Description

[Technical field]

[0001] The present invention relates to a decorative film, an exterior part for a transport device, and a transport device. [Background technology]

[0002] Conventionally, methods for increasing the chroma of a coating film have been to reduce the particle size of the pigment contained in the coating film or to add a glittering material of almost the same hue as the pigment (i.e., a similar color) to the coating film. The latter method is disclosed, for example, in Patent Document 1.

[0003] Patent Document 1 relates to a method for forming a red-based multi-layer coating film on a substrate on which an electrodeposition coating film and an intermediate coating film have been formed. The multi-layer coating film is formed by laminating a first color coating film, a second color coating film, and a clear coating film on the substrate. The first color coating film contains a quinacridone pigment as an organic red pigment, and a red or yellowish red iron oxide-coated aluminum pigment as a luster pigment.

[0004] [Patent Document 1] JP 2016-193385 A Summary of the Invention [Problem to be solved by the invention]

[0005] However, when a pigment with a smaller particle size is used, the amount of pigment added must be increased to sufficiently increase the hiding power (i.e. to prevent the base from showing through), which increases the material cost. Also, when a lustrous material is used, in the case of aluminum powder or pearl (mica) powder, which are common lustrous materials, a gray color appears, so although the saturation is increased, a sense of turbidity appears, making it difficult to increase only the saturation.

[0006] The embodiment of the present invention has been made in consideration of the above-mentioned problems, and an object of the present invention is to suitably improve the apparent saturation of a decorative film. [Means for solving the problem]

[0007] This specification discloses a decorative film, an exterior part for a transport device, and a transport device as described in the following items.

[0008] [Item 1] a base layer including at least one pigment that defines a base color; At least one transparent layer provided on the opposite side of the base layer from the object to be decorated; having A transparent layer of the at least one transparent layer contains a glittering material, A decorative film, wherein a difference between a hue angle of the base color and a hue angle of the color of the lustrous material is 60° or more and 142° or less.

[0009] The decorative film according to the embodiment of the present invention has a base layer containing a pigment that defines a base color, and at least one transparent layer provided on the opposite side of the base layer from the object to be decorated, and one of the at least one transparent layer contains a lustrous material. In the decorative film according to the embodiment of the present invention, the difference between the hue angle of the base color and the hue angle of the color of the lustrous material is 60° or more and 142° or less, so that the saturation of the film as a whole as perceived by humans (i.e., apparent saturation) is improved.

[0010] [Item 2] 2. The decorative film according to item 1, wherein the average particle size of the luster material is 50 μm or less.

[0011] The average particle size of the lustrous material is preferably 50 μm or less. If the average particle size of the lustrous material exceeds 50 μm, the lustrous material may be visually recognized as a spotted pattern, which may impair the appearance.

[0012] [Item 3] 3. The decorative film according to item 1 or 2, wherein the content of the luster material in the certain transparent layer is 0.05 PHR or more and 3.0 PHR or less.

[0013] From the viewpoint of enhancing the effect of improving saturation, the content of the luster material is preferably 0.05 PHR or more. Also, from the viewpoint of suppressing the pattern from being visible and the hue of the entire film from being significantly shifted from the base color, the content of the luster material is preferably 3.0 PHR or less.

[0014] [Item 4] 3. The decorative film according to item 1 or 2, wherein the content of the luster material in the certain transparent layer is 0.3 PHR or more and 1.0 PHR or less.

[0015] From the viewpoint of enhancing the effect of improving saturation, the content of the luster material is more preferably 0.3 PHR or more. Also, from the viewpoint of suppressing the pattern from being visible and the hue of the entire film from being significantly shifted from the base color, the content of the luster material is more preferably 1.0 PHR or less.

[0016] [Item 5] 5. The decorative film according to any one of items 1 to 4, wherein the at least one transparent layer is two transparent layers.

[0017] The decorative film according to the embodiment of the present invention is not limited to a two-layer structure, and may have a laminated structure of three or more layers. That is, the transparent layer may be one layer, or may be two or more layers. When the transparent layer is two layers, the transparent layer containing the luster material may be located between the transparent layer not containing the luster material and the base layer, or the transparent layer not containing the luster material may be located between the transparent layer containing the luster material and the base layer.

