Description

[Detailed description of the invention] [Industrial field of application] This invention relates to stained glass made of resin.

Like conventional stained glass, it can be used for interiors expressing various designs and color patterns, decorative windows for exteriors, lighting equipment, etc.

[Conventional technology] Traditionally, stained glass was made of glass,
This glass material is colored by adding metal to it, and in order to express designs and patterns, the necessary amount of colored glass is cut out into the necessary shapes and assembled, and the manufacturing process is extremely complicated and difficult. Therefore, it is expensive, and it is difficult to increase the strength, and there is a desire to develop countermeasure technology for these points.

[Problem to be solved by the invention] This invention was made in view of the above circumstances, and provides a pseudo-stained glass that is easy to manufacture, mass-producible, inexpensive, and durable. The purpose is to

[Means for solving the problem] In response to this purpose, the resin stained glass of this invention is made by screen printing using UV ink on the inner surface of a transparent acrylic plate with a wrinkled pattern on the outer surface. Ink layers each having a single color are formed and arranged adjacent to each other, a coating layer that covers the ink layer and has a wrinkle pattern on the outer surface, and ink layers arranged adjacent to each other on the outer surface of the coating layer. It is characterized by having a pattern consisting of an ink layer for edging formed by screen printing using UV ink at a position corresponding to the boundary part of.

[Function] In the resin stained glass constructed in this way, each of the plurality of ink layers imitates the colored glass pieces of the real stained glass, and the edging ink layer imitates the colored glass pieces of the real stained glass. stained glass, so that the whole exhibits the same appearance and optical characteristics as real stained glass.

[Example] Hereinafter, details of this invention will be explained with reference to drawings showing an example.

In FIG. 1, reference numeral 1 denotes resin stained glass, in which an ink layer 3 is formed by printing to express a design or pattern on a substrate 2 made of transparent or colored resin.
A transparent resin coating layer 8 is placed on top of the ink layer 3 to cover the surface of the ink layer 3.

The ink forming ink layer 3 is UV ink,
Normal photopolymerizable prepolymers, photopolymerizable monomers,
It is made up of a photoinitiator, sensitizer, colorant, and other additives, and the amount of additives added is determined by taking into consideration the maintenance of the transparency of the ink.

Printing of the ink layer 3 is performed by screen printing.

The order of printing the ink layer 3 is, for example, first a layer 4a of color A for edging, then a layer 5 of color B, then a layer 6 of color C and a layer 7 of color D, and then a layer 4a of color A on top of that. layer 4b of
is printed in the same position above and below layer 4a. Here, the color A is, for example, black, the color B, or the color C, and the color D is, for example, yellow, green, or red.

However, the A color layer 4b for edging is the coating layer 8.
It may be provided inside the coating layer 8 on the boundary between layers 5 and 6, or it may be provided outside the coating layer 8 as shown. Of the two surfaces of the substrate 2, the printing surface 11
is flat, but a wrinkle pattern is formed on the other surface 12, making it a rough surface. Also, coating layer 8
The outer surface is also rough.

The printing order in FIG. 1 may be partially changed to be as shown in FIG. 2.

That is, in FIG. 2, a layer 4b of color A is formed on the coating layer 8, and a layer 4a of color A is printed on the other side 12 of the substrate 2. The method shown in Figure 2 is based on the substrate 2.
It is effective when the thickness of the plate is small;
In the method shown in FIG. 2 in which at least one of the A color layers 4a and 4b for edging is provided on the outermost side, the A color line for edging can be clearly seen.

The ink layer 3 on the substrate 2 is cured as required by an infrared device or an ultraviolet device each time each color is printed.

[Effect of the invention] Since the resin stained glass constructed in this way is composed of a single plate substrate 2, it has greater strength than conventional glass stained glass, and
Since the reflection by the wrinkle pattern formed on the surface 12 of the substrate 2 and the surface of the coating 8 reduces the transmission of ultraviolet rays, the light resistance of the ink layer 3 of the color ink is improved, and the vividness of the color can be maintained for a long time. Furthermore, by using UV ink, the ink layer 3 is resistant to cleaners and solvents, so it has excellent durability. These wrinkle patterns also increase the visual effect.

In addition, the formation of designs and patterns is possible through printing.
Since it can be done through a process, it is easy to manufacture, mass production is possible, and inexpensive stained glass can be obtained.
