DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a glittering sheet. More specifically, the present invention relates to a glittering sheet having excellent glittering properties, decorative properties and durability.

[Conventional technology]

BACKGROUND ART Conventionally, a heat-shielding glittering sheet obtained by applying a polymer resin coating material containing a glittering substance powder such as aluminum powder onto one surface of a base fabric made of a fiber cloth is known. However, in such a conventional glittering sheet, the hue thereof is limited to gray to silver and the content of the glittering substance powder is also 3 to 5%, so that the glossiness of the glittering is high. And the decorativeness was insufficient.

Therefore, it has been desired to develop a glittering sheet that can broaden the range of glittering colors and is excellent in its sharpness and decorativeness.

[Problems to be solved by the invention]

The present invention is intended to expand the brightness and color range of a glittering sheet to further improve its sharpness and decorativeness.

[Means and Actions for Solving Problems]

The glittering sheet of the present invention comprises a base fabric made of a fiber cloth and a glitter coating layer formed on at least one surface of the fabric, wherein the glitter coating layer comprises (1) a flexible layer. A brilliant particle layer comprising a matrix composed of a united resin and particles of a brilliant substance dispersed in the matrix, and (2) a flexible transparent polymer formed on the brilliant particle layer. And a coating surface layer made of a resin.

Further, another glittering sheet of the present invention comprises: a base cloth made of a fiber cloth, a base cloth coating layer formed on at least one surface of the base cloth and containing a flexible polymer resin as a main component, A bright coating layer formed on at least one of the base cloth coating layers, wherein the bright coating layer is (1) a matrix made of a flexible polymer resin and dispersed in the matrix. A bright particle layer containing particles of a bright substance, and (2) a coating surface layer formed on the bright particle layer and made of a flexible transparent polymer resin. To do.

In the glittering sheet of the present invention, the glittering particle layer containing the glittering material particles is protected by the transparent coating surface layer that coats the glittering material particles. It is protected from deterioration such as oxidation and hydrolysis, and also protected from physical effects such as scratching and abrasion. Therefore, the content of the glittering substance particles in the glittering particle layer can be increased to 10 to 60% by weight. Further, by arranging the base cloth coating layer between the base cloth and the glitter particle layer, it has become possible to further increase the light brightness of the glitter particle layer.

The base fabric used in the glittering sheet of the present invention is made of a fiber cloth and improves the mechanical strength, dimensional stability and durability of the glittering sheet.

The fiber cloth used for the base cloth is a knitted woven fabric, a non-woven fabric, or
Although any of these composite materials can be used, in general,
It is preferably a woven fabric. The fibers constituting the fiber cloth may be any of natural fibers, synthetic fibers, inorganic fibers, regenerated fibers, semi-synthetic fibers, etc., but generally polyester fibers, polyamide fibers, water-insolubilized or sparingly-solubilized polyvinyl alcohol. It is preferably selected from fibers and the like, and when the glittering sheet is required to have high strength, high heat resistance, etc., the fabric constituting the base fabric may be composed of aromatic polyamide fibers or may contain the same. preferable.

The fibers constituting the fiber cloth may have any shape such as spun yarn, multifilament yarn, monofilament yarn, tape yarn, split yarn and the like.

There is no particular limitation on the organization or basis weight of the base cloth, but generally 50

It is preferably not less than 10% by weight but preferably in the range of 10 to 60% by weight. The content of the glittering substance particles in the glittering particle layer is
When it is less than 10% by weight, the glitter obtained is insufficient and the appearance becomes close to gray. However, if it is more than 60% by weight, the mechanical strength of the glitter particle layer may be lowered, and the adhesive strength between the glitter particle layer and a layer adjacent thereto may be lowered.

The matrix composed of the flexible polymer resin in the glitter particle layer binds the glitter material particles, and generally,
Synthetic resins such as polyvinyl chloride resin, polyethylene resin, polypropylene resin, polyamide resin, polyester resin, polyacrylic resin, ethylene-vinyl acetate copolymer resin, polyurethane resin, silicone resin, fluorine-containing polymer resin, and vinyl chloride- Vinyl acetate copolymer resin or the like, or natural and synthetic rubbers such as neoprene, hypalon, polynitrile rubber, SBR, polyisobutylene, butyl rubber, polybutadiene rubber, EPT,

The thickness of the glitter particle layer is not particularly limited, but in general, when the glitter particle layer is formed on the base fabric coating layer described later, it is preferably 1 to 50 μm, and 3 to 30 μm. Is even more preferable. When the glitter particle layer is directly formed on the base cloth, it may have a thickness of 0.1 to 1.0 mm. In this case, it is preferable to use a transparent resin because the matrix resin layer is thick.

The matrix in the glitter particle layer may be transparent, but may be colored in any hue and darkness, which can enhance the decorative property of the glitter sheet.

The bright particle layer can be formed by a known method such as a coating method in which a coating material containing a desired component is applied and solidified, a gravure method, or a laminating method in which films containing the desired component are laminated and adhered.

The covering surface layer may be transparently colored in any hue and concentration as long as it does not impair the luster of the entire laminated sheet, whereby the desired decorative property can be imparted to the entire laminated sheet.

The coated surface layer can be formed by the known coating method, gravure method, laminating method and the like as described above.

Further, when the coating surface layer is formed of a polyacrylic resin or a fluorine-containing polymer resin, it shows good antifouling property and weather resistance, and has a three-layer structure of polyvinyl chloride / polyacrylic / fluorine-containing polymer. It is also possible to use a transparent composite film having

Contained rubber, silicone rubber, etc.) and synthetic resins (for example, polyvinyl chloride resin, polyethylene resin, polypropylene resin, polyamide resin, polyester resin, polyacrylic resin, polyurethane resin, silicone resin, fluorine-containing polymer resin, ethylene-vinyl acetate) (Copolymer resin, vinyl chloride-vinyl acetate copolymer resin, etc.).

This base cloth coating layer imparts waterproofness to the base cloth, improves the adhesive strength between the base cloth and the glitter coating layer, and forms the back of the glitter particle layer to provide the glitter or decorative property. Can be increased. For example, the base cloth coating layer can be made white and opaque, but in this case, it is effective in promoting the glitter effect of the glitter particle layer. Further, the base cloth coating layer can be colored and opaque, but in this case, the glittering sheet is
It is effective in promoting decorativeness and glitter when used as a tent film body. Further, when considering the light-collecting property of the film body, it is preferable that the base cloth coating layer is transparent or semi-transparent.

When the base cloth coating layer is formed on both sides of the base cloth, both layers may be colored, and the coloring may be performed between the both layers in mutually different hues and / or concentrations. . For example, if the base fabric coating layer under the glitter coating layer is made white opaque, and the exposed base fabric coating layer on the opposite side is colored in an arbitrary color, the glitter and decorative properties of the entire glitter sheet are enhanced. be able to. Further, at least one of the coating surface layer, the bright coating layer and the base fabric coating layer may be colored according to a desired pattern to form a pattern.

The base cloth coating layer can be formed by a known coating method, dipping method, calendering method or laminating method.
