Water Transfer Paper for Dye Sublimation Printing {Waterslide Decal Paper for Dye Sublimation Thermal Transfer Printing}

The present invention, in order to solve the problems that can not invent the water transfer paper for dye-sublimation printing in the prior art, the water-soluble coating layer (2) excellent in printing cushioning property, peelability, and smoothness, printing on the transfer paper (1) that is a hygroscopic release paper Hydrophobic intermediate coating layer (3) excellent in cushioning properties, peeling properties, ink fixing properties, transfer film dimensional stability and adherend of the transfer object, smoothness, printing cushioning property, dye thermal transfer property, heat lubrication activity, UV protection, transfer film dimension stability By applying this excellent ink-receiving layer (4), it is the first environmentally friendly and economical new water transfer paper capable of transferring the image directly after printing without cumbersome and harmful protective coating process is to provide a dye-sublimation printing water transfer paper for the first time. In addition, by greatly improving the poor toner fusion, which is a problem of the conventional laser water and solvent water transfer paper, and the weak durability of the transfer film after solvent printing, digital printing that can be used for the dye sublimation printing water transfer paper for laser and solvent printers is also versatile. It is to provide a multipurpose transfer paper.

Recently, with the development of digital imaging technology, digital cameras and digital printers are becoming a necessity that can be easily used by the general public in each household. That is, the POD (Printing on Demand) method of outputting and storing digital images on photo papers is becoming a new paradigm. The types of digital printers include the most inexpensive and most popular inkjet printers, the dye sublimation printers with the highest resolution and high resolution photo quality, the laser printers with somewhat lower resolution but higher image durability, and the solvent printers with excellent printability on a wide range of materials. have.

With the trend of popularization of digital printers, there is an increasing demand for customized image transfer products that produce images by inserting images into various types of materials that cannot be directly printed. It is rising. In response to such a market environment, there is a need for an economical and processable transfer paper capable of separating images as easily as possible and transferring them to a desired transfer object.

In order to manufacture an image transfer product, stickers, waterslide decal paper, dye sublimation transfer paper, and heat transfer paper should be used. Sticker products are the most widely used products that can be used by simply attaching patterns such as images or logos to various uses after printing, but with relatively high film thickness (about 50 to 70 micrometers or more). Adhesion to the surface is incomplete, there is a fundamental disadvantage that the adhesive film is lifted from the edge portion over time (Delamination). Sublimation transfer paper or vinyl transfer paper is a method of transferring by heat, and heat press equipment is required, and transfer materials used are limited (such as tiles, fibers, and mugs). On the other hand, the water transfer paper is slow in production because it is manual, but it has the advantage that anyone can easily perform image transfer work without purchasing expensive equipment other than the printer owned by the user. have.

Conventional water transfer papers have been developed to be compatible with inkjet printers, laser printers, and solvent printers for each printing method, but commercially available water transfer papers that are compatible with the dye sublimation printer of the present invention have not been developed yet. The most widely used inkjet water transfer paper is an ink-receiving layer, so that a water-soluble resin is applied. Therefore, after inkjet printing, it is inconvenient to separate a transfer film into water after surface protection with a solvent-based coating agent. Since the protective coating process uses organic solvents that are harmful to the human body and serious in environmental pollution, users may avoid the work, and thus, the preference for inkjet water transfer paper may be greatly reduced. Therefore, most enterprise workers are urgently required to develop new water transfer papers (unprotected water transfer papers) that do not require this protective coating process.

The non-protective coating type water transfer paper is classified into two methods. First, the ink receiving layer of the above-mentioned inkjet water transfer paper is coated with a coating layer insoluble in water, and the second method is applied with a coating layer composed of hydrophobic resin. There is a way.

