Description

[Detailed Description of the Invention] The present invention relates to a laminate, and more particularly to a laminate that uses an A-tone thin film but exhibits an A-tone metallic luster rather than an A-tone metallic luster. be.

A thin film has traditionally been used in many cases to impart a metallic luster to laminates, but depending on the purpose and application, the A gloss is not enough, and the unique heavy white silver luster of the A finish is used. A is used to obtain .

However, A inherently has a fatal flaw in that it reacts very easily with sulfur and sulfides to produce yellow to black silver sulfide, resulting in discoloration.

In addition, as a type of precious metal, it is very expensive, and in this era of resource conservation, energy conservation, and conservation, using A metal is a considerable economic loss compared to using A metal. be. The present invention eliminates the above-mentioned drawbacks, and provides a laminate that exhibits an elegant A-tone metallic luster while using A finish, which is free from discoloration due to sulfurization, is inexpensive, and is easy to handle.

This invention comprises at least a sheet-like carrier, an AI thin film, a pale white coating layer containing a white pigment, plastic beads, or fine glass beads, a coloring material, and a crab light dye having the same color as the coloring material. A laminate comprising a colored layer containing at least the pale white paint layer, which is located between the A thin film and the colored layer, and when viewed from the colored layer side. In this case, the laminate is characterized in that the colored layer, the pale white paint layer, and the A-lined thin film together exhibit an A-tone metallic luster.

The present invention will be explained below with reference to the drawings.

This invention comprises at least a sheet-like carrier 1, an AI thin film 2, a pale white coating layer 3 containing a white pigment, plastic beads, or fine glass beads, a coloring material, and a colorant of the same color as the coloring material. A colored layer 4 containing a halo dye is provided. The sheet-like carrier 1 is a film made of polyester, polypropylene, vinyl chloride, polyethylene, and other various plastics, cellophane, paper, metal foil, glass, and other possible carriers, and composites thereof. The sheet-like carrier 1 may be one whose surface has been appropriately treated. The A-thin film 2 is an A-thin film or an A-thin foil obtained by vacuum evaporation, sputtering, ion plating, or any other suitable thin film production method.

The film 2 may have a thickness as long as it exhibits that metallic luster, and is approximately 100A or more in thickness. Incidentally, when an A foil is used as the A foil thin film 2, the A foil can also serve as the sheet-like carrier 1. The pale white coating layer 3 contains white pigment, plastic beads, or fine glass beads.

The white pigment, plastic beads, or fine glass beads give it a visually pale white appearance. The colored layer 4 contains a coloring material and a crab light dye having the same color as the coloring material.

Light-receiving dyes include not only so-called crab light dyes but also crab light brighteners. As the coloring material, transparent and porous dyes are preferred. If the coloring material is yellow, for example, the crab light dye is a yellow crab light dye. This invention is thus:
At least a sheet-like carrier 1, a thin film 2, a pale white coating layer 3 containing white pigment, plastic beads, or fine glass beads, a coloring material, and a crab-light dye having the same color as the coloring material. The coloring layer 4 includes a colored layer 4 containing .

Therefore, in addition to these materials, it is free to bond other materials, provide a protective layer, or form an appropriate layer. Furthermore, two or more of the laminates of the present invention illustrated in FIGS. 1 to 4 can be combined together. Alternatively, a thin film 2, a pale white coating layer 3, and a colored layer 4 may be provided on both sides of the carrier sheet 1, respectively.
In this invention, at least the pale white coating layer 3 is located between the A-lined thin film 2 and the colored layer 4. As long as these conditions are met, the sheet-shaped carrier 1 may be positioned anywhere; for example, as shown in FIG. 1 or 4, the sheet-shaped carrier 1 may be the outermost layer, Further, as shown in FIG. 2 or 3, a sheet-like carrier 1
may be the inner layer. When viewed from the colored layer 4 side, this invention shows the colored layer 4, the pale white paint layer 3, and the A thin film 2.
Together they give an A-tone metallic luster. That is, the thin film 2 is passed through a pale white coating layer 3 containing a white pigment, plastic beads, or fine glass beads, and a colored layer 4 containing a coloring material and a crab light dye of the same color as the coloring material. When viewed in this way, the A-fin film appears to have an A-tone metallic luster rather than an A-tone metallic luster. Therefore, as illustrated in FIGS. 2 to 4, when the A-line thin film 2 is viewed from the colored layer 4 side, if there is a sheet-shaped carrier 1 or the like in front of the AI thin film 2, The sheet-like carrier 1 and the like must be transparent or translucent. The A-thin film has a deep and elegant white silvery luster, while the A-thin film originally has a dark metallic luster. Therefore, in order to obtain a solid and rough white silver glow like A-thin film even though it is A-thin film, it is necessary to give whiteness to A-thin film on the one hand, and to create a profound and elegant taste on the other hand. I have to let it happen.
The pale white coating layer 3 of the present invention changes the blackish metallic luster of the A thin film to a whitish metallic luster by the white pigment, plastic beads, or fine glass beads contained therein. By scattering a portion of the incident light and the reflected light from the A-thin film, the effect of the light beam on the metallic luster depending on the viewing angle is eliminated, and the A-thin film has a whitish metallic luster similar to the A-thin film when viewed from any angle. That is.

