Description

  The present invention relates to a transfer sheet for thermally transferring a pattern to a transfer target portion having flexibility and / or stretchability in an object such as clothing made of cloth-like fiber products or other objects, and the transfer sheet. The present invention relates to a transfer object manufacturing method for manufacturing a transfer object on which a pattern is transferred and used, and a transfer object on which a pattern is transferred and formed using the transfer sheet.

  Conventionally, as a means for forming a pattern on a cloth-like fiber product (generally, a fiber product colored by dyeing or the like) constituting clothing, a colored ink having a concealing property is applied to the fiber product. Direct printing to form a pattern by printing or forming a pattern by forming a concealing layer on the textile with a white ink having a concealing property, and printing and laminating colored ink on the concealing layer And a transfer sheet by laminating a release layer, a design layer, and an adhesive layer in this order on a base sheet made of heat-resistant paper or a synthetic resin film, and a hot press machine or iron on the textile product. There is known a thermal transfer method in which the adhesive layer of the transfer sheet is thermally fused under pressure to transfer the pattern and then the base sheet is peeled off.

  The direct textile printing method cannot be said to be efficient because it has to form a pattern by performing textile printing on each textile product, and it requires skill in the work.

  On the other hand, in the case of the thermal transfer method described in Japanese Patent Application Laid-Open No. 5-287686, etc., it is easily transferred by printing a release layer, a pattern layer, and an adhesive layer on a base sheet with a resin ink in order using a printing machine. A sheet can be prepared, and a large number of transfer sheets can be obtained by forming a large number of release layers, design layers, and adhesive layers on a single base sheet at a time and then separating the base sheet. In addition, by using the transfer sheet to heat-bond the adhesive layer onto the fiber product with a hot press or an iron under pressure, it is possible to transfer and form a delicate and clear and strong design.

  Thus, according to the thermal transfer method, a pattern can be efficiently formed on the fiber product. The transfer sheet in this thermal transfer method requires a hot melt adhesive layer mainly composed of a resin using a hot melt adhesive or the like.

  However, when printing a release layer, a design layer, and an adhesive layer on the base sheet with resin ink, the design layer is limited by the expansion and contraction of the base sheet according to the temperature and humidity during printing, the accuracy limit of the printing machine, etc. On the other hand, it is difficult to accurately match the adhesive layers.

  Therefore, in order to ensure that the entire design can be transferred onto the textile product, the adhesive layer should be formed slightly larger than the design layer, that is, the periphery of the adhesive layer should protrude from the periphery of the design layer. It is necessary to form. Specifically, the peripheral portion of the adhesive layer forming portion in the plate for printing the adhesive layer is enlarged by about 0.2 to 2.0 mm from the peripheral portion of the graphic layer forming portion in the plate for printing the design layer. The adhesive layer is printed and formed using a resin ink that is substantially colorless and transparent when transferred onto a textile product.

  When a pattern is transferred and formed on a textile product, the peripheral edge of the adhesive layer protrudes from the peripheral edge of the pattern to form a protruding edge, but the appearance of the protruding edge is substantially colorless and transparent. The appearance such as the color of the transfer target portion appears substantially as it is through the edge portion, and it does not change in appearance. Therefore, the outline of the transferred pattern is clear.

  However, since the adhesive layer is directly fixed to the transfer target portion to which the design has been transferred by thermal fusion, if the transfer target portion is repeatedly subjected to deformation such as expansion and contraction and / or bending, strain and fine cracks are formed in the adhesive layer. As a result, the protruding edge of the adhesive layer becomes white due to irregular reflection or scattering of light (so-called whitening phenomenon), and the color of the protruding edge is clearly different from the color of the transfer target area. It tends to be a thing. As a result, the transferred pattern is unclear in its outline, or a protruding edge portion having an unnatural appearance on the peripheral edge appears remarkably, and the aesthetics are impaired.

