Description

  The present invention relates to a thermal transfer image receiving sheet, and more particularly to a novel thermal transfer image receiving sheet made of a specific material and having excellent antistatic properties.

  Conventionally, various thermal transfer methods are known. Among them, a sublimation dye is used as a recording agent, and this is supported on a substrate sheet such as paper or a plastic sheet to form a thermal transfer sheet, and dyed with a sublimation dye. Various methods have been proposed for forming various full-color images on a heat transfer image-receiving sheet that can be applied, for example, a thermal transfer image-receiving sheet provided with a dye-receiving layer on the surface of paper or plastic film.

  In this case, a thermal head of the printer is used as a heating means, and a large number of three or four color dots are transferred to the thermal transfer image receiving sheet by heating for a very short time, and the full color image of the original is printed by the multicolored color dots. Is reproduced. The image formed in this way is very clear because the color material used is a dye, and is excellent in transparency. Therefore, the obtained image is excellent in reproducibility and gradation of intermediate colors. High-quality images comparable to full-color photographic images can be formed.

  Plastic sheets, laminated sheets of plastic sheets and paper, synthetic paper, etc. are used as thermal transfer image receiving sheets used in the sublimation type thermal transfer system, but the use of the sublimation type thermal transfer system will be expanded to general offices. Therefore, it is required to use plain paper such as coated paper (art paper), cast coated paper, and PPC paper as a base sheet of the thermal transfer image receiving sheet. Further, the sublimation thermal transfer system is useful for the formation of an OHP image, and an OHP thermal transfer image receiving sheet capable of forming a high-quality image excellent in transparency and the like is also required.

  The thermal transfer image-receiving sheet has a high surface specific resistance value of various materials constituting the thermal transfer image-receiving sheet, particularly the above-mentioned various materials constituting the base sheet. When the back layer (slip layer) or the like is formed, the thermal transfer image receiving sheet is wound or cut, stored in a cassette, packed in a box or the like, it is easily charged by mutual friction. Further, in use, there is a problem that charging tends to occur at the time of contact with a paper feed roll or a thermal transfer sheet or at the time of peeling from the thermal transfer sheet after printing.

  When the thermal transfer image receiving sheet is charged, dust or the like is likely to adhere to the surface thereof, and as a result, the thermal transfer sheet that comes into contact with the thermal transfer image receiving sheet is creased and the resolution of the formed image is deteriorated. is there. Similarly, the thermal transfer sheet is also charged, and the thermal transfer sheet and the thermal transfer image receiving sheet are adhered to each other, which causes a problem in the transportability of the thermal transfer sheet and the thermal transfer image receiving sheet. In a more severe case, there may be a case where a spark is caused when the thermal transfer sheet or the thermal transfer image receiving sheet is replaced or inserted, or an impact is given to the human body. Such a problem occurs not only in an opaque thermal transfer image receiving sheet mainly composed of a paper core material but also in a transparent thermal transfer image receiving sheet used for OHP or the like.

  In order to prevent charging, it is known to form an antistatic layer on the surface of the thermal transfer image-receiving sheet with a surfactant or the like. In this case, the thermal transfer image-receiving sheet may become sticky or an antistatic agent may be used. There is a problem of shifting to the back layer. Further, these problems are accompanied by a problem that the antistatic effect decreases with time.

  As another antistatic method, there is a method of forming a conductive layer using a conductive material of a metal oxide such as conductive carbon black or tin oxide and a binder, but these conductive agents are of a color such as black. In many cases, the appearance of the resulting thermal transfer image-receiving sheet is inferior.

As a method for solving the above problems, a method of forming an antistatic layer with an acrylic resin having a quaternary ammonium base has also been proposed (for example, Patent Document 1). Adhesiveness with other resins is poor, and materials are considerably limited. Moreover, although it is slightly, there exists a problem that antistatic performance changes with environments.
JP-A-2-182491

  The present invention has been made in view of the above circumstances, and an object thereof is to provide a thermal transfer image receiving sheet that stably has excellent antistatic performance.

  That is, the present invention is a thermal transfer image-receiving sheet in which at least a dye-receiving layer is provided on at least one surface of a base sheet, and the lithium ion conductive resin is at least on the outermost surface layer or below the outermost surface layer (base material sheet side). It is related with the thermal transfer image receiving sheet characterized by including in the layer.

  The thermal transfer image-receiving sheet of the present invention basically comprises at least a dye-receiving layer 2 provided on at least one surface of a base sheet 1 as shown in FIG. In this configuration, the lithium ion conductive resin is contained in the outermost dye receiving layer.

  As the base sheet, various transparent to opaque plastic films and sheets, various papers such as synthetic paper, fine paper, art paper, coated paper, cast coated paper, wallpaper, backing paper, synthetic resin or emulsion-impregnated paper, Paper such as synthetic plastic impregnated paper, synthetic resin internal paper, and paperboard is preferred. Although the thickness of these base material sheets is arbitrary, generally it is the thickness of about 30-200 micrometers.

