Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in an image-receiving sheet for thermal transfer recording when a thermal sublimation dye is used for transfer recording.

[0002]

2. Description of the Related Art A thermal recording system, which can obtain a recorded image at the same time as an input signal, is relatively simple and inexpensive and has low noise. Therefore, it is widely used in various fields such as facsimiles, computer terminal printers, and measuring instrument printers. It's being used. As a recording medium used in these thermal recording systems, a so-called color-developing type heat-sensitive recording paper, which causes a chemical change by heating to develop a color, is most commonly used. However, color-type thermosensitive recording paper is liable to cause unnecessary color development during the manufacturing process and during storage, and also has poor storage stability of the recorded image, resulting in a decoloring phenomenon due to contact with organic solvents and chemicals. There is a difficulty to cause.

As a recording medium replacing the color-developing type thermosensitive recording paper, there is a recording system using a recording medium using a colored coloring material itself. For example, in JP-A-51-15446, a coloring material that is solid or semi-solid at room temperature is coated on a support such as paper or plastic film, and the coloring material on the support and the recording paper are used. There is a system in which the recording material is brought into contact with the recording material and the coloring material on the support is heated by the thermal recording head and transferred to recording paper to obtain a recorded image. In this recording method, a coloring material on a support is melted, evaporated, or sublimated by heat and transferred to a recording paper to obtain a recorded image by adhesion, adsorption, or dyeing, and plain paper can be used as the recording paper. There are features.

Among the above-mentioned recording methods, the recording method using a sublimation dye as a coloring material has been attempted to be applied to full-color recording applications because an image excellent in gradation can be obtained. However, when plain paper is used as the recording paper in this recording method, the dyeing property is not particularly sufficient, so that not only the color density of the recorded image is low, but also a problem that a remarkable fading phenomenon occurs over time occurs. is there.

Therefore, JP-A-57-107885, JP-A-59-165688 and US Pat.
In Japanese Patent Laid-Open No. 018484, an image receiving sheet having an image receiving layer containing a thermoplastic resin as a main component is proposed in order to improve the above problems. By forming an image-receiving layer containing a thermoplastic resin as a main component, the recording sensitivity and the storability of a recorded image are improved, but the image-receiving layer mainly containing a thermoplastic resin has a high gloss surface. Will be.
Therefore, for the purpose of making the surface of the image receiving layer matte or improving the writability, the image receiving layer is provided with heavy calcium carbonate, light calcium carbonate, talc, clay, natural silicic acid, synthetic silicic acid, titanium oxide. There is also a proposal to add an inorganic or organic pigment such as aluminum hydroxide, zinc oxide or urea formaldehyde resin powder. (JP-A-59-2146
96, JP 61-11293, JP 2
However, when an inorganic or organic pigment is contained in the image receiving layer, there are drawbacks that heat fusion occurs during recording in proportion to the addition amount of these and the image quality is deteriorated, and the amount used is limited. Therefore, the recording surface cannot be sufficiently matted and its improvement has been desired.

DISCLOSURE OF THE INVENTION The present invention is an image-receiving sheet for thermal transfer recording using a heat sublimable dye, and has excellent printability which does not cause heat fusion with the transfer sheet during printing. The present invention provides an image-receiving sheet having a matt recording surface without lowering recording sensitivity and image quality.

[0007]

DISCLOSURE OF THE INVENTION The present invention provides a thermal transfer recording image-receiving sheet comprising a support and an image-receiving layer for receiving a transfer image from a color material transfer sheet, and at least the outermost layer constituting the image-receiving layer. Containing (a) an aqueous dyeing resin, (b) a carboxy-modified silicone compound, (c) vinyl polymer particles, (d) a polyfunctional aziridine derivative compound and / or a polyfunctional oxazoline derivative compound. An image receiving sheet for thermal transfer recording.

[0008]

In the image-receiving sheet for thermal transfer recording of the present invention, the water-based dyeing resin, which is the main constituent of the image-receiving layer, has a function of adsorbing the dye thermally transferred from the transfer sheet and is water-soluble or water-soluble. Intended for dispersible thermoplastics. For example, polyester, polystyrene, polyurethane, vinyl acetate copolymer, acrylic polymer and /
Alternatively, a copolymer, an epoxy resin, an acetate resin, a nylon resin or the like can be used.

