Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] 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, color displays are rapidly increasing in the core computers, word processors, office computers, etc., and the demand for practical use of recording methods from color signals is rapidly increasing. There is also a strong demand for color in the field of dry copying machines.

Conventional color recording methods include a light pen method, a wire dot method, and an inkjet method, but each method has drawbacks such as slow recording speed, noise, and clogging of the tiny nozzles that eject ink. On the other hand, the dye-sublimation heat-sensitive transfer recording method does not generate any sound and is easy to operate, maintain, and operate the copying machine.
It has characteristics such as easy management. In addition, in this method, a transfer sheet coated with a sublimable dye is transferred to a thermal recording medium, and the dye is sublimated and transferred to the recording medium by heating with a dome to obtain color recording, so the energy applied to the thermal head is adjusted. By doing so, the amount of sublimation of the dye can be controlled, making it easy to express gradation, and compared to other recording methods, it is particularly advantageous in obtaining full-color hard copies. However, even though the recording principles and characteristics of this method have been announced as above,
The current situation is that a recording material with excellent color development and color clarity using sublimable disperse dyes has not yet been developed, and there has been no example of such a material being coated, and there has been a strong demand for its development.

[Problem that the invention seeks to solve]

An object of the present invention is to provide a recording medium for disperse dye dry transfer that can be easily dyed with a disperse dye in a sublimation type thermal transfer recording system and has excellent color development and clarity.

[Means for solving problems]

According to the present invention, a 100:1 mixture consisting of 10 to 70 parts by weight of a crosslinking agent curable by active energy radiation and 30 to 90 parts by weight of a (meth)acrylic acid alkyl ester polymer of at least 1 s is added to the substrate surface according to the present invention. A sublimation product obtained by applying a coating composition consisting of o, oi to 10 parts by weight of at least one silicone surfactant and/or fluorine surfactant to the coating composition and curing with active energy rays. A recording medium for thermal transfer recording is provided.

According to the present invention, a coating containing the above-mentioned specific (meth)acrylic acid alkyl ester polymer, a crosslinking agent, and a silicone-based or/and fluorosurfactant as main components is provided on the surface of a substrate (for example, film-like or paper-like). The recording material obtained by coating the composition and curing it with active energy rays (for example, to a thickness of 0.5 to 100 μm) is easily dyed with sublimable disperse dyes and has good color development and sharpness. It has been found that blocking properties with transfer sheets coated with disperse dyes are improved.

The (meth)acrylic acid alkyl ester polymer used in the present invention is a (meth)acrylic acid alkyl ester polymer having a substituted or unsubstituted alkyl group or a copolymer thereof. Examples of copolymerizable monomers include styrene, (meth)acrylic acid, and the like. Examples of substituents for the alkyl group include a hydroxyl group, an amino group, and a carboxyl group.

A preferred (meth)acrylic acid alkyl ester polymer contains a (meth)acrylic acid alkyl ester component of 50% by weight.
It is a polymer containing the above-mentioned amount and has a Tg of 40°C or more.

If the Tg of the polymer is less than 40°C, the transfer sheet coated with the sublimable disperse dye and the recording medium may stick to the thermal recording medium when heated, that is, a phenomenon called "sticking" may occur. Become. On the other hand, if the amount of (meth)acrylate in the polymer is less than 50% by weight, the color development by the sublimable disperse dye will be reduced.

The blending amount of the (meth)acrylic acid alkyl ester polymer is from 30 to 100 parts by weight of the mixture of crosslinking agent and polymer.
It is 90 parts by weight, preferably 40 to 85 parts by weight. If the amount of the (meth)acrylic acid alkyl ester polymer is less than 30 parts by weight, the color development by the sublimable disperse dye will be reduced, and if it exceeds 90 parts by weight, , King has become easier to appear,
The adhesion to the υ substrate, which has poor curing properties with active energy rays, decreases.

Any crosslinking agent can be used as long as it can be cured by active energy rays and has good compatibility with the alkyl (meth)acrylate polymer. However, if the radiation source is ultraviolet rays, polymerization Preferably, the functional group is at least one polyfunctional monomer having a methacryloyloxy group or an acryloyloxy group, and/or at least one monofunctional monomer. Note that the polyfunctional monomer is essential for curing the coating composition with active energy rays, but the monofunctional monomer is not essential.

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

It represents a group represented by OI (in formula C, R9 and m have the same meanings as above). ] It is preferable to use the compound represented by 30% by weight or more of the monomers and oligomers.

Oligomers represented by these general formulas have excellent curing properties when exposed to ultraviolet rays in the air, resulting in improved cupling properties when using ultraviolet rays, as well as improved stickiness and blocking properties on the surface of the coating film. However, when using monomers or oligomers that have poor curing properties when exposed to ultraviolet irradiation in the air, the surface of the coating film becomes sticky (and blocking occurs). Specific examples of the compound represented by the above general formula include dipentaerythritol tetraacrylate, dipentaerythritol pentaacrylate, dipentaerythritol hexaacrylate, tripentaerythritol interacrylate,

The amount is 0 to 70 parts by weight, preferably 15 to 60 parts by weight.

