According to a first aspect of the present invention, there is provided a decorative plate for an automobile, comprising: a rectangular unit in which black vertical stripes are spaced apart from each other; and a unit in which black horizontal stripes are spaced apart from each other. A checkered pattern layer consisting of vertical and horizontal stripes vertically aligned on the front and back of a transparent plastic plate, with a transparent plastic coating layer on the front checker pattern layer and an opaque plastic layer on the back checkerboard layer It is characterized in that a coating layer is laminated.

As in the second aspect, it is preferable that the vertical stripes and the horizontal stripes in the first aspect have a thin center portion and a thick end portion.

According to a third aspect of the present invention, one of the vertical stripes and the horizontal stripes in the first aspect may have a thick central portion and a narrow end portion, and the other may have a narrow central portion and a thick end portion. is there.

In the above decorative plate for automobiles, the vertical stripes and the horizontal stripes in a checkered pattern are slightly raised from the transparent plastic plate. For example, when light is applied from the front, the horizontal stripes shine and appear thin or thin. Then, the horizontal stripe units appear white, and the vertical stripe units that are not affected by light are remarkably expressed as shown in FIG. 5B. In this case, when the horizontal stripes are narrow at the center and thick at the ends as in claim 2, the center of the horizontal stripes is particularly shiny and white.
Looks like (c).

When the surface of the decorative plate is viewed obliquely from above, the checkerboard pattern on the back surface looks like a shadow, the checkerboard pattern on the front surface is embossed, or the checkered vertical or horizontal stripes on the front and back are partially formed. Some parts look dark because they overlap. In addition, when the vertical stripes and the horizontal stripes are as described in claim 2, one side of the vertical stripes and the horizontal stripes shines and becomes white, and a step pattern as shown in FIG. 5D appears. Also, the checkerboard stripes on the back surface are seen through the transparent portions (non-printed portions) between the stripes, and the patterns of FIGS. 5B, 5C, and 5D are more clearly expressed. There is also.

Further, when one of the vertical stripes and the horizontal stripes is made thicker at the center and thinner at the ends, like a convex lens, and the other is made thinner at the center and thicker at the ends like a concave lens.
A stripe unit having a thick central portion is extremely dark, and a stripe unit having a narrow central portion is lightly expressed, so that a clearer checkerboard pattern is obtained.

[0012]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As a transparent plastic plate, an acrylic resin plate, a vinyl chloride resin plate and the like are generally used.
0.5 mm to 5 mm is used.

The checkered patterns on the front and back are screen printed.
The ink used depends on the application, but uses a mixture of acrylic resin and vinyl resin as the main raw material and a black dye. A dark color such as dark gray, dark blue, or brown may be used as the black dye. Also, one unit of the checkered pattern has a side of 2 to 10 mm, and black stripes printed at intervals in one unit are linear with the same width, a convex lens with a thick central portion, and conversely a central stripe. There are a concave lens type with a thin part, a propeller type with a narrow middle part, and the like. Each of the stripes has a unit area of 6
It is preferable to set it to about 70 to 70%.

The front transparent plastic coating layer and the rear opaque plastic coating layer are applied by screen printing or spray coating. In this case, the same ink as the checkered pattern is used, and the paint used is a urethane resin type, an acrylic resin type, or a lacquer type. Also, the ink or paint of the opaque plastic coating layer on the back side should be of medium brightness because if the brightness is too low, the stripe pattern will be unclear and if it is too high, the image of the actual carbon fiber board will be lost. preferable.

Next, an embodiment of the present invention will be described in detail with reference to FIGS. 1 and 2 are enlarged views showing a part of an automobile decorative plate according to the present invention. FIG. 1 is a plan view, and FIG. 2 is an enlarged vertical sectional view thereof.

As shown in FIGS. 1 and 2, vertical stripes 1 and horizontal stripes 2 each having a concave lens shape having a thin center portion and a thick end portion are formed by using an ink obtained by mixing a black dye with an acrylic resin as a main material. Checkered layers 5 and 6 composed of units 3 and 4 represented at intervals are printed on the front and back of an acrylic plate 7 having a thickness of 2 mm so that vertical stripes 1 and horizontal stripes 2 are vertically aligned. Next, a transparent plastic coating layer 8 is formed with a transparent acrylic resin ink on the surface of the checkered pattern layer 5 on the front surface, and white and black dyes are mixed into the acrylic resin on the surface of the checkered pattern layer 4 on the back surface. An opaque plastic coating layer 9 is formed using an acrylic resin ink prepared to be gray.

The vertical stripes 1 and the horizontal stripes 2 in the above embodiment are used.
Has the same stripe pattern, but one stripe is thicker at the center,
In some cases, the stripes are thin at the ends.

The vertical stripes 1 and the horizontal stripes 2 are of a linear shape having the same width as shown in FIG. 4A, a propeller shape having a narrowed middle portion as shown in FIG. 4
(2) depending on the shape of the non-printed portion.

[0019]

The automotive decorative plate according to the present invention is embodied in the form described above, and has the following effects.

In the present invention, since the checkered vertical stripes and horizontal stripes are slightly raised from the surface of the acrylic plate, the horizontal stripes appear thin or thin, and the vertical stripes are remarkably expressed according to the light hit condition, and the clear checkerboard is clearly displayed. A pattern appears. Also,
When the surface of the decorative plate is viewed obliquely from above, the checkered pattern on the surface appears to be raised, or the checkered vertical or horizontal stripes on the front and back are partially overlapped with each other, and the portion looks dark. That is, three-dimensional and different checkerboard patterns are expressed, such as a carbon fiber plate, depending on how light is applied and the viewing direction.

Further, when the vertical stripes and the horizontal stripes are formed to be thick at the center and thin at the ends, a checkerboard pattern having a three-dimensional appearance similar to a woven pattern of a carbon fiber plate is more remarkably formed. Can be expressed.

Further, when one of the vertical stripes and the horizontal stripes has a thick central portion and a narrow end portion, and the other has a narrow central portion and a thick end portion, The former stripe pattern unit is extremely dark, and the latter stripe unit is lightly expressed, so that a clearer checkerboard pattern can be expressed.
