Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a transfer sheet material that allows desired characters and designs to be transferred to other parts with a simple operation.

In order to transfer desired characters and designs using general transfer foil, it must be pressed using a press machine with corresponding markings, and the disadvantage is that the equipment is large and cannot be easily used by end users. There is.

As an improved version of the transfer foil, the Japanese Patent Publication No. 67-1716
Some of them are described in Japanese Patent Publication No. 58-9670 and Japanese Patent Publication No. 58-9670.

In these general transfer foils, a water-soluble or solvent-soluble release layer is provided between the support and the transfer layer, and the adhesive layer is made of an adhesive that does not dissolve in water or solvent. , is formed into a pattern, and then washed with water or solvent to remove parts other than the characters and design.
This is a pattern-shaped transfer layer that remains, and in use, the character or pattern-shaped transfer layer is adhered to other parts by simply applying pressure or heating from the support side.

These transfer foils do not require the use of a press or the like during transfer, but the manufacturing process of the transfer foil includes a cleaning process to remove the excess transfer layer, which poses problems in waste liquid disposal, etc. There are problems such as restrictions on the types of mold release agents and adhesives that can be used.

In view of the above points, the present invention aims to provide a transfer foil that does not include a cleaning step in the manufacturing process and can be easily used even by end users.

That is, the present invention provides a sheet material in which a transfer layer consisting of a color layer and an adhesive layer, and a release sheet are laminated in this order on one side of a flexible support having mold releasability,
Pressure is applied to at least a portion of the sheet material from the support side so that the transfer layer in the area where the pressure is applied when peeling the release sheet can be peeled off as one with the release sheet;
The present invention also relates to a transfer sheet material in which the transfer layer in areas where no pressure is applied constitutes desired characters and patterns, and is applied so as to remain on the support side and hang.

Next, the present invention will be explained based on the drawings.

FIG. 1 is a schematic partial sectional view showing an embodiment of the transfer sheet material of the present invention.

In FIG. 1, (1) is a flexible support, and a release layer (2) is formed on one side of the support (1). A colored layer (3) consisting of a metal vapor deposition layer, a colored resin layer, etc., and an adhesive layer (4) consisting of a pressure-sensitive adhesive, a heat-sensitive adhesive, etc. are formed in this order on the release layer (2). Color layer (8)
The transfer layer (5) is composed of the adhesive layer (4) and the adhesive layer (4). A release sheet (6) is attached on top of the adhesive layer (4). Pressure is partially applied to such sheet material from the side of the support (1), as shown in FIG. 2, if necessary with heating. (E) is a stamp made by a press machine, and has four parts (1υ) of desired characters and designs. When pressure is applied from the side of the support (1) with such a stamp (1o), the area to which pressure is applied is Separation interface (7) is formed at the boundary between the transfer layer (5a) and the transfer layer (5b) in the area where no pressure was applied corresponding to the four parts (11) of the stamp α0), and the area where pressure was applied. The transfer layer (5a) is the transfer layer N of the area where no pressure is applied.
(5b) is more firmly adhered to the release sheet (6).

As shown in Figure 1, although it is still integrated as a whole, a release sheet (
When peeling 6), the transfer layer (5a) in the pressure area is separated from the transfer layer (5b) in the non-pressure area at the separation interface (7) and peeled off as one with the release sheet (6). The material of the transfer sheet is changed so that the transfer layer (5b) in the unpressed area can remain on the side of the support (1).

The transfer sheet material of the present invention as described above is used as described above. FIG. 3 is a sectional view showing a state in which the mold release sheet (6) is peeled off during use. When the release sheet (6) is peeled off, the transfer layer (5a) in the pressurized area is separated from the transfer layer (5b) in the non-pressure area at the separation interface (7) and also separated from the release M (2). The transfer layer (5b) having the desired characters and designs in the unpressed area remains on the support (1) side.

The intermediate transfer material in which the transfer layer (5b) having the desired characters and designs remains is placed on the surface to be decorated (8) on the side of the transfer layer (5b) as shown in FIG. layer(
Depending on the type of transfer layer (5), simply press it with your fingertips, spatula, etc., or heat it with an iron, iron, etc.
b) is applied to the surface to be decorated (8) and then to the support (1)
By peeling off the layer, a transfer layer (5b) of desired characters and designs is replaced on the surface to be decorated (8) as shown in FIG.

