Description

The present invention relates to a recording medium in a sublimation type thermal transfer recording system.

[Conventional technology]

With the recent rapid spread of office automation, the number of color displays in personal computers, word processors, office computers, etc., which are the core of the office automation, has increased rapidly, and the demand for the practical use of a recording method from color signals has been rapidly increasing. In the field of dry copiers, there are strong demands for colorization.

Conventional color recording methods include a light pen method, a wire dot method, and an inkjet method, but each has drawbacks such as a low recording speed, noise, and clogging of minute nozzles through which ink is ejected. On the other hand, the sublimation type thermal transfer recording method does not generate any noise and the handling, maintenance,
It has features such as easy management. In addition, this method is a method of heating a transfer sheet coated with a sublimable dye with a thermal recording head to sublimate and transfer the dye to a recording medium to obtain color recording, so that the energy applied to the thermal head should be adjusted. Since the sublimation amount of the dye can be controlled by this, gradation expression is easy, and it is particularly advantageous in obtaining a full-color hard copy as compared with other recording methods. However, regarding this method, even if the recording principle and characteristics were announced as described above,
Under the present circumstances, a recording material excellent in color developability and color tone clarity by a sublimable disperse dye has not yet been developed, and there has been no case on the market, and its development has been strongly demanded.

[Problems to be solved by the invention]

An object of the present invention is to provide a disperse dye dry transfer recording medium which is easily dyed with a disperse dye in a sublimation type thermal transfer recording system and which is excellent in color developability and sharpness.

[Means for solving problems]

According to the present invention, 10 to 70 parts by weight of a crosslinker curable with active energy rays and at least one (meth) acrylic acid alkyl ester polymer on the surface of a substrate, the (meth) acrylic acid alkyl ester component Polymer containing 50% by weight or more and having a Tg of 40 ° C. or more
0 to 30 parts by weight (chosen so that the sum of both is 100 parts by weight) and 0.1 based on 100 parts by weight of the total amount of both.
To 30 parts by weight of a coating composition comprising a mixture of a phosphoric acid ester compound and an amine compound, the film having a thickness of 0.5 to 1 cured by irradiation with active energy rays.
Provided is a sublimation-type disperse dye thermal transfer recording type recording medium having a cured film of 00 μm.

Further, according to the present invention, 10 to 70 parts by weight of a cross-linking agent curable by active energy rays, and at least one kind of (meth) acrylic acid alkyl ester polymer, wherein (meth) acrylic acid alkyl ester component is 50 parts by weight. % Or more and its Tg is 40 ° C. or higher 90 to 30
Parts by weight (chosen so that the sum of the two is 100 parts by weight),
A coating composition comprising 0.1 to 30 parts by weight of a mixture of a phosphoric acid ester compound and an amine compound and a photopolymerization initiator is coated on one side of a substrate based on 100 parts by weight of the total amount of both. Then, a method for producing a recording medium of a sublimation type disperse dye thermal transfer recording system is provided, which comprises forming a cured film having a film thickness of 0.5 to 100 μm by irradiating and curing with an active energy ray. .

According to the present invention, the above-mentioned specific (meth) acrylic acid alkyl ester polymer, a cross-linking agent, a phosphoric acid ester compound, and an amine compound are main components on the surface of a substrate (for example, a film or paper). The recording medium obtained by applying the coating composition (for example, to a thickness of 0.5 to 100 μm) and curing with active energy rays is easily dyed with a sublimable disperse dye, and its coloring property and vividness are excellent. It has been found to be good as well as having improved blocking properties with transfer sheets coated with disperse dyes.

The (meth) acrylic acid alkyl ester polymer used in the present invention is a polymer of (meth) acrylic acid alkyl ester having a substituted or unsubstituted alkyl group or a copolymer thereof. Examples of the copolymerizable monomer include styrene and (meth) acrylic acid. Examples of the substituent of the alkyl group include a hydroxyl group, an amino group and a carboxyl group. The (meth) acrylic acid alkyl ester polymer essential to the present invention is a polymer containing 50% by weight or more of a (meth) acrylic acid alkyl ester component, and its Tg is 40 ° C. or higher.