JP-A-5-287686

  The present invention has been made in view of the above-described problems existing in the prior art, and the object of the present invention is an object made of cloth-like textile products such as clothing or other objects. The adhesive layer that protrudes from the peripheral portion of the pattern thermally transferred to the transfer target portion having flexibility and / or stretchability is deformed by stretching and / or bending due to movement of clothes, washing, etc. The transfer sheet can effectively prevent the appearance of the color and the like from changing repeatedly and the color of the protruding edge from being clearly different from the color of the transfer target area around the protruding edge. An object of the present invention is to provide a transfer object manufacturing method for manufacturing a transfer object having a pattern transferred and formed using a transfer sheet, and a transfer object having a pattern transferred and formed using the transfer sheet.

  The inventors of the present invention have made extensive studies in order to solve the above-mentioned problems. As a result, a base sheet that is peeled off after transfer, a pattern layer for forming a pattern on a transfer target portion of an object, and a resin as a main component By making the color of the part including the peripheral part of the adhesive layer in the thermal transfer sheet having the hot-melt adhesive adhesive layer in this order and the color of the transfer target part the same or similar colors As a result, it has been found that it is possible to effectively prevent the appearance of the color and the like from being clearly different from the transfer target portion even if the deformation is repeated, and the present invention has been completed through further research.

(1) The thermal transfer sheet of the present invention that achieves the above object,
A base sheet that is peeled off after transfer, a pattern layer for forming a pattern on a transfer target portion of an object, and a hot-melt adhesive layer having a resin as a main component in this order, and the adhesion The layer is heated while being brought into pressure contact with the transfer target portion having flexibility and / or stretchability in the object, thereby heat-adhering the adhesive layer to the transfer target portion and transferring the pattern by the pattern layer. The thermal transfer sheet of
The peripheral edge of the adhesive layer is formed so as to protrude from the peripheral edge of the pattern layer, and forms a protruding edge that protrudes from the peripheral edge of the pattern when transferred to the transfer target part.
All of the adhesive layer or a portion including a peripheral edge forming the protruding edge is colored with a colorant.

The method for producing a transfer object of the present invention comprises:
A transfer object manufacturing method for manufacturing a transfer object in which a pattern is transferred and formed on a transfer target part,
Any one of the above thermal transfer sheets is heated while being brought into pressure contact with the transfer target portion having flexibility and / or stretchability of the object in the adhesive layer, thereby thermally bonding the adhesive layer to the transfer target portion. Including a step of transferring a pattern by the pattern layer,
The color of the adhesive layer fused to the transfer target portion or the color of the portion including the peripheral edge forming the protruding edge portion and the color of the transfer target portion are the same or similar colors.

The transferred object of the present invention is
Any one of the above thermal transfer sheets is thermally fused to a transfer target portion having flexibility and / or stretchability in the object in the adhesive layer, and a pattern by the pattern layer is transferred and formed.
The color of the adhesive layer fused to the transfer target portion or the color of the portion including the peripheral edge forming the protruding edge portion and the color of the transfer target portion are the same or similar colors.

  The heat transfer sheet is heated while being brought into pressure contact with the transfer target portion having flexibility and / or stretchability of the object in the adhesive layer, whereby the hot melt adhesive layer is thermally fused to the transfer target portion. In this way, the design by the design layer can be transferred and formed. By peeling the base sheet in this state, a pattern transferred and formed on the transfer target portion appears.

  The peripheral part of the transferred adhesive layer forms a protruding edge part that protrudes from the peripheral part of the design. The color of the adhesive layer fused to the transfer target part or the color of the part including the peripheral part forming the protruding edge and the color of the transfer target part (at least the peripheral part of the part of the transfer target part where the adhesive layer is fused) By setting the color to the same or similar color, it is possible to prevent inconvenience from occurring at the protruding edge. That is, the transfer target portion to which the design has been transferred through the adhesive layer is repeatedly subjected to deformation such as expansion and contraction and / or bending (for example, distortion and fine cracks are generated in the adhesive layer), and the color of the protruding edge portion, etc. Is effectively prevented from being greatly different from the appearance such as the color of the transfer target portion around the protruding edge portion.

