[Conventional technology and problems]

Conventionally, the so-called hot stamping method has been widely used in order to impart aesthetics and decorativeness to products. This method is a printing technology by transfer, but unlike the wet method like general printing, it is a dry method, so there is no risk of health problems or explosions due to ink stains or the use of organic solvents, etc. It also has the advantage that no drying process is required.

The basic structure of hot stamping (foil) is the third
As shown in the figure, the substrate (film or paper) layer (1), the undercoat layer (2), the silicone release agent layer (3), the coloring layer (4), the aluminum vapor deposition layer (5), and the adhesive layer. It consists of (6). However, in the above-mentioned conventional method, since the release agent layer is made of a silicon coating layer, the thickness is thin, and therefore a three-dimensional pattern cannot be provided, and a decorative property having a three-dimensional pattern or perspective pattern is provided. Is impossible. Further, the silicone coating is not only complicated in work, but also requires the use of a solvent, resulting in a loss of the advantages of the hot stamping method even though it is basically a dry printing method. Has become.

[Means for solving problems]

In view of such circumstances, the present invention provides a transfer laminate and a method for manufacturing the same, which solves the above problems.

That is, the first aspect of the present invention is to provide a transfer laminate comprising a base material and a surface provided with a three-dimensional pattern on the surface of the release resin layer opposite to the three-dimensional pattern surface. Second, the release resin is melt-extruded on the surface of the base material, and the surface state of the cooling roll in contact with the surface of the release resin opposite to the base material is changed to mat, semi-mat, hairline, mirror, etc. According to the third aspect of the present invention, there is provided a method for producing a transfer laminate, characterized in that the respective patterns are formed on the surface of the releasable resin between the base material and the sheet having a three-dimensional pattern. Characterized in that a release resin is extruded, the three-dimensional pattern of the sheet is transferred onto the surface of the release resin, then cooled, and then the sheet having the three-dimensional pattern is peeled and separated from the surface of the release resin. According to a fourth aspect of the present invention, there is provided a substrate, A releasing resin is extruded between the printing sheet and a printing sheet on which a predetermined three-dimensional pattern is printed, the three-dimensional pattern of the printing sheet is transferred to the surface of the releasing resin, and then cooled, and then the printing sheet is released. A method for manufacturing a transfer laminated material, which comprises separating and separating from the surface of a resin,
Each is a content.

The substrate used in the present invention is not particularly limited as long as it has heat resistance enough to withstand the temperature at the time of transferring to a transfer material, and for example, paper, cloth, polyethylene terephthalate (PET), polybutylene terephthalate (PB
T) etc. polyester, polyamide, polycarbonate, polyacetal, polyimide, polysulfone, polyethersulfone, polyetheretherketone,
Synthetic resin sheet (film) such as poly 4-methylpentene-1 (TPX) and polypropylene, metal foil, laminating metal foil and synthetic resin sheet (film), laminating paper and synthetic resin sheet (film), cloth And a synthetic resin sheet (film). In particular, biaxially stretched polyethylene terephthalate film is suitable.

The releasable resin used in the present invention has appropriate releasability and holding power, has sufficient thermoplasticity for good patterning when transferring a three-dimensional pattern, and has a coloring property. And / or any material having good vapor deposition property, for example, having releasability such as poly-4-methylpentene-1 (TPX), polypropylene, ethylene-propylene copolymer, ethylene / vinyl alcohol copolymer and the like. A thermoplastic resin and a mixture obtained by adding an additive for imparting releasability to these are preferably used. Especially polypropylene, poly 4-
Methylpentene-1 and a mixture thereof are preferable because they have appropriate mold releasability and holding power. The thickness of the releasable resin layer is not particularly limited, but may be about 10 to 30 μm. The release resin layer can be formed on the base material by a hot melt method or the like, but the extrusion method is particularly preferable from the viewpoint of productivity and work efficiency.

One of the features of the present invention is that the releasing resin layer is provided with a three-dimensional pattern. Therefore, the transfer material is provided with a three-dimensional pattern or a perspective pattern to realize a three-dimensional solid design and decoration. Not only that, if a colored layer and a vapor-deposited layer are further provided, the two interact to realize a unique design and decoration that is three-dimensional and rich in glossiness and directionality.