[0018] [Item 6] Item 6. The decorative film according to item 5, wherein, of the two transparent layers, the transparent layer containing the luster material is located between the transparent layer not containing the luster material and the base layer.

[0019] When a transparent layer containing a lustrous material is positioned between a transparent layer not containing a lustrous material and a base layer, the upper transparent layer does not contain a lustrous material, so that the smoothness and leveling properties of the upper transparent layer are improved, which is advantageous in terms of increasing the gloss.

[0020] [Item 7] Item 6. The decorative film according to item 5, wherein, of the two transparent layers, the transparent layer not containing the luster material is located between the transparent layer containing the luster material and the base layer.

[0021] When a transparent layer that does not contain a lustrous material is positioned between a transparent layer that contains a lustrous material and a base layer, the amount of light that reaches the lustrous material and is reflected by the lustrous material increases because the upper transparent layer contains the lustrous material, which is advantageous in that it can enhance the effect of improving saturation and reduce the amount of lustrous material contained.

[0022] [Item 8] 8. The decorative film according to any one of items 1 to 7, wherein the visible light transmittance of each of the at least one transparent layer is 10% or more.

[0023] The transparent layer has a visible light transmittance of, for example, 10% or more.

[0024] [Item 9] A substrate; A decorative film according to any one of items 1 to 8 provided on a surface of the base material; An exterior part for a transportation device comprising:

[0025] The decorative film according to the embodiment of the present invention is suitably used for decorating exterior parts for transport equipment.

[0026] [Item 10] A transportation device comprising the exterior part for transportation device according to item 9. Effect of the Invention

[0029] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Note that the embodiments of the present invention are not limited to the following examples.

[0030] A decorative film 100 according to an embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a cross-sectional view showing the decorative film 100 in schematic form.

[0031] As shown in FIG. 1, the decorative film 100 is formed on the surface of an object 1 to be decorated. The object 1 to be decorated may be various products, for example, a base material of an exterior part for a transport machine as described later. The decorative film 100 has a base layer 10 and a transparent layer 20. In this embodiment, the case where the decorative film 100 is formed by painting, that is, the case where the decorative film 100 is a coating film will be described. The decorative film 100 may be formed by printing. That is, the decorative film 100 may be a printed film.

[0032] The base layer 10 includes a pigment 11 that defines a base color. The pigment 11 is dispersed in a resin 12. The base color is a color that is the base tone of the color of the decorative film 100. The base color may be defined by one type of pigment 11, or may be defined by two or more types of pigments 11 that are different from each other in color. In other words, the base layer 10 includes at least one type of pigment 11.

[0033] The transparent layer 20 is provided on the opposite side of the base layer 10 to the object to be decorated 1. The transparent layer 20 contains a lustrous material 21. The lustrous material 21 is dispersed in a resin 22. The transparent layer 20 is transparent as a whole and transmits visible light (wavelength range: 360 nm to 830 nm). Therefore, the color of the base layer 10 can be seen through the transparent layer 20. The visible light transmittance of the transparent layer 20 is, for example, 10% or more, and preferably 25% or more. There is no particular upper limit to the visible light transmittance of the transparent layer 20, but it is typically 80% or less. The visible light transmittance can be measured by a spectrophotometer or a visible light transmittance / reflectance meter.

[0034] When the decorative film 100 is formed by baking, the base layer 10 and the transparent layer 20 can be formed by applying a coating composition (called "coating") and baking and drying the applied coating composition (called "baking"). The baking and drying of the coating composition for forming the base layer 10 (hereinafter sometimes referred to as "first coating composition") and the baking and drying of the coating composition for forming the transparent layer 20 (hereinafter sometimes referred to as "second coating composition") may be performed simultaneously (i.e., all at once).

[0035] The first coating composition includes a pigment 11 and a vehicle. As the pigment 11, various known pigments can be used. The pigment 11 may be an inorganic pigment or an organic pigment. The vehicle includes a base agent (base resin), a curing agent, and a solvent. As the base agent, various resin materials for forming a coating film can be used, specifically, alkyd resin, polyester, acrylic resin, epoxy resin, etc. can be used. In addition, as the curing agent, amino resin, polyisocyanate, etc. can be used. As the solvent, an organic solvent and / or water can be used.