  (2) The thermal transfer sheet of the present invention is substantially colorless when all of the adhesive layer or a part including the peripheral edge forming the protruding edge is transferred to the transfer target part in a state excluding the colorant. It can be transparent.

  In the case where all of the adhesive layer or the part including the peripheral part forming the protruding edge is the one excluding the colorant, the adhesive layer transferred to the transfer target part protrudes from at least the peripheral part of the transferred pattern. Since the portion including the protruding edge is substantially colorless and transparent, the color and the like of the protruding edge are substantially the same as the color and the like of the transfer target portion through the substantially transparent and protruding edge. It will appear as it is and will not change.

  However, if the transfer target part to which the design is transferred through the adhesive layer is repeatedly subjected to deformation such as expansion and contraction and / or bending, distortion and fine cracks are generated in the adhesive layer, and the protruding edge part is diffused and scattered light. As a result, the appearance of the protruding edge portion, such as the color, becomes distinctly different from the appearance of the color of the transfer target portion around the protruding edge portion.

  However, the color of the adhesive layer fused to the transfer target portion or the color of the portion including the peripheral edge forming the protruding edge portion and the color of the transfer target portion are the same or similar colors, so that the adhesive layer is interposed. The transfer target part to which the design has been transferred repeatedly undergoes deformation such as expansion and contraction and / or bending, and the color and other appearance changes, and the appearance of the protruding edge color and the like is the color of the transfer target part around the protruding edge part. It is effectively prevented that the appearance is clearly different from the above.

  (3) In the thermal transfer sheet of the present invention, the protruding width of the peripheral portion of the adhesive layer from the peripheral portion of the design layer may be 0.2 to 2.0 mm.

  (4) Each of the thermal transfer sheets may have a release layer between the base sheet and the design layer.

  (5) Each of the thermal transfer sheets may have a concealing layer between the design layer and the adhesive layer.

  In this case, a dye adsorption layer can be provided between the adhesive layer and the hiding layer.

  (6) Each of the thermal transfer sheets may have a protective layer adjacent to the base sheet side of the design layer.

  (7) The thermal transfer sheet of the present invention is formed by spraying hot melt resin particles in a state in which the adhesive layer is formed of a liquid material containing a resin as a main component and the liquid material is not solidified. Can be.

  In this case, since the hot melt resin particles are located on the surface portion of the adhesive layer on the side pressed against the transfer target portion, the adhesive force of the adhesive layer to the transfer target portion is strong.

  In the thermal transfer sheet of the present invention, the adhesive layer may be formed of a liquid material containing a resin as a main component and hot melt resin particles.

  These hot melt resin particles can be made of polyurethane resin, nylon resin or polyester resin.

  (8) In the thermal transfer sheet of the present invention, the design layer may contain a resin as a main component, and the resin that is the main component of the design layer and the adhesive layer may be a polyurethane resin.

  (9) Each of the thermal transfer sheets of the present invention is for making the color of the protruding edge of the adhesive layer when transferred to the transfer target part and the color of the transfer target part the same or similar. can do.

  A transfer object using the transfer sheet of the present invention, a transfer object manufactured by the transfer object manufacturing method of the present invention, and an object such as clothing made of a cloth-like fiber product in the transfer object of the present invention Alternatively, the adhesive layer that protrudes from the peripheral portion of the pattern that has been thermally transferred to the transfer target portion having flexibility and / or stretchability in other objects can be stretched and / or stretched due to clothes being attached and detached, operation in clothes, washing, etc. Or, by repeatedly receiving deformation such as bending, the appearance of the color etc. changes greatly, and the appearance of the color of the protruding edge is greatly different from the appearance of the color of the transfer target part around the protruding edge. Prevents the outline of the pattern from being unclear, or the protruding edges that appear unnatural due to repeated deformation, etc., from appearing on the peripheral edge of the pattern, and the aesthetics of the pattern and transferred object from being impaired.