  A laminate in which a foamed resin sheet, for example, a synthetic paper made of foamed polypropylene, foamed polyethylene, foamed polystyrene, or foamed resin sheet, is laminated as a cushion layer on both surfaces of the base sheet can also be used as the base sheet. In view of various strengths, cushioning properties, etc., foamed polypropylene is preferred. A suitable thickness of these cushion layers is 30 μm to 80 μm.

  In addition, when the adhesive force with the dye receiving layer formed on the surface of the base sheet is poor, the surface may be subjected to primer treatment or corona discharge treatment.

  The dye receiving layer is for receiving the sublimable dye transferred from the thermal transfer sheet and maintaining the formed image. Examples of the binder resin for forming the dye receiving layer include polyolefin resins such as polypropylene, vinyl halide resins such as polyvinyl chloride and polyvinylidene chloride, vinyl resins such as polyvinyl acetate and polyacrylic ester, Copolymers of vinyl halide monomers and vinyl monomers, polyester resins such as polyethylene terephthalate and polybutylene terephthalate, polystyrene resins, polyamide resins, and copolymers of olefins such as ethylene and propylene with other vinyl monomers Examples thereof include system resins, ionomers, cellulose resins such as cellulose diacetate, and polycarbonates. Preferred are vinyl resins (including copolymer resins) and polyester resins. In the present invention, it is possible to provide a thermal transfer image-receiving sheet for OHP that can form a high-quality image excellent in anti-static property, transparency, adhesiveness, etc., using a transparent polyester base sheet used for OHP, etc. is there.

  The dye-receiving layer may contain a release agent in order to impart good release properties to the thermal transfer sheet. Examples of the mold release agent include silicone oil, phosphate ester-based surfactant, fluorine-based surfactant, and the like, but silicone oil is preferable. As the silicone oil, modified silicone oils such as epoxy modification, alkyl modification, amino modification, carboxyl modification, alcohol modification, fluorine modification, alkylaralkyl polyether modification, epoxy / polyether modification, and polyether modification are desirable. One or more mold release agents are used.

  The addition amount of the release agent is about 1 to 20 parts by weight with respect to 100 parts by weight of the binder resin. When the range of the addition amount is not satisfied, problems such as fusion of the thermal transfer sheet and the dye receiving layer or a decrease in printing sensitivity may occur.

  The dye receiving layer may be of any thickness, but is generally 1 to 50 μm thick. The dye-receiving layer is preferably a continuous coating, but may be formed as a discontinuous coating using a resin emulsion or resin dispersion.

  The dye-receiving layer is prepared by adding a necessary additive such as an antioxidant or an ultraviolet absorber to a binder resin as described above on an appropriate organic solvent on at least one surface of the base sheet. A dispersion which is dissolved or dispersed in an organic solvent or water is formed by applying and drying by a forming means such as a gravure printing method, a screen printing method, or a reverse roll coating method using a gravure plate.

The lithium ion conductive resin is a conductive resin containing lithium in an ionic state. The lithium ion conductive resin is an organic or inorganic electrolyte lithium salt, such as LiClO ₄ , LiBF ₄ , LiCF ₃ SO ₃ , LiC ₄ F ₉ SO _3, or the like, which is ionized and contained in a polyol or polyester resin. It is an organic conductive resin and has a conductivity of about 10 ⁸ Ω · cm. As such resin, for example, PEO-20R (manufactured by Sanko Chemical Industry Co., Ltd.) and VC-2220R (manufactured by Sanko Chemical Industry Co., Ltd.) are available.

In the thermal transfer image receiving sheet having the structure shown in FIG. 1, the conductive resin is contained in the dye receiving layer. When a lithium ion conductive resin is contained in the dye-receiving layer, antistatic properties can be imparted to the thermal transfer image-receiving sheet. In addition, the adhesion between the dye-receiving layer and the substrate sheet is improved, and the transparency is also excellent. The amount of the conductive resin added is about 0.1 to 30 parts by weight per 100 parts by weight of the binder resin. The surface resistance of the thermal transfer image-receiving sheet finally obtained 3.0 × ^{10 13} Ω / cm ² or less, may be used in an amount such preferably becomes 4.0 × ^{10 12} Ω / cm ² or less). As a method of inclusion, an appropriate amount of conductive resin may be added to the dye-receiving layer coating solution. If the amount added is too small, the desired antistatic effect cannot be obtained. On the other hand, if the amount added is too large, the cost increases.

  FIG. 2 shows another embodiment of the thermal transfer sheet. An antistatic layer 3 is provided between the base sheet 1 and the dye receiving layer 2. The outermost surface layer is a dye receiving layer, and the layer below the outermost surface layer is an antistatic agent layer.

The base sheet 1 and the dye receiving layer 2 can be applied in the same configuration as that described in FIG. However, the lithium ion conductive resin is contained in the antistatic layer 3. The antistatic layer 3 contains a lithium ion conductive resin and a binder resin as main components. At the same time, the dye-receiving layer 2 may contain a lithium ion conductive resin, but on either side of the base sheet, the lithium ion conductive resin may be contained in one of the layers.
Examples of the binder resin include polyester resins, polyurethane resins, polyacrylic resins, polyvinyl formal resins, epoxy resins, polyvinyl butyral resins, polyamide resins, polyether resins, polystyrene resins, and styrene-acrylic resins. Examples thereof include copolymer resins. A binder resin preferable from the adhesiveness with a base material sheet is a polyester resin.

