Description

[Detailed Description of the Invention] This invention relates to a stained decorative board, particularly a decorative board formed for use with stained gas by applying colored coating to a synthetic resin board.

The purpose of this invention is not only to make it possible to easily produce a wide variety of designs, patterns, and colors using drawing or painting methods without the need for special equipment, but also to create a stained-like appearance. It is possible to achieve good clarity of the boundary line between the border line and the adjacent translucent colored area, which is an important element for expressing the appearance of the product, and it also has excellent durability and weather resistance. An object of the present invention is to provide a stained decorative board made of synthetic resin.

Therefore, the stained decorative board according to this invention is
As in the illustrated embodiment, a boundary line 2 of a desired pattern, design, etc. is formed on one side of a transparent synthetic resin substrate 1 with synthetic resin ink using a ketone solvent, and this boundary line 2 On the board surface of the part excluding
A colored coating layer 3 containing at least a translucent layer made of synthetic resin ink using an alcohol solvent;
3', 3''... are formed.

The synthetic resin substrate 1 is generally made of, for example, vinyl chloride resin or acrylic resin, and is transparent and colorless, but it may be colored and transparent if necessary. Further, in order to enhance the decorative effect, it is effective to use a patterned plate having a concavo-convex surface 4 on one side as shown in the figure.

The boundary drawing line 2 is mainly an outline drawn in correspondence with a desired design, pattern, etc., and therefore is not necessarily continuous, but may also be formed in the form of dots or broken lines. It can be done. The ink forming this border line needs to be made of a synthetic resin based in particular a ketone solvent. That is, since the ink made from the ketone solvent has relatively low fluidity, it is suitable for painting in a raised state as shown in FIG. Because it is not compatible with other inks, it helps to make those boundaries clearly visible. The ink can be a known ink that is usually used as an ink for screen printing, in which a vehicle made of an acrylic resin or a vinyl chloride resin is dissolved in a ketone solvent together with a coloring agent. A mixture of about 10 parts by weight of a ketone solvent based on 100 parts by weight of the ink can be suitably used. In addition, the border line 2 does not necessarily need to be transparent; rather, in order to clearly emphasize it, it is necessary to form it in an opaque state using a dark color ink similar to black, especially if it is not black. is common.

The transparent colored coating layers 3, 3', 3''... are formed using a synthetic resin ink using an alcohol solvent that is incompatible with the boundary line 2. The reason why solvent-based ink is used is not only because it is insoluble with the ink that forms the boundary drawing line 2, but also because it has high fluidity and is therefore suitable for brush painting and brush painting on large areas. The ink is based on the fact that it can be easily carried out, and unlike inks using ketone solvents, it does not attack the synthetic resin plate 1, and therefore it can provide good translucent coloring. It is possible to use an alcoholic solvent mixed with a coloring agent such as vinyl chloride resin or acrylic resin as a vehicle, which is commonly used for screen printing, gravure printing, etc. For example, commercially available printing ink 100 Part by weight of alcohol solvent
A diluted product of 200 parts by weight or more can be preferably used.
Colored coating layers 3, 3' formed by this ink,
3'' is mostly formed of translucent material in order to produce a desirable stained decorative effect, but if necessary, it may be formed with partially opaque material. As an example, generally, a plurality of colored objects having different colors are arranged in an appropriate arrangement across the boundary drawing line 2.

In the illustrated embodiment, the boundary line 2 is formed in a raised state that protrudes from the colored coating layers 3, 3', 3'', but this is not necessarily a requirement; It may be formed in the form of a thin film so that the level is approximately the same as that of .

As mentioned above, this invention requires special industrial production because it forms a stained-like appearance by forming boundary lines and a colored coating layer on one side of a synthetic resin substrate using painting or drawing means. Not only can it be easily manufactured without requiring any equipment, but it can also be easily produced by freely drawing boundary lines and colored layers and selecting colors.
Decorative plates with a wide variety of different designs can be manufactured according to preference, and a wide variety of decorative plates can be easily provided. In addition, due to the use of relatively different solvent inks for the boundary line and the colored coating layer, the boundary line appears blurred due to compatibility between the two inks, as would be the case if inks of the same composition were used for them. It can express clear and sharp border lines without any blemishes, and can produce an excellent stained effect.
In addition, since a solvent-based synthetic resin ink containing a ketone solvent is used as the ink for the boundary lines, the solvent acts to soak the surface of the substrate when it is applied to the substrate, causing the ink to soak up the surface of the substrate. In addition to increasing the adhesion, the solvent-based synthetic resin vehicle itself has excellent adhesion to substrates such as vinyl chloride and acrylic resin, and this combined with the fact that the adhesion of the boundary line to the substrate is extremely good. This makes it possible to improve the durability and weather resistance of decorative boards.
In addition, the above ink using a ketone solvent dries quickly, making it easy to form a boundary line, and immediately after forming the ink, the inner colored layer can be formed without any hindrance. The decorative board can be manufactured efficiently. Furthermore, by using a synthetic resin ink with an alcohol solvent as the ink for the colored coating layer, the solvent slightly soaks the substrate and improves adhesion, but it is not as strong as ketone solvents, so it improves translucency. In the colored coating layer part, it is possible to maintain good smoothness of the substrate surface and form a colored part with good translucency, which in turn makes it possible to produce and provide beautiful stained decorative boards with excellent luminous effects. It has the effect of
