[0004] By providing a glossy layer containing a glossy pigment, a decorative component that expresses a metallic feel can be obtained. On the other hand, there is a demand for low-gloss decorative components, for example, to give a high-end impression.

[0005] This disclosure is made in view of the above circumstances, and its main purpose is to provide a decorative component that achieves both a good metallic feel and a good low gloss.

[0006] In this disclosure, a decorative member is provided, the decorative member having, in the thickness direction, a metal substrate, a low-gloss layer containing porous silica and resin, and a lustrous layer arranged in a pattern and containing a lustrous pigment, and, viewed from the thickness direction, the decorative member has a first region where the lustrous layer and the low-gloss layer exist, and a second region where the lustrous layer does not exist but the low-gloss layer exists, the 60° gloss value of the second region is lower than the 60° gloss value of the first region, the 60° gloss value of the first region is 45 or less, and the flop index of the first region is 4.0 or more.

[0007] Furthermore, this disclosure provides a method for manufacturing a decorative component, comprising: a metal substrate preparation step of preparing the metal substrate; a low-gloss layer formation step of forming the low-gloss layer on one side of the metal substrate; and a glossy layer formation step of forming the glossy layer on the side of the low-gloss layer opposite to the metal substrate.

[0008] This disclosure offers the advantage of providing a decorative component that achieves both a good metallic feel and a good low-gloss finish.

[0009] This is a schematic cross-sectional view illustrating a decorative component in this disclosure. This is a schematic cross-sectional view illustrating a decorative component in this disclosure. This is a schematic cross-sectional view illustrating a decorative component in this disclosure. This is a schematic cross-sectional view illustrating a method for manufacturing a decorative component in this disclosure.

[0010] The embodiments will be described below with reference to the drawings, etc. However, this disclosure can be implemented in many different ways and is not limited to the embodiments described below. In addition, the drawings may schematically represent the width, thickness, and shape of each part compared to the actual form in order to make the explanation clearer, but this is merely an example and should not be interpreted as limiting.

[0011] In this specification, when describing a manner in which one member is placed on another member, the term "above" or "below" includes, unless otherwise specified, both cases: when the other member is placed directly above or directly below the member so as to be in contact with it, and when the other member is placed above or below the member via yet another member. Similarly, in this specification, when describing a manner in which one member is placed on the surface of a member, the term "on the surface" includes, unless otherwise specified, both cases: when the other member is placed directly above or directly below the member so as to be in contact with it, and when the other member is placed above or below the member via yet another member.

[0012] The decorative components and methods for manufacturing the decorative components described herein will be explained in detail below.

[0013] A. Decorative Members Figures 1(a) and 1(b) are schematic cross-sectional views illustrating decorative members in this disclosure. The decorative member 10 shown in Figure 1(a) comprises a metal substrate 1, a low-gloss layer 2, and a glossy layer 3, with the thickness direction D Ｔ In this order, the layers are present. The low-gloss layer 2 contains porous silica and resin. The glossy layer 3 is arranged in a pattern and contains glossy pigments. As shown in Figure 1(b), the thickness direction D ＴFrom this perspective, the decorative member 10 has a first region R where the glossy layer 3 and the low-gloss layer 2 exist. １ In the second region R, the luminous layer 3 is absent, and the low-gloss layer 2 is present. ２ It has the following: Second region R ２ The 60° gross value is the first region R １ It is lower than the 60° gross value. Furthermore, the first region R １ The 60° gloss value and flop index are within a specific range. Also, as shown in Figure 2, the decorative member 10 may further have at least one of the following: a design layer 4, a surface protection layer 5, a base layer 6, and a primer layer 7, in addition to the metal substrate 1, the low-gloss layer 2, and the glossy layer 3.

[0014] According to this disclosure, in the first region where a glossy layer and a low-gloss layer exist, by setting the 60° gloss value and the flop index to a specific range, a decorative component can be made that achieves both a good metallic feel and a good low-gloss feel. Furthermore, by making the 60° gloss value of the second region lower than that of the first region, the entire first and second regions become low-gloss, for example, a design with a high-class feel can be achieved. In addition, when the decorative component is viewed from the glossy layer side, the second region, which has a relatively low 60° gloss value, is located further back than the first region, which has a relatively high 60° gloss value, thus achieving a design with a sense of depth.

