Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION The present invention relates to
The present invention relates to a component which looks like a pearl or metal tone having high designability and can enhance visibility by emitting light of a luminous pigment when dark.

[0002]

2. Description of the Related Art Hitherto, a component using a luminous pigment has been formed by applying a paint containing the luminous pigment on a base material or molding a resin mixed with the luminous pigment. In general, luminous pigments are large in particle size and do not have a vivid color tone. Therefore, when applied to a base material as a coating material, the surface of the coating film becomes rough, resulting in poor design of parts. Further, according to the resin molding, although the whole part has a luminous property, it is difficult to make only a part of the part have a luminous property.

[0003]

The problem to be solved by the present invention is that a bright place has a vivid pearl or metal tone excellent in design, and a dark place has an inherent luminous performance of a phosphorescent pigment. It is to provide parts having.

[0004]

SUMMARY OF THE INVENTION The present invention provides a component characterized by sequentially providing a luminous pigment layer and a translucent coating layer on a substrate.

[0005] By providing a translucent film layer on the luminous pigment layer, it is possible to prevent the white color or yellow-green color tone of the luminous pigment itself from being visually recognized in a bright place, and to visually confirm the rough surface state of the luminous pigment layer surface. It is also possible to prevent light emission of the phosphorescent pigment in a dark place.

If the translucency of the translucent film layer is too low,
The amount of light incident on the luminous pigment layer is reduced, the luminous efficiency is reduced and the emitted light is also difficult to be emitted from the translucent film layer, and if the transmittance is too high, the white color of the luminous pigment itself is reduced. Or a yellow-green color tone is produced, and the roughness of the surface of the phosphorescent pigment layer significantly impairs the design, so that the transmittance of the translucent film layer is 50 to 80.
% Is preferable.

Further, in a bright place, it is effective means to prevent the color tone of the luminous pigment itself and the rough surface state from being visually recognized by utilizing light scattering. Therefore, the translucent film on the luminous pigment layer is effective. It is preferable that a glitter material is contained in the layer.

The brilliant material may be any inorganic material in the form of a powder. The particle diameter, content, and coating film thickness affect the light scattering state and the luminous efficiency of the luminous pigment. In this case, the type, the content, and the thickness of the glittering material used may be appropriately adjusted so that the transmittance of the translucent film layer is about 50 to 80%.

In particular, as the glitter material to be contained in the translucent film layer, inorganic material powder such as mica powder, metal powder such as aluminum, or alumina powder is preferable from the viewpoint of light scattering property, and particularly, From the point that light scattering is effectively performed and the color tone becomes pearl tone or metal tone, and it is possible to prevent the color tone of the luminous pigment layer and the rough surface state from being visually recognized,
It is preferred to use mica powder.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a partially enlarged view showing a coating layer structure of a component according to the present invention. After a primer layer 2 is applied on a base material 1 to improve adhesion, a coating layer 3 is formed. It is formed by coating. On this paint layer 3, a phosphorescent pigment layer 4 and a translucent film layer 5 containing a glitter material are applied and formed.

In this figure, the part where the luminous pigment layer 4 is formed is the part A of the component, and the part where only the translucent film layer 5 containing the glittering material is formed without forming the luminous pigment layer. Assuming that the part B is a part, in a bright place, the paint layer 3 and the translucent film layer 5 containing the brilliant material cause both the part A and the part B of the part to have the same color tone and express high designability. Further, when this component is used in a dark place, visibility is exhibited by the light emission of the phosphorescent pigment layer.

FIG. 2 shows an example in which a component having the same layer structure as that shown in FIG. 1 is applied to an automobile front spoiler. The substrate 1 for a front spoiler for an automobile is molded of polypropylene and is usually colored black. After applying RB195 primer manufactured by Nippon Bee Chemical Co. as a primer layer 2 to a base material 1, Primac No. 5500 BWK1 color base was applied to form a white coating layer. This white coating layer is preferable in order to prevent light emitted from the luminous pigment layer from being absorbed by the base material 1 and to improve luminous efficiency.

A luminous pigment layer 4 is formed only on the portion A where light is to be emitted on the white coating layer. The luminous pigment layer is composed of luminous pigment 440S manufactured by Dainippon Ink and Chemicals, Inc. and Primac No. It is formed by applying a paint mixed with 5500 clear.

Next, a translucent film layer 5 containing a glittering material is formed on the part A and the part other than the part A of the component to have a dry film thickness of 10 to 10.
It is formed to have a thickness of 15 μm. In the present embodiment, Primac No. A 5500BWK1 mica-based paint is applied to form a translucent film layer.
It contains mica with a particle size of ４０40 μm, and its content is about 2%, but it becomes about 6% in the dried coating film.
The transmittance of the coating is about 70%.

The vehicle front spoiler 7 having such a configuration has a white pearl metallic color tone as a whole and has excellent design. The translucent film layer 5
As a surface finish, Primac No. A clear paint layer 6 is provided by applying 5500 clear paint.

The front spoiler manufactured in this manner becomes a white-colored pearl metallic tone excellent design part so that the part A and the part B are indistinguishable in a bright state in the daytime. Then, only the portion A, which is the portion where the luminous pigment layer is applied, emits light orange light, and the presence of the front spoiler for an automobile can be visually recognized.

[0017]

According to the luminous component according to the present invention, in a bright place, the color of the luminous pigment itself can be shown without being limited to the color of the luminous pigment itself. You can see it. If a translucent film layer contains a glittering material to further enhance the design,
In a bright place, a pearly or metallic high design property is exhibited, and in a dark place, the visibility of the component can be enhanced by light emission from the luminous pigment layer. In addition, since the luminous pigment layer can be easily applied in a normal application step, there is no need for a separate step that requires a large-scale apparatus. Can be easily provided in the same part.
