FIG. The light-reflecting layers of Examples 1, 4 and 7 (invention product) and Comparative Examples 1 to 4 (comparative product) were measured using an aluminum-deposited polyester film (corresponding to the unprinted portion of the cured resin layer) as a control sample. It is a figure which shows the relative reflectance (wavelength region 200-2200 nm) measurement result after providing.

Embodiments of the present invention will be described in detail.
As shown in FIG. 1, in the glittering decorative sheet of the present invention, a cured resin layer 2 containing a matting agent in a dispersed state in a transparent resin is formed on one surface (back surface side) of a transparent substrate sheet 1. It is partially provided so that characters, designs, patterns, etc. are expressed, and on the surface there is also a non-applied part (part other than the cured resin layer 2) where the cured resin layer 2 is not provided, A light reflecting layer 3 is laminated on the entire surface of the transparent substrate sheet 1 so as to cover both the cured resin layer 2 and the non-coated portion.

  In the present invention, when observed from the surface side of the transparent substrate sheet 1, light is reflected inside the cured resin layer 2 in the portion where the light reflecting layer 3 is provided with the cured resin layer 2 containing the dispersed matting agent. In a non-coated part where the cured resin layer 2 is not provided, being scattered and observed as a matte-like metallic luster, the light-reflecting layer 3 directly laminated on the back side of the transparent substrate sheet 1 produces a mirror-like metallic luster. Observed.

  In such a glittering decorative sheet of the present invention, the weight ratio of the matting agent contained in the cured resin layer 2 is in the range of 3 to 17 parts by weight with respect to 100 parts by weight of the solid content of the transparent resin component of the cured resin layer. The range of 4 to 16 parts by weight is particularly preferable. At this time, when the content of the matting agent in the cured resin layer 2 is less than 3 parts by weight, the matte-like metallic luster is lost and reflected light is almost the same as the mirror-like metallic luster. If it exceeds 1, the matte metallic luster part is observed in white and the metallic luster is lost, which is not preferable. In this invention, it is preferable that the haze value of the part in which the cured resin layer 2 exists in the back surface side of the transparent base material sheet 1 is 13 to 37% of range.

  In the present invention, examples of the transparent base sheet 1 made of a transparent material include, but are not limited to, a polyester sheet (polyethylene terephthalate sheet), a polypropylene sheet, and a polyvinyl chloride sheet. Moreover, the thickness of the transparent base material sheet 1 can also be suitably selected according to a use.

  The cured resin layer 2 provided on the back side of the transparent base sheet 1 generally has a uniform matting agent in transparent resin inks such as acrylic, urethane, vinyl, polyamide, and nitrocellulose. The matt medium ink dispersed in is applied to the back surface of the transparent substrate sheet 1 in the form of letters or patterns by gravure printing, which is a known technique, and dried, and the general layer thickness is 1 to 5 μm. The thickness is preferably 2 to 3 μm. A commercially available product can be used as such a matte medium ink.

  In the present invention, as the matting agent, various inorganic oxides capable of observing a matte metallic luster by appropriate light scattering when observed from the surface side of the transparent substrate sheet 1 can be used. The average particle diameter of the inorganic oxide Is preferably in the range of 1 to 10 μm. Particularly preferred as the matting agent is silica particles, and examples thereof include dry silica and wet silica. The average particle diameter of the silica particles is particularly preferably in the range of 4 to 5 μm. The average particle diameter is measured by a laser diffraction particle size distribution measuring device.

The light reflecting layer 3 in the present invention is preferably formed by vacuum-depositing a metal such as aluminum on one surface (back surface side) of the transparent substrate sheet 1 provided with the cured resin layer 2. In the glittering decorative sheet of the present invention, only the difference in metallic luster between the portion where the cured resin layer 2 is present and the portion where the cured resin layer 2 is not present (whether it is specular or matte) is observed by the light reflecting layer 3. Instead, as shown in FIG. 1, the light reflection layer 3 has a level difference (unevenness) corresponding to the thickness of the cured resin layer 2, so that the difference in the light reflection surface in the sheet thickness direction. When the image is observed from the transparent base sheet 1 side, a sense of depth is imparted between the mirror-like metallic luster portion and the matte-like metallic luster portion, resulting in a three-dimensional visual effect.
At this time, even if a character or a pattern is expressed by a matte metallic luster in a portion where the cured resin layer 2 exists, a character or a pattern is expressed by a mirror-like metallic luster in a portion where the cured resin layer 2 does not exist Good. In addition, although the thickness of this light reflection layer 3 can be selected suitably, the general layer thickness in the case of a metal vapor deposition layer is about 10 nm-about 500 nm.

In the present invention, the cured resin layer 2 may be arranged in a regular pattern pattern on the transparent substrate sheet 1 or may be arranged in an irregular pattern pattern. In the present invention, when the cured resin layer 2 is provided on the back side of the transparent base sheet 1 in an irregular and fine pattern pattern such as granite, the gloss and matte tone of vapor deposition are finely woven for each small pattern, On the substrate, the texture is smooth but uneven.
Further, when the cured resin layer 2 is provided in a portion other than the dots so that the dots (dots) having a diameter of about 1 mm are regularly arranged, the glossy dots are regularly arranged on the matte silver, and the high designability and three-dimensionality. It will bring a feeling.