  The antistatic layer 3 is a coating solution obtained by dissolving or dispersing a binder and a lithium ion conductive resin in a suitable solvent such as acetone, methyl ethyl ketone, toluene, xylene, ethyl acetate, or a solvent containing water, for example, water. And a coating solution dissolved or dispersed in a mixture of a water-soluble organic solvent such as methanol, ethanol, isopropyl alcohol, and normal propyl alcohol on one surface of the base sheet, for example, a gravure coater, a roll coater, a wire bar, etc. It is formed by coating and drying by a conventional coating method. The composition of the coating liquid is about 2 to 50% by weight, preferably 3 to 20% by weight of binder resin, about 0.002 to 15% by weight of lithium ion conductive resin, preferably 0.05 to 10% by weight and the balance. A composition consisting of an amount of solvent is preferred. Arbitrary additives such as a surfactant and an antifoaming agent for suppressing air bubbles may be added to the coating liquid in order to improve the wettability of the base sheet during coating.

The coating amount is about 0.02~10.0g / ^{m 2} as solid content of the coating solution, preferably in the range of about 0.07~5.0g / ^{m 2.} It is difficult to impart performance as an antistatic layer. On the other hand, even if the coating amount exceeds the above range, the antistatic performance does not improve in proportion to the thickness, which is economically disadvantageous. However, the antistatic layer 3 takes into account the relationship with the receiving layer so that the surface resistance (receiving layer side) of the finally obtained thermal transfer image receiving sheet is 3.0 × 10 ¹³ Ω / cm ² or less. Need to form.

  The antistatic layer of the present invention is excellent in adhesion, excellent in adhesion between the dye-receiving layer and the antistatic layer and between the substrate and the antistatic layer, and also excellent in transparency.

FIG. 3 shows another embodiment of the thermal transfer sheet. In the thermal transfer sheet of FIG. 3, a back surface layer 4 is formed on the surface of the base material sheet 1 opposite to the dye receiving layer 2. The outermost surface layer is a dye demand layer or / and a back surface layer. The base sheet 1 and the dye receiving layer 2 can be applied in the same configuration as that described in FIG. For the purpose of improving the transportability of the thermal transfer image-receiving sheet in the printer, the back layer is, for example, by adding a resin having excellent lubricity such as an acrylic resin or an acrylic silicone resin or appropriate lubricous particles thereto, for example, It is formed as a layer of 1 to 5 g / ^{m 2} a thickness of about.

  The lithium ion conductive resin may be contained in the back layer, but may also be contained in the dye receiving layer at the same time. When it is not contained in the back surface layer, it may be contained in the receiving layer 2, or when an antistatic layer is provided as in the configuration of FIG. 2, it may be contained in the antistatic layer.

  When the lithium ion conductive resin is contained in the back layer, the same method and amount as in the case where the lithium ion conductive resin is contained in the dye-receiving layer in FIG. 1 can be applied.

  When lithium ion conductive resin is contained in the back layer, the antistatic property is imparted to the thermal transfer image-receiving sheet, the adhesion between the back layer and the base sheet is improved, and the transparency is also excellent.

  FIG. 4 shows another embodiment of the thermal transfer sheet. An antistatic layer 5 is provided between the base sheet 1 and the back surface layer 4. The lithium ion conductive resin is contained in the antistatic layer or / and the dye receiving layer. The outermost surface layer is the dye receiving layer and / or the back surface layer, and the layer below the outermost surface layer is the antistatic agent layer 5. The base sheet 1 and the dye-receiving layer 2 can be applied with the same configuration and formation method as described in FIG. The antistatic layer 5 can be applied with the same configuration and formation method as described in FIG.

  In the thermal transfer receiving sheet of the present invention, an intermediate layer may be further formed between the receiving layer and the antistatic layer, between the base material and the antistatic layer, and between the back layer and the antistatic layer, if necessary. As the intermediate layer, a layer that has been conventionally formed by using polyester resin or the like and containing ultrafine silica or the like may be formed. However, the surface resistance described above is the final heat transfer image-receiving sheet. It is necessary to form it in consideration of having such a value.

  The lithium ion conductive resin used in the present invention can be used in the same manner for a pressure-sensitive adhesive layer of a peelable substrate such as a seal type, and can impart antistatic properties.

The thermal transfer sheet used when performing thermal transfer using the thermal transfer image-receiving sheet of the present invention is one in which a dye layer containing a sublimation dye is provided on paper or a polyester film, and any conventionally known thermal transfer sheet is used as it is. Can be used. Further, the means for applying thermal energy at the time of thermal transfer is not particularly limited, and any conventionally known means for applying can be used. For example, by controlling the recording time with a recording device such as a thermal printer (for example, a video printer VY-100 manufactured by Hitachi, Ltd.), thermal transfer is performed by applying thermal energy of about 5 to 100 mJ / mm ^2. Just do it.