US Pat. No. 6,623,817, a technique according to the former method, is applied to the ink receiving layer of a water transfer paper by mixing a porous alumina sol and an aqueous binder, which impart water resistance and high color development, so that a protective coating is unnecessary. As well as waterproof, ink fast drying, high resolution (more than 2770dpi) color development is shown. However, this method is suitable for the purpose of printing and storing only images, such as inkjet photo paper, but there is a problem in using the transfer paper, in which the image is separated into a transfer film and attached to a transfer object. That is, the alumina sol introduced by the water resistance effect is very hard and inflexible in the state of coating, so that the attached transfer film is easily curled from the edges over time, or the transfer film is easily broken during operation. There are various problems to use as a water transfer paper such as broken. As the latter method, dye sublimation printers, laser printers, and solvent printers are known which impart water resistance by using a hydrophobic resin instead of a water-soluble resin as a composition of the ink receiving layer, and which have a different printing method from the inkjet printing described above.

It is an object of the present invention to provide a water transfer paper for dye-sublimation printing which has not been developed so far as the above-mentioned unprotected coated water transfer paper. In addition, the water transfer paper for dye-sublimation printing of the present invention is excellent in print compatibility with other printing methods such as laser and solvent printers, which dramatically improves the durability of toner fusion, solvent ink fixing, and transfer film, which are problems in conventional laser and solvent water transfer paper. Therefore, it is to provide a multi-purpose transfer paper for digital printing, which has excellent print compatibility for dye-sublimation printers, laser printers, and solvent printers with one type of water transfer paper.

 Conventional laser water transfer papers differ in thermal energy and pressure conditions of OPC drums according to printer specifications, and currently available water transfer papers lack compatibility with all types of printers on the market. In general, less than about 50% of the market is used in a limited situation. Even printers of the same manufacturer have a variety of problems, such as high printing speed, due to a high thermal energy imposed on the drum, resulting in poor adhesion of toner to the water transfer paper. Therefore, there is a need for the development of laser water transfer paper having more stable toner fusion that can be compatible with all commercially available laser printer models. Korean Patent No. 10-04666835 provides a method of printing a laser printer toner on a conventional water transfer paper and sintering at a melting point at which a pigment glaze is melted through an overcoating process, thereby producing a pattern on ceramics or the like. However, this method is not compatible with a general-purpose laser printer aimed at by the present invention, and furthermore, there is a problem that a high temperature sintering process (about 800 degrees or more) is required.

Korean Patent No. 10-0684042 discloses a water transfer paper for printing oil-based ink that does not require a protective coating by combining a binder such as alkyd resin, dioxyl phthalate, nitrocellulose, and the like into an oil-based resin layer. However, this method is useful in a method of printing by spraying non-contact ink such as a solvent printer, but in a printer printed by a high temperature and compression method such as in a dye-sublimation printer and a laser printer, which is the object of the present invention, the heat-resistant lubricity of the known oil-based resin layer is known. There is a problem that it is difficult to actually use such that the water transfer paper may be stuck to the heat head or the drum during printing due to this very shortage.

Dye-sublimation printing is full color high resolution that is comparable to the conventional silver-halide printing and almost no noise during printing, and it has excellent printing reliability. In addition to the production of membership cards, it is widely used for high-resolution digital image output for defense, medical care, and analysis. In this printing method, an ink ribbon is formed by applying a color ink solution formed of a sublimable disperse dye and a transparent overlay coating solution on a polyester film of a thin film by a gravure coating method. When a thermal print head heats more than about 200 degrees on an ink receiving media called paper, the ink ribbon is sublimed and transferred to a receiving surface. That is, when the dye is transferred onto the ink receiving layer in continuous tone according to the heat energy imposed by the heat head, a full color high resolution image is formed, and the overlay layer is transferred to the thin transparent film by the heat head on the image to sunlight. It is to provide a printed layer that is stable in the long term against moisture, scratches, and the like. At this time, the resolution of the printing layer depends on the sublimation transfer efficiency of the dye, and the efficiency greatly depends on the smoothness and cushioning properties of the ink resin paper.