[0036] The second coating composition includes a glittering material 21 and a vehicle. As the glittering material (sometimes called "glitter pigment") 21, various known glittering materials can be used. The glittering material 21 has, for example, a substrate of a predetermined shape and a coating layer covering the surface of the substrate. The substrate is formed from glass, aluminum, iron oxide, mica, etc. The substrate can be in various shapes such as a flake shape, a sphere shape, an ellipsoid shape, a square prism shape (not limited to a regular square prism shape, of course). The coating layer is formed from a metal, a metal oxide (e.g., iron oxide, titanium oxide), etc. The vehicle of the second coating composition includes a base material, a curing agent, and a solvent, similar to the vehicle of the first coating composition. Specifically, the base material, the curing agent, and the solvent can be those exemplified for the vehicle of the first coating composition.

[0037] The first and second coating compositions may further include additives to improve the properties of the coating film.

[0038] In the decorative film 100 according to the embodiment of the present invention, the hue of the base color is different from the hue of the glittering material 21. Specifically, the hue angle h 1 and the hue angle h of the color of the glittering material 21 2 The difference Δh between the L and the L is 60° or more and 142° or less (preferably 66° or more and 132° or less). * a * b * A chromaticity diagram of the color space. * a * b * In color space, lightness is L * , chromaticity is a * , b * The hue angle h is an angle in Fig. 2, with the red direction being 0° and the counterclockwise direction being positive (i.e. the yellow, green and blue directions are 90°, 180° and 270°, respectively).

[0039] Note that the above difference Δh does not necessarily depend on the hue angle h 1 and the hue angle h of the 21st color of the glittering material 2 It is not a simple arithmetic difference between h and h, but a value in the range of 0° to 180°. 1 and 2 Absolute value of the difference between |h 1 -h 2 If | is less than 180°, Δh = |h 1 -h 2 |, and h 1 and 2 Absolute value of the difference between |h 1 -h 2 If | is greater than 180°, Δh=360°-|h 1 -h 2 For example, in the case of colors CL1 (h=160°) and CL2 (h=80°) in FIG. 2, the difference in hue angle Δh between them is 80°. In contrast, in the case of colors CL3 (h=280°) and CL4 (h=25°) in FIG. 2, the difference in hue angle Δh between them is 105°.

[0040] In this way, in the decorative film 100 according to the embodiment of the present invention, the hue angle h of the base color is set to approximately the same hue, which is completely different from the conventional technical idea of ​​making the base color and the color of the lustrous material approximately the same hue. 1 and the hue angle h of the 21st color of the glittering material 2 The difference Δh between the angles is 60° or more and 142° or less, and as a result, as will be explained later together with verification results, the saturation perceived by humans (i.e., apparent saturation) of the entire decorative film 100 is improved. The mechanism by which such an effect is obtained is presumed to be as follows.

[0041] There is a known perceptual phenomenon called color afterimages. For example, if you look at a piece of red paper for a few minutes and then look at a piece of white paper, you will see a green afterimage. Also, after looking at green paper you will see a red afterimage, after looking at yellow paper you will see a blue afterimage, and after looking at blue paper you will see a yellow afterimage. In this way, if you continue to look at a certain color and then move your gaze, an afterimage of that color's complementary color will appear. Color afterimages can be explained using the same concept as so-called light adaptation and dark adaptation. In other words, it can be said that the visual system that has been adapted to a certain color by continuing to look at it will begin to strongly perceive the complementary color of that color.

[0042] In the decorative film 100 according to the embodiment of the present invention, the transparent layer 20 containing the lustrous material 21 having a hue different from that of the base color is provided between the base layer 10 and the viewer, which is thought to make the viewer perceive the base color more strongly, thereby improving the apparent saturation. In simple terms, it would seem that the greatest effect would be achieved if the lustrous material 21 were the complementary color of the base color (i.e., Δh is about 180°), but according to the inventor's investigation, this is not the case, and it is also thought that the lustrous material 21 is the complementary color of the base color (i.e., Δh is about 180°). 1 and the hue angle h of the 21st color of the glittering material 2 It has been found that the difference Δh between the above values ​​is preferably 60° or more and 142° or less.

