Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a resin panel having a multi-layer structure for use in underwater structures such as pool panels.

[0002]

2. Description of the Related Art In recent years, a resin panel has been widely used as a decorative plate or the like for decorating the surface of a building. The resin panel includes, for example, a single-layer structure and a multi-layer structure.

[0003]

Such a resin panel may be used, for example, as a pool panel, and this single-layer resin panel has a lower saturation C ^* in water than in the atmosphere, while a plurality of resin panels are used. The resin panel having a layered structure has a higher lightness L ^* and a higher saturation C ^* in water than in air.

By the way, as in the case of a resin panel having a single-layer structure, a decrease in the saturation C ^* means that it approaches an achromatic color, which is not preferable in terms of appearance. Further, as in the case of a resin panel having a multi-layer structure, it is preferable in that the saturation C ^* is increased, but an increase in the brightness L ^* results in a light image color and lacks a sense of depth.

The present invention has been made in view of the above points, and it is an object of the present invention to provide a resin panel having a multi-layer structure capable of providing a depth feeling equivalent to that obtained in the atmosphere when used in water. Has a purpose.

[0006]

In order to solve the above-mentioned problems, a resin panel having a multi-layer structure according to the first aspect of the present invention comprises:
It has a light transmitting layer on the front side and a colored layer on the back side, and the lightness L ^* of the transmitted light of the light transmitting layer is a value of about 80 or less.

[0007]

As a result of various researches and developments, the inventor has found that even in water, the saturation C ^* does not decrease at least as compared with the atmosphere, and the lightness L ^* is made equal to or less than that of the atmosphere, thereby making it equal to the atmosphere. It was found that a feeling of depth can be obtained.

For this reason, in the invention according to claim 1, the resin panel having a multi-layer structure has a transparent layer on the front side and a colored layer on the back side, and the lightness L ^* of the transmitted light of this transparent layer is By setting the value to about 80 or less, for example, even in water, the saturation C ^* does not decrease at least as compared with the atmosphere, and the lightness L ^* is equal to or less than that of the atmosphere, and a depth feeling equivalent to that in the atmosphere was obtained.

[0009]

Embodiments of the resin panel having a multi-layer structure of the present invention will be described below in detail with reference to the accompanying drawings.

FIG. 1 is a sectional view showing the layer structure of a resin panel having a multi-layer structure. This multi-layer resin panel 1
Has a two-layer structure having a transparent layer 2 on the front side and a colored layer 3 on the back side, and the lightness L of the transmitted light of the transparent layer 2 on the front side.
^* Is set to a value of approximately 80 or less. As means for setting the lightness L ^* of the transmitted light of the transparent layer 2 to a value of about 80 or less, increasing the content% of the pigment contained in the transparent layer 2 or reducing the particle size, or There are increasing the thickness of the layer 2 and combinations thereof.

The light-transmitting layer 2 and the coloring layer 3 are made of a resin, and the light-transmitting layer 2 is made of a resin having a property of transmitting light and may be colored or may not be colored. Good. The colored layer 3 is formed of a colored resin and is colored to cover the base.

The resin used for the light transmitting layer 2 and the coloring layer 3 is preferably, for example, an acrylic resin, and as the pigment, for example, cobalt oxide based on blue and titanium oxide on white have chlorine resistance. Therefore, the resin panel 1 having the multi-layer structure can be preferably used for a pool or the like.

FIG. 2 is a schematic view showing an embodiment in which the resin panel having the multi-layer structure is used for a pool. The resin panel 1 having the multi-layer structure is used as a decorative plate on the bottom surface 11 or the side surface 12 of the pool 10. When the resin panel 1 having a multi-layer structure is used as the decorative plate of the pool 10 as described above, the saturation C ^* does not decrease at least in water as compared with the atmosphere, and the lightness L ^* is made equal to or less than A feeling of depth equivalent to medium was obtained.

Next, the resin panel of this multi-layer structure does not deteriorate at least the saturation C ^* even in water as compared with the atmosphere, and makes the lightness L ^* equal to or less than that of the atmosphere, so that a depth feeling equivalent to that in the atmosphere is obtained. The principle by which the above is obtained will be described based on FIGS. 3 to 6.

FIG. 3 is a schematic diagram of a spectrophotometer. In this spectrophotometer, a sample P of a resin panel having a multi-layer structure is put in water in a glass container 20. The light from the light projector 21 is irradiated perpendicularly to the light-transmitting layer of the sample P of the resin panel having the multi-layer structure, and the light receiver 22 is arranged at a reflection position of 45 degrees of this light. The light received by the light receiver 22 is converted into an electric signal by the detector 23 and input to the computer 24, and the computer 24 makes the lightness L
^{* And} saturation C ^* can be obtained.

When making a resin panel having a multi-layer structure having transparency and depth in the atmosphere, it is conceivable that the resin panel has a two-layer structure of a light-transmitting layer and a coloring layer. Sample P is shown in FIG. Sample P of the resin panel is adapted and a light transmitting layer P1 colored layer P2 Prefecture, as measured submerged in a glass container 20 spectrophotometric apparatus shown in FIG. 3, the lightness L ^* than in the atmosphere It was confirmed by the computer 24 that the saturation C ^* increased. Moreover, when the sample P of the resin panel has a two-layer structure, it can be confirmed that the saturation C ^* of the reflected light in water of the sample P of the resin panel is higher than that in the atmosphere for any specifications of the light transmitting layer P1. Normally, as the lightness L ^* increases, the color of the image becomes lighter and the feeling of depth decreases. Therefore, the two-layer molded plate in water cannot maintain the feeling of depth in the atmosphere.

[0017] Therefore, as shown in graph showing the relationship of the reflection light bright degree L ^* when the lightness L ^* and two layers resin panels of the translucent layer of a sample of one layer resin panel of Fig. 5, one layer resin When a pigment is added to the light-transmitting layer P1 of the sample P of the panel and the lightness L ^* of the light transmitted through only the light-transmitting layer P1 is reduced, the light-reflected lightness L ^* M1 in the atmosphere and the water in water in the two-layer resin panel are reduced. Both the reflected light brightness L ^* M2 decreases. Thus, the down is reflected light bright degree L ^* M1 and reflected light bright degree L ^* M2 in water in the atmosphere, and the lightness L ^* and two layers resin panels of the translucent layer of a sample of one layer resin panel of Fig. 6 as shown in showing the relationship between the chroma C ^* of time, become the Aya Ya or up the chroma C ^* N1 and chroma C ^* N2 of water in the air, but deep feeling out, translucent The lightness L ^* of the transmitted light of the translucent layer P2 is approximately 80 or less that the layer P2 can maintain a depth feeling equivalent to that of the transparent layer in water. As described above, when the lightness L ^* of the transmitted light of the transparent layer P2 has a value of about 80 or less, the resin panel sample P
The lightness L ^* of the reflected light in water can be made equal to or less than the value in the atmosphere, and the saturation C ^* does not decrease at least in water as compared with the atmosphere, and the lightness L ^* can be equal to or less than that in the atmosphere. The same sense of depth can be obtained.

[0018]

As described above, the resin panel of the multi-layer structure of the present invention has the light transmitting layer on the front side and the coloring layer on the back side, and the lightness L ^* of the transmitted light of the light transmitting layer is about 80 or less. Therefore, even in water, for example, the saturation C ^* does not decrease at least as compared with the atmosphere, and the lightness L ^* becomes equal to or less than that of the atmosphere, and a depth feeling equivalent to that in the atmosphere can be obtained.
