Description

  The present invention relates to a laminate film for covering (laminating) an image surface of a printed material having an image formed on a recording medium such as glossy recording paper for inkjet with a transfer film layer, and a transfer film layer using the laminate film. The present invention relates to a laminating method for producing a covered laminate print. More particularly, the present invention relates to a laminating film and a laminating method that can be laminated in a suitable state particularly for a printed matter in which an image is formed with a pigment ink.

  Conventionally, a laminate film is used for output printing by various recording methods such as an electrophotographic method and an ink jet recording method, and a resin layer laminated on a heat-resistant substrate constituting the film is thermocompression-bonded ( Laminate) and then peel off the heat-resistant substrate holding the resin layer, or obtain a finished print in the state without peeling, the image quality, weather resistance, and abrasion resistance of the printed matter. As a technique for improving image robustness such as the above, it has been widely used so far (see, for example, Patent Documents 1 and 2). The laminate film used in the above method has a resin layer formed on a heat-resistant substrate, and when the laminate film is thermocompression bonded to a printed material, the thermoplastic resin constituting the outermost layer is softened or melted. Thereby, the resin layer of the laminate film is transferred and fixed on the surface of the printed matter, and a laminated printed matter in which the surface protective layer (resin layer) is formed is obtained.

  In the above-described method, it is possible to form a thin surface protective layer of 20 μm or less on the image surface, and because the thermoplastic resin covers the image surface as the surface protective layer, The irregular reflection of light is prevented and, for example, a remarkable image quality improvement effect such as improvement in density and uniformity of glossiness can be obtained. Furthermore, since the protective layer formed on the surface of the printed material is a thin layer made of a resin, the obtained laminated printed material can be freely bent and the handling property is improved.

  Moreover, since the thing of suitable thickness can be selected as a heat resistant base material which comprises a laminate film, it can be thermocompression-bonded in the state which gave waist enough. Therefore, it is easy to handle the film in the laminating apparatus (such as setting a film), and the possibility of wrinkles entering the laminated thin film during the laminating process is reduced.

  However, in the conventional laminate printed matter as described above, for example, a heat resistant group after lamination is applied to a printed matter in which an image is formed on a glossy recording material (glossy medium) using pigment ink. When a laminate film of a type that peels off the material is used, there may be a case where the heat-resistant base material is poorly peeled. In general, the cause of peeling failure in the above-described form is that in a glossy medium, a pigment having a large particle diameter is only on the surface layer of the recording material, and the laminate film of the recording material and the pigment layer constituting the image. This is thought to be due to the extremely weak adhesion to the surface layer. That is, when laminating a printed material formed with an image with pigment ink, when the heat-resistant substrate is peeled off after lamination, the heat-resistant substrate is formed particularly in an image portion having a large amount of pigment. The pigment ink layer peels off from the surface layer of the recording material and does not peel in a good state between the substrate and the surface protective layer, resulting in poor peeling.

  Therefore, the object of the present invention is particularly when a laminate having a form in which an image is formed with a pigment ink, which is inferior in scratch resistance, and a heat-resistant substrate is peeled after lamination, is laminated. It does not cause poor peeling of the heat-resistant substrate after lamination, can be peeled in a good state, and by laminating, a good laminate printed matter with improved image characteristics and handling properties can be obtained. Another object of the present invention is to provide a laminate film capable of supplying a laminate print having both excellent releasability and image characteristics, and a good laminating method using the laminate film.

  The above object is achieved by the present invention described below. That is, the present invention comprises at least a heat-resistant substrate and a peelable transfer film layer provided on the heat-resistant substrate, and the transfer film layer is heat-pressed to produce a printed material. A laminate film configured to be transferred, wherein a print object to which the transfer film layer is transferred is formed by forming an image using pigment ink, and the transfer film layer is A laminate film comprising a surface protective layer and an adhesive layer, and the adhesive layer is made of a forming material containing 10 to 50% by mass of an ethylene-vinyl acetate copolymer resin with respect to the acrylic resin 100 It is.

  As a preferred embodiment of the laminate film according to the present invention, the above-mentioned printed matter to be laminated with the laminate film is a glossy recording paper for ink jet having an average surface glossiness of 10% (20 °) or more. An image is formed by using a pigment ink having a resin binder as a main component and a dispersion having a particle size of 10 to 150 nm, or the glossy recording paper for inkjet described above is porous on the surface. And an ink receiving layer having an average pore diameter of 1 to 100 nm.