[0043] Figure 3 shows the relationship between the hue difference in the PCCS (Japan Color Research Color System) hue wheel, starting from the yellow hue. A hue difference of 1 corresponds to 15°, and within the range of each numbered circle (within the 15° range) the same hue is present. 1 and the hue angle h of the 21st color of the glittering material 2 When the difference Δh between the base color and the color of the luster material 21 is 60° or more and 142° or less, it can be said that the hue of the luster material 21 corresponds to a mid-difference hue or a contrast hue with respect to the hue of the base color, as compared to the hue of the PCCS hue circle. The reason why the effect of improving saturation is difficult to obtain when the hue of the luster material 21 is an adjacent hue or a similar hue is considered to be because the difference in hue is small, and therefore the visual system is unlikely to produce a response that strongly perceives the base color. In addition, as will be described later with reference to the verification results, the effect of improving saturation is also difficult to obtain when the hue of the luster material 21 is a complementary hue or an adjacent complementary hue. The reason for this is not necessarily clear, but one of the reasons is thought to be that when the difference in hue is too large, a completely opposite signal is transmitted to the brain as a signal that causes a perceptual response, causing a certain kind of confusion.

[0044] As can be seen from FIG. 3, the intermediate difference hue and contrast hue exist on both the clockwise and counterclockwise sides of the starting hue. The hue of the color of the glittering material 21 may be set to either the intermediate difference hue and contrast hue on the clockwise side or the intermediate difference hue and contrast hue on the counterclockwise side of the base color hue. In addition, the glittering material 21 of a hue corresponding to the intermediate difference hue or contrast hue on the clockwise side and the glittering material 21 of a hue corresponding to the intermediate difference hue or contrast hue on the counterclockwise side may be mixed.

[0045] From the viewpoint of the appearance of the decorative film 100, the average particle size of the luminous material 21 is preferably 50 μm or less. If the average particle size of the luminous material 21 exceeds 50 μm, the luminous material 21 may be visually recognized as a spotted pattern, which may impair the appearance. In this specification, the average particle size of the luminous material 21 means the median diameter measured by a laser diffraction / scattering method. There is no particular lower limit to the average particle size of the luminous material 21, but the average particle size of the luminous material 21 is, for example, 15 μm or more.

[0046] From the viewpoint of enhancing the effect of improving saturation, the content of the luster material in the transparent layer 20 is preferably 0.05 PHR or more, and more preferably 0.3 PHR or more. Also, from the viewpoint of suppressing the pattern from being visible and the hue of the entire film from significantly deviating from the base color, the content of the luster material 21 is preferably 3.0 PHR or less, and more preferably 1.0 PHR or less.

[0047] Base color lightness (L * If the value of the base color is too high or too low, it may be difficult to obtain the effect of improving the saturation. The lightness of the base color is preferably, for example, 25 or more and 75 or less.

[0048] Here, the results of verifying the effect of improving saturation according to an embodiment of the present invention will be described. The verification was performed by producing various samples and subjectively evaluating them by visual inspection. The subjective evaluation was performed by having six people visually inspect a number of samples, including samples containing a lustrous material in the transparent layer and samples not containing a lustrous material in the transparent layer, for several base colors, and voting for the sample with the highest saturation (perceived as beautiful). The lustrous material used was glass flakes, the substrate, whose surface was covered with a coating layer.

[0049] [Base color: Blue] Tables 1 and 2 and Figure 4 show the results of the verification for samples with a blue base color. Sample 1A, which does not contain any lustrous material, and Sample 1B, which contains red lustrous material, were prepared. For Sample 1B, two samples with different amounts of lustrous material were prepared (these samples are numbered "1B-1" and "1B-2"). The hue angle of the base color h 1 is the color of sample 1A without the luminescent material measured by a spectrophotometer (Konica Minolta CM-700d) * , b * The hue angle h of the color of the glittering material is calculated from 2 is the value obtained by forming a coating film containing a sufficient amount of luster material and measuring the color of the coating film with a spectrophotometer. * , b *The hue angle h was calculated in the same way for the samples described below. 1 and h 2 Figure 4 shows the chromaticity (a * , b * ) is plotted in the graph.

