Abstract

PROBLEM TO BE SOLVED: To transfer a slender design on a cloth having interstices, stitches of a protrusion and recess portion with good reproducibility, by embedding glass beads in a releasable resin thin film on a transparent resin film, and sequentially laminating a resin coating layer, a colored film and a hot-melt adhesive layer on the beads. SOLUTION: A releasable resin thin film 2 is arranged on a transparent resin film 1, glass beads 3 are hot pressed thereon and embedded in a single layer state. A thermoplastic resin coating layer 4 is formed on the beads 3 by a gravure coater. A photograph desired to be a transfer design is color copied on the layer 4 to form a colored pattern 5. Further, the pattern 5 is screen coated with a resin liquid obtained by mixing nylon resin powder functioned as a hot-melt adhesive with a polyurethane resin solution to form a hot-melt adhesive layer 6. This transfer foil is brought into contact with a shell knitted woven fabric having a protrusion and recess part on its surface and hot pressed, and the pattern 5 is transferred to the cloth.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

TECHNICAL FIELD The present invention relates to a transfer foil using glass beads.

[0002]

2. Description of the Related Art Hitherto, various transfer foils for transferring a pattern to clothes or the like have been known. However, it was not possible to transfer a fine and delicate pattern on a fabric having irregularities in the weave or stitch. Further, a transfer foil using glass beads is also known, but this is for providing a retroreflective layer on a flat plate or the like, regardless of a fine pattern,
Neither can it be applied on a fabric having irregularities in the weave or stitch.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a transfer foil capable of transferring fine and delicate patterns with good reproducibility even on a cloth having irregularities in a weave or stitch.

[0004]

The present invention has solved the above problems by using glass beads and color copy.

In the transfer foil of the present invention, a single layer is formed by partially embedding glass beads in a releasable resin thin film provided on a transparent resin film, and a resin coating layer is formed on the glass beads. It is a layer in which a colored pattern by color copying and a hot melt adhesive layer are sequentially laminated.

[0006] The transparent resin film may be any as long as it can substantially see through the pattern formed thereon, and may be translucent. As this film, any of plastic films such as polyester, nylon and olefin can be used, but it is necessary to have excellent dimensional stability and to withstand the temperature during color copy and transfer. Preferably, a polyester film is used.

The releasable resin thin film provided on such a transparent resin film can hold glass beads partially buried, but is peeled off from the glass beads together with the film after transfer. Yes, it is preferably made of a thermoplastic resin such as a polyurethane resin.

It is preferable to use glass beads having a diameter of usually 40 to 100 μm.
Submerge about 3 and make a single layer glass bead surface (curved surface)
It is preferable that the glass beads be stably held in a state where the glass beads are exposed.

Next, the resin coating layer applied on the glass beads only needs to cover the surface of the glass beads and form a color-copyable plane thereon.
It is usually formed using a thermoplastic resin such as polyester, acrylic, or urethane, but it is applied on a glass bead layer with irregularities, so it is coated with a comma coater, reverse coater, gravure coater, etc. preferable.

Color copying on the resin coating layer may be performed by copying a desired pattern with a commercially available color copying machine to form a colored pattern. However, at the time of this copy,
The resin coating layer needs to be formed so as to cover the glass beads appropriately so that the copy machine and the copy layer are not damaged by the glass beads.

Further, a hot-melt adhesive layer is formed on the colored pattern formed by color copying, and this is an adhesive layer for thermally transferring the colored pattern having glass beads on the surface to the object to be transferred. As the hot melt adhesive, commercially available ones, for example, nylon resin, urethane resin,
Although any of polyolefins and the like can be used, it is preferable to use a nylon resin or a urethane resin from the viewpoint of washing resistance after transfer, and usually, a hot-melt nylon resin powder and / or a urethane-based adhesive is used. It is preferable that the adhesive layer is formed by screen-printing the mixture containing the urethane resin powder.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
The present invention will be described in more detail. Example 1 The transfer foil of FIG. 1A is provided with a release resin thin film 2 of about 30 μm thick made of thermoplastic polyurethane on a transparent resin film 1 of 75 μm thick polyester film, and a diameter of about 30 μm. Glass beads 3 of 40 to 100 μm were embedded in a single layer by applying heat and pressure, and a resin coating layer 4 made of thermoplastic polyurethane was formed thereon by a gravure coater. Next, a photograph to be used as a transfer pattern was copied on the resin coating layer 4 with a color copying machine to obtain a beautiful colored pattern 5 as shown in the photograph. A resin solution obtained by mixing a polyurethane resin solution with a nylon resin powder functioning as a hot melt adhesive was screen-coated on the colored pattern 5 to form a hot melt adhesive layer 6.

The transfer foil thus obtained has a color pattern 5
Can be seen through the transparent resin film 1, the hot melt adhesive layer 6 is applied to the shell knitted fabric 7 having irregularities on the surface, and heated and pressed from above the transparent resin film 1, and the glass 7 The colored pattern 5 having the beads 3 was transferred.

The product obtained by peeling the transparent resin film 1 together with the resin thin film 2 can accurately form the colored pattern 5 similar to the original photograph, despite the fact that the cloth 7 has irregularities of the shell knitting on the surface. It became something to represent.

The transfer surface was smooth and very pleasant due to the presence of the glass beads, and the appearance became three-dimensional and very nice as if a colored pattern was provided on frosted glass.

Example 2 A transfer foil was manufactured in the same manner as in Example 1 except for the process of manufacturing the hot melt adhesive layer. For the formation of the hot-melt adhesive layer, a resin solution in which a urethane-based resin powder functioning as a hot-melt adhesive is mixed into a polyurethane resin solution is used. Instead, to fit some of its patterns,
Screen-printed in a pattern.

The transfer foil obtained in Example 2 was prepared by applying a hot-melt adhesive layer to a shell knitted fabric having irregularities on the surface, and applying heat and pressure from above the transparent resin film to form glass beads on the fabric. Was partially transferred in a pattern. In this transfer pattern, since the transfer foil had a glass bead layer, a part of the colored pattern was transferred into a beautiful and beautiful pattern corresponding to the pattern to which the hot melt adhesive layer was applied.

In the transfer foil of Example 2, as in Example 1, not only a three-dimensional transfer pattern can be obtained, but also a rubber-elastic urethane-based resin powder was used as a hot-melt adhesive, so that the transfer foil was transferred. The pattern became slightly elastic, and was very useful as a transfer foil to knits.

[0019]

The transfer foil of the present invention is capable of transferring a desired colored pattern with good reproducibility even on a fabric having an uneven surface, and the appearance of the transferred product is conventionally improved by the presence of glass beads. Without, it becomes something special.
