The second invention is a decorative pressure-sensitive adhesive sheet in which a first layer, a second layer and a pressure-sensitive adhesive layer are laminated in this order, wherein the second layer comprises a colored translucent resin layer, 1
The layer was composed of a colored semitransparent or colored opaque resin layer, and the resin layer was removed in a pattern shape, or a transparent portion was provided in the removed portion.

According to a third aspect of the present invention, there is provided a decorative pressure-sensitive adhesive sheet in which a first layer, a second layer and a pressure-sensitive adhesive layer are laminated in this order, wherein the second layer comprises a colored opaque resin layer, and the first layer. But,
Consisting of a colored opaque resin layer or a colored translucent resin layer,
A colored transparent resin layer was provided in a portion where the resin layer was removed in a pattern shape.

According to a fourth aspect of the present invention, there is provided a decorative pressure-sensitive adhesive sheet in which a first layer, a second layer and a pressure-sensitive adhesive layer are laminated in this order, wherein the first layer comprises a colored transparent resin layer, and the second layer. Is composed of a colored opaque resin layer or a colored translucent resin layer, and the colored transparent resin layer is provided in a portion where the resin layer is removed in a pattern shape.

[0011]

[Function] When viewed with reflected light, the pattern-shaped portion
When the layer is a transparent resin layer, the color of the colored transparent resin layer or the colored translucent resin layer of the second layer is expressed, and when the first layer is the colored transparent resin layer, the colored transparent resin layer is colored. A color in which the color of the layer and the color of the colored transparent resin layer or the colored translucent resin layer of the second layer overlap each other is expressed.

On the other hand, the colored opaque resin layer or the colored translucent resin layer, which is the other portion, is
The color of the colored opaque resin layer or the colored translucent resin layer of the above layer and the color of the colored transparent resin layer or the colored translucent resin layer of the second layer overlap each other.

When viewed with transmitted light, the pattern-shaped portion is the same as when viewed with reflected light as described above, but the portion other than that is the colored opaque resin layer or the colored translucent resin layer. Only the colored opaque resin layer or the colored translucent resin layer of the first layer can be expressed because of the hiding property.

In this way, different colors are expressed by the reflected light and the transmitted light.

It can be seen, and only the color of the first layer 2a appears in the part B.

A semi-transparent adherend side is illuminated with a light source to
When viewed as transmitted light from the layer side, the portion a is similar to the reflected light, but the portion b has no transmitted light, so no color is recognized and only the shape appears.

In another embodiment of the first invention shown in FIG. 2, the first
When viewed as reflected light from the layer side, the portion C is similar to the portion A of the first embodiment, but the portion D is the first layer 2b.
The overlapping color of the second layer 3a is the main component, and the color of the adherend does not appear or appears slightly.

When viewed as transmitted light from the first layer side,

In another embodiment of the second invention shown in FIG. 4, the first embodiment
When viewed with reflected light from the layer side, the color of the second layer 3b and the adherend appear to overlap each other in the G portion, and only the color of the first layer 2a appears in the C portion. Looking at this as transmitted light from the first layer side,
The same as in the case of reflected light in the part of G, but since there is no transmitted light in the part of J, no color is recognized and only the shape appears.

In the embodiment of the third invention shown in FIGS. 5 and 6,
When viewed with reflected light from the front surface side, the portion of the colored opaque resin layer 2a or the colored semitransparent resin layer 2b in the first layer 2 is
The color tone is expressed as it is, and the pattern-shaped transparent resin layer 2c portion of the first layer 2 expresses the color tone of the colored opaque resin layer which is the second layer 3 through the transparent resin layer 2c.

In this way, the reflected light expresses different color patterns on the same sheet.

In some cases, in the colored semitransparent resin layer 2b of the first layer 2, the color tone of the colored semitransparent resin layer 2b and the color tone of the opaque resin layer of the second layer 3 overlap. It is expressed in different colors.

In the embodiment of the fourth invention shown in FIGS. 7 and 8, when the second layer is the one in which the colored opaque resin layer 3c is excluded from the pattern shape, the colored transparent resin layer 3a is provided. When viewed from the reflected light from the first layer side, the color of the colored layer is mainly the surface color of the colored opaque resin layer 3c, and the color of the first layer appears to overlap with the color of the colored opaque resin layer 3c. The colors of the layers overlap and the color of the adherend is seen through. When the first layer of the semi-transparent adherend is illuminated with a light source from the opposite side, and when viewed as transmitted light from the first layer side, the re-colored portion has a black shadow, and the dark-colored portion has the color of the colored transparent resin layer 3a. Then, the color of the first layer and the adherend are overlapped with each other, and a pattern shape appears.

When the second layer 3 is the one in which the colored transparent resin layer is provided in the portion where the colored semitransparent resin layer is removed in the pattern shape, when viewed from the reflected light from the first layer side, In the area of, the color of the colored semi-transparent resin layer 3b, the color of the adherend and the color of the first layer 2 appear to overlap, and in the area of E, the color of the first layer 2 overlaps the color of the colored opaque resin layer 3c. appear.

When the first layer 2 of the adherend which is semi-transparent is illuminated with a light source from the opposite side, and when viewed as transmitted light from the first layer side, the part of the red is the color of the colored semi-transparent resin layer 3b. The adherend is seen through because the colors of the first layer 2 overlap each other, and the color of the colored opaque resin layer 3c is not recognized in the portion of E and only the shape appears.

In this way, the reflected light and the transmitted light represent different color tones.

[0050]

As described above, according to the present invention, different color tones can be expressed when viewed with reflected light and when viewed with transmitted light.

Further, there is an effect that a pattern having different color tones can be expressed in the same sheet for both reflected light and transmitted light.