  In another embodiment of the present invention, in the laminating method in which a transfer film layer constituting a laminate film is transferred to a printed material, and a laminate printed material in which the transfer film layer is fixed on the image surface is created, Using an image formed with pigment ink, the laminate film has a transfer film layer composed of a surface protective layer and an adhesive layer, and the adhesive layer is an ethylene-based resin with respect to the acrylic resin 100. A laminating method comprising using a forming material containing 10 to 50% by mass of a vinyl acetate copolymer resin.

  As a preferred embodiment of the laminating method according to the present invention, an acrylic resin binder is mainly used for an inkjet glossy recording paper having a porous ink receiving layer on a surface having an average pore diameter of 1 to 100 nm. Examples of the laminating method include a component in which an image is formed with a pigment ink having a dispersion having a particle diameter of 10 to 150 nm.

  According to the present invention, in a laminate film provided with a heat resistant substrate and a transfer film layer that can be peeled on the heat resistant substrate, and transferring the transfer film layer by thermocompression bonding onto the image surface of the printed material, The heat-resistant substrate can be peeled off in a good state, and as a result, when a printed material in which an image is formed with a pigment ink is laminated using the laminate film, the original good image characteristics and A good laminate print having maintained handleability is provided.

  Hereinafter, the present invention will be described in more detail with reference to preferred embodiments. First, prior to the description of the embodiment of the present invention, a transfer film layer (surface protection layer) that becomes a surface protective layer of a printed material when the laminated film is laminated on the printed material, which is important with respect to the effects obtained by the present invention. The fixing mechanism of the layer in the process in which the layer) is thermocompression bonded / transferred to the printed material will be described.

  In FIG. 1, reference numeral 1 denotes an unwinding reel of a roll of a laminate film 2 wound with a resin layer (transfer film layer) outside, and applies a back tension to the film 2. 3 is a heating roll, and 4 is a pressure roll that presses the film 2 against the heating roll. In FIG. 1, after the printed product P is inserted into the guide 11, the pressure roll 4 comes into pressure contact with the heating roll 3 and the heating roll starts to rotate. In the present invention, the transfer film layer is composed of a surface protective layer and an adhesive layer, and the roller pair 3 and 4 are used on the image side surface of the printed matter P with respect to the laminate film 2 via the surface protective layer. The adhesive layer adheres, and the transfer film layer is transferred and fixed. The end portion of the laminate film is cut by a cutter and is discharged out of the apparatus together with the printed matter. In the case of the laminate film according to the present invention, a finished laminate print can be obtained by peeling off the heat-resistant substrate holding the transfer film layer.

  Hereinafter, the laminate film according to the present invention used for obtaining a laminate printed material as described above will be described in detail. FIG. 2 is a schematic cross-sectional view showing the basic configuration of the laminate film according to the present invention. The illustrated laminate film 2 is configured by sequentially laminating a surface protective layer 2b and an adhesive layer 2c as a transfer film layer on a heat resistant substrate 2a.

  FIG. 3 is a schematic cross-sectional view of an example of an ink receiving paper (recording paper) to which a transfer film layer of the laminate film according to the present invention having the configuration shown in FIG. 2 is transferred. The recording paper shown in FIG. 3 is obtained by forming an ink receiving layer 100b on a base paper 100a, and an image is formed by applying pigment ink to the ink receiving layer 100b. A pigment ink layer 100c is laminated on the surface.

  Examples of prints suitable for laminating with the laminate film according to the present invention include the following. That is, the laminate film according to the present invention can provide a remarkable effect particularly when it is used for a printed material in which an image is formed with pigment ink by an inkjet recording method. More specifically, a pigment ink having a dispersion having a particle diameter of 10 to 150 nm mainly composed of an acrylic resin binder on an inkjet glossy recording paper having a surface average glossiness of 10% (20 °) or more. Examples of the printed material in which an image is formed using the. Further, when the glossy recording paper for ink jet has a porous ink receiving layer on the surface, and the average pore diameter of the ink receiving layer is 1 to 100 nm, a more remarkable effect is obtained. That is, as shown in FIG. 3, the printed matter composed of the combination of the recording paper and the pigment ink as described above is in a state where the pigment component of the pigment ink is on the surface of the glossy paper. Since the adhesion between the glossy paper surface and the image surface is extremely weak, the use of the laminate film according to the present invention, which can improve the peeling of the heat-resistant substrate, makes it more prominent. The effect can be achieved.

  FIG. 5 is a cross-sectional view schematically showing a printed matter in a completed state after the laminate film is bonded to the ink receiving paper (recording paper), and then the heat-resistant substrate 2a of the laminate film is peeled off.