However, in the present invention, the characters on the transfer layer,
It does not include a cleaning process to remove parts other than the design, so there are no problems with waste liquid disposal. Furthermore, in order to transfer using the transfer sheet material of the present invention, a press machine or the like is not required, and the desired characters or designs can be created by simply pressing with a fingertip or the like after peeling off the release sheet, or by heating and pressing with an iron or the like. can be transcribed, so anyone can easily use it.

As the flexible support (1), materials similar to those used in conventional transfer foils may be used without particular limitation, such as polyester film, polyamide film, polycarbonate film, polypropylene film, polyethylene film, polyvinyl chloride film, etc. A resin film having a thickness of approximately 5 to 50 μm is preferably used, and paper may also be used.

The release layer (2) is provided when the releasability of the transfer layer (5) is poor, and depends on the type of support (1) and the color layer (3).
) If the releasability of the transfer layer is good due to the combination of types, it is not necessary to provide the above. The release layer (2) is made of, for example, cellulose acetate butyrate, acrylic resin, chlorinated polyolefin,
It is formed using resins such as chlorinated rubber, rubbers, or waxes.

As the colored layer (3), for example, a colored resin M or a metal vapor deposited layer, or a combination of an uncolored or colored resin layer and a metal vapor deposited layer is used. In particular, a combination of a resin layer and a metal vapor deposited layer that becomes a protective layer for the metal vapor deposited layer after transfer is preferable.
At that time, by coloring the resin layer with a transparent colorant, various metallic luster colors can be obtained. Examples of the resin for the resin layer include thermosetting resins such as urea resin, melamine resin, maleated rosin, and polyurethane, thermoplastic resins such as vinyl chloride-vinyl acetate copolymer, nitrocellulose, polyester, acrylic resin, and polyamide. , a mixture of the thermosetting resin and a thermoplastic resin, and the like. The thickness of the resin layer is usually about 0.5 to 6 μm. Metals for the metal vapor deposition layer include aluminum, zinc, copper, chromium, nickel,
Single metals such as silver, gold, platinum, or alloys of two or six or more of these metals may be used, and the thickness may be 30 to 150 mm.
It is about mμ.

The adhesive layer (4) is formed using a pressure-sensitive adhesive (including adhesive,
The same applies hereinafter) and a heat-sensitive adhesive can be used. As the pressure-sensitive adhesive, one mainly composed of a carboxyl group-containing polyacrylate such as a copolymer of an acrylic acid alkyl ester such as 2-ethylhexyl acrylate or butyl acrylate and acrylic acid or methacrylic acid is used. Further, as the pressure-sensitive adhesive, a pressure-sensitive adhesive encapsulating four microphones can also be used. Examples of the pressure-sensitive adhesive for encapsulating microphones include solvent-reactivated capsule adhesives using polyisobutylene, polyvinyl ether, polysiloxane, or the like as an adhesive base. Such encapsulated pressure-sensitive adhesives significantly shorten the time required for reactivation compared to conventional pressure-sensitive adhesives where the dry coating film is not sealed with a solvent before bonding, and the time required for reactivation is significantly shortened. Since the initial adhesive strength is changed and the surface of the adhesive layer is non-adhesive, plain paper can be used as the release sheet (6).

As the heat-sensitive adhesive, those mainly made of vinyl acetate resin, acrylic resin, styrene resin, cellulose, polyamide, alkyd resin, etc. are used.

As the release sheet (6), normal paper can be used as paraffin,
Copolymers of silicone resins, fluororesins such as polytetrafluoroethylene, monomers such as acrylic esters, vinyl esters, vinyl ethers, acrylamides, maleic acid derivatives, allyl esters, and functional group-containing monomers, or copolymers of these monomers with polyvinyl alcohol, The material used is one that has been subjected to a mold release treatment with a mold release agent such as a gray copolymer with cellulose or the like. Additionally, plain paper may be used in some cases.

Release M (2) and color layer (3) on one side of flexible support (1)
, an adhesive layer (4) is sequentially formed, and a release sheet (6) is pasted on the adhesive layer (4).

The thus obtained laminated sheet is pressed or heated from the side of the support (1) using a press having a stamp 00) as shown in FIG. When the adhesive layer (4) is made of a pressure-sensitive adhesive, it is usually sufficient to apply only pressure, but heating may also be applied, and when the adhesive layer (4) is made of a heat-sensitive adhesive, heating and pressure are applied.

