longitudinal direction. It is preferable that the recessed parts 6 on the side of the back surface 10b Seen in the laminate direction in other places than the locations are formed, where the embossing defining recessed parts 5 on the side of the surface 10a are formed, but they can be seen in the laminate direction also formed in the same places as the points at which the recesses defining recessed parts are formed.

The decorative film comprising such a laminate 10 is heated to a predetermined temperature and passes through an embossing unit, which consists of an embossing roll and a rubber backing roll, whereby on its two surfaces 10a . 10b the sublime and deepened structure is passed on. In the decoration foil 10 Plasticity can be imparted to the laminate when heated. The laminate may be due to the presence of the thermoplastic resin layer 3 also increase the tensile strength. Accordingly, the embossing ability of the laminate is improved.

Examples of the first and second paper base layers 1 . 2 include various paper materials containing 50% or more of cellulosic fibers. For example, it is preferable that the paper material comprising the first and second paper base layers 1 . 2 has a thickness of 15 μm or more and less than 60 μm, and it is more preferable that the thickness is 25 μm or more and 35 μm or less. If the paper material for the first and the second paper base layer 1 . 2 thinner than 15 μm, the strength is not suitable for printing and further processing. Conversely, if the paper material has a thickness of 60 μm or more, the embossing suitability is poor, which is likely to make embossing difficult or difficult to effect deep embossing.

With regard to the thickness of the paper materials comprising the first and second paper base layers 1 . 2 can form the thickness of the paper materials used for the first and the second paper base layer 1 . 2 also be the same in each case. Alternatively, the paper material used for the first paper base layer 1 be thicker than the paper material used for the second base paper layer 2 is used; in other words, the paper material for the second paper base layer 2 thinner than the paper material for the first paper base layer 1 be or vice versa. When the paper material for the second paper base layer 2 Thinner, the paper material may be on the side of the surface 10a into which the embossment is introduced, but are prevented from tearing or the like. When the paper material for the second paper base layer 2 In addition, the total thickness of the entire decorative film can also be made thinner 10 thinner. For this reason, it is preferable that the thickness of the paper material for the second paper base layer 2 thinner than the thickness of the paper material for the first paper base layer 1 is. It should be noted that this is the first paper base layer 1 forming paper material that is thicker than the second paper base layer 2 forming paper material is a slight printing of the first paper base layer 1 (good printability).

The thermoplastic resin layer 3 is between the first and second paper base layers 1 . 2 laminates and binds the first and second paper base layers 1 . 2 together. The thermoplastic resin layer 3 also deforms when the embossment is applied and serves to maintain and fix such a deformed structure. The thickness of the thermoplastic resin layer 3 is not limited, but it is preferable that it is, for example, 20 μm or more and 70 μm or less, and is more preferable to be 35 μm or more and 55 μm or less, and much more preferable in that it is 45 μm or more and 55 μm or less. It is also preferable that the thickness of the thermoplastic resin layer 3 thicker than the paper materials which are the first and second paper base layers 1 . 2 form. It is particularly preferable that the thermoplastic resin layer 3 thicker than the second base paper layer 2 forming paper material or, in other words, the paper material for the second paper base layer 2 thinner than the thermoplastic resin layer 3 is. Such a thermoplastic resin layer 3 is provided by forming a thermoplastic resin layer using, for example, an extruder, and thereon the first and second paper base layers 1 . 2 be laminated.

It is preferable that the thermoplastic resin layer 3 composed of a thermoplastic resin having a melting point of, for example, 100 ° C or more and 200 ° C or less, and that they are composed of, for example, polyvinyl chloride, polyvinylidene fluoride, nylon 12, polyamide, polyvinyl alcohol, polystyrene, styrene-acrylonitrile copolymers , Styrene-butadiene-acrylonitrile copolymers, high density polyethylene, medium density polyethylene, low density polyethylene, polypropylene, ethylene-vinyl acetate copolymers, polyacetal, polymethylmethacrylate, modified acrylic, polycarbonate, polyacetal, nitrocellulose, cellulose propionate, ethylcellulose, cellulose acetate or polyurethane ,

When the melting point of the resin containing the thermoplastic resin layer 3 is in the range of 100 ° C or more and 200 ° C or less, there is no heat deterioration of the paper and the embossing can be practiced without deteriorating the productivity, such as the belt speed. The thermoplastic resin containing the thermoplastic resin layer 3 For example, in consideration of resin cost and melt flowability, it is preferable to use high-density polyethylene, medium-density polyethylene, and low-density polyethylene, for example.

The layer printed with the pattern 4 gives the decoration foil 10 a pattern or the like and is formed by, for example, an ink. Examples of the pattern include a wood grain. As a method of printing, for such a pattern-printed layer 4 To provide a known printing method and a known printing device can be used. The printing method is not particularly limited, but from the viewpoint of productivity, for example, a gravure printing method can be used.