As a base fabric of conventional dye-sublimation ink resin paper, a fabric having excellent smoothness and cushioning properties, such as synthetic paper, polyester, polyester sulfone, polyamide, and release paper co-extruded with white pigment dispersion polyethylene, is used. do. However, unlike the conventional sublimation ink resin paper which only needs to print an image, the water transfer paper for dye-sublimation printing of the present invention has to be separated into a transfer film in water, so the base fabric mentioned above cannot be used basically. . That is, only a transfer source that is a release paper having excellent hygroscopicity can be used as a water transfer paper. However, although the transfer base is suitable as a base material for inkjet, laser, and solvent printing water transfer papers, the physical properties such as surface smoothness and print cushioning properties are not suitable for use as water transfer papers for dye-sublimation printing. As a design, there are various problems that cannot satisfy the requirements of water transfer paper such as image color development, print runability, and water peelability.

As described above, there have been no cases of domestic and international application of a dye transfer paper to a dye sublimation printer. Therefore, in the case of a coating composition applied to a conventional dye sublimation ink resin, US patent US20110052842 applies a composition composed of 20-500 inorganic nanoparticles and has a general dye sublimation ink having sufficient heat-lubrication activity even under high temperature heat head conditions. Known for the receiving place, there is a problem in lack of cushioning, water peeling, etc. to use as a water transfer paper. The composition of the conventional ink-receiving layer and the intermediate layer known from Korean Patent No. 10-0556093 does not have cushioning, smoothness, and heat-lubricating activity as in the present invention, and also does not have a water-soluble coating layer that causes water peeling. I have a problem. In addition, there are inventions related to dye-sublimation ink resin papers in Korean Patent No. 10-0199564, Korean Patent No. 10-0782356, etc., all of which are known for compositions and coating layer structures related to conventional ink resin papers different from water transfer papers.

In order to solve the problem of the transfer paper and to use for dye-sublimation printing, the present invention provides a water-soluble coating layer (2) having excellent peelability and print cushioning property on one side of the transfer paper, and smoothness, print cushioning property, and peelability on the coating layer (2). , Hydrophobic intermediate coating layer (3) excellent in ink fixability, transfer film dimensional stability and adherend of transfer object, smoothness, printing cushioning, dye thermal transfer, heat-lubricating activity, printing cushioning, UV protection, transfer film on the coating layer (3) Through constant experiments for the optimization of the above-mentioned physical properties such as the composition of the ink-receiving layer 4 having excellent durability and the control of the coating structure composed of the respective compositions, the coating composition and the coating structure suitable for dye-sublimation printing water transfer paper are found and lead to the present invention. It became.

Furthermore, the present invention finds a coating composition and coating structure having a toner fusion property, solvent printability and durability of transfer film, and UV protection significantly improved than conventional laser and solvent water transfer papers, and a dye sublimation printer as well as a laser and a sublimation printer. Invented a versatile transfer paper for digital printing that is compatible with all solvent printers.

An object of the present invention is to first invent a water transfer paper compatible with a dye-sublimation printer, which is an environmentally friendly printing method, which does not require serious protective coating work, which is harmful to humans and environmental pollution, used in the above-described conventional inkjet water transfer paper. In addition, it is to significantly improve the problems of conventional laser and solvent printing water transfer paper, to provide a multi-purpose transfer paper for digital printing that is compatible with various types of printers economical and convenient image processing.

The present invention is to solve the problem of the transfer paper as a hygroscopic release paper and to use for dye-sublimation printing, water-soluble coating layer 2 excellent in peelability, printing cushioning property on one side of the transfer paper, smoothness, printing cushioning property, Hydrophobic intermediate coating layer (3) having excellent peelability, ink fixability, transfer film dimensional stability, and adherend of a transfer object, smoothness, printing cushioning property, dye thermal transfer property, heat lubrication activity, printing cushioning property, UV blocking property, The present invention was found to find a coating composition and coating structure suitable for dye-sublimation printing water transfer paper through constant experiments for the optimization of the above-mentioned physical properties, such as the composition of the ink receiving layer 4 having excellent transfer film durability and the control of the coating structure composed of each composition. Came to.

