[Examples]

In the following, the present invention will be more specifically described by the examples, but the present invention is not limited by the examples.

(Example)

A sample of the decorative sheet was produced as follows.

A transparent polycarbonate film (addition of an adhesive layer, thickness: 0.25 mm) was prepared as a transparent film.

A titanium white ink is applied to the back surface of the transparent sheet, and then cured by UV irradiation. Next, the UV lithographic ink (silver) is imparted in a partially overlapping manner by a UV lithography machine, and then UV-irradiated to harden it. Similarly, the UV screen printing ink is imparted by a screen printing machine (silver Then, it is hardened by UV irradiation. In addition, UV lithographic inks (silver) and UV screen printing inks (silver) are only slightly different colors.

Thereby, the first illuminating portion and the second illuminating portion are formed on the back surface of the transparent sheet, and the first brilliance portion is formed of a layer of a white layer and a plurality of bright pigments, and the second brilliance portion is only composed of A layer formed by a plurality of bright pigments. In addition, this is equivalent to the decoration sheet 500 shown in FIG. 7 except that the first brilliance portion first color layer 411 of the first brilliance portion 401 and the second brilliance portion first color layer 421 of the second brilliance portion 402 are removed.

Further, the concentration per unit area of the titanium white ink and the UV lithographic ink (the ratio of the dots) was replaced by those shown in Tables 1 and 2, and the same production was carried out.

(evaluation method)

According to ASTM specification E2194-03, the brightness (L value) in the angles of 15 degrees and 110 degrees is measured from the front side of the first brilliance portion and the second brilliance portion of the transparent sheet.

The relationship between the concentration of the titanium white ink (white layer) and the UV lithographic ink (layer formed of the bright pigment) in the first illuminating portion and the brightness (L value) in 15 degrees and 110 degrees is shown in the table. 1. The relationship between the concentration of the UV lithographic ink (layer formed of the bright pigment) in the second brilliance portion and the luminance (L value) in 15 degrees and 110 degrees is shown in Table 2. Further, the relationship between the concentration of the titanium white ink (white layer) and the UV lithographic ink (layer formed of the bright pigment) in the first brilliance portion and the luminance (L value) in 15 degrees is shown in the 10th. The relationship between the concentration of the titanium white ink (white layer) and the UV lithographic ink (layer formed of the bright pigment) in the first illuminating portion and the brightness (L value) in the 110 degree is shown in Fig. 11. The relationship between the concentration of the UV lithographic ink (layer formed of the bright pigment) in the second illuminating portion and the brightness (L value) in 15 degrees is shown in Fig. 12, and the UV lithography in the second illuminating portion is shown. The relationship between the concentration of the ink (the layer formed of the bright pigment) and the brightness (L value) in the 110 degree is shown in Fig. 13.

Tables 1 and 2 and 9 to 12 clearly show that the luminance (L value) does not largely change even if the concentration of the bright pigment is changed without changing the second brilliance portion of the white layer.

On the other hand, the first brilliance portion having the white layer largely changes the luminance (L value) by the concentration of the white layer.

It is known that especially when the concentration of the titanium white ink exceeds 6%, the white layer causes a large change in brightness. Further, in the first bright portion, the test was carried out in the case where the concentration of the UV lithographic ink was 50%, but the result was the same as in the case of 50%. In addition, the layer formed by printing a UV lithographic ink (silver) by a UV lithography machine and the layer formed by printing a UV lithographic ink (silver) by a screen printing machine, on the contrary, the same test, but the same The result.

Therefore, as in the decorative sheet according to the present invention, it is possible to present a difference in light and dark depending on the viewing angle by providing a white layer, or to present a three-dimensional feeling due to light and dark.

Further, Fig. 14 is a photograph of an example of a decorative sheet using the principle of the present invention.