If the amount of crosslinking agent exceeds 70 parts by weight, the dyeing resistance will be good, but the dyeing resistance will be decreased.
When the amount is less than 20% by weight, a 20% increase will occur.

In such a process, the amount of energy applied to the thermal head (for thermal recording) increases and the heating temperature of the thermal head becomes high. and fluorosurfactants,

When blended in an amount of 0.01 to 10 parts by weight based on parts of 003i, blocking properties are significantly improved, and
The preferred blending amount of the silicone surfactant and/or fluorine surfactant is in the range of O,OS to 5 parts by weight, since it also improves the dye density and the smoothness of the coating. If it is less than 0.01 part by weight, the effect of improving the blocking property is small, and if it exceeds 10 parts by weight, blocking may occur more easily or the film will have a cloudy, milky appearance.

As silicone surfactants, compounds represented by the following general formula (I) or (2) are particularly effective in preventing blocking, improving dye density, and improving film smoothness.

As the fluorine-based surfactant, nonionic, cationic, anionic, or amphoteric fluorine may be used as long as it is compatible with the mixture of the crosslinking agent and the alkyl (meth)acrylate polymer and exhibits surface activity. surfactants may also be used. For example, anionic surfactants such as fluoroalkoxypolyfluoroalkyl sulfates, fluorocarbon calphone K [i, fluorocarbon carboxylic acid salts, etc., such as N-fluoroalkylsulfonamide alkylamine salts, N-fluoroalkyl ζ-doalkylamine Quaternary ammonium salts, N-fluoroalkylamide alkylamine salts.

It is particularly desirable to use nonionic surfactants in consideration of coating workability, anti-oxidation, kinging properties, improvement in dye density, and surface properties of the resulting coating.

These silicone surfactants and/or 7 and thread surfactants may be used alone or in combination.

Examples include peroxide compounds such as t-butyl Δ-oxide, and these compounds are used in one form or in a mixed system of two or more types.

The coating composition consisting of the above crosslinking agent, (meth)acrylic acid alkyl ester polymer, silicone surfactant or/and fluorine surfactant, and optionally a photopolymerization initiator is in the form of a film or paper. Coating can be applied to the base material using roll coating method, bar code method, spray coating method, gravure coating method, curtain method, bead coating method, flow method, dirag coating method, etc. However, in order to improve workability, it is necessary to add a solvent (for example, ethyl alcohol, inglobil alcohol, acetone, methyl ethyl ketone, methyl acetate, ethyl acetate, dimethyl formamide, etc.) to these compositions to achieve an appropriate coating viscosity. Better adjust.

The film thickness of the composition formed on the substrate is 0.5 to 100μ, preferably 1 to 50μ. When the film thickness becomes thinner than 0.5 μm, the diffusion of the dye reaches saturation halfway and it is impossible to dye the film in a deep color. On the other hand, if the film thickness exceeds 100 μm, blocking tends to occur during heating.

When stacking dyed films or papers, in order to prevent the transfer of the disperse dye, it is better to apply the composition that forms a dyed layer on only one side of the base feathers, but do not actively prevent the transfer of the dye. In order to prevent dyeing, it is more preferable to provide a non-migration layer on the opposite side to the dyed layer.

The composition for forming the non-migration layer includes 100 parts by weight of a monomer or oligomer mixture consisting of the polyfunctional monomer and/or monofunctional monomer described above. ! If so, a coating agent containing 0.1 to 10.0 parts by weight of the photopolymerization initiator described above can be used, but in order to sufficiently prevent dye migration due to disperse dyes, it is necessary to It is necessary that the number of molecules per molecule is 1.5 or more on average. These coating agents can also be adjusted in viscosity with a solvent, applied, and cured in the same manner as the coating composition for forming a dyed layer.

The film-like or paper-like base material used in the recording medium of the present invention may be any material that is normally used as a base material for dry transfer. Specific examples of film red paper include film-like materials such as polyester film, polypropylene film, nylon film, and vinyl chloride film; art paper mainly made of wood fiber;
Examples include paper-like paper such as acrylic paper mainly composed of acrylic fibers, / IJ ester paper, etc. In consideration of heat resistance, polyester film, acrylic paper, or art paper are preferred; Considering this, polyester film is most preferable.

These papers or films can be used as they are, or if necessary, they can be pretreated by washing, etching, corona discharge, active energy ray irradiation, dyeing, printing, etc. Good too.

In preparing the recording medium of the present invention, the above-mentioned coating composition is usually mixed uniformly 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.

Active energy rays include ultraviolet rays emitted from sources such as xenon lamps, low-pressure mercury lamps, high-pressure mercury lamps, or ultra-high-pressure mercury lamps, electron beams usually extracted from 20-2000 kV electron beam accelerators, α rays, β rays, γ rays, etc. radiation, etc.

Considering ease of handling and workability, the wavelength is 100~SOOnm.
UV radiation in the range is preferred.