[0015] In particular, lowering the 60° gloss value in the first region tends to lower the flop index in the first region. However, in this disclosure, by providing both a glossy layer and a low-gloss layer, it is possible to suppress the decrease in the flop index in the first region even when the 60° gloss value in the first region is lowered. Furthermore, in this disclosure, by using a metal substrate, each layer constituting the decorative member can be made as a baked layer, and a design feel unique to baked layers can be expressed. In addition, by using baked layers, a decorative member with good durability can be obtained. A baked layer is a layer formed by heat curing (baking) a coated composition, and is different from, for example, a layer attached via an adhesive layer.

[0016] 1. First Region and Second Region As shown in FIG. 1(b), the cosmetic member 10 in the present disclosure has a first region R where the bright layer 3 and the low-gloss layer 2 exist, and a second region R where the bright layer 3 does not exist and the low-gloss layer 2 exists, when viewed in the thickness direction D. Ｔ when viewed in the thickness direction D. １ and a second region R where the bright layer 3 does not exist and the low-gloss layer 2 exists, ２ when viewed in the thickness direction D.

[0017] Let the area of the first region be S Ａ and the area of the second region be S Ｂ . The ratio of S Ａ to the sum of S Ｂ and S Ｂ , i.e., S Ｂ / (S Ａ +S Ｂ ), is usually greater than 0 and may be 1% or more, 3% or more, 5% or more, or 10% or more. On the other hand, S Ｂ / (S Ａ +S Ｂ ) is usually less than 100% and may be 99% or less, 95% or less, or 90% or less, depending on the design of the cosmetic member.

[0018] (1) Flop index The flop index of the first region is usually 4.0 or higher, but may be 8.0 or higher, 12 or higher, 14.2 or higher, 15 or higher, 16 or higher, 18 or higher, 20 or higher, 22.6 or higher, or 26.5 or higher. Maintaining a high flop index in the first region yields a good metallic feel. On the other hand, the flop index of the first region is, for example, 55 or lower, but may be 50 or lower, 45 or lower, 35 or lower, or 30 or lower. The flop index of the first region can be controlled, for example, by adjusting the proportion of lustrous pigment in the lustrous layer. Specifically, increasing the proportion of lustrous pigment tends to increase the flop index, and decreasing the proportion of lustrous pigment tends to decrease the flop index, however, increasing the proportion of lustrous pigment too much may conversely decrease the flop index. Furthermore, the flop index of the first region can be adjusted, for example, by the thickness of the glossy layer, the type of resin contained in the glossy layer, and the method of producing the glossy layer (e.g., baking temperature).

[0019] The glossiness of the first region changes significantly in brightness, saturation, and hue depending on the observation position and angle. This characteristic of change is called flop, and the flop index is an index that quantitatively evaluates flop. The flop index is calculated for each L at effect angles of 15°, 45°, and 110°. ＊ (L ＊ １５ , L ＊ ４５ , L ＊ １１０ Using (L), it is calculated from the following formula: Flop index = 2.69 × (L ＊ １５ -L ＊ １１０ ) １．１１ / (L ＊ ４５ ) ０．８５ Details of the measurement method for the flop indicator will be explained in the examples described later.

[0020] (2) 60° Gloss Value The 60° gloss value in the first region is usually 45 or less, but may be 40 or less, 38.4 or less, 35 or less, 31.5 or less, 30 or less, 26.5 or less, 25 or less, 22.6 or less, 20 or less, or 15 or less. By lowering the 60° gloss value in the first region, a good low gloss can be obtained. On the other hand, the 60° gloss value in the first region may be greater than 0.

[0021] The 60° gloss value of the second region is usually lower than that of the first region. This results in a low gloss overall for both the first and second regions, which can create a sophisticated design, for example. The 60° gloss value of the first region is G １ The 60° gross value of the second region is G ２ In that case, the difference between the two (G １ -G ２ For example, the 60° gross value of the second region is 3 or more, may be 5 or more, may be 10 or more, or may be 15 or more. For example, the 60° gross value of the second region is 40 or less, may be 35 or less, may be 30 or less, may be 25 or less, may be 22.5 or less, may be 20 or less, may be 15 or less, may be 14.8 or less, may be 14.5 or less, may be 10 or less, may be 9.2 or less, may be 8 or less, or may be 5 or less. On the other hand, the 60° gross value of the second region may be greater than 0.

