BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vinyl floor material such as a vinyl tile used as an interior floor material for shops, houses, buildings and the like.

[0002]

2. Description of the Related Art Conventional flooring materials such as vinyl tiles are shown in FIG.
And a backing material 1 as a support material made of resin, rubber, fibers, or a composite material of these materials, which has a cross-sectional structure as shown in plywood, laminated wood, wood, etc.
It consists of a colored vinyl chloride layer 2 and a transparent vinyl chloride layer 4 on which a printed pattern layer 3 is printed.The pattern is printed (gravure method,
Gravure offset method, flexo method, letterpress method, screen printing method, offset printing method, etc.).

FIG. 4 shows a conventional method for improving the design of a tile flooring material by utilizing the metallic luster.
As shown in (a), using a pearl pigment such as mica powder or metal powder such as aluminum or brass in a printing ink vehicle, a pearl ink, a silver ink, a golden ink, or other metallic luster ink 3a, A method of painting and printing on the vinyl chloride layer 4 (vinyl chloride sheet) together with the printed pattern layer 3, as shown in FIG. 4 (b), produced by mixing a pearl pigment and a metal powder 4a in a colorless transparent vinyl chloride resin. A method of printing the printed pattern layer 3 on the vinyl chloride layer 4 (vinyl chloride sheet), as shown in FIG. 4 (c), by mixing the pearl pigment and the metal powder 4a into the colored vinyl chloride resin mixed with the coloring material 4b. On the produced vinyl chloride layer 4 (vinyl chloride sheet), printed pattern layer
There is a way to print 3.

[0004]

[Purpose of the Invention] In the above conventional method (FIG. 4 (a)), a vinyl chloride sheet is prepared by using a gloss ink 3a mixed with a large amount of pearl pigment or metal powder to increase the metallic gloss.
In the case of painting with the printed pattern layer 3 on 4, the gravure printing method, which is said to be able to obtain a relatively good thickness, has a printable thickness of about 0.005 mm. The limit is to obtain a film thickness of 0.01 mm.

Further, the gloss ink 3a, which has a relatively smaller cohesive force than the commonly used printing ink, is
Since this becomes a factor that reduces the laminating strength at the time of bonding with the colored vinyl chloride layer 2, the gloss ink 3a has a limit in film thickness, and a high metallic luster feeling cannot be obtained.

Further, in the above-mentioned conventional method (FIG. 4 (b)), the transparent vinyl chloride layer 4 is provided with a metallic luster on the entire surface, so that a pattern having a metallic luster is partially formed. If the pearl pigment and the metal powder 4a are mixed in a large amount to obtain a glossy feeling, the opaqueness of the vinyl chloride layer 4 increases and the printed pattern layer 3 becomes difficult to see.

Further, in the above-mentioned conventional method (FIG. 4 (c)), like the method, it is not possible to show a partial gloss feeling. Also, the opaqueness of the vinyl chloride layer 4 itself is increased by mixing the coloring material 4b, and the pearl pigment,
The luster due to the metal powder 4a is reduced. Therefore, if a large amount of pearl pigment and metal powder 4a are mixed in order to bring out a further glossy feeling, the lower printed pattern layer 3 becomes difficult to see.

Therefore, the present invention is a laminated flooring material using vinyl chloride, and when colorless and transparent or colored transparent vinyl chloride is used as the uppermost layer, a printed pattern layer of a layer lower than that is used. It is an object of the present invention to provide a flooring material that can obtain a sufficient metallic luster without impairing the color texture of the lower layer.

DETAILED DESCRIPTION OF THE INVENTION The present invention comprises a flooring backing material layer 1, a polyvinyl chloride layer 2 having an embossed depression 5 and a gloss toning agent 6 filled with pearl pigment, metal powder or the like in the depression 5.
A vinyl flooring material characterized in that a transparent polyvinyl chloride layer (4) having a desired printed pattern (3) is laminated in order.