Furthermore, the present invention finds a coating composition and coating structure having a toner fusion property, solvent printability and durability of transfer film, and UV protection significantly improved than conventional laser and solvent water transfer papers, and a dye sublimation printer as well as a laser and a sublimation printer. Invented a versatile transfer paper for digital printing that is compatible with all solvent printers.

As can be seen from the above description, the water-soluble coating layer, the hydrophobic intermediate coating layer and the ink receiving layer composition of the main coating layer of the present invention is excellent in the effect of producing a water transfer paper for dye-sublimation printing, and also limited printer model that is a disadvantage of the conventional laser water transfer paper It is effective in drastically improving the weakness of the toner fusion property and weak transfer film, which is a disadvantage of water transfer paper for solvent.

In addition, the present invention is to give a composition having excellent hot melt adhesive to the hydrophobic intermediate coating layer and the ink receiving layer, a variety of uses that can easily thermally transfer the digital image to the transfer object such as fibers with a ramimina heat press Can also be used as

The present invention forms a water-soluble coating layer (2) with a water-soluble resin composition having printing cushioning property and peeling property on one side of the transfer paper, and the smoothness, printing cushioning property, peeling property, ink fixing property, transfer film dimensions on the water-soluble coating layer (2). A hydrophobic intermediate coating layer (3) is formed of a hydrophobic resin composition having excellent stability and adhesion of a transfer object, and on the hydrophobic intermediate coating layer (3), smoothness, print cushioning property, dye thermal transfer property, heat lubrication activity, UV blocking property, toner fusion property, Provided is a water transfer paper for dye-sublimation printing, which is formed by applying the ink receiving layer (4) with a hydrophobic resin composition excellent in solvent ink absorption and transfer film durability. Still another object of the present invention is to provide a multi-purpose transfer paper for digital printing, which has excellent print compatibility with other printing methods such as laser printers and solvent printers by using the above-mentioned dye-sublimation printing water transfer paper.

1 shows a step of producing a water transfer paper for dye-sublimation printing according to the present invention, which will be described in more detail with reference to the drawings.

1, the composition of the water-soluble coating layer (2) of the present invention is a star binder, gelatin, sorbitol, polyvinyl alcohol, polyacrylic acid, polyvinylpyrrolidone, water-soluble poly

A single or two or more kinds of water-soluble resins such as urethanes, water-soluble polyesters and cellulose derivatives are mixed, and solid particle additives such as natural or synthetic waxes, talc, titanium oxide, and silica having excellent cushioning properties are used alone or in two or more kinds. In order to mix and improve peelability, liquid additives, such as surfactant, an aqueous slip agent, ethylene glycol, a plasticizer, are mixed individually or in 2 or more types, and an aqueous coating layer composition is comprised. More specifically, 5 to 20% of main binder, 0.5 to 10% of solid particle additive, 0.1 to 3% of liquid additive, 20 to 40% of isopropyl alcohol, 10 to 20% of ethanol, and 20 to 40% of water The coating solution is applied to one side of the transfer base using a conventional thin film coating technique (gravure, comma, knife, bar coating, roll coating, etc.), and the coating thickness is in the range of 0.1 μm to 25 μm, more preferably 1 μm to 15 μm. Shall be. If the coating thickness is 0.1μm or less, the smoothness and cushioning property are reduced, and the color development degree is greatly reduced when dye-sublimation printing. If the coating thickness is 25μm or more, the adhesion by water-soluble resin is too high and the water peeling property is difficult, making water transfer work difficult. Lose. The water-soluble coating layer (2) is a water transfer paper for dye-sublimation printing of the present invention to function as a water transfer paper, when the water-printed paper actually printed about 30 seconds in the water, the water-soluble coating layer (1) to the back of the transfer paper which is hygroscopic It is easily dissolved by water absorbed from the surface, and at the same time, the surface of the transfer paper 1 and the transfer film (3 + 4 + 5 + 6) slide like water sliding. In addition to the above method, any known method may be used as long as the smoothness, cushioning properties, and peelability effects are the same.