[0022] The 60° gloss values ​​in the first and second regions can be controlled, for example, by adjusting the proportion of porous silica in the low-gloss layer. Specifically, increasing the proportion of porous silica tends to decrease the 60° gloss value, while decreasing the proportion of porous silica tends to increase the 60° gloss value.

[0023] The 60° gloss value is measured by placing the decorative material horizontally with the glossy layer facing upwards, and using a gloss meter in accordance with Method 3 of JIS Z 8741:1997. The 60° gloss value is determined as the average value of measurements taken at any 10 locations.

[0024] 2. As shown in Figure 1(a) of the structure of the decorative member, the decorative member 10 comprises at least a metal substrate 1, a low-gloss layer 2, and a glossy layer 3. Furthermore, as shown in Figure 2, the decorative member 10 may further comprise at least one of a design layer 4, a surface protection layer 5, a base layer 6, and a primer layer 7.

[0025] (1) Low gloss layer The low gloss layer in this disclosure contains porous silica and resin. The resin is impregnated into the porous silica, resulting in a low gloss layer.

[0026] The porous silica preferably has an oil absorption capacity of 250 ml / 100 g or more, as specified in JIS K 5101-13-1:2004. The above oil absorption capacity may be 300 ml / 100 g or more, or 350 ml / 100 g or more. Alternatively, the above oil absorption capacity may be 700 ml / 100 g or less.

[0027] The shape of porous silica is usually particulate. The average particle size of porous silica is not particularly limited, but for example, it may be 0.1 μm or more and 7 μm or less, or 1 μm or more and 5 μm or less. In this specification, the average particle size refers to the 50% particle size (d50: median diameter) when the particle size distribution measured by the dynamic light scattering method is expressed as a volume cumulative distribution.

[0028] The specific surface area of ​​porous silica is not particularly limited, but for example, 200 m² ２ It is 1 / g or more, and 220m ２ It may be more than / g, and 260m ２ It may be greater than or equal to / g. The specific surface area is the value measured according to JIS K6217-2 (nitrogen adsorption method).

[0029] The amount of porous silica contained in the low-gloss layer is, for example, 1 part by mass or more and 50 parts by mass or less per 100 parts by mass of the resin component, and may be 1 part by mass or more and 20 parts by mass or 1 part by mass or more and 10 parts by mass or less.

[0030] The low-gloss layer contains a resin. Examples of resins included in the low-gloss layer include polyester resins, acrylic resins, fluororesins, epoxy resins, phenolic resins, urea resins, melamine resins, alkyd resins, amide resins, polyimide resins, silicone resins, urethane resins, urethane-acrylic resins, styrene resins, and cellulose resins. Among these, polyester resins, acrylic resins, and fluororesins are preferred as curable resins. Examples of fluororesins include fluoroethylene-vinyl ether copolymers, fluoroethylene-vinyl ester copolymers, and fluoroethylene-acrylic copolymers.

[0031] The resin contained in the low-gloss layer may be a cured product of a resin composition containing a curable resin and a curing agent. The curable resin is preferably a thermosetting resin. The type of curable resin is not particularly limited as long as the above-mentioned resin is obtained. Examples of the curing agent include isocyanate compounds such as tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPID), and xylylene diisocyanate (XDI). Furthermore, the ratio of the curing agent to 100 parts by mass of the curable resin is not particularly limited, but may be, for example, 30 parts by mass or more and 70 parts by mass or less, or 35 parts by mass or more and 65 parts by mass or less.

[0032] The low-gloss layer may contain a coloring agent. That is, the low-gloss layer may function as a design layer (pattern layer, solid color layer) as described later. The coloring agent will be described later. The low-gloss layer is preferably a baked layer. The thickness of the low-gloss layer is not particularly limited, but for example, it may be 1 μm or more and 10 μm or less, or 3 μm or more and 7 μm or less.