By the pressure treatment, a separation interface (7) is formed at the boundary between the transfer layer (5a) in the pressed area and the transfer layer (5b) in the unpressed area, and the transfer sheet material of the present invention is changed.

In the transfer sheet material of the present invention, the adhesive strength between the transfer layer (5b) and the release sheet (6) in the non-pressure area is the adhesive strength between the transfer layer (5b) and the support (1). Of course, the adhesive strength between the transfer layer (5a) and the release sheet (6) at the pressurized area is smaller than that between the transfer layer (5a) and the support (1). It is necessary that the adhesive strength is greater than that of .

For this purpose, it is necessary for the adhesive layer of the transfer layer (5a) at the pressurized area to adhere to the release sheet (6) somewhat strongly when pressure is applied or heated and pressurized. It is necessary to appropriately select the type of mold release sheet (6) and the type of release sheet (6). For example, a combination of an acrylic pressure-sensitive adhesive and a silicone resin-treated paper, a combination of a microcafuslated pressure-sensitive adhesive and plain paper, a combination of a vinyl acetate-based heat-sensitive adhesive and a polyethylene-treated paper, etc. are suitable.

As described above, the transfer sheet material of the present invention has the following characteristics:
During use, apply the release sheet (6) to the transfer layer (5a) at the pressurized area.
By peeling off the transfer layer (5b) as one piece, the transfer layer (5b) in the unpressurized area remains on the support (1) side, and by overlaying and transferring the obtained intermediate transfer material on other parts, desired characters and designs are formed. The transferred image can be transferred to other objects.

The transfer sheet material of the present invention is suitably applied to art materials, stationery, play equipment, drafting, design, lettering, expression of family crests on Japanese and Western products, decoration of Buddhist altar fittings, crafts, etc.

Next, the present invention will be explained with reference to Examples.

Example 1 A release layer with a thickness of 0.2 μm made of heptalyl-acetate butyrate was formed on a long polyethylene terephthalate film with a thickness of 12 μm, and 60 parts of urea-melamine resin (parts by weight, the same applies hereinafter) ), 20 parts of polyisocyanate, maleated rosin 47M, *Osibon orangel v (:sAs
'fP's yellow-orange transparent organic pigment) 1 part thick.
A 5μ thick colored transparent resin layer is formed, on which an 80μ thick aluminum vapor deposited layer is formed by vacuum evaporation, and on top of that a 4μ thick pressure sensitive adhesive made of 2-ethylhexyl acrylate-acrylic acid copolymer. A layer of adhesive was formed, and then a release paper treated with silicone resin was pasted thereon.

Using a stamp having desired characters and designs as recesses, the laminated sheet was stamped at 6 to 5 kp/Cm2 (1') from the support side.
J Pressed under pressure. After applying this press treatment to the entire surface of the laminated sheet at appropriate intervals, the resulting transfer sheet material was cut into a desired size and the release paper was peeled off. The transfer layer was peeled off as one piece with the support, and the transfer layer in the non-pressurized area, that is, the transfer layer in the form of letters and designs remained on the support side.

The resulting intermediate transfer material was placed on top of ordinary paper so that the transfer layer was in contact with the paper, and when the support was peeled off after pressing strongly with the tip of a finger, golden glossy letters with clear outlines appeared on the paper. , the transfer image of the design was changed.

Example 2 In Example 1, the pressure-sensitive adhesive layer was formed into a micro-cafusselized pressure-sensitive adhesive (PODT-1 manufactured by Nippon Capsule Products ■).
A transfer sheet material was prepared in the same manner as in Example 1, except that 01) was used and plain paper was used as the release paper.
Transfer was performed using it.

As a result, the letters and designs were transferred to a shiny golden color with clear outlines.

Example 3 A heat-sensitive adhesive layer with a thickness of 2μ made of vinyl acetate resin was used instead of the pressure-sensitive adhesive of Example 1, and polyethylene-treated paper was used as the release paper.The press treatment was performed at 12,000.5K.
A transfer sheet material was prepared in the same manner as in Example 1 except that the test was carried out under the conditions of g/c-.
Transfer was carried out in the same manner as in Example 1, except that it was pressed with a 0'o iron.

As a result, the letters and designs were transferred to a shiny golden color with clear outlines.
