Description

  The present invention relates to a hard coat layer transfer foil, and more specifically, imparts excellent durability such as friction resistance and solvent resistance to a medium having a transfer image and the like, and when transferring to a medium, the foil breaks. The present invention relates to a hard coat layer transfer foil that is excellent in transferability.

  In the present specification, “ratio”, “part”, “%” and the like indicating the composition are based on mass unless otherwise specified, and the “/” mark indicates that they are integrally laminated.

  (Main use) Examples of the use of the medium in which the hard coat layer transfer foil of the present invention is used to transfer the hard coat layer to the support include cards such as credit cards, cash cards, ID cards, passports, membership cards, etc. In addition, it can be suitably used for a medium that requires security, such as a medium in which information for personal identification such as a photo of a sublimation dye is recorded, such as a booklet such as a license or a bankbook. However, there is no particular limitation as long as the application requires durability on the surface.

(Background Art) The thermal transfer method has come to be widely used as a simple printing method. In these thermal transfer methods, various images are easily formed, and therefore, the thermal transfer method is used to create a printed material that requires a relatively small number of prints, for example, an ID card such as an identification card. When a color image is preferable, such as a face photograph, a large number of colored thermal transfer layers of, for example, yellow, magenta, and cyan (and black if necessary) are repeatedly provided in sequence on a continuous base film. A thermal transfer method using a long thermal transfer film has been performed. Such thermal transfer films can be broadly classified as a so-called melt transfer type thermal transfer film in which the thermal transfer layer is softened by heating and thermally transferred to an imaged thermal transfer material, and the dye in the thermal transfer layer is sublimated by heating ( It is roughly classified into a so-called sublimation type thermal transfer film in which only the dye is thermally transferred onto the thermal transfer material in an image form by heat transfer.
When creating ID cards such as identification cards with the above thermal transfer film, it is easy to form images such as letters and numbers in the case of a melt transfer type thermal transfer film, but these images are durable. In particular, there is a drawback that the friction resistance is inferior. On the other hand, in the case of a sublimation transfer type thermal transfer film, a gradation image such as a face photograph can be formed, but unlike a normal printing ink, the formed image has no vehicle, so There exists a problem that it is inferior to durability, such as a weather resistance and friction resistance.
As a method for solving the above problems, many methods for transferring a protective layer (corresponding to the hard coat layer of the present invention) such as a transparent resin layer and a cured resin layer have been proposed. However, since the image exists on the outermost surface, the durability deteriorates over time due to mechanical friction, solvent, other chemicals or environmental influences over a long period of time, and in extremely harsh environments. Gas station cards and construction site cards that are used, and entrance / exit cards that do not expire or that repeatedly enter and leave a number of security-controlled rooms such as financial institutions It has increased, and sufficient durability has not yet been obtained. However, when the protective layer is thickened, the foil breakage is remarkably deteriorated.
Therefore, the hard coat layer (protective layer) transfer foil has good transparency even when used in extremely harsh environments, has no expiration date, is used for a long time, and / or is repeatedly used many times. It is required that the image is protected from general friction and abrasion, is excellent in durability not to be damaged, and has a good foil breakage and can be transferred at one time.

(Prior Art) Conventionally, in order to enhance the durability such as the wearability of the surface of a face photograph image of an employee ID card, at least a release layer, a cured layer of a specific resin, an optical change element layer are provided from a support having a release layer. It is known that an intermediate layer and an adhesive layer are transferred onto a facial photograph (for example, see Patent Document 1).
The present applicant also applies a base film / transparent resin layer / polar group as a protective layer transfer film that can impart various durability such as light resistance, friction resistance, plasticizer resistance, and chemical resistance to thermal transfer images. A laminated body in which a plasticizer-resistant resin layer / a heat-adhesive resin layer composed of an acrylic copolymer resin containing a component having an antistatic property and a resin having an antistatic property is laminated in this order (for example, Patent Document 2).
Further, the present applicant has made a substrate film / transparent resin layer (releasable) / resistant as a protective layer transfer film in which various durability of the thermal transfer image, in particular, chemical resistance, light resistance and weather resistance are maintained for a long period of time. A material provided with at least one of a chemical property-imparting layer, an ultraviolet blocking layer and a security layer is disclosed (for example, see Patent Document 3).
However, any of the above has the problem that the durability of the image surface is still insufficient under severe use conditions.

