By overlapping secondary transfer members having transfer surfaces and bonding them under heat, a transfer surface with the desired matte state or pattern can be obtained at the desired location, and the transfer layer firmly adheres to the transfer target substrate. They discovered that this is the case, and came up with the present invention. [0010] That is, the transfer medium of the present invention includes a thermal transfer sheet for primary transfer, which is formed by sequentially laminating a primer layer, an ink layer, and an adhesive layer on a base sheet, and a secondary thermal transfer sheet having a transfer surface of a desired shape. It is characterized by comprising a transfer member. [0011] Further, the thermal transfer printing method of the present invention includes transferring a thermal transfer sheet for primary transfer, which is formed by sequentially laminating a primer layer, an ink layer, and an adhesive layer on a base sheet, onto a substrate to be transferred, and then printing a desired image onto a substrate. The shape of the transfer surface is secondarily transferred by overlapping and heat-pressing the secondary transfer members having transfer surfaces having the shape of , and the transfer layer and the transfer target base material are firmly adhered. shall be. [0012] Further, the transfer material of the present invention comprising a transfer target substrate and a transfer layer is a transfer material for primary transfer in which the transfer layer is formed by sequentially laminating a primer layer, an ink layer, and an adhesive layer on a base sheet. It is characterized in that it is formed by transferring a thermal transfer sheet to a transfer target substrate, overlapping a secondary transfer member having a transfer surface of a desired shape, and bonding them under heat and pressure. [0013] The present invention will be described in detail below. First, the transfer medium of the present invention will be explained. The transfer medium of the present invention includes a thermal transfer sheet for secondary transfer and a member for secondary transfer. The thermal transfer sheet for subsequent transfer basically consists of a base sheet, a primer layer, an ink layer, and an adhesive layer. [0014] As a general rule, the base sheet may be one that is used for this type of transfer sheet, and its thickness is usually preferably 10 to 60 μm, more preferably 12 to 2 μm.
It is 5 μm. Specifically, polyesters such as polyethylene terephthalate and polybutylene terephthalate,
Polyolefins such as polypropylene and polyethylene,
These include films, paper, and synthetic paper made of synthetic resins such as nylon and polyamide. These can be laminated and used if necessary. [0015]Although the primer layer may be formed directly on the base sheet, it is preferable to provide the primer layer with a release layer interposed therebetween. Examples of the release agent that forms the release layer include silicone resins, fluorine thread resins, cellulose derivative resins, and the like. These resins can be used alone or in combination of two or more. The thickness of the release layer is usually preferably 0.1 to 1.0 μm, more preferably 0.1 μm to 1.0 μm.
It is 2 to 0.5 μm. Note that a release wax, silicone, etc. may be added to the release agent for the purpose of improving the release effect. [0016] The resin component forming the primer layer is a resin that has a certain degree of flexibility and abrasion resistance as the outermost layer of a printed product, and has heat resistance enough to withstand the heat and pressure bonding described below. Thermosetting resins are preferred. Examples of the thermosetting resin include acrylic resins such as acrylic polyols, ester resins, urethane resins, and the like. Further, polyamide resins such as nylon can also be used as resins for the primer layer. The resin for the primer layer above is
It is preferable to use it by dissolving it in a solvent such as an aromatic hydrocarbon such as toluene or xylene, a ketone such as methyl ethyl ketone or methyl isobutyl ketone, an ester such as ethyl acetate or methyl acetate, or an alcohol such as propatool or butanol. The above solvents may be used alone or in combination of two or more. [0017] The thickness of the primer layer is usually 0.5 to 3.0 g/m2.
is preferable, more preferably 1.0 to 2.0 g/rn2
It is. [0018] The type of ink forming the ink layer is determined by taking into account the application and the structure of the transfer sheet. Normal ink has a binder (vehicle) made of thermoplastic resin, colorant, plasticizer,
Stabilizers, other additives, solvents, diluents, etc. are added and kneaded. [0019] The binder needs to be a thermoplastic resin in order to perform thermal transfer, but it is preferable that it contains some thermosetting resin in order to improve surface hardness (wear resistance) and the like. As the thermosetting resin, the same resins as those for the primer layer described above can be used, such as acrylic resins such as acrylic polyols containing thermosetting monomers, ester resins, urethane resins, and polyamide resins such as nylon. . Further, the binder preferably contains a crosslinking agent to improve thermosetting properties, and it is particularly preferable to use incyanate as the crosslinking agent. [0020] Pigments are also used as the coloring agent. The pigment is not particularly limited and may be appropriately selected depending on the desired hue. Specifically, inorganic pigments such as iron oxide, ultramarine, and titanium dioxide carbon black, organic pigments such as azo pigments, anthraquinone pigments, lakes, and phthalocyanine pigments, and metal powders such as aluminum powder and copper powder are used. be able to. [0021] The thickness of such an ink layer is generally 1.0 to 3.0 g.