The printing ink containing the patterned layer 4 is not particularly limited and may be any aqueous ink or solution ink. The ink may be properly selected in consideration of the compatibility with a device or the performance required of the decorative sheets and decorative plates. With respect to the colorants contained in the ink, it is generally preferable for the decorative sheet and the decorative plate to use a pigment dye in view of the light resistance.

On the patterned layer 4 For example, a clear resin coating layer (not shown in the figures) may be provided. The intended clear resin coating layer regulates the gloss of the surface 10a the decorative foil 10 and makes it possible to achieve a favorable design. In addition, the proposed coating layer allows the decoration film 10 to improve physical surface properties such as wear resistance. The overcoat layer can also provide a partial difference in gloss, such as in the pore portion of a wood grain. It is thus possible to visually create a raised and recessed effect and combine it with the raised and recessed structure created by embossing to express high quality design.

To provide the coating layer, a known coating apparatus or a gravure printing apparatus may be used. The clear resin forming the coating layer is not particularly limited, but for example, those in which a silica is dispersed in a two-component curing urethane resin to regulate the gloss can be used.

The following is with reference to 2 and 3 a method is described for embossing the laminate comprising the first and second paper base layers 1 . 2 comprising, by means of the thermoplastic resin layer 3 are bound together. It should be noted that the description of the procedure to the Paper materials comprising the first and second paper base layers 1 . 2 form, by means of the thermoplastic resin layer 3 is omitted since conventional methods can be used.

As in 2 (a) is shown, first a laminate 100 made with the second paper base layer 2 , the thermoplastic resin layer 3 , the first paper base layer 1 and the pattern printed layer 4 configured, which are laminated in this order. The total thickness D of the laminate 100 For example, it may be 60 μm to 160 μm, and preferably 80 μm to 120 μm. It should be noted that when forming the laminate 100 the thickness of the paper materials comprising the first and second paper base layers 1 . 2 and so on, because heat and pressure are applied to the laminate.

As in 3 is shown on the obtained laminate 100 then using an embossing device 20 applied an imprint. The embossing device 20 is with a main heating drum 21 , an infrared heater 22 , a bar heating 23 , an embossing roll 24 , a rubber support roller 25 and a take-off roll 26 fitted.

The main heating drum 21 has a cylindrical shape and is rotatable about a central axis line. The laminate 100 that is in the embossing device 20 Introduced initially advances while it is the outer periphery of the main heating drum 21 wraps. The infrared heater 22 There is a heater around the main heating drum 21 wrapped laminate 100 to heat. The infrared heater 22 is close to the main heating drum 21 along a part of the outer periphery of the main heating drum 21 arranged. The laminate 100 moves while the main heating drum 21 turns, downstream and through the infrared heater 22 heated.

The bar heater 23 is a heater to that of the main heating drum 21 from downstream sent laminate 100 continue to heat. The bar heater 23 is arranged along the area in which the laminate 100 from the main heating drum 21 out to the embossing roll 24 and the rubber support roller 25 advances.

The embossing roller 24 and the rubber support roller 25 Form an embossing unit and work together so that they touch the laminate 100 to apply an imprint. The embossing roller 24 and the rubber support roller 25 are on the downstream side of the main heating drum 21 arranged. The embossing roller 24 and the rubber support roller 25 each have a cylindrical shape and are rotatable about the respective central axis line. The embossing roller 24 and the rubber roller 25 touch each other on the outer circumference and bring to the laminate 100 an imprint on when the laminate 100 passes between them. The exact structure of the embossing roller 24 and the rubber support roller 25 will be described later.

The take-off roll 26 is on the downstream side of the embossing roller 24 and the rubber support roller 25 arranged and outputs from the embossing device 20 the laminate 100 (that is the embossed decorative foil 10 ), through the embossing roller 24 and the rubber support roller 25 has gone.

As described above, the embossing device used here has 20 For example, devices for heating the laminate 100 , The heated laminate 100 is then introduced between the embossing unit, which is the embossing roll 24 which has raised and recessed structures provided on its surface, and the rubber support roller 25 includes, and becomes as in 2 B) shaped embossed. If the laminate 100 is heated, the thermoplastic resin layer softens 3 and the surface 100a is easily shaped. Due to the location of the thermoplastic resin layer 3 between the paper materials comprising the first and second paper base layers 1 . 2 In addition, it takes the tensile strength of the heated laminate 100 to, whereby an effect can be achieved that the laminate 100 prevents it from breaking and the like.

To perform embossing, an embossment having a depth of, for example, 15 μm or more is used. This is because an embossment as a design produces a raised and deepened effect and thus effectively appeals to the visual perception when the depth D1 (height difference) of the recessed parts defining the embossment 5 in a finished decorative sheet or decorative panel is 15 microns or more.