When the Tg of the polymer is less than 40 ° C., the transfer sheet coated with the sublimable disperse dye and the recording medium adhere to each other when heated by the thermal recording head, that is, the phenomenon of blocking easily occurs. On the other hand, when the content of the (meth) acrylic acid alkyl ester component in the polymer is less than 50% by weight, the color developability of the sublimable disperse dye is lowered.

The compounding amount of the (meth) acrylic acid alkyl ester polymer is 30 with respect to 100 parts by weight of the mixture of the crosslinking agent and the polymer.
To 90 parts by weight, preferably 40 to 85 parts by weight.
The amount of the (meth) acrylic acid alkyl ester polymer is 30.
If it is less than 100 parts by weight, the color developability of the sublimable disperse dye will be deteriorated. On the contrary, if it exceeds 90 parts by weight, blocking tends to occur at the time of heating by the thermal recording head and curing property by active energy rays may be deteriorated. It becomes inferior or the adhesiveness to the base material deteriorates.

90/10, methyl methacrylate / methyl acrylate / 2-hydroxyethyl methacrylate = 80/15
/ 5, methyl methacrylate / iso-butyl methacrylate / dimethylaminoethyl methacrylate = 80/1
Examples thereof include copolymers such as 5/5. These polymers may be used alone or in a mixture of two or more.

The polyfunctional monomer is indispensable in order to cure the coating composition with active energy rays,
Monofunctional monomers are not essential.

However, when the coating composition is applied without using a solvent, it is better to use a monofunctional monomer in order to reduce the viscosity of the coating composition.

However, when a monomer or oligomer having poor curability due to ultraviolet irradiation in air is used, the surface of the coating film becomes sticky or blocking occurs. Specific examples of the compound represented by the above general formula include dipentaerythritol tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol hexaacrylate, tripentaerythritol pentaacrylate, tripentaerythritol hexaacrylate, tripentaerythritol heptaacrylate and the like. Can be mentioned.

The compounding amount of the above-exemplified crosslinking agent is 10 to 70 parts by weight, preferably 15 to 60 parts by weight, based on 100 parts by weight of the total amount of the crosslinking agent and the (meth) acrylic acid alkyl ester polymer. When the amount of the cross-linking agent exceeds 70 parts by weight, the blocking resistance is improved but the dyeability is deteriorated.
On the contrary, if it is less than 10% by weight, blocking will come out.

Such blocking becomes more remarkable as the amount of energy applied to the thermal head (thermosensitive recording head) increases and the temperature rise of the thermal head increases, but a mixture of a phosphate ester monomer and an amine compound is crosslinked. It was found that when it was added in an amount of 0.1 to 30 parts by weight based on 100 parts by weight of the mixture of the agent and the (meth) acrylic acid alkyl ester polymer, blocking property was significantly improved and dyeing density was also improved.

It is a monomer selected from the group consisting of methacryloxyethyl phosphate. Other examples of the phosphorus-containing monomer include halogenated vinyl phosphate and alkyl-substituted vinyl phosphate, but they are not preferable because they have insufficient curing characteristics with active energy rays.

As the amine compound, the general formula (II), [In the formula, at least one Y is a general formula; (In the formula, R ₃ represents an alkylene group having 1 to 10 carbon atoms, and m is an integer of 1 to 10) and the rest is a hydrogen atom or an alkyl group having 1 to 20 carbon atoms.

May be incorporated into the coating composition. It should be noted that, as in Comparative Examples described later, the blocking property cannot be improved and the dyeing density of the sublimable disperse dye cannot be improved with only one of the phosphate ester monomer and the amine compound. The mixing ratio of the phosphate ester-based monomer and the amine-based compound is preferably in the range of 1/4 to 4/1 in terms of molar ratio.