[0050] [Table 1]

[0051] [Table 2]

[0052] As can be seen from Table 1 and Figure 4, in this example, the hue angle of the base color, h 1 and the hue angle h of the glitter color 2 The difference Δh between the base color and sample 1A was 132°, and the number of votes for sample 1B with the lustrous material was greater than the number of votes for sample 1A without the lustrous material. Also, as can be seen from Table 2, although sample 1B contains a lustrous material with a different hue from the base color, the color difference ΔE * This means that even though there was little difference in the color measurement values ​​between Sample 1A and Sample 1B, Sample 1B seemed to have better saturation than Sample 1A.

[0053] [Base color: Light blue] Tables 3, 4 and Fig. 5 show the results of the verification for samples with a light blue base color. Sample 2A, which does not contain any lustrous material, and Sample 2B, which contains red lustrous material, were prepared. For Sample 2B, two samples ("2B-1" and "2B-2") with different amounts of lustrous material were prepared.

[0055] [Table 4]

[0056] As can be seen from Table 3 and Figure 5, in this example, the hue angle of the base color, h 1 and the hue angle h of the glitter color 2 The difference Δh between sample 2B and sample 2A was 117°, and the number of votes for sample 2B with the lustrous material was greater than the number of votes for sample 2A without the lustrous material. Also, as can be seen from Table 4, the color difference ΔE * was small.

Sample 3A, which does not contain any lustrous material, and Sample 3B, which contains red lustrous material, were prepared. For Sample 3B, two samples ("3B-1" and "3B-2") with different amounts of lustrous material were prepared.

[0060] As can be seen from Table 5 and Figure 6, in this example, the hue angle of the base color, h 1 and the hue angle h of the glitter color 2 The difference Δh between the sample 3B and sample 3A was 66°, and the number of votes for sample 3B with the lustrous material was greater than the number of votes for sample 3A without the lustrous material. Also, as can be seen from Table 6, the color difference ΔE between sample 3B and sample 3A * was small.

[0061] [Base color: dark blue] Tables 7, 8 and Fig. 7 show the results of the experiment for samples with a dark blue base color. Sample 4A, which does not contain any lustrous material, and Sample 4B, which contains red lustrous material, were prepared. For Sample 4B, two samples ("4B-1" and "4B-2") with different amounts of lustrous material were prepared.

[0062] [Table 7]

[0063] [Table 8]

[0064] As can be seen from Table 7 and Figure 7, in this example, the hue angle of the base color, h 1 and the hue angle h of the glitter color 2 The difference Δh between sample 4B and sample 4A was 66°, and the number of votes for sample 4B with the lustrous material was greater than the number of votes for sample 4A without the lustrous material. Also, as can be seen from Table 8, the color difference ΔE between sample 4B and sample 4A * was small.

[0066] [Table 9]

[0067] [Table 10]

[0068] As can be seen from Table 9 and Figure 8, in this example, the hue angle of the base color, h 1 and the hue angle h of the glitter color 2The difference Δh between sample 5B and sample 5A was 152°, and the number of votes for sample 5B with the luminous material was less than the number of votes for sample 5A without the luminous material. As can be seen from Table 8, the color difference ΔE between sample 5B and sample 5A * was small.

[0069] [Base color: Yellow] Tables 11, 12 and Fig. 9 show the results of the verification of samples with a yellow base color. Sample 6A, which does not contain any luster material, Sample 6B, which contains blue luster material, and Sample 6C, which contains green luster material, were prepared. For each of Samples 6B and 6C, two samples with different luster material contents ("6B-1", "6B-2", "6C-1", and "6C-2") were prepared.

[0070] [Table 11]

[0071] [Table 12]

[0072] As can be seen from Table 11 and Figure 9, in sample 6B containing blue glitter, the hue angle h 1 and the hue angle h of the glitter color 2 The difference Δh between the base color and the sample 6C containing green glitter is 174°, whereas the difference Δh between the base color and the sample 6C containing green glitter is 174°. 1 and the hue angle h of the glitter color 2 The difference Δh between the two is 86°. The number of votes for sample 6C, which contains green luster material, was greater than the number of votes for sample 6A, which does not contain luster material, while the number of votes for sample 6B, which contains blue luster material, was less than the number of votes for sample 6A, which does not contain luster material. Also, as can be seen from Table 12, the color difference ΔE * was small.

