Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a black light illuminating decorative plate formed by applying fluorescent ink that emits light and displays upon receiving ultraviolet rays.

[Prior Art] Recently, there has been an increasing demand for various measuring instruments installed in automobiles or decorative plates provided around these measuring instruments, and the applicant of the present invention has developed new measuring instruments for automobiles. It is being advanced. In its development there has been provided an instrument, a dial of an instrument, or a veneer that is located around a group of instruments, which when exposed to UV light emits light over its entire surface to produce effective brightness and aesthetics.

[Problems to be Solved by the Invention] However, as in the case of the decorative plate, fluorescent ink that is excited and emits light by receiving ultraviolet rays is applied to the entire surface of the decorative plate material having a relatively large area. It is difficult to apply uniformly so that the whole has uniform brightness.
That is, for example, as shown in FIG. 3, a resin decorative plate material or the like that is mounted around a general automobile meter is screwed with a mounting window 1 of the instrument and a mounting screw 3 for mounting the decorative plate 2 on the vehicle body. Since the decorative plate 2 is made of resin, a “sink” 5 (a dent) is generated on the surface of the decorative plate 2 and the surface of the decorative plate 2 is flattened. Difficult to form.

When a paint such as a fluorescent ink is applied to the surface of a resin molded product having such a sink mark 5 (recessed portion) by using a conventional screen printing method, a large amount of paint enters the recessed portion 5 (the pool). The coating thickness of the paint becomes uneven. Particularly when the coating material is a fluorescent ink, the unevenness of the coating thickness causes uneven excitation luminance on the surface of the decorative plate 2, resulting in a problem that the quality of the decorative plate deteriorates. In order to solve this problem, a means of painting with a spray means is also adopted, but with this painting means of spraying, a large amount of paint is scattered, and the paint is an expensive fluorescent paint. In some cases, there is a problem that the economy is poor.

[Means for Solving the Problems] The present invention has been made by paying attention to such a conventional problem. Even if the conventional screen printing means is improved by improving the configuration of the screen used for the screen printing means. A coating film having a uniform thickness can be formed on the surface of an object to be coated. That is, the present invention is the development of a screen in which a large number of partitions are formed on the contact surface of the woven screen with the object to be coated to form dots with closely-spaced coating. By this, it is possible to apply a coating having a uniform thickness on the surface of the object to be coated having the depression.

[Embodiment] The present invention will be described in detail below with reference to an embodiment shown in FIGS. 1 and 2.

In FIG. 1, reference numeral 11 is a screen obtained by weaving a known material, and the screen 11 is tensioned and held by a base frame 12 on all four sides. A large number of partitions 14 extending directly below the screen 11 are formed on the lower surface of the screen 11, that is, the entire surface to be joined to the object to be coated 13. The process of creating the large number of partitions 14 is as follows. .

First, the lower surface of the screen 11 is coated with a range-type or diazo-type emulsion to form an emulsion layer having a thickness of about 10 μm.
Then, a negative having a predetermined dot pattern or the like is superposed on the surface of this emulsion layer, and the emulsion is exposed to light to form irregularities, that is, partitions 14 by a commonly used photomechanical process. The width of the partition 14 is preferably about 0.3 to 1 mm, and the inner diameter of the space surrounded by the partition 14 is 1 mm.
It is desirable to be ~ 3 mm.

Since the screen 11 configured in this way has a large number of partitions 14 on its lower surface,
Ink, for example, fluorescent ink 15 from the top surface of squeegee 16
When printing with, the fluorescent ink 15 fed to the lower side of the screen 11 is pushed into each space partitioned by each partition 14. Since each space is formed in a space of approximately the same volume, the amount of fluorescent ink 15 that has entered each space is approximately the same. In addition, since the fluorescent ink 15 once entering each space is stopped in each space by each partition 14 without moving in the other space direction, the screen 11 shown in FIG.
As shown in FIG. 5, the dot-shaped coating ink 15 'having substantially the same size is transferred onto the surface of the object to be coated.

As described above, according to this embodiment, since a large number of partitions 14 are formed on the lower surface of the screen 11 to form a large number of closely-spaced spaces at equal intervals, each partition is printed at the time of printing the ink by the squeegee 16. A substantially fixed amount of ink is pushed and positioned in each space defined by 14, and the ink in each space is directly transferred to the surface of the object to be coated 13 (first
As shown in FIG. 3C, the surface of the article 13 to be coated is coated with the ink 15 'with a uniform coating thickness.

In addition, in the dot-shaped coating ink 15 ′ coated on the surface of the object 13 to be coated by the screen 11, the dot shape is circular as shown in FIGS. 2A, 2 </ b> B and 2 </ b> C. , A hexagon, a quadrangle, or the like can be set as appropriate. Since the size of each dot is determined corresponding to the inner diameter of the space, a dot pattern with a diameter of 1 to 3 mm, for example, the circle shown in FIG. 2 (a) has a diameter of about 1 mm. 2 (b) has a maximum diagonal width of about 1.5 mm, and the rectangle shown in FIG. 2 (c) is a rectangle having a short side of about 0.3 mm and a long side of about 1 mm.

As described above, in this embodiment, since a large number of spaces partitioned by the partition 14 are formed on the lower surface of the screen 11, that is, the contact surface with the object to be coated, at close intervals, the rear surface (lower surface) of the screen 11 ), The coating amount of the paint located between the back surface and the object to be coated is regulated by the volume of the above space, and therefore the coating surface of the object to be coated with unevenness (dent) has a uniform thickness. Fluorescent ink is applied with a coating thickness so that unevenness in excitation light emission does not occur.

[Advantages of the Invention] As described above, according to the present invention, in a decorative plate in which a printed layer of fluorescent ink that emits light in response to light from an ultraviolet lamp is formed on the surface of a resin-formed molded plate, the printed layer is small. Since it is a black light illumination decorative plate that is divided into sections and printed and has a uniform layer thickness, according to this, the fluorescent ink amount of each section divided and printed into sections is uniform, and therefore uneven Veneer that is a resin product that easily causes
Since the fluorescent ink is applied to the surface of 13 with a uniform application thickness, the effect that unevenness in excited emission luminance does not occur can be obtained.