[0033] As shown in Figures 1(a) and 1(b), the low-gloss layer 2 may be arranged in a non-patterned (solid) manner. On the other hand, as shown in Figures 3(a) and 3(b), the low-gloss layer 2 may be arranged in a patterned manner. Even when the decorative member 10 has a patterned low-gloss layer 2, the thickness direction D ＴFrom this perspective, the decorative component 10 has a first region S in which the glossy layer 3 and the low-gloss layer 2 exist. １ In the second region S, the lustrous layer 3 is absent, and the low-gloss layer 2 is present. ２ Furthermore, depending on the pattern of the low-gloss layer 2, the decorative member 10 has a third region S where the glossy layer 3 is present and the low-gloss layer 2 is absent. ３ It may also have a fourth region S where neither the glossy layer 3 nor the low-gloss layer 2 exists, depending on the pattern of the low-gloss layer 2. ４ It may have.

[0034] In other words, the decorative member 10 is in the first region S １ and the second region S ２ It has a third region S ３ and the fourth region S ４ It may further have at least one of the following: The decorative member 10 is in the third region S ３ and the fourth region S ４ By further having at least one of the above, more complex design expressions become possible. Note that the fourth area S ４ The thickness direction D Ｔ From this perspective, it is a region located inside the region identified from the outer edge of the low-gloss layer 2. In other words, the area outside the region identified from the outer edge of the low-gloss layer 2 is the fourth region S. ４ It does not fall under this category. Also, the first region S １ , second region S ２ , third area S ３ and the fourth region S ４ The first region S with respect to the total area １ and the second region S ２ The proportion of the total area is, for example, 5% or more, and may also be 10% or more. On the other hand, the first region S １ , second region S ２ , third area S ３ and the fourth region S ４ The first region S with respect to the total area １ and the second region S ２ The ratio of the total area may be 100% or less than 100%. In the latter case, the first region S １ and the second region S ２The proportion of the total area may be 95% or less, or 90% or less.

[0035] As shown in Figures 1(a) and 1(b), the low-gloss layer 2 and the glossy layer 3 may be in contact. Furthermore, a portion of the resin contained in the glossy layer 3 may be impregnated into the porous silica contained in the low-gloss layer 2. During the heat curing of the glossy layer 3, the resin contained in the glossy layer 3 migrates to the low-gloss layer 2 and impregnates into the porous silica contained in the low-gloss layer 2, thereby reducing the gloss of the low-gloss layer 2. At the same time, as the amount of resin contained in the glossy layer 3 decreases, the ratio of glossy pigment to resin increases, and the value of the flop index increases. In other words, it is possible to achieve both a good metallic feel and a good low-gloss feel simultaneously.

[0036] (2) Luminous Layer The luminous layer in this disclosure is arranged in a pattern and contains a luminous pigment. Examples of luminous pigments include metallic pigments in the form of flakes of aluminum, nickel, cobalt, brass, copper, etc., and pearl pigments in the form of flakes of titanium dioxide-coated mica, basic lead carbonate, aluminum oxide, etc. The luminous pigment may be used alone or in combination of two or more types.

The curable resin is preferably a thermosetting resin. The resin contained in the glossy layer is the same as the resin used in the low-gloss layer described above, so its explanation is omitted here.

[0039] The glossy layer is preferably a baked-on layer. The thickness of the glossy layer is not particularly limited, but for example, it may be 0.5 μm or more and 8 μm or less, or 1 μm or more and 3 μm or less.

The curable resin is preferably a thermosetting resin. The resin contained in the design layer is the same as the resin used in the low-gloss layer described above, so its explanation is omitted here.

[0047] The design layer is preferably a baked-on layer. The thickness of the design layer is not particularly limited, but for example, it may be 1 μm or more and 10 μm or less, or 3 μm or more and 7 μm or less.

[0048] (5) Primer layer The decorative member in this disclosure may have a primer layer between the metal substrate and the low-gloss layer. Providing a primer layer improves the adhesion between the two layers adjacent to the primer layer.