FIG. 1 is a cross-sectional view of a hard coat layer transfer foil showing one embodiment of the present invention.
FIG. 2 is a cross-sectional view showing a state where an image is protected by transferring to a support using the hard coat layer transfer foil of the present invention.

  (Hard Coat Layer Transfer Foil) As shown in FIG. 1, the hard coat layer transfer foil 10 of the present invention has at least a release layer 13 and a hard coat layer 15 on one surface of the substrate 11 and the substrate 11. The ultraviolet absorbing layer 21 and the adhesive layer 19 are laminated as necessary, and the substrate 11 / release layer 13 / hard coat layer 15 / adhesive layer 19 are essential. The hard coat layer 15 includes a material to be described later and polyethylene wax, and the problem can be solved by preferably controlling the addition ratio of the polyethylene wax and the thickness of the hard coat layer 15. FIG. 2 shows the hard coat layer transfer foil 10 of the present invention, and the hard coat layer 15, the ultraviolet absorbing layer 21 (if necessary), and the adhesive layer 19 are applied to the surface of the image 105 formed on the support 101. The transferred state is shown. The hard coat layer 15 is positioned on the outermost surface to protect the image and enhance durability.

(Substrate) As the substrate 11, various materials can be applied depending on the use as long as the substrate 11 has heat resistance, mechanical strength, mechanical strength to withstand manufacturing, solvent resistance, and the like. For example, polyester resins such as polyethylene terephthalate and polyethylene naphthalate, polyamide resins such as nylon 6, polyolefin resins such as polypropylene and polynorbornene, vinyl resins such as polyvinyl chloride, and acrylic resins such as polymethyl methacrylate And styrene resins such as polycarbonate and high impact polystyrene, cellulose films such as cellophane and cellulose acetate, and imide resins such as polyimide.
Preferably, in terms of heat resistance and mechanical strength, polyethylene terephthalate is most suitable for a film of a polyester resin such as polyethylene terephthalate, polybutylene terephthalate, and polyethylene naphthalate. The thickness of the substrate is usually about 2.5 to 50 μm, but 4 to 25 μm is preferable in terms of transferability.

  The substrate may be a copolymer resin containing these resins as a main component, a mixture (including an alloy), or a laminate composed of a plurality of layers. The substrate may be a stretched film or an unstretched film, but a film stretched in a uniaxial direction or a biaxial direction is preferable for the purpose of improving the strength. The substrate is used as a film, sheet or board formed of at least one layer of these resins. Prior to application, the substrate is subjected to corona discharge treatment, plasma treatment, ozone treatment, flame treatment, primer (also called an anchor coat, adhesion promoter, or easy adhesive) application treatment, pre-heat treatment, dust removal treatment. Alternatively, easy adhesion treatment such as vapor deposition treatment or alkali treatment may be performed. Moreover, you may add additives, such as a filler, a plasticizer, a coloring agent, and an antistatic agent, as needed.

  (Release layer) The release layer 13 usually includes a release resin, a resin containing a release agent, a curable resin that is cross-linked by ionizing radiation, etc. In the present invention, a melamine resin is used, which will be described later. By combining with the hard coat layer 15 to be peeled off, the separation between the release layer 13 and the hard coat layer 15 is stabilized, and the foil breakage during transfer can be remarkably improved.

  The release layer 13 is formed by dispersing or dissolving the resin in a solvent, applying and drying the resin by a known coating method such as roll coating or gravure coating, and baking at a temperature of about 150 ° C to 200 ° C. The thickness of the release layer 13 is usually about 0.01 μm to 5.0 μm, preferably about 0.5 μm to 3.0 μm.

  (Hard Coat Layer) The hard coat layer 15 contains a cured product of ionizing radiation curable resin and polyethylene wax. The ionizing radiation curable resin is preferably (1) an isocyanate having three or more isocyanate groups in the molecule, and (2) at least one hydroxyl group and at least two (meth) acryloyloxy groups in the molecule. Using an ionizing radiation curable resin containing a urethane (meth) acrylate oligomer which is a reaction product of a polyfunctional (meth) acrylate having a polyhydric alcohol having at least two hydroxyl groups in the molecule, or (3) A wax may be included, applied, dried, and cured with ionizing radiation.