/m2. Examples of resins forming the adhesive layer include rubber resins such as polyisoprene rubber, polyisobutyl rubber, styrene butadiene rubber, butadiene acrylonitrile rubber, (meth)acrylic acid ester resins, polyvinyl ether resins, polyvinyl acetate resins, So-called hot melt type adhesives made of thermoplastic resins such as vinyl chloride-vinyl acetate copolymer resins, polystyrene resins, polyester resins, polyamide resins, polychlorinated olefin resins, and polyvinyl butyral resins can be used. can. [0022] The thickness of the adhesive layer is generally 1.0 to 30 g/m
Preferably it is about 3 to 15 g/m2. In addition,
The adhesive layer does not need to be provided on the entire surface of the ink layer.
It is provided as many times as necessary depending on the adhesion between the ink resin and the transfer target substrate. [0023] A method for producing a thermal transfer sheet for primary transfer consisting of resins for each layer as described above includes a resin for a release layer formed on a base sheet as necessary, a resin for a primer layer, and an ink as necessary. After diluting to a viscosity suitable for application, it is coated using known coating methods such as reverse roll coating, roll coating, gravure coating,
The coating is sequentially applied to the desired layer thickness using kiss coating, blade coating, smooth coating, etc. Subsequently, a resin for the adhesive layer is coated on top. Note that the melting temperature of the adhesive may be appropriately set within the range of 50 to 160°C depending on the resin used. [0024] Examples of the secondary transfer member in the present invention include the following. First, if you want a surface patterned with a geometric pattern, regular or irregular mesh pattern, etc., for example, ink with a heat-resistant resin as a binder is applied onto a film such as polyethylene terephthalate to create a mesh pattern. Use one printed in the desired pattern. Note that the pattern of the secondary transfer member does not need to be present on the entire surface thereof, and may be provided at a desired location as necessary. [0025] If a matte surface (matte surface) is desired rather than a pattern, a surface of ordinary pure white roll paper, kraft paper, etc., or a woven or non-woven fabric of cotton cloth, linen cloth, or other various fibers may be used. You can use the surface as it is, and it will become matte depending on the surface of the paper or fiber used. [0026] Next, a thermal transfer printing method of the present invention using a transfer medium consisting of the above-described thermal transfer sheet for primary transfer and a member for secondary transfer will be described. [0027] First, the above-described thermal transfer sheet for primary transfer is transferred (hereinafter referred to as "secondary transfer"). - The next transfer is preferably performed by heating using a heat roll or the like. At this time, the adhesive layer surface of the second transfer sheet is brought into contact with the transfer target substrate to perform thermocompression bonding. In addition,
The temperature and pressure of thermocompression bonding using a hot roll etc. may be set appropriately depending on the resin forming the adhesive layer, but usually,
Temperature is 120-200℃, preferably 130-180℃
and the pressure (linear pressure) is 3 to 30 kg/cm, preferably 5
~15 kg/cm, and the feeding speed of the hot roll is preferably 20 m/min or less, preferably 5 to 15 m/min. [0028] Various materials can be used as the transfer substrate, but the method of the present invention is particularly applicable to artificial leather having a urethane-based or vinyl chloride-based resin layer, raw leather cloth such as synthetic leather, etc. suitable for As raw leather cloth such as the above-mentioned artificial leather or synthetic leather, it is also possible to use materials that have been subjected to processes such as graining and embossing in advance. [0029] Note that the vinyl chloride sheet may not be subjected to graining, embossing, etc. in advance, but may be grained, embossing, etc. after thermal transfer. [0030] In addition to the above, fibrous materials such as woven or non-woven fabrics of various fibers such as natural fibers such as cotton, hemp, silk, and wool, semi-synthetic fibers such as rayon and acetate, and synthetic fibers such as nylon and polyamide resins, etc. It is also applicable to structures. [0031] If only the next transfer is performed in this way, the surface of the base sheet will be in a glossy state or a monotonous matte state, so in the present invention, as described above, The primary transfer target base material and the secondary transfer member having a transfer surface of a desired shape are superimposed and bonded under heat and pressure, and then the secondary transfer member is peeled off. The above-mentioned secondary transfer is preferably performed by a flat press. [0032] The conditions for secondary transfer (temperature, pressure, time, etc.) may be appropriately set depending on the heat resistance of the transfer substrate used, but in the case of flat press, the temperature is usually 130 to 160°C. , preferably at a temperature of 130 to 150°C and a pressure of 0.5 to 3 kg/cm
Preferably 0.5 to 1 kg/cm2 and 20 seconds to 2
It is only necessary to press for about 30 to 60 seconds. [0033] If the pressure of the secondary transfer exceeds 3 kg/cm2, not only will no further effects such as matting be obtained, but if the transfer base material has grain, the grain will be crushed. . For example, when urethane synthetic leather is used as the transfer substrate, the temperature is 110 to 160°C and the pressure is 0.5 to 3 kg/cm.
