率が小さくなって見えにくくなる。As the substrate, one made of glass or transparent resin is used. As the transparent resin, acrylic resin and polycarbonate are most suitable. The thickness of the substrate is appropriately set, but is usually about 4 to 6+++ m. The heat ray reflective layer is made of metal, alloy or metal compound by vacuum evaporation,
When the substrate is glass, it can be coated directly on the glass or coated on a film and then inserted into laminated glass by a method such as sputtering. Metals include nickel (Ni), chromium (Cr)
, titanium (Ti), aluminum (Al), gold (Au)
, silver (Ag), copper (Cu), cobalt (CO), molybdenum (Mo), etc. are used, and alloys of two or more of these metals are used, and titanium nitride is used as metal compounds. (T t N) etc. are used, but it is preferable that they have corrosion resistance.If the substrate is a transparent resin, a base coat layer of polyfunctional acrylic resin etc. should be provided in advance to improve adhesion. is preferable. The thickness of the isothermal reflective layer varies depending on the type of metal, alloy, or metal compound used, but the visible light transmittance is 3 to 1.
5%, and the solar radiation transmittance is preferably set in the range of 2 to 10%. Specifically, a range of 150 to 400 people is suitable. If there are less than 150 people, the solar radiation transmittance will be too high and heat ray reflection cannot be expected, and if there are more than 400 people, the visible light transmittance will be too low and it will be difficult to see the outside of the car from inside the car, which is not desirable. The coating layer is formed using, as a binder, a resin having excellent adhesion to metals such as acrylic esters, other acrylics, polyolefins, melamines, silicones, and polyurethanes. As a matting agent, fine powders such as silicon oxide (3i02), barium sulfate (BaS04), and calcium carbonate (CaCO3) are used, but ITO (approximately 5% by weight of 5n02
If a material with high infrared reflectivity such as In203) or 5n02 containing In203) is used, the heat ray shielding property of the resulting skylight material will be further improved. The particle size of the matting agent is lO~
A range of 50 mμ is preferred. If it is less than 10 mμ, the dispersion effect on the binder will be poor, and if it exceeds 50 mμ, the scattering effect will be small and the effect of lowering the reflectance will be reduced. Various commonly used coloring pigments can be used as the coloring pigment, but it is preferable to use a color similar to that of the heat ray reflective layer in order to prevent whitening of the surface due to the addition of a matting agent. 0 For example, if a chromium-based metal is used as a heat ray reflective layer, the transmitted color will be monochromatic, so using a black pigment such as carbon black will prevent whitening and create a natural color. A transparent color is obtained. The above-mentioned coloring pigment and matting agent are used by being blended with the above-mentioned binder, and the blending ratio is determined by the visible light transmittance (JI
It is preferable to set the solar radiation transmittance (according to JIS R320B) to be in the range of 3 to 15% and the solar radiation transmittance (according to JIS R3208) to be in the range of 2 to 10%. Specifically, the coloring pigment is 2 to 15% by weight based on the resin solid content of the binder.
is preferred, and 4 to 12% by weight is more preferred. 2% by weight
If it is less than 15% by weight, both visible light transmittance and solar radiation transmittance become too large, and if it exceeds 15% by weight, almost no light passes through, which is inappropriate. Further, the amount of the matting agent is preferably 5 to 20% by weight, and more preferably 8 to 16% by weight. This is due to the same reason as for the above colored pigments. The thickness of the matte coating layer formed as described above is 1
A range of 0 to 40 μm is suitable. If it is less than 10 μm, no heat ray reflection can be expected, and if it exceeds 40 μm, visible light transmittance decreases and it becomes difficult to see.

さくなる。By adopting the above configuration, the solar radiation transmittance is suppressed and heat rays are blocked by the heat ray reflecting layer provided on the glass or transparent resin base, for example, on the inside of the car, and the coloring pigment and matting agent are The included matte coating layer suppresses visible light reflectance and reduces the mirror effect.

As shown in FIG. 2, a roof 2 of a passenger car 1 is equipped with a skylight material 3 as a sunroof. As shown in FIG. 1, the skylight material 3 has a base 4 made of transparent resin.