Specific examples of the above water-based dyeing resin include:
For example, “Product name: PLUSCOAT Z” manufactured by Kyouso Kagaku Co., Ltd.
Series "," Product Name: Polyester WR Series "manufactured by Nippon Synthetic Chemical Industry Co., Ltd.," Product Name: Toyobo Co., Ltd. "
Byronal series "," Product name: Hydran AP series, Hydran HW series, Finetex ES series "manufactured by Dainippon Ink and Chemicals, Inc.," Product name: PES Resin series "manufactured by Takamatsu Yushi Co., Ltd., Eastman Product name: Eastman WNT-S manufactured by Kodak
And the like.

As the water-based dyeable resin, a resin having a glass transition temperature of 30 to 130 ° C., more preferably 60 to 110 ° C. is preferably used. By the way, the resin below 30 ° C causes thermal bleeding at the time of recording, and the recorded image is easily blurred,
Further, the resin having a temperature higher than 130 ° C. tends to lower the sensitivity.

The carboxy-modified silicone compound is used for the purpose of a releasing agent which prevents the transfer sheet from being heat-sealed to the image-receiving sheet during thermal transfer, and one is provided at the terminal and / or side chain of the silicone compound. Those having the above-mentioned carboxyl groups are used. For example, various types and multi-form types such as oil-like, emulsion-like, etc. have been developed for fiber treatment agents, release agents, surface treatments, lubricants, etc. It is commercially available. Among them, a carboxy-modified silicone compound in the form of microemulsion is particularly preferable because it has remarkable effects.

The vinyl polymer fine particles are used for the purpose of matting the surface of the image receiving layer of the image receiving sheet,
Styrene, α-methylstyrene, 4-methylstyrene,
Polymer fine particles containing vinyl monomers such as 2-methylstyrene, 4-methoxystyrene, vinyl chloride, vinylidene chloride, ethylene, vinylcyclohexane, methyl methacrylate, ethyl methacrylate, methyl acrylate, hexyl acrylate, vinyl acetate, and acrylonitrile as main components. This means that polymer fine particles containing polystyrene as a main component are preferably used.

In order to further improve the water dispersibility of the vinyl polymer fine particles in the preparation of the coating liquid for forming the image receiving layer, a small amount of α, β-ethylenically unsaturated carboxylic acid such as, for example, Acrylic acid, methacrylic acid, maleic acid, itaconic acid, fumaric acid, etc. may be added. In this case, it is desirable that the addition amount of the acid monomer is 5% by weight or less based on the polymer particles.

The vinyl-based polymer fine particles used in the present invention are spherical, polynuclear, or polynuclear by an emulsion polymerization method, a suspension polymerization method or the like by selecting an appropriate monomer or monomer mixture.
It can be obtained in any form such as a multi-layered form or a hollow form, but it can also be obtained by mechanically pulverizing a lump of polymer.
In the present invention, it is particularly important to control the particle size of the vinyl polymer fine particles to be contained in the image receiving layer, and in order to obtain a sufficient matte image receiving sheet, the particles are in an independent dispersed particle state and have an average particle size of , 0.2 to 5 μm, more preferably 0.3 to 0.8 μm. By the way,
If it is 0.2 μm or less, the matting effect is small, and
When it is 5 μm or more, not only the matting effect is small but also the image quality is significantly deteriorated. The amount of the vinyl-based polymer fine particles used is appropriately determined according to the intended quality setting of the image-receiving sheet, but in order to obtain the effect of matting, 100 parts by weight of the water-dyeable resin is used. On the other hand, it is necessary to add at least 5% by weight or more.

In the present invention, the matting of the image-receiving layer does not necessarily mean a completely matted state. A high gloss image-receiving layer surface can be obtained by using an aqueous dyeing resin when the vinyl polymer fine particles are contained together with a carboxy-modified silicone compound, a polyfunctional azirine derivative compound and / or a polyfunctional oxazillin derivative compound during printing. This means that heat fusion with the transfer sheet does not occur, the recording sensitivity and the image quality are not deteriorated, and the desired matting direction is improved. Therefore, it goes without saying that the amount of the vinyl polymer fine particles to be used is also determined according to the desired degree of matting.

In order to obtain the above-mentioned effects in the image-receiving layer by containing the vinyl polymer particles, the polymer particles are not melted into a film during coating and drying, and coating and drying are performed so as to maintain a fine particle state. There is a need to. Therefore, T at room temperature or higher, more preferably 50 ° C. or higher
The selective use of polymer particles having a g-point is desirable.