  1. Object

  The object to which the design is transferred by using the transfer sheet of the present invention, the whole or part of the object has flexibility and / or stretchability (that is, flexibility and / or stretchability). Consists of parts. The transfer target part is given some color or exhibits the color of the material itself.

  When the design of the transfer sheet is transferred to such a transfer target portion by thermal fusion of the adhesive layer, and the transfer target portion is repeatedly subjected to deformation such as expansion and contraction and / or bending, distortion, fine cracks, etc. are generated in the adhesive layer. As a result, the protruding edge portion of the adhesive layer becomes white due to irregular reflection or scattering of light.

  Examples of objects include colored cloth-like fiber products such as woven fabrics, knitted fabrics, and non-woven fabrics, fiber products made of such cloth-like fiber products (for example, clothing, hats, mufflers, socks, etc.), leather Or the product (for example, clothing, a belt, footwear, a hat, etc.) which uses leather as a material can be mentioned. A cloth-like fiber product or a fiber product made of a cloth-like fiber product is more suitable because it is rich in flexibility and stretchability. A part of the object is a transfer target part made of a flexible and / or stretchable material such as a cloth-like fiber product, or a cloth-like fiber product is acceptable except for a part of the object. It may be a transfer target portion made of a material having flexibility and / or stretchability.

  In addition, it is possible to transfer and form a pattern on a non-flexible or stretchable object or part using the transfer sheet of the present invention.

  2. Transfer sheet

  The transfer sheet of the present invention comprises a base sheet that is peeled off after transfer, a pattern layer for forming a pattern on a transfer target portion of an object, and a hot-melt adhesive adhesive layer mainly composed of a resin in this order. It is provided, and other layers and the like can be provided as necessary.

  (1) Base sheet (release paper or release film)

  After transferring the design, the base sheet is peeled from the design transferred and formed on the transfer target portion.

  In order to provide releasability between the base sheet and the design, a release layer is provided between the base sheet and the design layer (specifically, for example, a release layer is formed on the design layer side of the base sheet). It is also possible to employ a base sheet (for example, a sheet made of polytetrafluoroethylene, etc.) that itself has releasability.

  (1-1) As the base sheet, a material that can withstand transfer conditions (for example, transfer temperature 100 to 200 ° C., transfer time 2 to 30 seconds, transfer pressure 15 to 100 kPa) can be used.

  In general, paper or a synthetic resin film can be used as a base sheet. As the synthetic resin film, for example, a polyester film is preferably used. For transfer at a relatively low temperature, for example, a polypropylene film can be used.

  (1-2) Examples of the material for the release layer include wax, paraffin, silicone oil, silicone resin, fluorine resin, and resins having no adhesion to the base sheet. By using such a material, a thin film can be formed on at least one surface (the surface on the design layer side) of the base sheet, whereby this can be used as a release layer. Such a thin film can be formed, for example, by coating or printing. Thus, the sheet | seat in which the releasable thin film was formed turns into a release sheet.

  (2) Protective layer, design layer, concealment layer, dye adsorption layer, adhesive layer

  The protective layer, the design layer, the hiding layer, the dye adsorption layer, and the adhesive layer can each be formed of a material mainly composed of various resins and colored with various colorants as necessary. Usable resins include polyurethane resin, polyacrylate resin, polyvinyl chloride resin, vinyl chloride / vinyl acetate copolymer resin, ethylene / vinyl acetate copolymer resin, styrene / butadiene copolymer resin, polyester resin, nylon resin Etc. can be illustrated.

  A polyurethane resin is preferable as the resin for forming the protective layer, the design layer, the concealing layer, and the dye adsorption layer. As the hot-melt resin that can be used for imparting hot-melt adhesiveness to the adhesive layer, polyurethane resin, polyester resin, nylon resin, and the like are preferable, and these can be mixed and used.

  In order to form each layer using such a resin, it is necessary to use the resin as a resin ink by dissolving and / or dispersing it in an organic solvent, or by dispersing it in water, or by emulsifying it. preferable. Examples of other components of the ink include necessary colorants, curing agents, and other additives. Each layer can be formed by printing with such a printer using such ink (resin ink).