In FIG. 1, the hydrophobic intermediate coating layer 3 absorbs not only the peelability of the transfer film 3 + 4 + 5 + 6 separated from the water-soluble coating layer 2, but also the cushion property during dye sublimation printing, and the ink receiving layer 4. It controls ink fixation, penetrating smoothness of transfer paper, UV protection of transfer film, dimensional stability of transfer film, and adhesion of transfer film to transfer object to develop effective ink. . The hydrophobic intermediate coating layer 3 is a single binder or a mixture of two or more kinds of thermoplastic resins such as polyester, polyurethane, polyvinyl butyral, vinyl chloride copolymer, acrylic resin, polystyrene copolymer, polycarbonate and the like Excellent natural or synthetic waxes, talc, titanium oxide, silica, alumina and other solid particle additives are mixed alone or in combination of two or more, and a silicone curing agent is added to form a hydrophobic intermediate coating (3) layer composition.

More specifically, 10 to 40% of the main binder, 0.5 to 20% of the solid particle additive, 0.1 to 2% of the silicone curing agent, 20 to 40% of the toluene, 20 to 40% of the methyl ethyl ketone, and 20 to 40% of the ethyl acetate are added. The coating solution is applied onto the water-soluble coating layer 2 using a conventional thin film coating technique (gravure, comma, knife, bar coating, roll coating, etc.), and the coating thickness is 5 μm to 40 μm, more preferably 15 μm to 30 μm. It is a range. If the coating thickness is 5 μm or less, the smoothness and cushioning properties are reduced, the dye sublimation printing color development is greatly reduced, the color development is also reduced by reducing solvent ink adhesion. In addition, if the transfer film becomes too thin and the dimensional stability is poor, workability is greatly degraded such as the transfer film is easily folded or stretched during water transfer processing. If the coating thickness is 30μm or more, the transfer film is too stiff (Stiff) has a drawback (Wrapping) can be smoothly wrapped around the curved surface or the edge of the transfer (Wrapping) is reduced, there is a disadvantage that the water transfer workability is inferior.

On the other hand, if the content of the solid particle additive is 0.5% or less by weight ratio, the peelability is reduced and the water transfer peelability is lowered. If the content is 20% or more by weight ratio, the water peelability is increased while the adhesion to the transfer object is increased. Has the problem of being reduced. If the silicone curing agent is 0.1% or less by weight ratio, the dimensional stability of the transfer film is lowered and water transfer workability is lowered. If the content is 2% or more by weight ratio, the interface adhesion between the hydrophobic intermediate coating layer 3 and the water-soluble coating layer 2 is increased. The water peelability is lowered. In addition to the above method, any known method may be used as long as the properties of the hydrophobic intermediate coating layer in accordance with the object of the present invention are expressed.

In FIG. 1, the ink receiving layer 4 is a top coating layer for the dye sublimation printing to proceed normally, and the printing runs smoothly between the coating layer and the coating layer of the ink ribbon under the high temperature head of about 200 degrees or more. Excellent heat lubrication activity is required. In addition, it is required to have excellent dye absorption and UV protection, and the disadvantage that the printed dye gradually discolors over time (that is, reverse sublimation transfer phenomenon) should be minimized, and the printing layer 5 formed on the ink receiving layer 4 should be minimized. Interfacial adhesion with the overlay layer 6 to be protected must be excellent in order to provide the print layer with sufficient durability to withstand sunlight, moisture, and scratches.