The colored layer 4 of the present invention exhibits a desired color due to the coloring material contained therein, and the crab light dye of the same color as the coloring material contained therein is exposed to incident light as well as a thin film and a pale white color. It is excited by the reflected light and scattered light from the coating layer, and the color of the crab light dye becomes subtle, giving the A-Yu thin film a deep and elegant metallic luster like the A-Yu thin film.

As described above, the present invention includes the A-line thin film 2, the pale white coating layer 3 containing white pigment, plastic beads, or fine glass beads, and the coloring material and the honeydew dye having the same color as the coloring material. Only when the colored layer 4 is integrated with the colored layer 4 does it exhibit a deep and elegant A-tone metallic luster.

Example 1 One side of a transparent polyester film (Diafoil manufactured by Diafoil) with a thickness of 25 mm was coated with A-coated film under a vacuum of 2×10 14 tons to form an A-coated film.

Next, a paint having the following composition was gravure coated on the A-deposited film using a 200 mesh roll to give a coating of 170q0.4.
Gravure coating was applied on the pale white coating layer using a 150-mesh roll with the following composition, and the coating was coated and dried under the conditions of 180 pm and 60 seconds. A colored layer was formed. As described above, a heavy and elegant laminate having a yellow colored A-tone metallic luster was obtained.

Example 2 A grain deposited film was formed on one side of the transparent polyester film used in Example 1 in the same manner as in Example 1, and A
A protective layer of alkyd resin was provided on the deposited film.

Next, a pale white coating layer was formed on the film side of the A-deposited film obtained in this way in the same manner as in Example 1,
Further, on the pale white paint layer, a paint having the following composition was gravure coated using a 160 mesh roll.
○, 6 A colored layer was formed by drying and drying under the conditions of rat sand.

As described above, a thick and elegant laminate having a pink colored A-tone metallic luster was obtained.

This invention can be used as it is, or printed, colored, coated, or laminated with other materials. Transfer materials, building materials, insulation materials,
It can be widely used in light-shielding materials, molding materials, labels, agriculture, and various other applications in which laminates with metallic luster have traditionally been used.

This invention is a laminate that exhibits the metallic luster of A-yellow, rather than the metallic luster of A-yellow, even though A-yellow is used.

However, this invention is not limited to laminates, but can be widely applied as a method for imparting gloss to A-coats. That is, if A is viewed through the pale white coating layer and colored layer of the present invention, regardless of whether it is in the form of a lump, a thin film, or any other form, A
It has a multitonal, profound, and elegant metallic luster. Although this invention is relatively similar to A,
By using A steel, which has a luster that is clearly different from A steel, it brings out the profound and elegant metallic luster of A steel.

However, in addition to A, there are many other metals that are relatively similar to A and have luster distinctly different from A and A. Examples of these metals include Al alloy, Ni
, Cr, NjCr, ln, Fe, NiFe, Pd, Pt
, Sn, Ti, Ti alloy, Zn, etc. Regarding these metals, regardless of whether they are in the form of lumps, thin films, or other forms,
It is possible to obtain a g-tone metallic luster.