  The pattern layer can be formed by, for example, an offset printing method or a screen printing method. The concealing layer, the dye adsorbing layer, and the adhesive layer need to have a certain thickness in order to exert their functions, and therefore a screen printing method is preferable. For screen printing, for example, a polyester or nylon wrinkle of 30 to 350 mesh / inch is applied to an aluminum frame, a photosensitive emulsion is coated on the wrinkle, and a positive film with a desired pattern is overlaid for exposure. After that, the emulsion is washed away and dried. By placing ink on the obtained screen plate and printing it with a rubber squeegee or the like, a desired pattern layer or the like can be screen printed.

  In order to form the adhesive layer, for example, a resin ink having hot-melt adhesiveness is used, or ink obtained by dispersing hot-melt resin particles (having a particle diameter of, for example, about 20 to 80 μm) in the resin ink. Or hot-melt resin particles (having a particle diameter of, for example, about 80 to 300 μm) can be used on a layer formed of resin ink. Such hot melt resin particles can be obtained, for example, by forming into particles by polymerization or by pulverization.

  (2-1) Protective layer

  The protective layer is formed as necessary adjacent to the base sheet side of the design layer for the purpose of protecting the design by maintaining the surface strength of the design transferred to the transfer target portion, and is not essential. .

  Usually, the protective layer is colorless and transparent. The protective layer can be formed, for example, by printing or coating a resin ink on a release layer provided on the base sheet or on a base sheet having releasability.

  A base sheet in which a release layer (release agent layer) and a protective layer are previously formed by coating or printing can also be used.

  (2-2) Pattern layer

  The pattern layer is for forming a pattern on a transfer target portion of an object. For example, a protective layer is formed on a release layer provided on the base sheet or on a base sheet having releasability as necessary. For example, it can be formed by printing a resin ink.

  The symbol formed by the symbol layer can be, for example, a picture, a character, a figure, a symbol, or a combination of two or more thereof.

  As the resin ink for forming the pattern layer by printing or the like, those colored with various colorants such as organic pigments or inorganic pigments can be used.

Examples of colorants that can be used include:
Azo pigments, anthraquinone pigments, isoindolinone pigments, titanium pigments, iron pigments as yellow pigments;
Azo pigments, quinacridone pigments, diketopyrrolopyrrole pigments, chromophthal pigments, iron pigments as red pigments;
Phthalocyanine pigments as green or blue pigments;
Dioxazine pigments as purple pigments;
Carbon black as a black pigment, iron-based pigments;
Examples of the white pigment include, but are not limited to, a titanium oxide pigment, a silicon oxide pigment, and an aluminum silicate pigment. Any color mixed colorant in which two or more colorants are mixed can be used.

  In addition to the metal powder such as aluminum powder, aluminum paste, pearl pigment, brass powder, glitter, and the like as the colorant, special colorants such as temperature-sensitive color-changing pigments, photosensitive color-changing pigments, and luminous pigments can also be used. .

  (2-3) Concealment layer

  The concealing layer is formed in order to clearly display or lift the pattern on the transfer target portion, and can be generally formed on the pattern layer between the pattern layer and the adhesive layer. The concealing layer is usually colored with a white pigment or the like to form a white color that does not transmit visible light.

  The concealing layer is highly necessary when the transfer target portion is relatively dark, and is not necessary when the portion is light or light. When the color of the design is designed as a color mixture of the color of the design layer and the color of the transfer target portion or the color of the colored adhesive layer, the hiding layer is not used.

  When each of the hiding layer and the design layer is formed (particularly when formed by printing), the contours of the two do not necessarily coincide with each other accurately, so that the edge of the design layer should slightly protrude from the edge of the hiding layer. Alternatively, it is preferable that the concealing layer is part of the design such that the peripheral part of the concealing layer protrudes from the peripheral part of the design layer (that is, the concealing layer constitutes part of the design layer).