  Next, the constituent material and manufacturing method of the laminate film according to the present invention will be described. First, the heat resistant substrate will be described. As the heat-resistant substrate, it is possible to stably maintain its shape without causing thermal deformation under the thermocompression bonding conditions when forming the surface protective layer of the laminate film on the surface of the printed material, Any material can be used as long as it can be easily peeled off when a transparent surface protective layer is formed on the ink receiving layer. Specific examples of such properties include, for example, polyethylene terephthalate, polyethylene terephthalate / isophthalate copolymer, polyester such as polybutylene terephthalate, polyolefin such as polypropylene, polyamide, polyimide resin, triacetyl cellulose, polyvinyl chloride, Examples thereof include films and sheets made of materials such as vinylidene chloride / vinyl chloride copolymer resin, acrylic resin, and polyether sulfone, and any of them can be used. The thickness of the heat-resistant substrate made of the above-described material is not particularly limited, but considering the ease of handling in the apparatus, the difficulty of wrinkles, and the economy, the thickness is about 15 μm to 200 μm. Are preferably used.

  The heat-resistant substrate used in the present invention may be subjected to a roughening treatment such as embossing or sandblasting or a roughening treatment with a resin layer containing powder particles on the surface on which the protective layer is formed. . By performing such a roughening treatment, the printed matter (laminated printed matter) on which the surface protective layer after lamination is formed becomes a semi-glossy or matte-like image. On the other hand, when the surface roughening treatment is not performed, after the laminate film is bonded to the printed matter (printed matter) and then the base film is peeled off, a glossy image having a protective layer is obtained.

  The laminate film according to the present invention includes a peelable transfer film layer formed on a heat-resistant substrate as described above, and the transfer film layer includes a surface protective layer and an adhesive layer. As the surface protective layer, when a laminate print is formed by laminating, the surface smoothness of the print screen (the surface on which the image is formed) is improved, and high glossiness is obtained. Even under harsh storage environments such as high temperature and low humidity and low temperature and low humidity, it is required that glossiness is reduced, film deterioration such as whitening, crack generation, etc. are reduced. From these points, as a material for forming the surface protective layer, it is preferable to use a resin having a high molecular weight and a high glass transition point as a main component. In particular, it is preferable to use a resin material whose molecular weight is 50,000 or more in terms of weight average molecular weight and whose glass transition point is 70 ° C. or more. Further, as a particularly preferred form, when the laminate print is placed in a high humidity environment, the resin that forms the surface protective layer absorbs moisture and swells, so that the image quality is deteriorated. It is mentioned to use this resin.

  As the resin for the surface protective layer based on the above characteristics, a resin such as an acrylic resin, a polyester resin, a melamine resin, a polyamide resin, a polyarylate resin, or a silicone resin can be used as the main component. Further, in order to particularly improve water resistance, solvent resistance, abrasion resistance, etc., thermosetting, ultraviolet curable, or electron beam curable resins may be used.

  Further, in image formation by the ink jet image recording method, dyes are often used, and the ultraviolet ray resistance is not sufficient. In such a case, the ultraviolet deterioration resistance can be improved by incorporating a compound having ultraviolet absorptivity into the resin. As a method for incorporating an ultraviolet absorbing compound into the resin, an ultraviolet absorbing compound such as benzotriazole may be used. There are a method of adding these ultraviolet absorbing compounds to the above-mentioned resin and a method of using them by copolymerizing with the above-mentioned resin component. Moreover, when using it adding to said resin, it is preferable from a durable surface to use a high molecular weight type ultraviolet-absorbing compound.

  The surface protective layer is formed on the heat-resistant substrate by applying a coating solution containing a solution or emulsion by roll coating, rod bar coating, spray coating, air knife coating or slot die coating. It can be done by drying. The thickness of the surface layer needs to be a film thickness that can prevent cracks due to stress, whereas if it is too thick, the performance of peeling along the periphery of the print is hindered. Therefore, the thickness of the surface layer needs to be selected from 1 to 20 μm.

  After forming the surface protective layer as described above, an adhesive layer mainly composed of a thermoplastic resin is formed thereon. In order to impart smoothness and abrasion resistance of the surface protective layer to the surface of the printed material, the adhesive layer softens and melts at the time of laminating, so that the surface of the printed material and the surface protective layer are in good condition by the adhesive layer. It is important to have a firm bond. As the thermoplastic resin for forming such an adhesive layer, a transparent acrylic resin having excellent optical characteristics is most suitable. Furthermore, the present invention is characterized in that a material obtained by mixing ethylene-vinyl acetate copolymer resin in the range of 10 to 50% by mass with the acrylic resin 100 is used as a material for forming the adhesive layer. As a result, when a laminate print is completed by peeling off the heat-resistant substrate, a good laminate print with improved image characteristics and handling properties can be obtained without impairing the optical characteristics and scratching in the image before lamination. The effect of the present invention is obtained.