In addition, it is preferable, but not limited to, that the rubber supporting roller used in this embodiment has, in particular, a hardness of 50 ° or more and 90 ° or less, and it is more preferable that the rubber supporting roller has a hardness of 50 ° or more and has 70 ° or less. The hardness will be in accordance with for example ISO 7619 measured. In this embodiment, it is preferable to use a rubber support roller having a hardness of 50 °. It should be noted that the embossing design may be poor when using a rubber backing roll with a hardness greater than 95 ° becomes. It should be noted that the hardness of the rubber support roller 25 also in accordance with JIS K 6301 A or JIS K 6253 can be measured, with the hardness thus measured corresponding to the hardness corresponding to ISO 7619 is measured.

The embossing can be done by using the embossing device equipped with the above-described components to obtain the laminate forming the decorative sheet which has been given the raised and recessed surface, thereby forming the decorative sheet 10 can be achieved. The hardness of the rubber support roller used in this embodiment is slightly lower than the hardness of conventional rubber support rollers. When introducing the laminate between the rubber backing roll and the embossing roll by the embossing roll on the side of the surface 100a of the laminate 100 the recessed parts defining recessed parts 5 be formed, for this reason, on the side of the rear surface 100b at the same time the alternating recessed parts 6 formed, which have a predetermined depth. It should be noted that in the above manufacturing process, the recessed portions defining the embossing 5 and the recessed parts 6 on the surface 100a and the back surface 100b on the laminate 100 can be formed substantially simultaneously, but of course also for each surface 100a and the back surface 100b an embossing device may be used to define the recessed portions 5 and the recessed parts 6 provided separately.

Next, the relationship between the total thickness D of the decorative sheet 10 (of the laminate 100 ) before embossing and the depth D1 of the recessed portions defining recessed portions 5 on the side of the surface 10a (also called maximum depth).

The decorative foil 10 According to this embodiment, the embossing method described above starts, and therefore, in the decorative sheet 10 a deeper imprinting than conventional impressions are generated. Thus, the depth D1 is the recessed defining depressed parts 5 in the decoration foil 10 according to this embodiment, based on the total thickness D of the decorative film 10 before embossing 15% or more. It is even more preferable that the depth D1 of the recessed defining portions 5 based on the total thickness D of the decorative film 10 before embossing is more than 10% and 200% or less. The recessed defining parts 5 , which are such strongly recessed parts (groove), make it possible for the decorative film 10 for example, to have a more natural woodgrain design. It should be noted that the depth D1 of the recessed defining depressed parts 5 in particular, for example, 15 μm or more, more preferably 30 μm or more, still more preferably 45 μm or more, and still more preferably 70 μm or more. If the depth D1 of the recessed defining depressed parts 5 gets deeper, the design of the decorative film can 10 can be improved, and it can also enhance the feel and texture of the decorative film 10 can be improved, and also the adhesive strength of the first and the second paper base layer 1 . 2 with the thermoplastic resin layer 3 be improved. The depth D1 of the recessed defining parts 5 is preferably 200 μm or less, and the decorative sheet 10 In this case, excellent moisture resistance can be imparted.

It should be noted that the decoration foil 10 on the side of the back surface 10b that is the side on which the decorative foil 10 is glued to a substrate or the like, with a plurality of groove-like recessed parts 6 is provided. For this reason, the adhesion to a substrate or the like can be easily improved. Also, the recessed parts 6 that are provided on the rear surface side also reduce wrinkles that are formed when the decorative sheets are laminated against each other.

In addition, if the thermoplastic resin is post-heated during embossing, the corresponding peel strength between the thermoplastic resin layer may be increased 3 and the paper material comprising the first paper base layer 1 or the second paper base layer 2 forms, be improved. The peel strength (correlative peel strength) in the case where, for example, a 25 mm-wide decorative sheet is attached to a 3 mm-thick MDF substrate using a double-sided adhesive tape (Sekisui Chemical Co., Ltd., double-sided adhesive tape # 5760) and then using of a tensile tester (Orientec Co., Ltd., RTM-100) having an elastic tension rate of 200 mm / min at 180 °, 1.8 N / 25 mm or more, more preferably 2.3 N / 25 mm or more be.

It should be noted that such a decorative foil 10 For example, it may also be used as a decorative material by being laminated to one of the substrate surfaces using an adhesive. Examples of the substrate used for the decoration material include wood MDF, plywood and chipboard, and inorganic substrates such as gypsum board and metal plate.

Example 1: Using the following ingredients and procedure, a decorative sheet and a decorative sheet using the sheet were prepared.