  The ionizing radiation curable resin containing the urethane (meth) acrylate oligomer (referred to herein as the ionizing radiation curable resin composition M) is a cured ionizing radiation curable resin containing the urethane (meth) acrylate oligomer. Examples thereof include photocurable resins disclosed in Japanese Patent Application Laid-Open No. 2001-329031.

  (Polyethylene wax) Polyethylene wax includes polyethylene resin particles and beads, and is preferably spherical beads. However, when polyethylene wax is added, the foil breakage is reduced, so the amount added is about 0.01 to 10 parts by weight, preferably 0.1 to 5 parts by weight, with respect to 100 parts by weight of ionizing radiation curable resin. And

  (Formation of hard coat layer) The hard coat layer 15 is formed by adding polyethylene wax, photopolymerization initiator, plasticizer, stabilizer, surfactant, etc. to the above-mentioned ionizing radiation curable resin, to the solvent. It may be dispersed or dissolved, applied by a known coating method such as roll coating, gravure coating, comma coating or die coating, dried, and reacted (cured) with ionizing radiation. Further, when the hard coat layer 15 is thick, it may be divided into a plurality of times.

  (Thickness of hard coat layer) The thickness of the hard coat layer 15 is usually about 1 to 10 μm, but in the present invention, it is used in a very severe environment, has no expiration date, or is used for a long time. In order to protect the image from solvent and mechanical friction and wear, especially scratching, and to give durability not easily damaged even in repeated use many times, etc., preferably 10 μm or more, preferably 15 μm or more. . The upper limit is not particularly limited, but is about 30 μm or less in view of price and foil breakability. The hard coat layer 15 has a thickness of 10 μm or more, preferably 15 μm or more, so that the durability is enhanced, use in extremely harsh environments, no expiration date, long-term use, and / or many A hard coat layer transfer foil capable of protecting an image from a chemical mechanical external force even when used repeatedly is obtained.

  Thus, by using melamine-based resin as the release layer 13 and at least a cured product of the “ionizing radiation curable resin composition M” and the polyethylene wax as the hard coat layer 15, the following functions and effects can be achieved. It can be done. (1) Since the hard coat layer coating film in a coated state before ionizing radiation curing is not sticky in a finger-dried state and can be wound up without blocking, roll-to-roll processing is possible, manufacturing is easy, and cost is also low. Low. (2) The hard coat layer 15 is easily broken and the foil breakability can be remarkably improved. (3) After the transfer, it is positioned on the outermost surface of the support having an image, and develops durability from a mechanical and / or chemical environment.

  (Ultraviolet absorbing layer) The ultraviolet absorbing layer 21 may be provided between the hard coat layer 15 and the adhesive layer 19 as necessary, and other layers may be provided as necessary. By providing the ultraviolet absorbing layer 21, images such as facial photographs formed using sublimation transfer type ink ribbons are mainly composed of dyes with poor light resistance. Can be maintained. As the ultraviolet absorbing layer 21, a composition containing an ultraviolet absorber such as benzotriazoles, benzophenones, substituted oxanilides, cyanoacrylates, or triaryltriazines in a binder may be used. Add a polymerization initiator, plasticizer, stabilizer, surfactant, etc., disperse or dissolve in a solvent, and apply and dry by a known coating method such as roll coating, gravure coating, comma coating, die coating, or drying, Alternatively, it may be aged (cured) after drying or reacted (cured) with ionizing radiation.

  (Adhesive layer) As the adhesive layer 19, a heat-sensitive adhesive that melts or softens when heated and exhibits an adhesive effect can be applied. Specifically, a vinyl chloride resin, a vinyl acetate resin, or vinyl chloride. Examples thereof include vinyl acetate copolymer resins, acrylic resins, and polyester resins. The adhesive layer 19 preferably contains a filler such as microsilica in terms of the ability to break the foil. The resin of the adhesive layer 19 is preferably one having a melting point of 60 to 95 ° C. that melts and adheres at a low temperature of about 95 ° C. and solidifies and adheres at about 60 ° C. When the melting point is less than the above range, the adhesion to the support is insufficient, and the temperature at which the formed image is used is limited. On the other hand, if the melting point exceeds the above range, the transferability becomes insufficient by heating with a thermal head, the foil breakability of the hard coat layer is lowered, and transfer with good resolution becomes difficult. The material resin is dissolved or dispersed in a solvent, an additive such as a pigment is added as appropriate, and the layer is applied and dried by a known method such as roll coating, gravure coating, or comma coating, and a layer having a thickness of 1 to 30 μm Get.