The present invention will be described in detail with reference to the drawings. FIG. 1 is a side sectional view of a vinyl flooring material according to an embodiment of the present invention, which is a support material such as plywood having an appropriate thickness with a smooth surface, or a polyvinyl chloride resin board containing fibers such as woven cloth. A colorless and transparent, or colored and transparent, or colored and translucent or colored and opaque polyvinyl chloride layer 2 is superposed on and adhered to the above 1 by using an appropriate adhesive.

On the surface of the polyvinyl chloride layer 2, a concave portion 5 having a depth of 0.01 mm to 0.20 mm, for example, is formed in a desired pattern by pressing using a predetermined press die or by a heating and pressurizing method.
Is embossed. A pearl luster color material 6a using a transparent resin as a binder is applied to the entire surface of the vinyl layer 2 provided with the embossed recesses 5, and then the squeegee method is used.
The wiping method or the like is used to wipe off the coloring material 6a on the surface thereof, and the coloring material 6a is embedded in the recess 5 to form the gloss layer 6.

On the upper surface of the polyvinyl chloride layer 2, a transparent vinyl chloride layer 4 provided with a printed pattern layer 3 by a printing method is laminated and stuck with the pattern layer 3 inside. The total thickness after bonding is, for example, about 1.5 mm to 5 mm.

Although the glossiness can be increased by increasing the depth d of the embossed concave portion 5, the upper and lower limit of the depth is not limited to 0.01 to 0.20 mm, and the color material 6a can be used. Gloss layer 6 formed by filling the recesses 5
Even if the layer thickness is 0.01 mm or less as long as it can be observed from the transparent vinyl chloride layer 4 side with a sufficient glossiness,
It may be 20 mm or more. However, from the viewpoint of workability, it is suitable that the diameter is around 0.01 mm to 0.10 mm.

The recess 5 has various shapes such as a hairline emboss, a satin emboss, a V-cut emboss, a fine mesh emboss, a fine dot emboss, and a stripe emboss by setting various shapes of a die for embossing. Shaped embossing can be adopted. Further, for example, the width w of the one-unit embossed concave portion 5 can be set as appropriate, but it is suitable that the width w is not more than twice the depth d.

Also, in the present invention, the embossed recess 5
It is possible to appropriately adjust the pattern integration degree of the pattern. For example, as shown in FIG. 2, an area 5a having a high glossiness in which the intervals between the patterns of the embossed depressions 5 are embossed to a high integration density of, for example, 0.1 mm or less. By forming the area 5b having a low glossiness and embossed to a lower integration density, it is possible to impart the strength of the pearly luster and the metallic luster.

Due to the coarse density of such a pattern,
Gradation can be added to the glossiness expressed by the metallic glossy layer 6, and the glossiness can be expressed by various shades of gray, and the pearly glossiness of the floor material or the metallic glossiness can be partially emphasized. It is possible to give a variation in gloss to the flooring material by weakening or weakening it.

The uppermost vinyl chloride layer 4 may be a little colored, but it must be transparent. Further, between the support material 1 and the polyvinyl chloride layer 2, it is possible to appropriately combine and bond laminated materials.

[0018]

In the present invention, since the color material layer of the pearl pigment and the metal powder is embedded in the embossed recess, the color material layer having a glossy tone can be made thicker than before, and by this, the laminated structure of the floor material can be obtained. Pearl luster, without impairing the transparency of the whole body
Only the brightness of metallic luster can be enhanced.

[0019]

[Effects of the Invention] The present invention can strongly improve the pearly luster and metallic luster without impairing the transparency of the laminated resin material of the upper layer that constitutes the design and texture of the flooring material.
It is possible to partially apply such a strong glossy feeling in a pattern, and it is also possible to partially enhance or weaken the glossy feeling and freely adjust it. It is a flooring material with an unprecedented luster and is of practical value.

An embodiment of the present invention will be described below.