• (1) A mixed paper (Tentok Paper Co., Ltd., TP23) having a basis weight of 23 g / m ² (thickness 33 μm) was provided as the first paper base, and thereon was coated by using a cellulose nitrate ink (Toyo Ink Co., Ltd., PCNT Ink) and a urethane ink (Toyo Ink Co., Ltd., PCRNT Ink) printed a pattern. Subsequently, a clear surface protective coating was applied to the printed surface at a weight of 7 g / m ² on a dry basis, to which an isocyanate hardener was added to the base resin containing acrylic polyol as a main component to prepare a paper base for the decoration film.
• (2) The paper base on which the pattern was printed as described above was cured at 60 ° C for 48 hours to promote the surface protection layer curing reaction. Thereafter, polyethylene was made high between the side of the paper base which had not been subjected to printing and a mixed paper (Oji Papers Co., Ltd., FIXW23) having a basis weight of 23 g / m ² (thickness 30 μm) as the second paper base Density, which was hot-melted at a heating temperature of 300 ° C, extruded in film form at 2 to 20 g / 10 min, compressed and immediately cooled. This operation resulted in a laminate comprising each of the first and second paper base layers on the front and back surfaces of the polyethylene layer. The thickness of the polyethylene layer was 50 μm, and the total thickness D of the laminate was 101 μm.
• (3) The surface temperature of the pattern-printed surface of the obtained laminate was heated to 130 ° C, which is close to the melting point of polyethylene. The heated laminate was sandwiched between an embossing roller prepared by the corrosion system and having a maximum depth of 150 μm and a rubber support roller having a hardness HS (hardness spring) of 50 ° when measured by a hardness meter JIS K 6301: 1975 to impart the raised and recessed structures to both the surface and the back surface of the laminate for immediate cooling. By doing so, a decorative sheet having the raised and recessed structure was produced. The depth D1 of the embossing defining recessed portions on the surface of the decorative sheet obtained had a height difference of 100 μm or less, and the ratio of the depth D1 with respect to the total thickness D before embossing was 99%, thereby providing a satisfactory design for the decorative sheet was confirmed. The embossing was also easy to apply. The height difference (depth) of the embossing depth D1 was measured by using an integrated surface texture and contour meter (Tokyo Seimitsu Co., Ltd., SURFCOM 120A) at the maximum height (Rmax).
• (4) A one-component ethylene-vinyl acetate emulsion adhesive was applied to a 2.5 mm thick MDF substrate (MDF: medium density fiber) at a coating weight of 55 g / m ² , and using a laminating roller whose surface was at a temperature was heated to 100 ° C, the obtained decorative sheet having the raised and recessed structure was laminated on the MDF substrate. By doing so, a decorative plate having the raised and recessed structure was produced. The embossing defining recessed parts on the decorative plate obtained had a maximum depth of 59 μm, and a decorative plate of satisfactory raised and recessed design could be made.

• (1) (2) Unter Verwendung der gleichen Bestandteile und Vorgehensweise wie im Beispiel 1 wurde mit Ausnahme dessen, dass als der erste Papiergrund ein 52 μm dickes Mischpapier (Tentok Paper Co., Ltd., HP45) verwendet wurde, ein Laminat hergestellt. Die Gesamtdicke D dieses Laminats betrug 117 μm.
• (3) Das so hergestellte Laminat wurde mit der gleichen Vorgehensweise wie im Beispiel 1 geprägt. Die Tiefe D1 der die Prägung definierenden vertieften Teile der erzielten Dekorationsfolie hatte eine Höhendifferenz von maximal 70 μm, und das Verhältnis der Tiefe D1 bezogen auf die Gesamtdicke D vor dem Prägen betrug 60%, wodurch ein zufriedenstellendes Design für die Dekorationsfolie bestätigt wurde.

The following Table 1 collectively shows the above-described Examples 1 to 19 and Comparative Examples 1 to 3. It should be noted that under the item Design in Table 1, "Outstanding", "Good", "Fair" or "Unacceptable" are given, and that they indicate the quality level of the design in this order. "Excellent", "good" and "mediocre" mean passed, while "unacceptable" means failure. Under the heading Embossing in Table 1, "Good" indicates the case that the embossing was easy to apply, while "Fair" indicates the case that the embossing was not easy to apply but feasible. Accordingly, under the point of lamination in Table 1, "good" indicates the case that a decorative plate having a good raised and recessed design could be produced, while "-" indicates the case that the decoration plate was not produced.

As is apparent from the above Table 1, decorative sheets having an embossing depth of 15% or more, more preferably 30% or more, and decorative sheets comprising such decorative sheets can be obtained, thereby confirming the design improvement. It was also confirmed that the decoration foils having a depth D1 of the embossment-defining recessed portions of 45 μm or more, more preferably 70 μm or more, have particularly high-quality designs.