  (Transfer) Using the hard coat layer transfer foil 10 of the present invention thus obtained, as shown in FIG. 2, the hard coat layer 15, the ultraviolet absorbing layer 21 (if necessary), and the adhesive layer 19 are Then, the image is transferred to the surface of the image 105 formed on the support 101. The hard coat layer 15 is located on the outermost surface, and both protect the image and enhance the durability. Although peeling occurs between the release layer 13 and the hard coat layer 15 at the time of transfer, a part of the release layer 13 may be transferred to the hard coat layer 15 within the scope of the present invention.

  (Transfer method) As a method for forming the support 101, a known transfer method may be used. For example, hot stamping by hot stamping (foil stamping), whole surface or stripe transfer by a heat roll, thermal by a thermal head (thermal printing head). A known method such as a printer (also referred to as a thermal transfer printer) can be applied. Any shape such as a spot shape, letters, numbers, and illustrations may be transferred. A thermal printer that can continuously operate different shapes or print on demand is preferable.

  In addition, as described in the background art, sufficient durability has not been obtained yet in use in an extremely severe environment, a long-term expiration date, and / or repeated use many times. The protective layer (the hard coat layer of the present invention) may be thickened. However, since the foil breakage is remarkably deteriorated when the thickness is increased, the protective layer was transferred twice. According to the hard coat layer transfer foil 10 of the present invention, the hard coat layer 15 having a high image protection property can be transferred at one time even if the thickness is large, with good peelability and foil breakage. The hard coat layer 15 exists on the surface of the image, protects it from mechanical and chemical damage for a long period of time, and is used in extremely harsh environments. It can also be suitably used for long-term entrance / exit cards, point cards, entrance / exit cards that repeatedly enter and exit a number of security-controlled rooms such as financial institutions.

  (Support) The support 101 is not particularly limited. For example, natural fiber paper, coated paper, tracing paper, plastic film that is not deformed by heat during transfer, glass, metal, ceramics, wood, cloth, or dye acceptance Any medium may be used. Further, at least a part of the medium of the support 101 may be subjected to image, coloring, printing, or other decoration. Although FIG. 2 illustrates an image formed on the image receiving layer 103 by an image formed by a sublimation transfer type thermal transfer method, it is not limited to the presence or absence of the image receiving layer 103.

  (Image) A particularly preferable image 105 is an image having inferior durability, for example, a long thermal transfer film in which a large number of colored thermal transfer layers of yellow, magenta, and cyan (and black if necessary) are repeatedly provided in the surface order. 3 is an image obtained by a thermal transfer method of a melt transfer type or a sublimation transfer type. In the case of creating an ID card such as an ID card, in the case of the melt transfer type, it is easy to form images such as letters and numbers, but these images have durability, particularly friction resistance. There is a disadvantage of being inferior. On the other hand, in the case of the sublimation transfer type, it is possible to form a gradation image such as a facial photograph, but unlike the normal printing ink, the formed image has no vehicle, so light resistance, weather resistance, There is a problem that durability such as friction resistance is inferior. The image is transferred to the surface using the hard coat layer transfer foil 10 of the present invention, so that the hard coat layer 15 is located on the outermost surface, protecting the image and enhancing the durability.

  (Durability) The pencil hardness test of the hard coat layer 15 was measured in accordance with JIS-K5400 and had a hardness of H or higher. Further, the scratch strength of the hard coat layer 15 is 150 g or more, preferably 200 g or more, from the viewpoint of sufficient friction resistance on the surface. The scratch strength was measured using a wear resistance tester (HEIDON-18) on a sample conditioned at 23 ° C. and 55% RH for 24 hours, with a 0.8 mmφ sapphire needle at a right angle. As a result, the load applied to the sapphire needle was gradually increased from 0 g to 200 g, and the load when the surface began to be scratched was measured while sliding and moving the sample surface at 60 cm / min. The larger the load, the better.
