  Further, in the invention described in Patent Document 3, an undercoating layer, an intermediate coating layer, and a topcoat coating layer are sequentially formed on a floor base material, and the intermediate coating layer includes a highly bright scaly substance. It is said that. In this invention, when the floor surface is exposed to light, it is said that the decorative property can be improved by reflecting and shining on the highly bright scaly substance contained in the intermediate coating layer. It depends on the irradiation, and if it is not irradiated or is weak or depending on the angle, the decorativeness cannot be fully exhibited. In addition, it has a structure in which a three-layer coating layer is formed on a wood-based substrate. A pigment such as a pigment is applied to the base coating layer, and a highly bright scaly coat coated with titanium oxide on the intermediate coating layer. The manufacturing process is complicated and time consuming because it is necessary to heat and cure a mixture of polyester resin and cellulose derivative containing substances, and using a curable transparent paint for the top coat layer, each with a different composition. There is a problem that costs.

  In addition, in the invention described in Patent Document 4, a silver mirror film is provided on the back surface of a highly transparent light guide plate, and a part of the silver mirror film is removed and a rough surface processing is applied to the light guide plate to form a picture area. In addition, a light source such as an LED is disposed on the end face of the light guide plate, and the light source is turned on to project light from the end face of the light guide plate to the inside. In the present invention, since the pattern formed on the pattern area is scattered by the rough surface (unevenness) formed on the light guide plate by the projection light so that the pattern floats on the surface by the light. Although it is possible to exhibit the properties, the light guide plate must be roughened to form a pattern area, and a light source such as an LED must be disposed on the end face of the light guide plate. Not only is labor and expense required, but also an installation space for the light source is required, which is generally unsuitable as a flooring that can be widely adopted.

And the invention disclosed in the above-mentioned patent document is any invention,
The decorative element is a prescribed pattern or pattern that has been given in advance by printing, painting, surface processing, etc. during the production process, and has been given even if there is a visual change due to the viewing direction, light irradiation, etc. The pattern and the picture itself do not change.