[0049] The primer layer contains a resin. Examples of resins included in the primer layer include urethane resins, acrylic polyol resins, acrylic resins, ester resins, amide resins, butyral resins, styrene resins, urethane-acrylic copolymers, polycarbonate-urethane-acrylic copolymers (urethane-acrylic copolymers derived from polymers (polycarbonate polyols) having carbonate bonds in the polymer main chain and two or more hydroxyl groups in the terminal and side chains), vinyl chloride-vinyl acetate copolymer resins, vinyl chloride-vinyl acetate-acrylic copolymer resins, chlorinated propylene resins, nitrocellulose resins (nitrified cotton), cellulose acetate resins, and fluorine resins.

[0050] The resin contained in the primer layer may be a cured product of a resin composition containing a curable resin and a curing agent. The curable resin is preferably a thermosetting resin.

Examples of the curing agent include isocyanate compounds such as tolylene diisocyanate (TDI), diphenylmethane diisocyanate (MDI), hexamethylene diisocyanate (HDI), isophorone diisocyanate (IPID), and xylylene diisocyanate (XDI).

[0051] The primer layer is preferably a baked layer. The thickness of the primer layer is not particularly limited, but for example, it may be 1 μm or more and 10 μm or less, or 2 μm or more and 5 μm or less.

[0052] (6) Underlayment The decorative member in this disclosure may have an underlayment between the metal substrate and the low-gloss layer. For example, by providing an underlayment, the glossiness of the metal substrate can be obscured or adjusted. The decorative member may also have the above-mentioned primer layer between the metal substrate and the underlayment. The underlayment may be an opaque layer or a transparent (colored transparent or colorless transparent) layer.

[0053] The base layer contains a resin. The resin contained in the base layer may be a cured product of a resin composition containing a curable resin and a curing agent. The curable resin is preferably a thermosetting resin. The resin contained in the base layer is the same as the resin used in the low-gloss layer described above, so no further explanation is given here. The base layer may or may not contain a coloring agent.

[0054] The base layer is preferably a baked layer. The thickness of the base layer is not particularly limited, but for example, it may be 5 μm to 40 μm, or 10 μm to 30 μm.

[0055] (7) Surface protective layer The decorative member in this disclosure may have a surface protective layer on the side opposite to the metal substrate, relative to the low-gloss layer. By providing a surface protective layer, for example, the scratch resistance of the decorative member is improved. Also, as shown in Figure 2, the first region R １ In this configuration, it is preferable that the surface protective layer 5 is positioned between the low-gloss layer 2 and the glossy layer 3.

[0056] The surface protective layer contains a resin. The resin contained in the surface protective layer may be a cured product of a resin composition containing a curable resin and a curing agent. The curable resin is preferably a thermosetting resin. The resin contained in the surface protective layer is the same as the resin used in the low-gloss layer described above, so its explanation is omitted here.

[0057] The surface protective layer may or may not contain fillers. An example of a filler is an organic filler. Examples of organic fillers include resin fillers such as acrylic resins, urethane resins, nylon resins, olefin resins, and urea resins. Among these, acrylic resin fillers (acrylic beads) are preferred because they have good heat resistance and fewer manufacturing constraints. On the other hand, another example of a filler is an inorganic filler. Examples of inorganic fillers include silica, clay, heavy calcium carbonate, light calcium carbonate, precipitated barium sulfate, calcium silicate, and synthetic silicates.

[0058] The average particle size of the filler is, for example, 5 μm or more and 60 μm or less, and may be 10 μm or more and 50 μm or less, or 20 μm or more and 40 μm or less.

[0059] The surface protective layer may contain weather-resistant agents. Adding weather-resistant agents improves the weather resistance of the decorative component. Examples of weather-resistant agents include ultraviolet absorbers and light stabilizers.

Among these, triazine-based UV absorbers are preferred.

[0061] Examples of triazine-based UV absorbers include hydroxyphenyltriazine-based UV absorbers. Examples of hydroxyphenyltriazine-based UV absorbers include 2-(2-hydroxy-4-[1-octyloxycarbonylethoxy]phenyl)-4,6-bis(4-phenylphenyl)-1,3,5-triazine, 2-[4-[(2-hydroxy-3-dodecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, and 2,4-bis[2-hydroxy-4-butoxyphenyl]-6-(2,4-dibutoxyphenyl)-1,3,5-triazine. Examples include azine, 2-[4-[(2-hydroxy-3-tridecyloxypropyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, 2-[4-[(2-hydroxy-3-(2'-ethyl)hexyl)oxy]-2-hydroxyphenyl]-4,6-bis(2,4-dimethylphenyl)-1,3,5-triazine, and 2-(4,6-diphenyl-1,3,5-triazine-2-yl)-5[2-(2-ethylhexanoyloxy)ethoxy]phenol.