The polyfunctional aziridine derivative compound and the polyfunctional oxazoline derivative compound are used for the purpose of a cross-linking agent, and have the functions of improving the storage stability of the print and improving the moisture resistance of the recording material.

As the polyfunctional aziridine derivative compound, for example, 1- (2-methyl) aziridinepropionic acid, 2-ethyl-2 [3- (2-methyl) aziridinyl-1-oxopropoxy] -1-3- Propanediyl ester, tris-2,4,6- (1-aziridinyl)
-1,3,5-triazine, tris [1- (2-methyl) aziridinyl] phosphine oxide, hexa [1
-(2-Methyl) aziridinyl] triphosphatriazine, tri-1-aziridinylphosphine oxide, N,
N-hexamethylene-1,6-bis (1-aziridinecarboxamide), N, N-diphenylmethane-4,4
-Bis (1-aziridinecarboxamide), trimethylolpropane-tri-beta-aziridinylpropionate, tetromethylolmethane-tri-beta-aziridinylpropionate, N, N-toluene-2,4-
Bis (1-aziridinecarboxamide), triethylenemelamine, bisisophthaloyl-1- (2-methylaziridine), tris-1- (2-methylaziridine) phosphine and trimethylolpropane-tri-beta (2-methyl Examples thereof include aziridine) propionate and the like, and aziridine polymers obtained by polymerizing these compounds, but the invention is not limited thereto.

As the polyfunctional oxazoline derivative compound, compounds having two or more oxazoline rings in the molecule are selectively used. Among them, oxazoline is present on the surface of an acrylic, styrene, acrylic / styrene microemulsion or the like. A polyfunctional oxazoline derivative microemulsion represented by a polymer emulsion containing a ring or a monomer having an oxazoli ring as a copolymerization component is easy to handle and excellent in action and effect. , Preferably used. In addition,
In order to obtain the desired effects of the present invention, such microemulsions are used with an average particle size of at least 0.2 μm or less, more preferably 0.1 μm or less.

The present invention provides an aqueous dye-forming resin as described above,
The carboxy-modified silicone compound, the polyfunctional aziridine derivative compound and / or the polyfunctional oxazoline derivative compound, and the vinyl-based polymer fine particles have a significant feature in being used in combination, and the reason is not always clear. By selecting the combination of the present invention, an image receiving layer surface having excellent homogeneity is obtained, heat fusion with the transfer sheet does not occur during printing, and recording sensitivity and image quality are not deteriorated, and still desired. It is possible to improve the matting of the above. Further, the obtained image-receiving sheet is excellent not only in recording sensitivity and image quality but also in storage stability of printing and moisture resistance of the image-receiving sheet, so that it can exhibit advantages in developing applications of the image-receiving sheet.

Since the image-receiving sheet for thermal transfer recording of the present invention can be formed by a coating liquid containing water as a medium, it has advantages in process easiness, safety and workability. Coexistence of volatile amines such as ammonia and triethanolamine not only greatly improves the coating suitability but also maximizes the action and effect, which is the most preferable embodiment.

The image-receiving layer forming the image-receiving sheet for thermal transfer recording according to the present invention has, as described above, (a) at least one water-based dyeing resin, (b) at least one carboxy-modified silicone compound, and (c) vinyl. At least one of the polymer fine particles
And at least one of (d) a polyfunctional aziridine derivative compound and / or a polyfunctional oxazoline derivative compound. The composition ratio is appropriately selected and is not particularly limited, but in general, (b) the carboxy-modified silicone compound is 0.5 to 200 parts by weight with respect to 100 parts by weight of the solid content of the aqueous dyeable resin. , (C) 5 to 500 parts by weight of vinyl polymer fine particles, and (d) 0.5 to 300 parts by weight of polyfunctional aziridine derivative compound and / or polyfunctional oxazoline derivative compound are used. If the amount of (b) added to the (a) water-based dyeable resin is small, heat fusion occurs with the color material transfer layer, while if it is too large, slippage occurs on the sheet. When the amount of (c) added is small, the matting effect is small, while when it is too large, the image density is reduced. When the addition amount of (b) is small, or when it is too large, the desired crosslinking effect cannot be obtained, causing heat fusion,
In addition, the storage stability of printing will be reduced. From this, the more preferable range of addition amount is (a) 100
(B) 5 to 50% by weight, (c) 10 to 100% by weight, and (d) 5 to 100% by weight with respect to parts by weight.