FIG. 2 shows the glitter of the present invention having a layer structure in which an adhesive layer 4 and a release liner 5 are sequentially laminated on the light reflecting layer 3 side (back side) of the transparent base sheet in the glittering decorative sheet of FIG. A side view of the decorative sheet is shown, and this pressure-sensitive adhesive layer 4 is generally formed by applying a pressure-sensitive adhesive, preferably an acrylic pressure-sensitive adhesive, and thereby the glittering decoration of the present invention. The sheet can be attached to an arbitrary object.
In the present invention, as shown in FIG. 2, a release liner 5 is generally laminated for the purpose of protecting the pressure-sensitive adhesive layer 4, and a release agent is coated on the surface of the release liner 5. Commercial products are available. At this time, the surface of the pressure-sensitive adhesive layer 4 on the side of the release liner can be formed with irregularities in the mesh shape of a Tyler standard sieve to improve workability such as temporary fixing at the time of sticking and air release performance.

Further, the glittering decorative sheet of the present invention may have a configuration in which a printing ink layer is provided on the other surface (front side) of the transparent base sheet 1. FIG. A side view of the glittering decorative sheet of the present invention having a layer structure in which a printing ink layer 6, an adhesive layer 7, and a transparent laminate substrate 8 are provided on the surface side of the transparent substrate sheet 1 in the glittering decorative sheet is shown. Has been. Under the present circumstances, even if the printing ink layer 6 is a layer provided by printing using transparent coloring inks, such as urethane type, a vinyl type, a polyamide type, and a nitrocellulose type, it uses the coloring ink which does not have transparency. Although a layer provided by printing may be used, it is preferable to use a colored ink having transparency in order to express characters and designs having a metallic feeling.
Further, as the pressure-sensitive adhesive layer 7, a commercially available acrylic pressure-sensitive adhesive (particularly a strong pressure-sensitive adhesive type) is generally used, but is not limited thereto.
Further, the transparent laminate substrate 8 may be a film substrate having transparency, and is not limited, but as a transparent laminate substrate that is generally used, a polyethylene terephthalate film, a biaxially stretched polypropylene film, or the like is used. Can be mentioned.

In the case of the glittering decorative sheet of the present invention having the layer configuration of FIG. 3, the printing ink layer 6 is located on the front surface side (observation side) of the transparent substrate sheet 1, and the cured resin is disposed on the back surface side of the transparent substrate sheet 1. Since the layer 2 and the light reflecting layer 3 are located, the character or the pattern expressed by the printing ink layer 6 is more than the character or the pattern having the metallic luster of the specular or matte tone by the light reflecting layer 3. It is observed at a position close to the observer (front position). In addition, since the mirror-like metallic luster and the matte metallic luster are simultaneously observed by the light reflecting layer 3, it seems that the character and the pattern expressed by the printing ink layer 6 are three-dimensionally raised to the observer. It is felt and the design is particularly excellent.
Hereinafter, the present invention will be specifically described with reference to production examples of the glittering decorative sheet of the present invention, but the present invention is not limited thereto.

[Measurement of total light transmittance and haze value of glittering decorative sheet when content of matting agent (silica particles) is changed]
As the transparent substrate sheet, a commercially available polyester film (PET, thickness: 50 μm, surface: easy adhesion primer treatment, back surface: corona treatment) was prepared.
Further, as the ink of the cured resin layer, a commercially available mat medium ink in which silica particles having a particle diameter of 4 to 5 μm are uniformly dispersed (acrylic transparent resin component: silica particles = 83.1: 16.9 (weight ratio)) On the other hand, a commercially available medium ink (containing an acrylic transparent resin component) not containing a matting agent (silica particles) was prepared as an achromatic dilution ink.
Inks having the compositions described in Table 1 below were prepared by changing the mixing ratio of the matte medium ink and the medium ink. At this time, 10 parts by weight of an isocyanate curing agent was added to each ink with respect to 100 parts by weight of the acrylic transparent resin component.
And each ink was apply | coated to the one surface (back surface side) of the said polyester film by gravure printing (coating thickness 2-3 micrometers), it dried, and 11 types of measurement samples (Examples 1-7, comparison) Examples 1-4) were prepared, and the total light transmittance and haze value were measured for each sample. The results are summarized in Table 1.

[Evaluation of glitter and three-dimensional effect]
Using the ink having the composition of Example 1, Example 4, Example 7, and Comparative Examples 1 to 4, a granite-like irregular pattern is applied to the back side of the polyester film by gravure printing, and then dried. Then, a cured resin layer (layer thickness: 2 to 3 μm) was formed. And the light reflection layer was formed by vapor-depositing aluminum with the vacuum evaporation method on the whole surface of the film in which this cured resin layer was formed, and the designability evaluation sample was produced.
In the present invention, the thicker the cured resin layer, the more three-dimensional sense of depth is increased. However, from the viewpoint of mass productivity and economy, a thin coating is preferably applied by gravure printing. In addition, the curable resin layer in the present invention may be thermosetting, but an ultraviolet curable resin can be appropriately used when selecting a transparent substrate having poor heat resistance.
In Table 2 below, together with the total light transmittance and haze value measured previously (values in Table 1), the evaluation results of the visual design properties of the above evaluation samples are described.
In addition, the criteria for determining the glitter in this design evaluation are:
○: Good metallic luster appearance is seen in the cured resin layer part,
Δ: A slight metallic luster appearance is seen in the cured resin layer part.
X: The cured resin layer portion is emphasized white, and the appearance of metallic luster is not seen,
The criteria for the three-dimensional effect are
○: Good visual depth is seen when observing a specular / matte metallic luster.
Δ: A slight visual depth is observed when observing a specular / matte metallic luster.
X: The matte metallic luster is too thin to show a visual depth.

  From the results of Table 2 above, it was confirmed that the optimal content of the matting agent (silica particles) with respect to 100 parts by weight of the solid content of the transparent resin component was 3 to 17 parts by weight. Moreover, it turned out that the optimal haze value of the part (matte tone part) in which the cured resin layer exists of the glittering decorative sheet in which good glitter and stereoscopic effect are observed is 13 to 37%.