[0062] The amount of UV absorber contained in the surface protective layer is, for example, 0.5 parts by mass or more and 10 parts by mass or less per 100 parts by mass of resin component, and may be 0.8 parts by mass or more and 8 parts by mass or 1 part by mass or more and 5 parts by mass. If the amount of UV absorber is too high, bleed-out of the UV absorber may occur, and if the amount of UV absorber is too low, sufficient UV absorption performance may not be obtained.

[0063] On the other hand, examples of light stabilizers include hindered amine light stabilizers.

Next, as shown in Figure 4(f), a surface protection layer 5 is formed on the side of the low-gloss layer 2 opposite to the design layer 4 (surface protection layer formation step). As shown in Figure 4(g), a patterned glossy layer 3 is formed on the side of the surface protection layer 5 opposite to the low-gloss layer 2 (glossy layer formation step). This gives rise to the decorative member 10. In Figure 4, the design layer 4, low-gloss layer 2, surface protection layer 5, and glossy layer 3 are formed in order, but as described in the embodiments below, precursor layers (coating layers) of these layers may be laminated, and then the design layer, low-gloss layer, surface protection layer, and glossy layer may be formed all at once by heating. Thickness direction D Ｔ From this perspective, the decorative component 10 has a first region S in which the glossy layer 3 and the low-gloss layer 2 exist. １ In the second region S, the lustrous layer 3 is absent, and the low-gloss layer 2 is present. ２ It has, and. Furthermore, the second region S ２ The 60° gross value is in the first region S. １ Lower than the 60° gross value, in the first region S ２ The 60° gross value and flop indicator are within a specific range.

[0084] 8. Decorative Components The decorative components obtained through the processes described above are the same as those described in "A. Decorative Components" above.

[0085] This disclosure is not limited to the embodiments described above. The embodiments described above are illustrative, and any configuration that is substantially identical to the technical idea described in the claims of this disclosure and achieves similar effects is included within the technical scope of this disclosure.

[0086] [Example 1] An aluminum plate (A3004PH32, dimensions: 300 mm x 400 mm, thickness: 0.6 mm, chromate treated) was prepared as the metal substrate. Next, as a pretreatment, the prepared aluminum plate was washed with hot water.

[0087] Next, the following primer layer composition was applied to the entire surface of the aluminum plate by gravure offset printing to a dry film thickness of 2 μm. Then, the plate was heated to 224°C to 232°C (substrate temperature) to form the primer layer. (Primer layer composition) Resin (thermosetting polyester resin) Solvent (high-boiling point aromatic naphtha and cyclohexanone) Solids concentration: 74% by mass

[0088] Next, the following undercoat composition was applied to the entire surface of the primer layer using a curtain flow coater to a dry film thickness of 22 μm. Then, it was baked at 177°C (substrate temperature) to form the undercoat. (Undercoat Composition) Thermosetting polyester resin colorant (carbon black, titanium oxide (titanium white), iron oxide (red iron oxide), yellow iron oxide (yellow iron oxide)) Solvent (xylene:cyclohexanone = 1:1, mass ratio) Solids concentration: 35% by mass

[0089] Next, the following low-gloss layer composition was applied to the entire surface of the base layer by gravure offset printing to a dry film thickness of 1 μm to 2 μm. Then, the following surface protection layer composition was applied by gravure offset printing to a dry film thickness of 2 μm. Finally, the following glossy layer composition was applied in a pattern by gravure offset printing to a dry film thickness of 1 μm to 2 μm. After that, the material was baked at 224°C (temperature reached by the base material) to form the low-gloss layer, surface protection layer, and glossy layer, thereby obtaining a decorative component. (Composition for low gloss layer) Resin (thermosetting polyester resin) Porous silica (15% by mass relative to the resin) Solvent (xylene:cyclohexanone = 1:1, by mass ratio) (Composition for surface protective layer) Resin (thermosetting acrylic resin) Silica (7% by mass relative to the resin) Solvent (xylene:cyclohexanone = 1:1, by mass ratio) (Composition for gloss layer) Resin (thermosetting acrylic resin) Glossy pigment (aluminum, 10% by mass relative to the resin) Solvent (xylene:cyclohexanone = 1:1, by mass ratio)