  The masking layer can be formed by, for example, an ink colored in white by blending titanium oxide, silicon oxide, aluminum silicate or the like as a masking agent (white pigment) with the resin ink as described above. It is also possible to form a concealing layer colored with a colorant other than white. The formation of the concealing layer can be performed, for example, by printing a resin ink.

  (2-4) Dye adsorption layer

  When the thermal transfer of the pattern onto the transfer target part made of polyester fiber dyed with disperse dye, the dye adsorption layer sublimates the disperse dye due to the heat during transfer and contaminates the pattern layer or the concealing layer. This is a layer for preventing the designability from being impaired.

  Therefore, it is not always necessary for a transfer target portion composed of fibers (for example, cotton, nylon, rayon, hemp, wool, silk, etc.) dyed with a dye having no sublimation property.

  The dye adsorption layer can be obtained as a black layer by, for example, blending activated carbon as an adsorbent into a substantially colorless and transparent resin ink obtained by converting the resin into an ink.

  The dye adsorption layer is formed between the design layer and the adhesive layer. When using a dye adsorption layer containing activated carbon, a masking layer is formed on the pattern layer, and by forming the dye adsorption layer on the masking layer, the clarity and clarity of the pattern layer is hindered by the dye adsorption layer. Is prevented. The dye adsorption layer can be formed, for example, by printing a resin ink.

  (2-5) Adhesive layer

  The adhesive layer is thermally fused to the transfer target part by being heated under pressure, and the pattern layer and, if present, the dye adsorbing layer, the hiding layer, the protective layer, and the like are firmly attached to the transfer target part. It is for fixing.

  The adhesive layer is mainly composed of a resin and has hot-melt adhesiveness. The adhesive layer is formed on the design layer, if necessary, by interposing a concealing layer and a dye adsorption layer, as described above, for example, a) using a resin ink having hot-melt adhesiveness, or b) It can be formed using ink obtained by dispersing hot melt resin particles in resin ink, or c) hot melt resin particles can be formed on a layer formed of resin ink. In the case of c), since the hot-melt resin particles are located on the surface portion of the adhesive layer that is the side pressed against the transfer target portion, the adhesive force of the adhesive layer to the transfer target portion is strong.

  The adhesive layer is formed such that the peripheral portion protrudes from the peripheral portion of the design layer (including the concealment layer when the concealment layer constitutes a part of the design layer). The protruding width of the peripheral edge portion of the adhesive layer from the peripheral edge portion of the design layer can be set to a substantially constant width in the range of 0.2 to 2.0 mm, for example, but is not limited thereto. In addition, a peripheral part contains an outer peripheral part and an inner peripheral part, when both an outer periphery and an inner periphery exist in a symbol like a cyclic | annular figure.

  The peripheral edge of the adhesive layer forms a protruding edge that protrudes from the peripheral edge of the design when the adhesive layer is transferred to the transfer target part. The protruding width of the protruding edge portion transferred to the transfer target portion may slightly increase or decrease compared to the predetermined width even when printing is performed to a predetermined width.

  The portion of the adhesive layer that protrudes from the peripheral portion of the design layer may be formed so as to surround the side portions of the design layer or the design layer and other layers. In this case, the protruding portion is the base sheet. It is formed on a release layer provided thereon or on a base sheet having releasability.

  In the adhesive layer, all or a part including a peripheral edge portion forming the protruding edge portion is colored with a colorant. As a result, all of the adhesive layer fused to the transfer target part or the color of the part including the peripheral part forming the protruding edge part and the peripheral part of the transfer target part (the part of the transfer target part where the adhesive layer is fused) Color)) can be the same or similar colors. In this case, the color difference ΔE * ab between the transfer target portion and all of the adhesive layer fused to the transfer target portion or the portion including the peripheral edge forming the protruding edge portion can be 12 or less. Preferably it is 6 or less, More preferably, it is 4 or less.