By the way, when an electron beam is used as an active energy ray when curing a coating composition composed of the above crosslinking agent, (meth) acrylic acid alkyl ester polymer, phosphoric acid ester monomer and amine compound, It is not necessary to add a photopolymerization initiator, but a wavelength of 10
When using UV light of 0 to 800 nm, a photopolymerization initiator or a photosensitizer is used in an amount of 0.1 to 1 with respect to 100 parts by weight of the crosslinking agent and the (meth) acrylic acid alkyl ester polymer mixture.
It is preferable to add 0.0 parts by weight. Specific examples of the photopolymerization initiator include benzoin, benzoin isobutyl ether, benzyl dimethyl ketal, ethylphenyl glyoxylate, diethoxyacetophenone, 1,1-dichloroacetophenone, 4'-isopropyl-2-hydroxy-2-methylpropio. Carbonyl compounds such as phenone, 1-hydroxycyclohexyl phenyl ketone, benzophenone, benzophenone / diethanolamine, 4,4'-bisdimethylaminobenzophenone, 2-methylthioxanthone, tert-butylanthraquinone, benzyl; tetramethylthiuram monosulfide, tetramethylthiuram.

The roll coating method, the bar coating method, the spray coating method, the gravure coating method, the curtain coating method, the bead coating method, the flow coating method, the dip coating method and the like can be used for coating, but in order to improve workability. It is advisable to add a solvent (for example, ethyl alcohol, isopropyl alcohol, acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, dimethylformamide, etc.) to these compositions to adjust the coating viscosity to an appropriate level.

The thickness of the coating composition layer formed on the substrate surface is 0.
It is necessary to set it to 5 to 100 μm. For even better results, the film thickness should be 1 to 50 μm. When the film thickness becomes thinner than 0.5 μm, the diffusion of the dye reaches saturation on the way, and the dye cannot be dyed in a dark color. On the other hand, if the film thickness exceeds 100 μm, blocking tends to occur during heating.

In order to prevent disperse dye transfer when the dyed films or papers are stacked, it is better to apply the composition forming the dye layer on only one side of the substrate, but this dye transfer should be positive. In order to prevent dyeing, it is more preferable to provide a non-migration layer on the surface opposite to the dyeing layer.

As the composition for forming the non-migration layer, 100 parts by weight of a mixture of the above-mentioned polyfunctional monomer or the above-mentioned polyfunctional monomer and a monofunctional monomer and an oligomer, and, if necessary, the above-mentioned photopolymerization initiator A coating agent consisting of 0.1 to 10.0 parts by weight can be used, but in order to sufficiently prevent migration with a disperse dye, a monomer,
It is necessary that the oligomer mixture has an average of 1.5 or more polymerizable groups per molecule. Similar to the coating composition for forming a dyed layer, these coating agents can also be used for adjusting viscosity with a solvent, coating and curing.

The film-like or paper-like substrate used for the recording medium of the present invention may be any one as long as it is generally used as a substrate for dry transfer. Specific examples of the film / paper include polyester films, propylene films, nylon films, vinyl chloride films, and other film-like materials; wood-based art paper, acrylic fiber-based acrylic paper, polyester paper, etc. Paper-like materials are mentioned, and polyester film or acrylic paper or art paper is particularly preferable in consideration of heat resistance, and polyester film is most preferable in consideration of transparency of the article.

These papers or films may be used as they are, or if necessary, those that have been subjected to pretreatments such as washing, etching, corona discharge, active energy ray irradiation, dyeing and printing. Good.

In order to prepare the recording medium of the present invention, first, the above-mentioned coating composition is usually uniformly mixed in advance and applied to the surface of paper or film.

Next, the coating film on the paper or film is cured by active energy rays.

As the active energy rays, ultraviolet rays emitted from a radiation source such as a xenon lamp, a low-pressure mercury lamp, a high-pressure mercury lamp or an ultra-high-pressure mercury lamp, an electron beam normally extracted from an electron beam accelerator of 20 to 2000 kV, an α ray, a β ray, a γ ray, etc. And the like. Considering handling and workability, ultraviolet rays having a wavelength of 100 to 800 nm are preferable.