The heating time may be 2 hours and 30 to 60 seconds, and the temperature, pressure, time, and conditions may be set depending on the material such as the raw material of synthetic leather so as not to damage the planar state of the grains, etc. In addition, when using cotton canvas, etc., the temperature is 180-200℃, approximately 3kg/cm
It should be about 2 hours and 30 seconds. [0034] In addition, when the secondary transfer is performed not by a flat press but by a hot roll, 130 to 200' C1, preferably 150 to 2
At 00°C, the pressure (linear pressure) is 0.5 to 3 kg/cm, preferably 0.5 to 1 kg/cm, and the feeding speed of the hot roll is 20 m/min or less, preferably 5 to 10 m/min. The overlapping and heating of the above-mentioned secondary transfer members at the time of the next transfer may be performed simultaneously. [0035] The transfer material obtained by such secondary transfer has a surface such as cow or sheep leather, suede or crocodile skin,
It has a desired surface such as a matte surface of various gloss. Moreover, in this transfer material, the transfer layer and the transfer substrate are firmly adhered, and the adhesive strength is 100/100 in a tape peel test. [0036]

[Effect]

In the thermal transfer printing method of the present invention, a thermal transfer sheet for primary transfer having a primer layer, an ink layer, and an adhesive layer on a base sheet is transferred to a transfer substrate, and a thermal transfer sheet for secondary transfer having a desired pattern is transferred. Since the members are superimposed and bonded under heat and pressure, the resulting transfer material has the desired pattern at the desired location, and the transfer layer is firmly adhered to the transfer target substrate. [0037] The reason why such an effect is obtained is not necessarily clear, but the conditions for secondary transfer are usually lower temperature, lower pressure, and longer time than for primary transfer. The matte state and pattern of the transfer member are transferred without damaging the surface pattern of the transfer substrate itself, and the adhesive layer of the thermal transfer sheet for the next transfer is plasticized to follow the undulations of the surface of the transfer substrate. This is thought to be due to the fact that they fit tightly together. [0038]

The state in which the substrate sheet 1 has been transferred and the base sheet 1 has been peeled off (-next printed product) is shown. [0040] FIG. 3 shows a secondary transfer material in which a secondary transfer member 8 printed with a pattern 9 of a desired shape is superimposed on the secondary transfer printed material of FIG. An example of the transcription process is shown. [0041] Furthermore, FIG. 4 shows a state in which the base sheet 8 is peeled off after the secondary transfer shown in FIG. A pattern similar to pattern 9 is transferred to this transfer material. [0042] Although the transfer method of the present invention has been described above with reference to the drawings, the present invention is not limited thereto, and various changes can be made without departing from the spirit of the present invention. [0043] In the example, a 25 μm thick polyethylene terephthalate film (manufactured by Toyobo Co., Ltd., untreated raw film) was used as the base sheet, and one side of the film was coated with a release layer, a primer layer, and yellow, red,
The resin required for ink of each color, indigo and black, is coated one after another at a speed of 60 m/min using a gravure printing machine (6-color machine), and then a hot adhesive is gravure coated on the surface of this ink layer. A thermal transfer sheet for transfer was created. The printing speed of the adhesive was 30 m/min, and the amount of adhesive applied was 12 g/m2 in terms of dry weight. [0044] The thus obtained thermal transfer sheet for secondary transfer and a cotton canvas (thickness 0.4 mm) were overlapped, and a heat roll (1
30℃) and the cotton roller with a linear pressure of 10kg/c.
When the base sheet was peeled off at a speed of 10 m/min, a pattern printed with yellow, red, indigo, and black ink was obtained on the surface of the cotton canvas. This printed product had gloss over the entire surface. Further, the tape peel strength of this transfer sheet was measured by a base grain test (base grain number = 100) and was found to be 5/100. [0-045] In addition, the base grain test and test are 1 mm x 1 mm on the transfer sheet.
100 base squares were formed by warping, a peeling test was performed using cellophane tape, and the number of squares remaining without peeling (X)
counted and displayed the number. [0046] Next, this print was superimposed on the back side (unsmooth side) of pure white roll paper (manufactured by Kishu Paper Co., Ltd., product name: Hamayu, basis weight 40 g/m2), and a flat press manufactured by Canegie Co., Ltd. was used. After heat-pressing for 30 seconds at 200° C. under a pressure of 3 kg/cm 2 in a machine, the pure white roll paper was peeled off, and a printed product with a matte finish was obtained on the entire surface. In addition, when the tape peel strength of this printed product was measured in the same way,
The ratio was 100/100, and it was confirmed that the adhesive strength was improved compared to the second transfer material. [0047] Furthermore, when the color fastness of the obtained prints was examined (number of samples, n=3), all of them showed grades 4 to 5, and there were no problems in practical use. In addition, the printed material was sufficiently soft to the touch.