Another feature of the ink-receiving layer 4 of the water transfer paper for dye-sublimation printing in the present invention is that when applied to a laser printer, it provides compatible toner fusion properties to a wider range of printers than conventional laser water transfer paper. Figure 4 shows a cross-section printed toner on a laser water transfer paper, dye sublimation and solvent water transfer paper sublimation dye and liquid ink is absorbed into the ink receiving layer 4 penetrates to the hydrophobic intermediate coating layer (3) to form a printed layer On the other hand, in the case of toner printing, when the toner composition melted by the OPC drum is fused to the surface of the ink receiving layer 4 and solidified at a room temperature, the toner printing layer 5 is formed. Toner fusion refers to how effectively the toner composition is fused to the ink receiving layer when the OPC drum melts the toner particles at a high temperature and is fused to the surface of the water transfer paper. It also provides excellent effects in the process of heat welding. In particular, when the toner fusion property is excellent, there is no peeling of the fused toner at the time of water transfer processing, so that the workability as well as the image transfer product quality are greatly improved. In addition, for special applications requiring thinner and more flexible transfer films (when transferring images to candles or model airplanes), as shown in FIG. 5, the hydrophobic intermediate coating layer 3 may be omitted, and the laser water transfer paper may be manufactured using only the ink receiving layer 4. have.

On the other hand, in solvent water transfer applications, as shown in FIG. 6, the ink absorbed in the ink receiving layer sufficiently penetrates to the thick hydrophobic intermediate coating layer 3 to provide excellent color development. However, since the absorbed ink has a kind of plasticizer effect, the thick transfer film becomes softened, so that the transfer film may be folded or curled during actual water transfer processing. It is important. In addition, after the image transfer product is manufactured, it is necessary to appropriately contain a thermosetting reactive material in the coating composition so that the scratch resistance of the transfer film is greatly improved by heat treatment or the like.

In the present invention, the ink-receiving layer 4 is a sole binder or a thermoplastic resin such as polyurethane, cellulose resin, polyvinyl butyral, polyester, vinyl chloride copolymer, acrylic resin, polystyrene copolymer, polystyrene, polycarbonate or the like. Mixing two or more kinds, solid particle additives such as talc, titanium oxide, natural or synthetic waxes, alumina, silica, etc. having excellent cushioning properties and heat-resistant lubricating properties, alone or in combination of two or more kinds thereof, UV stabilizers, reactive silicone resins, and poly Isocyanate curing agent is mixed to form an ink receiving layer composition. More specifically, the weight ratio of the main binder 5 to 20%, solid particle additive 0.2 to 10%, silicone resin 0.2 to 2%, UV stabilizer 0.3 to 3% polyisocyanate curing agent 0.1 to 1%, toluene 15 to 35%, methyl Ethyl ketone 30-45, ethyl acetate 15-30% are blended, and the coating solution is applied on the hydrophobic intermediate coating layer 3 by conventional thin film coating techniques (gravure, comma, knife, bar coating, roll coating, etc.). The coating thickness is 1 μm to 20 μm, more preferably 5 μm to 15 μm. If the coating thickness is 5 μm or less, the thermal lubrication activity is lowered and the ink ribbon is fused or the toner is fused at the time of dye sublimation and laser printing, resulting in poor print runability. If the coating thickness is 15 μm or more, the heat resistance is increased, which is advantageous for dye-sublimation printing, but the toner fusion property is lowered during laser printing.

On the other hand, if the solid particle additive content is less than 0.2% by weight ratio, the heat-resistant lubrication activity is lowered, and if the content is more than 10% by weight ratio, the surface is roughened and surface smoothness is reduced to reduce the printing color development. When the content of the silicone resin is 0.2% or less by weight ratio, the thermal lubrication activity is decreased, so that the dye sublimation printability and laser toner fusion are deteriorated, while when the content is 2% or more by weight ratio, the surface releasability of the ink receiving layer is increased and the dye sublimation printing is performed. There is a problem that the ink ribbon is slipped finely and the focus of the image is distorted. If the content of polyisocyanate-based curing agent is 0.1% or less by weight ratio, the thermal lubrication activity is decreased, and dye-sublimation printability and laser toner fusion resistance are lowered. If the content is 1% or more by weight ratio, heat resistance is increased and toner fusion resistance is reduced. Due to the stiff nature of the film, there is a problem that the lapping property of the transfer film is deteriorated. In addition to the above methods, any known method may be used as long as the properties of the ink receiving layer meeting the object of the present invention are expressed.