[0090] [Example 2] A decorative member was obtained in the same manner as in Example 1, except that the amount of silica added to the composition for the surface protective layer was changed (silica was not used).

[0091] [Comparative Example 1] First, a primer layer and a base layer were formed on an aluminum plate in the same manner as in Example 1. Next, the following glossy layer composition was applied to the entire surface of the base layer by gravure offset printing to a film thickness of 1 μm to 2 μm after drying. Then, the surface protection layer composition used in Example 2 was applied by gravure offset printing to a film thickness of 2 μm after drying. After that, the plate was baked at 224°C (temperature reached by the base material) to form the glossy layer and the surface protection layer, and a decorative member was obtained. (Composition for glossy layer) Resin (thermosetting polyester resin) Glossy pigment (aluminum, 10% by mass relative to the resin) Solvent (xylene:cyclohexane = 1:1, by mass ratio)

[0092] [Evaluation] (60° gloss value) The 60° gloss value was measured using the cosmetic members obtained in Examples 1 and 2 and Comparative Example 1. Specifically, the cosmetic member was horizontally placed such that the brilliance layer or the surface protection layer was on the upper surface, and a gloss meter (“Micro Tri-Gloss (Cat. No 4563)”, manufactured by BYK Gardner) was used to measure the 60° gloss value (60° specular glossiness) in accordance with Method 3 of JIS Z 8741:1997. The above measurement was performed at 10 arbitrary locations, and the average value was determined as the 60° gloss value of the first region. For Examples 1 and 2, the 60° gloss value of the second region was also determined in the same manner. The results are shown in Table 1.

[0093] (Flop index) The flop index was measured using the cosmetic members obtained in Examples 1 and 2 and Comparative Example 1. Specifically, the cosmetic member was horizontally placed such that the brilliance layer or the surface protection layer was on the upper surface, and a three-dimensional variable-angle spectroscopic color measurement system (manufactured by Murakami Color Technology Laboratory, model number GCMS-4) was used to measure the lightness index L ＊ . The measurement conditions were an incident angle of 45°, a tilt angle of 0°, and an in-plane rotation angle of 0°, the light source was D65, and L ＊ was measured at light receiving angles of 30°, 0°, and -65°. Thereafter, the flop index was calculated from the following formula. The results are shown in Table 1. Flop index = 2.69 × (L ＊ １５ - L ＊ １１０ ) １．１１ / (L ＊ ４５ ) ０．８５ (L ＊ １５ corresponds to L ＊ at a light receiving angle of 30°, L ＊ ４５ corresponds to L ＊ at a light receiving angle of 0°, and L ＊ １１０ corresponds to L ＊ at a light receiving angle of -65°)

[0094]

[0095] As shown in Table 1, in Examples 1 and 2, the 60° gloss value of the first region was low, and the flop index of the first region was high. In other words, in the first region, it was possible to create a design with a good metallic feel while maintaining low gloss. Furthermore, in Examples 1 and 2, the 60° gloss value of the second region was smaller than that of the first region, so it was possible to create a good gloss-matte finish while maintaining low gloss overall. In contrast, in Comparative Example 1, although the flop index was high, the 60° gloss value of the first region was high, and it was not possible to achieve both a good metallic feel and a good low gloss.

[0096] [Example 3] A decorative member was obtained in the same manner as in Example 1, except that the amount of porous silica added to the composition for the low gloss layer was changed (twice that of Example 1), the amount of luminous pigment added to the composition for the gloss layer was changed (15% by mass relative to the resin), and silica was not used in the composition for the surface protective layer.