In the present invention, the aqueous coating liquid for forming the image receiving layer is composed of the above-mentioned four components as essential components, but for the purpose of modifying the image receiving layer and imparting other functions, for example, the color tone and the Dye for whiteness control,
Addition of pigments and / or fluorescent dyes, addition of UV absorbers and antioxidants for improving storage stability, addition of antistatic agents for imparting printer suitability, lubricants, addition of fillers for imparting writability, smearing Various auxiliaries such as addition of dispersant, wetting agent, defoaming agent, and binders for imparting suitability may be added.

The coating amount of the image-receiving layer-forming coating liquid on the support is appropriately adjusted depending on the intended use of the image-receiving sheet, but it is generally applied in the range of about 1 to 15 g / m ² .

In the present invention, at least the outermost layer constituting the image receiving layer is formed by the coating liquid for forming an image receiving layer of the present invention, which has four essential components as described above. In the case of forming by (1), the layers other than the outermost layer are not limited to the coating liquid for forming an image receiving layer of the present invention, and various dyeing resins known in the art can be used. Examples of the dyeable resin include styrene, vinyltoluene,
Polymers and copolymers of vinyl monomers such as acrylic acid ester, methacrylic acid ester, acrylonitrile, vinyl chloride, vinyl acetate; polyester resin, polyamide resin, polycarbonate resin, polysulfone resin,
Examples thereof include condensation polymers such as epoxy resins and polyurethane resins; and thermoplastic resins such as natural semi-synthetic resins represented by cellulose esters. One or more kinds of these thermoplastic resins are appropriately selected, and an arbitrary coating liquid such as an aqueous solution, an aqueous dispersion liquid, an organic solvent solution, etc. is formed, and the coating liquid is dried on the support.

As the support, for example, (1) synthetic paper, (2)
Fine paper, art paper, coated paper, cast coated paper,
Plain paper such as poly-laminated paper, synthetic resin-impregnated paper, emulsion-impregnated paper, and (3) various plastic films or sheets such as polyolefin, polyvinyl chloride, polyester, polycarbonate, etc. can be used. this house
The synthetic paper of (1) has high thermal efficiency and is therefore particularly excellent in recording sensitivity, but it is generally synthetic paper / plain paper / synthetic paper, synthetic paper / plain paper due to problems such as thermal deformation during recording. / Plastic film, synthetic paper / plastic sheet / synthetic paper, etc. The plain paper of (2) is preferably used because it has little thermal deformation and is excellent in economical efficiency, but in order to further improve the adhesiveness and the thermal transfer efficiency, a rubber elastic layer generally formed of synthetic rubber latex, Foaming agent,
It is used in a mold provided with a so-called hollow layer represented by a microporous layer formed of a hollow capsule or the like. A support having poor surface wettability, such as the plastic film or poly-laminated paper of (3), is generally subjected to anchor coating to improve the smearing suitability of the image-receiving layer forming coating solution.

The image-receiving sheet for thermal transfer recording of the present invention thus obtained exhibits extremely excellent performance particularly as an image-receiving sheet when a sheet containing a heat sublimable dye is used as a color material transfer sheet. Not only does it provide a matte tone with excellent recording sensitivity and an extremely clear recorded image with high color density, it also does not cause thermal fusion between the image receiving sheet and the color material transfer layer, and also has excellent storage properties after recording. We have completed an image-receiving sheet that will exhibit.

The heat sublimable dye referred to in the present invention does not cause the color material to transfer even when it comes into contact with the image receiving sheet under normal handling conditions. However, for example, it is melted, evaporated, or heated only at 60 ° C. or higher. It means a dye that causes a transition of a coloring material due to sublimation, for example, disperse dyes represented by azo, nitro, anthraquinone, quinoline, etc., and basic dyes represented by triphenylmethane, fluorane. , An oil-soluble dye, and the like, and appropriately selected from various dyes to be used.

Further, the image-receiving sheet for thermal transfer recording of the present invention is not limited to the thermal recording system of contact heating with a thermal plate of a thermal printing unit, a thermal head, etc., but also a heat ray of infrared lamp, YAG laser, carbon dioxide gas laser, etc. It is also useful for thermal recording by a non-contact heating method using radiation.