A heat ray reflective layer 5 made of a nickel-chromium alloy is provided on one side of the inside of the vehicle, and a matte coating layer 6 is further provided on the lower surface thereof. The base 4 is a transparent resin plate made of polymethyl methacrylate (PMMA) and has a thickness of 4 mm. Then, in order to improve the adhesion with the heat ray reflective layer 5, a polyfunctional acrylic ultraviolet curable resin was coated on the substrate 4 and cured by irradiation with ultraviolet rays. The heat ray reflecting layer 5 is made of Hastelloy X (Ni47.3%, Cr21.
8%, Fe18.5%, Mo 9.0%, C01,5
% etc.) by sputtering. The sputtering was performed using an argon (Ar) pressure cuff x 10-' T using a normal DC magnetron sputtering device.
orr, and the discharge output IAX was 550V. Isothermal reflection l! The thickness of 5 was 200 people. After providing this heat ray reflective layer 5, the visible light transmittance was 10.4%, and the visible light reflectance (5° specular reflection) was 54.6%. The matte coating layer 6 uses a urethane-based two-component paint as a binder resin, and contains 8.0% by weight of silicon dioxide (SiO2) as a matting agent and 8.0% by weight of silicon dioxide (SiO2) as a coloring pigment based on the solid content of the binder resin. 4.5 black carbon black
A mixture of % by weight was spray coated to a dry film thickness of 20 μm and cured by heating. The skylight material 3 thus obtained has a visible light transmittance of 5.4% and a visible light reflectance of 5.7%, and the visible light reflectance is reduced by about 90% by the matte coating layer 6. be able to. Moreover, the solar radiation transmittance was 7.1%. Further, the 60° surface glossiness (JIS, Z8741) was 72.1 gloss, and the sharpness glossiness was 0.7. As mentioned above, the vehicle skylight material of this example is particularly suitable for PMM.
By providing the heat ray reflective layer 5 on the base body 4 of A, the transmission of solar radiation energy can be reduced by about 90%, and the appearance is good because a conventional shade is not required. Further, by providing the matte coating layer 6 containing a coloring pigment and a matting agent on the heat ray reflecting layer 5, light is scattered and absorbed inside the vehicle. Therefore, since there is less reflection of light on the inside of the car and the mirror effect is small, the reflection of objects and people inside the car is reduced, which reduces psychological pressure and makes it easier to see the outside of the car from the inside of the car. vice versa,
It becomes difficult to see the inside of the car from the outside. Comparative Example 1 As in the above example, a PMMA transparent resin plate was used as the substrate 4, and a layer of Hastelloy X was formed as the heat ray reflective layer 5 on the substrate 4 by sputtering. Next, we applied a urethane-based two-component paint (product name: EXP manufactured by Fujikura Kasei Co., Ltd.).
-1506), 9.0% as a colored pigment to the resin content.
A skylight material 3 was obtained by applying and curing a material containing only % by weight of carbon black under the same conditions as in the above example. The visible light transmittance of this skylight material 3 was 3.7%, the visible light reflectance was 6.2%, and the solar radiation transmittance was 7.0%. These numerical values are comparable to those of the above example, but when looking outside through the skylight material 3 from inside the car, the reflection was greater in this comparative example than in the above example. This is because in the above Examples, the reflected light is scattered and absorbed due to the addition of the matting agent, whereas in this comparative example, the reflected light is not scattered because no matting agent is added. Further, the surface glossiness was 92.3 gloss, and the sharpness and glossiness were 1.2 (in each case, the smaller the value, the less light was reflected). Both of these numerical values were higher than those of the above examples, confirming that the surface gloss was high due to the absence of a matting agent. The present invention is not limited to the above embodiments, but can also be configured as follows. (1) In the above embodiment, the heat ray reflective layer 5 and the matte coating layer 6 were provided on one side of the base body 4 on the inside of the car from the viewpoint of durability.
It is also possible to provide these on one side of the outside of the vehicle or on both the inside and outside of the vehicle. (2) In the above embodiment, the skylight material 3 is used as the roof 2 of the passenger car l.
However, in addition to the passenger car 1, it is also applicable to vehicles such as wagons and buses. [Effects of the Invention] The vehicle skylight material of the present invention sufficiently reflects heat rays, so there is no need for a shade, and the appearance is good.The mirror effect on the inside of the car is small, causing less psychological pressure, and it can also be used from the inside of the car to the outside of the car. This has the excellent effect of making it easy to see.
