The thickness of the light reflection layer is 5 to 5 based on the cured film.
The thickness is preferably 300 μm, particularly preferably in the range of 8 to 200 μm. The coating layer can be cured by setting appropriate conditions depending on the type of the resin composition. The thermosetting resin can be crosslinked and cured by heating at a temperature of about 100 to about 170 ° C. for about 10 to about 40 minutes.

The light reflecting layer preferably has a mirror surface. The specular surface is, for example, a regular reflection type smoothness meter (manufactured by Toyo Seiki Co., Ltd.) (contact rate of 80% or more is preferable), 7
It can be measured using a 5 ° gloss (preferably 90 or more), a surface roughness meter (preferably a depth of 0.1 μm or less) and the like.

The regular reflection type smoothness meter utilizes the property that the incident light is totally reflected at the non-contact portion of the light reflection layer surface pressed onto the prism and the incident light is diffused at the contact portion. The contact rate is optically measured. At this time, due to the optical properties, even if the light reflection layer surface does not contact the prism surface, light will pass through the air layer when approaching the wavelength used, and if the wavelength used becomes longer, the contact rate will increase. Will increase. Therefore, although it is necessary to specify the wavelength to be used, light having a wavelength of 0.5 μm is generally used.

Further, the 75 ° gloss is measured according to JIS K-54.
According to the 75 degree specular gloss of 00 7.6 (1990),
The degree of gloss of the coating film is 75 for the incident angle and the acceptance angle, respectively.
The reflectance is measured in degrees, and is expressed as a percentage when the glossiness of the reference surface of the specular glossiness is 100.

A chromatic color layer having transparency (d); a chromatic color layer having transparency (d) is a layer which imparts design, three-dimensional effect, pattern, etc. to the film decorative material of the present invention. is there. The chromatic colored layer may be a single layer or a multilayer.

The chromatic color layer (d) having transparency is a transparent layer which can be seen through from the surface side of the light reflecting film decorative material regardless of whether it is a single layer or a multilayer.

As the transparent chromatic color layer (d), at least one layer of the transparent chromatic color layer (d) is a high chroma chromatic color containing a chromatic color pigment having a Munsell chroma of 8 or more. Chromatic color layer (i) having a colored layer of, and a chromatic color layer having transparency (d)
Is a multi-colored chromatic coloring layer (ii) including two or more layers and at least two chromatic coloring layers having transparency different in hue, and a chromatic coloring layer having transparency ( At least one layer of d) is a transparent interference chromatic coloring layer (iii) containing scaly mica powder, and a chromatic coloring layer in which two or more kinds of these chromatic coloring layers are combined. And so on.

The colored layer (i) of high chroma chromatic color is formed by the same curable resin as described above, and a high chroma colored composition containing 8 or more, preferably 14 or more chromatic color pigments, although Munsell chroma varies depending on the hue. Although the Munsell chroma obtained depends on the hue, there are 8 or more, preferably 14 or more chromatic color hardened layers. The Munsell chroma is the chroma (saturation) specified in the Munsell display system, and
Specified by S Z 8105.

The color pigment having a Munsell chroma of 8 or more contained in one layer can be used in combination with a color pigment having 2 or more Munsell chromas of 8 or more, but Munsell chromas having different hues can be used. When 8 or more coloring pigments are used, the color tends to become turbid and dull, resulting in reduced saturation (for example, a combination of red and blue, a combination of yellow and blue, a combination of red and green). It is not preferable.

The color pigment having a Munsell chroma of 8 or more can be appropriately selected depending on the design property required for the conventionally known color pigment having a Munsell chroma of 8 or more.

The high-chroma chromatic coloring layer (i) is the light which is the incident light transmitted from the surface of the light-reflecting film decorative material, transmitted through the high-chroma chromatic coloring layer, and reflected by the light-reflecting layer (c). Again passes through the colored layer of high chroma chromatic color, and the transmitted light is extracted as light with design. The chromatic color layer has a high saturation in a wide range of low brightness to high brightness as compared with a normal chromatic color layer having a chroma, and thus a clear color can be expressed.

Further, since the light reflection layer (c) is used as the underlayer, a large amount of reflected light is applied to the chromatic color layer having chroma, and the saturation is high in a wide range of low brightness to high brightness. You can express clear colors.

The polychromatic chromatic coloring layer (ii) is a layer containing at least two chromatic coloring layers having different hues and having transparency. These layers have a hue different from that of a composition such as a paint or an ink that forms a transparent chromatic colored layer formed by blending a curable resin and a chromatic pigment similar to the above. It is obtained by forming two colored layers using the composition containing the chromatic color pigment.

Conventionally, in a chromatic color layer in which pigments having different hues are mixed in one layer, color turbidity due to color mixing causes a high brightness and a dull color to be expressed. In the chromatic color layer (ii), by combining chromatic color layers having different hues as different layers, even if light transmitted through the chromatic color layers having different hues is mixed, the lightness can be improved. Utilizing the property of light that does not deteriorate,
It is possible to form a chromatic color layer having high saturation.

Further, since the light reflecting layer (c) is used as the underlayer, the polychromatic chromatic coloring layer (ii) is irradiated with a large amount of reflected light, so that the saturation in a wide range of low brightness to high brightness is obtained. Because it is high, you can express a clear color.

The interference chromatic coloring layer (iii) is a transparent layer containing scaly mica powder. The colored layer is, for example, a composition such as a curable resin similar to the above, a scaly mica powder, a paint or an ink that forms a transparent chromatic colored layer by mixing a chromatic pigment if necessary. It can be formed using an object.

Those in the range of m are preferable. The titanium oxide coating thickness of the titanium oxide-coated mica used is usually preferably in the range of 90 to 160 nm based on the optical thickness, and 40 to 70 nm based on the geometrical thickness.

The amount of the scaly mica powder coated with the metal oxide is not strictly limited, but it is usually 3 to 20 per 100 parts by weight of the total solid content of the resin composition.
It is preferably in the range of 7 to 13 parts by weight, especially 7 to 13 parts by weight.

If necessary, the composition for forming the chromatic color layer (d) having transparency further includes a coloring pigment, a metallic pigment, an ultraviolet absorber, a fluidity, to the extent that the transparency of the coating is not impaired. Conditioning agent, anti-repellent agent, anti-sagging agent, antioxidant, ultraviolet stabilizer, matting agent, polish, preservative, curing accelerator, curing catalyst, anti-scratch agent, defoaming agent, solvent, silver plated glass Flakes, titanium-coated graphite, metallic titanium flakes, and other additives for paints can be blended.

The film thickness is based on the cured coating film and is 50 μm to 500 μm, especially 60 μm in a single layer or total film thickness.
It is preferable that the thickness is in the range of 200 μm. The coating layer can be cured by setting appropriate conditions depending on the type of the resin composition. The thermosetting resin can be crosslinked and cured by heating at a temperature of about 100 to about 170 ° C. for about 10 to about 40 minutes.

The film thickness is preferably 5 to 100 μm, particularly 8 to 80 μm based on the cured coating film. The coating layer can be cured by setting appropriate conditions depending on the type of the resin composition. The thermosetting resin can be crosslinked and cured by heating at a temperature of about 100 to about 170 ° C. for about 10 to about 40 minutes.
