BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer foil capable of easily transferring a pattern having a high-brightness reflecting function to clothes, shoes, bags and the like as desired.

[0002]

2. Description of the Related Art It has long been practiced to form a retroreflective coating film on a traffic sign, clothes, etc. using a coating material using transparent glass beads. However, in such a paint, it is difficult to obtain a retroreflective coating film with good performance because the glass beads are used in a state of being integrated with the paint, and the coating film is formed into a delicate pattern. It was also difficult.

Therefore, it has been practiced to provide a layer having a highly bright reflecting function using glass beads on a sheet, cut the laminated sheet, and stick or sew it on a cloth or the like for use. In this method, since the laminated sheet becomes thick, there are limits to the designs that can be expressed, and a product with a good texture could not be obtained.

[0004]

Therefore, it is conceivable to form a transfer foil using glass beads and provide a transfer foil capable of transferring a pattern having a highly bright reflection function by a stamping method or the like. In order to form a bead layer stably, it is necessary to use a relatively thick substrate,
Further, in order to obtain good reflection, it is necessary to uniformly form a thin metal layer along the contour of the glass beads, so that a conventional transfer foil manufacturing method cannot obtain a practical one. It was

The present invention solves the above problems of the prior art, and uses glass beads to provide a transfer foil having a thin layer and excellent in high-brightness reflecting function, which can be used also as a stamping foil. The challenge is to provide.

SUMMARY OF THE INVENTION In the present invention, the above-mentioned problems are solved by forming a transfer foil having high-glossy reflection on a base film in a peelable state.

That is, in the transfer foil of the present invention, glass beads are embedded in a single layer on the metal thin film layer via the resin thin film, and the thermoplastic resin layer, the adhesive layer and the surface are separated on the glass beads. It is composed of a laminate in which films having mold surfaces are sequentially laminated and the total thickness is 70 to 200 μm.

Although it is difficult to directly produce such a laminate, in the present invention, by laminating the laminate on a thick base material film via an adhesive layer, it is possible to easily stabilize the laminate. It was possible to manufacture.

As described above, the transfer foil of the present invention has a thickness of 70.
Although it is possible to transfer a laminate having a thickness of up to 200 μm, it has hitherto been impossible to predict that a transfer pattern excellent in a high-brightness reflection function can be formed with such a thin layer by using glass beads. In the present invention, the above laminate,
As described above, by forming it on the base material film in a peelable state, it is possible to stably and efficiently use glass beads on textiles, metal, wood, paper, resin molded products, etc. This made it possible to form a good transfer pattern.

The product of the present invention is prepared by preparing a laminated film in which a pressure-sensitive adhesive layer is formed on a base film and a thermoplastic resin layer is provided on a film having a releasable surface via an adhesive layer. , The release surface of the laminated film is laminated on the pressure-sensitive adhesive layer, and then glass beads are embedded by thermocompression on the thermoplastic resin layer exposed on the surface, and then the glass bead surface exposed as a single layer ( Form a resin thin film on the curved surface,
It can be easily obtained by preventing the glass beads from falling off and depositing a metal such as aluminum on the glass beads.

In such a product, an adhesive made of a thermoplastic resin is printed in a desired pattern on the surface of an object to be transferred, and the surface of the metal thin film layer of the laminate (peeled from the adhesive layer) is placed thereon. By applying heat and pressure, a foil-like material having a high-brightness reflecting function, which is composed of the metal thin film layer / resin thin film / glass beads of the laminate, is transferred only to the part where the adhesive is present, and the remaining part is made of glass. It can be removed together with the thermoplastic resin layer \ adhesive layer \ film on the beads. Therefore, in the present invention, any pattern can be reproduced very efficiently and accurately as a transfer pattern having a high-brightness reflection function.

The transfer adhesive may be printed on the transfer foil of the present invention, that is, on the metal thin film layer of the laminate.

The type and thickness of the base film and the pressure-sensitive adhesive are not particularly limited, but as a film having a release surface, a thin film (thickness 16 to 16) having a release agent such as a silicon layer on the surface is used. 38 μm) is preferably used, and the thermoplastic resin layer laminated via an adhesive layer may be any that can be embedded by adhering glass beads by heating and pressurization, and is a general thermoplastic resin. Can be used, but the thickness thereof is about 1/3 to 2/3 of the diameter of the glass beads so that the glass beads can be embedded and attached with the curved surface partially exposed. preferable. Usually, it is preferable that the thickness is about 25 to 40 μm.

The adhesive layer for sticking the thermoplastic resin layer to the thin film may be selected according to the type of the thermoplastic resin layer.

It is preferable to use glass beads having a diameter of 40 to 100 μm, and the metal thin film layer formed on the surface of the glass beads through a resin thin film may have a thickness of about 600 to 800 Å. It may be formed by vapor deposition or the like.

The resin thin film may be formed by a reverse coater, a comma coater or the like to have a thickness of several μm. The resins used are acrylic, polyester,
It may be of a polyolefin type or the like.

The transfer foil of the present invention has a total thickness of 70 to 200 μm.
m, preferably 80 to 150 μm, but usually 50 to 100 as a substrate film.
Since a film having a thickness of about μm is used, the thickness with the base film and the pressure-sensitive adhesive layer held is 150 to 25
The thickness is about 0 μm.
