Abstract

PROBLEM TO BE SOLVED: To obtain a light storage color coating material which can maintain the particles of a light storage medium in the diffused state in a coating layer without their precipitation in the process of drying the light storage color coating material and does not damage a colored material and a patterned material when a light storage pigment is directly coated even on the colored material and the patterned material without applying an undercoat thereto and can retain a constant luminance with high light storage efficiency during the long light-emitting period of time. SOLUTION: A light storage medium, a dispersing agent, and a suspension stabilizer are mixed with a coating stock solution obtained by mixing a curing agent with a mixture of a color pigment with a synthetic resin, and the particles of the above light storage medium are continued to maintain the diffused state in the layer of the above mixture of a color pigment with a synthetic resin by the action of the above dispersing agent and the above suspension stabilizer in the process for the above mixture of a color pigment with a synthetic resin to dry.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a luminous paint which emits light in the dark when irradiated with light, and more particularly to a color luminous paint having a high luminous efficiency and a long luminous time.

[0002]

2. Description of the Related Art Conventional phosphorescent color paints are made by mixing a color pigment, a phosphorescent agent, and an anti-settling agent with a clear paint, but as shown in FIG. , Since the phosphorescent agent 12 has a relatively large specific gravity,
As the time elapses, the luminous agent 12 precipitates on the base 13 side, and the color pigment 11 covers the surface. As a result, light and ultraviolet rays are blocked by the color pigment 11, and the luminous agent 12 cannot absorb light and ultraviolet rays sufficiently, so that it is difficult not only to maintain a constant illuminance but also to reduce the emission luminance. In addition, when the color pigment 11 is applied thickly, it does not emit light and there is a defect in the smoothness of the painted surface.

[0003] Further, as shown in FIG.
By spraying a transparent luminous paint on the transparent luminous film 23 disclosed in JP-A-238168 and drying it sufficiently, and then spraying the color pigment 21, the color looks like a color luminous film in the daytime, but luminous in the dark. The agent 22 emits light only in a color close to pale yellow. In addition, when the color pigment 21 is applied thickly, the refraction of light cannot be sufficiently utilized, so that the luminance may be reduced.

[0004] In addition, when a color or pattern is applied, the luminance is not constant. Therefore, it is necessary to deposit a white paint on the color or pattern once.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is capable of keeping the state of the phosphorescent particles dispersed in the paint layer without sedimentation in the process of drying the color phosphorescent paint,
Even if a luminous pigment is applied directly on a color or pattern without applying a base coat with color paint, the luminous efficiency is high and a constant brightness with a long luminous time is maintained without damaging the color or pattern. The purpose of this invention is to obtain a color luminous paint that can be used.

[0006]

DISCLOSURE OF THE INVENTION The present invention has been made in view of the above-mentioned point of view, and its main constitution is to provide a stock solution of a pigment synthetic resin mixed with a curing agent, a phosphorescent agent and a dispersant, Provided is a color phosphorescent paint in which an anti-settling agent is mixed, and the particles of the luminous agent are kept dispersed in the pigment synthetic resin layer by the action of the dispersant and the anti-settling agent in the process of drying the pigment synthetic resin. What you want to do.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below in detail with reference to FIG. In the color luminous paint according to the present invention, a mixture of a color pigment and a synthetic resin at a required ratio is used as the pigment synthetic resin 1. A color luminous paint is prepared by mixing a dispersant and an antisettling agent in addition to the luminous agent 2 with such a pigment synthetic resin 1.

A. This color phosphorescent paint is plastic,
When applied to the substrate 3 such as carbon or molded product: a powder-like phosphor is used as the phosphorescent agent 2, but in addition to the phosphorescent agent proposed by the inventor of the present invention (JP-A-10-147777), Picarico (CP-05, C
P-10), amity phosphorescent pigments and the like can be used.

As the pigment synthetic resin, the NSP ink 7000-1 series manufactured by Jujo Chemical Co., Ltd. may be used, but it can be prepared in the following mixing ratio. 1) Pigment 0% to 40% 2) Synthetic resin 20% to 80% 3) Xylene 1% to 5% 4) Propylene glycol monomethyl ether 5% to
10% 5) Cyclohexanone 25% to 50% 6) Aromatic mixed hydrocarbon 10% to 20%

[0010] Further, as a dispersant and an anti-settling agent,
JA-141 A slow drying compound is used.

B. This color phosphorescent paint is
Paper, film and base materials for products that require bending 3
When applied to: The phosphorescent agent 2 is the same as that in the above-mentioned A case.

The pigment synthetic resin may be EXG Ink 3500-1 series manufactured by Jujo Chemical Co., Ltd., but can be prepared in the following mixing ratio. 1) Pigment 0% to 50% 2) Synthetic resin 20% to 50% 3) Cyclohexanone 20% to 80% 4) Ethylene glycol monobutyl ether 5% to 1
0%

Further, the same dispersant and anti-settling agent as used in the case A are used.

Using the above materials, a pigment synthetic resin 80%
To 90%, 5% to 7% of hardener and 3% to 1 of anti-settling agent
A 10% to 20% slow-drying compound mixed with 5% was mixed to prepare a stock solution of paint, and the weight of this stock solution of paint was adjusted to 100%.
In this case, the weight of the luminous agent was mixed at a ratio of 50 to 100 to prepare a color luminous paint.

The color luminous paints obtained as described above are all the same luminous agent (Pikarico CP manufactured by Chemitech Co., Ltd.).
-05), which is the same as the conventional luminous paint which is applied separately from the luminous paint and the color pigment portion and the luminous paint which are applied on the undercoat of the white paint. The emission time for the time light irradiation did not change.

In this case, the light emission luminance was increased by increasing the weight of the luminous agent.

When the color luminous paint according to the present invention is applied, during the process of drying the slow-drying compound and the pigment synthetic resin, the particles of the luminous agent are formed by the action of the dispersant and the precipitation inhibitor. Continue to keep the state of uniform diffusion without precipitation in the resin layer.

Therefore, conventionally, by separately printing or applying a color pigment and a luminous agent, a color pigment portion and a luminous paint portion are clearly distinguished, and the luminous portion emits light yellow in the dark. there were.

By using the color luminous paint according to the present invention, it is possible to easily print and apply without separating the color pigment and the luminous agent, and to produce a color-integrated full-surface molded product to emit light in color. it can.

[0020]

In the color luminous paint according to the present invention, the undercoating with a white paint is not required to separate the color portion from the luminous portion and to increase the luminance of the luminous agent in a bright state. In addition, the color and pattern can be visually recognized, and in the dark, the coated surface of the object to be coated can be illuminated with the color phosphorescent pigment.

Further, since no thinner or the like is used, it can be used for a plastic chip or a fiber product and emits color light.