[0073] [Base color: Green] Tables 13, 14 and Fig. 10 show the results of the verification of samples with a green base color. Sample 7A, which does not contain any luster material, Sample 7B, which contains red luster material, and Sample 7C, which contains blue luster material, were prepared. For Sample 7C, two samples ("7C-1" and "7C-2") with different amounts of luster material were prepared.

[0074] [Table 13]

[0075] [Table 14]

[0076] As can be seen from Table 13 and Figure 10, in sample 7B containing red glitter, the hue angle h 1 and the hue angle h of the glitter color 2 The difference Δh between the base color and the sample 7C, which contains blue luster material, is 158°, while the difference Δh between the base color and the sample 7C, which contains blue luster material, is 158°. 1 and the hue angle h of the glitter color 2 The difference Δh between the two is 114°. The number of votes for sample 7C, which contains blue luster material, was greater than the number of votes for sample 7A, which does not contain luster material, while the number of votes for sample 7B, which contains red luster material, was the same as the number of votes for sample 7A, which does not contain luster material. Also, as can be seen from Table 14, the color difference ΔE * was small.

[0077] As can be seen from the above test results, the hue angle of the base color h 1 and the hue angle h of the 21st color of the glittering material 2 When the difference Δh is 60° or more and 142° or less, the saturation sensed by humans (i.e., apparent saturation) of the entire decorative film 100 is improved. The lower limit of Δh is preferably 66° or more. The upper limit of Δh is preferably 132° or less.

[0078] FIG. 11 shows another example of the configuration of the transparent layer 20. In the example shown in FIG. 11, the transparent layer 20 includes a further luster material 23 having a different color from the luster material 21. Hereinafter, the former luster material 21 will be referred to as the "first luster material" and the latter luster material 23 will be referred to as the "second luster material." The hue angle h of the base color 1 and the hue angle h of the color of the second glittering material 23 3 The difference Δh' between the hue angle of the base color and the hue angle of the second glittering material 23 is less than 60°. In other words, the hue of the second glittering material 23 can be the same hue, an adjacent hue, or a similar hue to the base color. Even when the configuration shown in FIG. 11 is adopted, 1 and the hue angle h of the color of the first glittering material 21 2 The same effect can be obtained when the difference Δh between the above angles is 60° or more and 142° or less. The content of the second glittering material 23 in the transparent layer 20 is, for example, 0.1 PHR or more and 30 PHR or less.

[0079] In the above description, the decorative film 100 has a two-layer structure, but the decorative film according to the embodiment of the present invention is not limited to a two-layer structure and may have a laminated structure of three or more layers. Specifically, the transparent layer 20 may be one layer or two or more layers. When the transparent layer 20 has two or more layers, it is sufficient that one of the two or more transparent layers 20 contains the lustrous material 21. In addition, the visible light transmittance of each transparent layer 20 is, for example, 10% or more.

[0080] 12A and 12B show decorative films 100A and 100B having two transparent layers 20. As shown in Fig. 12A and 12B, the decorative films 100A and 100B have a first transparent layer 20A and a second transparent layer 20B provided on the opposite side of the base layer 10 with respect to the first transparent layer 20A. That is, the first transparent layer 20A and the second transparent layer 20B are laminated in this order on the base layer 10.

[0081] In the decorative film 100A, the first transparent layer 20A of the first transparent layer 20A and the second transparent layer 20B contains the luminous material 21. That is, the transparent layer 20 (first transparent layer 20A) containing the luminous material 21 is located between the transparent layer 20 (second transparent layer 20B) not containing the luminous material 21 and the base layer 10. In contrast, in the decorative film 100B, the second transparent layer 20B of the first transparent layer 20A and the second transparent layer 20B contains the luminous material 21. That is, the transparent layer 20 (first transparent layer 20A) not containing the luminous material 21 is located between the transparent layer 20 (second transparent layer 20B) containing the luminous material 21 and the base layer 10. In the decorative film 100A, the second transparent layer 20B located on the upper side does not contain the luminous material 21, so that the smoothness and leveling of the second transparent layer 20B are increased, which is advantageous in terms of increasing the glossiness. In addition, in the decorative film 100B, the second transparent layer 20B located on the upper side contains the lustrous material 21, so that the amount of light that reaches the lustrous material 21 and is reflected by the lustrous material 21 increases. This is advantageous in that the effect of improving saturation can be enhanced and the amount of the lustrous material 21 contained can be reduced.