  Since the ethylene-vinyl acetate copolymer resin used in the present invention has high crystallinity, it has high thermal responsiveness, low viscosity upon heat melting (viscosity at 120 ° C. is 10 cp or less), pigment ink layer and glossy paper fineness. It is easy to penetrate into the hole and high adhesion can be obtained. In addition, since the ethylene-vinyl acetate copolymer resin has both a hydrophilic group and a hydrophobic group in its structure, the image of the printed material has an acrylic resin binder as a main component and a particle diameter of 10 to 150 nm. In the case of being formed by a pigment ink having a dispersion of the above, it exhibits high adhesion to both the pigment ink containing an acrylic resin and the ink receiving layer as described later, and to the surface of the printed material. High adhesion can be achieved.

  In the formation of the adhesive layer, as in the case of forming the surface protective layer described above, for example, by various coating methods such as a roll coating method, a gravure coating method, a load bar coating method or a slot die coating method. It can be carried out. Further, at the time of coating, a dispersing agent, a surface tension adjusting agent, an antifoaming agent, an anti-blocking agent, and the like may be appropriately added to the coating liquid for forming the adhesive layer as necessary. It is desirable that the adhesive layer constituting the laminate film according to the present invention formed by the method as described above has a thickness of 10 μm or more. In this way, when the laminate film is transferred and fixed to obtain a laminate print, the unevenness on the surface of the print can be filled, light scattering can be suppressed, and the image density can be sufficiently increased.

  FIG. 5 is a schematic cross-sectional view of a laminate print after the laminate film according to the present invention having the above-described configuration is transferred and fixed. As described above, in the laminate film according to the present invention, the adhesive layer 2c easily penetrates into the pigment ink layer 100c, and the resin forming the adhesive layer has a lower viscosity at the time of fixing. Intermixing occurs between the pigment particles forming the and the adhesive layer material. Therefore, the adhesive effect of the adhesive layer 2c extends between the pigment ink layer 100c and the ink receiving layer 100b (see FIG. 5), and the completed laminate print adheres to the surface on which the image is formed. The layer exhibits strong adhesiveness, and good peeling performance is maintained between the surface protective layer and the heat-resistant substrate. On the other hand, when the conventional laminate film is used, as shown in FIG. 4, the above-mentioned mixing does not occur, so that good peeling is not performed when the heat-resistant substrate is peeled off. The image characteristics may be impaired.

  As described above, by using the laminate film having the structure of the present invention, the image surface of the printed matter is laminated to form a good transfer film layer (surface protective layer and adhesive layer) on the surface. be able to. Here, various recording media (such as recording paper) and various recording methods can be used for image formation of a printed matter. In particular, a recording medium and a recording method that are preferably used in the present invention include a recording medium in which an ink receiving layer is provided on a substrate, particularly an ink receiving layer mainly composed of porous inorganic particles. These include the formation of images using an inkjet recording method. The laminate film according to the present invention is effective for laminating a printed material on which an image is formed by a combination thereof. Examples of the porous inorganic particles that can be used for forming the ink receiving layer provided on the recording medium that can be suitably used in the present invention include silica, alumina, magnesium carbonate, silica-alumina mixed crystal, and silica-magnesium mixed crystal. .

  Further, when forming the ink receiving layer provided on the recording medium as described above, a binder (binder) can be used as the forming material, if necessary. As the binder, for example, water-soluble polymers or emulsions such as polyvinyl alcohol, polyvinyl acetate, and acrylic resins can be used. The compounding ratio of the porous inorganic particles mentioned above and these binders is, for example, 10 to 200 parts by mass, preferably 25 to 100 parts by mass of the binder with respect to 100 parts by mass of the porous inorganic particles. It can be appropriately selected from the range. Furthermore, various additives such as a dispersant, a fluorescent dye, a pH adjuster, a lubricant, and a surfactant can be added to the ink receiving layer as necessary. The thickness of the ink receiving layer is preferably selected from the range of 30 to 60 μm, for example.

  On the other hand, as a recording method in ink jet recording used when forming an image on the recording medium as described above, any method such as an electrostatic suction method, a method using a piezoelectric element, a method using a heating element, or the like is used. The recording method is not particularly limited. The ink used for inkjet recording may be any ink that can be applied to the inkjet recording system, such as an aqueous medium containing a coloring material such as a dye or pigment. In the present invention, a remarkable effect is obtained particularly when the image is formed using a pigment ink having an acrylic resin binder as a main component and a dispersion having a particle diameter of 10 to 150 nm. In the case of forming a color image, a full color image can be formed by subtractive color mixing using cyan, magenta, yellow, and, if necessary, black according to a conventional method.