The three-dimensional pattern in the present invention is not particularly limited, such as a pattern, a character, a character, a symbol, a hairline, a matte tone, and an unevenness for imparting a semi-matte tone. Further, a method of giving a three-dimensional pattern to the releasable resin layer may be a conventionally known method. For example, the releasing resin surface of the laminated material of the present invention may be appropriately preheated, passed between pressure rolls, pressed by a pressure press, or the like. A three-dimensional pattern can be imparted to the releasable resin layer simultaneously with the lamination with the releasable resin layer, which is extremely advantageous.

One of the preferred methods by extrusion is one in which the substrate is
The so-called sandwich laminating method in which a sheet having a three-dimensional pattern is fed from the other side and a release resin is extruded between the two is most suitable. Of course, a method in which a release resin is first extruded on a base material to form a molten resin layer, and then the sheets are laminated to transfer a three-dimensional pattern to the molten resin layer can be suitably used. In any case, by peeling and separating the sheet after cooling, a transfer laminate in which the three-dimensional pattern of the sheet is transferred to the releasable resin surface can be obtained. The sheet having the three-dimensional pattern can be easily obtained, for example, by using a die roll. As such an embossed sheet, it withstands the temperature during embossing with a die roll,
And there is no particular limitation as long as it is a synthetic resin having heat resistance to withstand the temperature at which the embossed three-dimensional pattern is transferred to the release resin layer, for example, PET, polyester such as PBT,
Sheet (or film) of polyvinyl chloride, polyamide, polycarbonate, polyacetal, polypropylene
Further, a composite material in which these and a backer material (for example, laminated with paper) are attached to each other can be given.

The method of using the three-dimensional pattern sheet, since it is sufficient to prepare a sheet having a three-dimensional pattern instead of the mold roll, large weight, it is not necessary to stock a large number of mold rolls,
Equipment costs are drastically reduced.

Another preferable method by the extrusion method is a method of using a printing sheet in which a predetermined three-dimensional pattern is printed on a synthetic resin sheet. That is, a printing sheet on which a predetermined three-dimensional pattern is printed on the base material from the other is fed from one side, a release resin is extruded between the two, and after the three-dimensional pattern of the printing sheet is transferred to the release resin layer, By peeling off after cooling, a transfer laminate having a three-dimensional pattern transferred can be obtained. The same synthetic resin as the sheet having the above-mentioned three-dimensional pattern can be used as the printing sheet, and the printing layer can be a powdery material such as ink, pigment, etc., which can be used for printing metal powder, ceramic powder, metal oxide, etc. Body, the amount and color of the granules are appropriately combined, that is, the particle diameter, shape, dispersity, etc. of these are changed, and the glossiness at various stages is changed by a known printing method,
The three-dimensional pattern is formed by combining it with a tone, and in addition to the pattern, there is no particular limitation such as patterns, characters, characters, symbols, and surface irregularities for giving a matte tone.

The method of using this printing sheet provides a microscopic and delicate three-dimensional effect and perspective compared to the case of using the above-described embossing three-dimensional pattern sheet, and is remarkably versatile.

Examples of the sheet having a three-dimensional pattern include paper (particularly Japanese paper), non-woven fabric, woven fabric, in addition to the above embossed sheet and printed sheet.
A laminated board (natural wood grain thin board), a flocked sheet, and a composite sheet obtained by laminating these with a backer material can be used.

Furthermore, in the case of the extrusion method, by changing the surface condition of the cooling roll to a mat, a semi-mat, a hairline, a mirror, etc., each three-dimensional pattern is transferred and formed on the surface of the release resin, and the transferred three-dimensional pattern is formed. Mode and holding power,
The releasability can be freely adjusted or changed.

As described above, when a colored layer and / or a vapor deposition layer is provided on the release resin layer having a three-dimensional pattern, a known method may be used. Further, a known adhesive may be used as the adhesive used for transferring the material to be transferred.