[0097] [Example 4] A decorative component was obtained in the same manner as in Example 1, except that the amount of porous silica added to the composition for the low gloss layer was changed (twice that of Example 1), the amount of luminous pigment added to the composition for the gloss layer was changed (3% by mass relative to the resin), and silica was not used in the composition for the surface protective layer.

[0098] [Example 5] A decorative component was obtained in the same manner as in Example 1, except that the amount of porous silica added to the composition for the low gloss layer was changed (twice that of Example 1), the amount of luminous pigment added to the composition for the gloss layer was changed (1% by mass relative to the resin), and silica was not used in the composition for the surface protective layer.

[0099] [Comparative Example 2] A decorative member was obtained in the same manner as in Example 1, except that the amount of composition for the glossy layer applied was changed (twice as in Example 1), the amount of glossy pigment added to the composition for the glossy layer was changed (15% by mass relative to the resin), the amount of porous silica added to the composition for the low-gloss layer was changed (twice as in Example 1), and silica was not used in the composition for the surface protective layer.

[0100] [Comparative Example 3] A decorative member was obtained in the same manner as in Example 1, except that the amount of composition for the glossy layer applied was changed (twice that of Example 1), the amount of glossy pigment added to the composition for the glossy layer was changed (3% by mass relative to the resin), the amount of porous silica added to the composition for the low-gloss layer was changed (twice that of Example 1), and silica was not used in the composition for the surface protective layer.

[0101] [Comparative Example 4] A decorative component was obtained in the same manner as in Comparative Example 1, except that the amount of lustrous pigment added to the composition for the lustrous layer was changed (3% by mass relative to the resin), and the amount of porous silica added to the composition for the low-gloss layer was changed (twice that of Example 1).

[0102] [Comparative Example 5] A decorative component was obtained in the same manner as in Comparative Example 1, except that the amount of lustrous pigment added to the composition for the lustrous layer was changed (15% by mass relative to the resin), and the amount of porous silica added to the composition for the low-gloss layer was changed (twice that of Example 1).

[0103]

[0104] As shown in Table 2, in Examples 3 to 5, the 60° gloss value of the first region was low, and the flop index of the first region was high. That is, in the first region, it was possible to create a design with a good metallic feel while maintaining low gloss. Furthermore, in Examples 3 to 5, the 60° gloss value of the second region was smaller than that of the first region, so it was possible to create a good gloss-matte finish while maintaining overall low gloss. In contrast, in Comparative Examples 2 and 3, although the flop index was high, the 60° gloss value of the first region was also high, making it impossible to achieve both a good metallic feel and a good low gloss. Also, in Comparative Examples 4 and 5, the flop index of the first region was high, and the 60° gloss value of the first region was low, but since the second region was not formed, it was not possible to obtain a good gloss-matte finish.

[0105] Furthermore, in Example 3, the gloss value of the first region was higher than in Example 1. This is presumed to be because, although the amount of porous silica added to the low-gloss layer was increased, silica was not used in the surface protective layer, and the proportion of the lustrous pigment was increased. Furthermore, in Example 4, the flop index of the first region was higher than in Example 3. This is because, compared to Example 4, Example 3 had a relatively higher proportion of the lustrous pigment, resulting in L ＊ ４５ The value of increased, and conversely, it is presumed that the flop index of Example 4, in which the proportion of lustrous pigment was relatively low, also increased (it is presumed that if the L value is high at all angles, the change in appearance with respect to angle will be small, and as a result, the value of the flop index will tend to be small). This disclosure suggests that reducing the proportion of lustrous pigment (for example, to 5% by mass or less) is effective in increasing the flop index. A similar trend was confirmed in Example 5.

[0106] On the other hand, in Comparative Example 2, the 60° gloss value in the first region and the 60° gloss value in the second region were higher than in Example 1. This is presumed to be because the thickness of the glossy layer was greater in Comparative Example 2 than in Example 1. A similar trend was observed in Comparative Example 3. Furthermore, in Comparative Example 4, the flop index in the first region was higher than in Comparative Example 1. This is because Comparative Example 1 had a relatively higher proportion of glossy pigment compared to Comparative Example 4, L ＊ ４５ The value increased, and it is presumed that the flop index in Comparative Example 4, which had a relatively low proportion of luminous pigment, also increased. A similar trend was observed in Comparative Example 5.