  Therefore, the following three types can be exemplified as the method for forming the adhesive layer. That is, 1) A substantially colorless and transparent resin ink having hot-melt adhesiveness is blended with a colorant and formed using a color that approximates the transfer target part. 2) A substantially colorless and transparent resin ink. 3) After forming a layer using a substantially colorless and transparent resin ink mixed with a colorant and forming a layer using a mixture of a colorant and a hot melt resin particle dispersed therein, the layer In addition, resin ink is obtained by spraying hot melt resin particles in a state where the ink is not solidified (solidification is not limited to solidification by solvent or evaporation of the solvent), and then removing the excess hot melt resin particles and performing heat treatment. And an adhesive layer in which hot melt resin particles are integrated.

  3. Transfer method

  The obtained heat transfer sheet is heated while being brought into pressure contact with the transfer target portion of the object in the adhesive layer using a hot press machine or an iron, so that the hot melt adhesive adhesive layer is heated on the transfer target portion. It is possible to transfer and form a design by the design layer by fusing. Thereafter, by peeling off the base sheet, the pattern transferred and formed on the transfer target portion appears. The peripheral part of the transferred adhesive layer forms a protruding edge part that protrudes from the peripheral part of the design.

  It should be noted that only the adhesive layer having the shape of the required pattern is formed on the release layer provided on the base sheet or separated by the hot-melt adhesive resin ink colored in the same or approximate color as the transfer target portion. It is also possible to form a transfer sheet by printing or the like on a base sheet having moldability, and to transfer the design to the transfer target portion using this transfer sheet.

  In this case, a pattern of the same or similar color as the transfer target portion is directly transferred by thermal transfer onto the transfer target portion, and the design has a design property due to a difference in refractive index of light from the transfer target portion. It will have.

Example 1
On the base sheet 10 (100 μm thick polyester film), a 180-mesh screen plate is made by engraving a shape in which the outer peripheral edge or inner and outer peripheral edges of each character is expanded by 2 mm rather than the pattern consisting of characters of “MATSUI” with a line width of 1 cm. Using the release treatment agent WAX IR (Wax, silicone, solvent, release resin containing polyamide resin: made by Matsui Dye Chemical Co., Ltd.), the shape is printed and dried to form the release layer 12 did.

  On the release layer 12, a pattern layer 14 was formed by printing the pattern with red ink using a 180-mesh screen plate made of a pattern made of characters “MATSUI” having a line width of 1 cm and drying it. The red ink used is 100 parts of M type clear ink (urethane resin, solvent, silicone antifoaming agent, clear ink containing silicon oxide: manufactured by Matsui Dye Chemical Co., Ltd.), M type color base red BR (red pigment, solvent) And 10 parts of a toner pigment containing a urethane resin and a dispersant: Matsui Dye Chemical Co., Ltd., and 5 parts of Coronate HL (Isocyanate curing agent: Nippon Polyurethane Co., Ltd.).

  On the design layer 14, using a 180-mesh screen plate made by making a shape in which the outer peripheral edge or inner / outer peripheral edge of each character is reduced by 0.2 mm from the design consisting of characters of “MATSUI” with a line width of 1 cm, The shape was printed with white hiding ink and dried to form a hiding layer 16. The white hiding ink used was 100 parts of M type white ink (hiding layer ink containing titanium oxide, urethane resin, solvent, silicone-based antifoaming agent) and 5 parts of coronate HL (isocyanate-based curing agent: manufactured by Nippon Polyurethane Co., Ltd.). Consists of.

  Subsequently, a 100-mesh screen plate is used in which the outer peripheral edge or inner / outer peripheral edge of each character is expanded by 0.7 mm from the pattern made of the characters “MATSUI” having a line width of 1 cm from the concealing layer 16. Then, the adhesive layer 18 was formed by printing with a black adhesive layer ink having a color similar to the color of the black cotton knit U, which is the transfer target (transfer target part), to a dry thickness of 100 μm and drying. . The peripheral edge portion 18 a of the adhesive layer 18 was formed on the release layer 12 provided on the base sheet 10 so as to surround the side portions of the design layer 14 and the masking layer 16.
