Description

BACKGROUND OF THE INVENTION
1. Field of the Art
The present invention relates to a dye intermediate, a dye and a thermal transfer sheet. More particularly, it is concerned with an intermediate capable of providing a dye excellent in the coloring density, sharpness, light fastness, safety, etc., a dye and a thermal transfer sheet excellent in the above-described properties.
2. Background Art
Various thermal transfer processes are known in the art. Among them, a sublimation transfer process has been practiced which comprises supporting a sublimable dye as a recording agent on a substrate sheet, such as paper, to form a thermal transfer sheet, putting the thermal transfer sheet on a transfer material dyeable with a sublimable dye, for example, a polyester woven fabric, and applying a thermal energy in a pattern form from the back surface of the thermal transfer sheet to transfer the sublimable dye to the transfer material.
In recent years, a proposal has been made on a process wherein various full color images are formed on paper or a plastic film through the use of the above-described sublimation type or thermal transfer system. In this case, a thermal head of a printer is used as heating means, and a number of color dots of three or four colors are transferred to the transfer material, thereby reproducing a full color image of an original by means of the multicolor dots.
Since the color material used is a dye, the image thus formed is very clear and highly transparent, so that the resultant image is excellent in the reproducibility and gradation and the quality of the image is the same as that of an image formed by the conventional offset printing and gravure printing. In this method, it is possible to form an image having a high quality comparable to a full color photographic image.
The most important problem in the thermal transfer process resides in the color density, sharpness and light fastness of the formed image, and no dye which could have sufficiently solved these problems are known in the art.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a thermal transfer sheet which, in a thermal transfer process wherein use is made of a sublimable dye, can provide a clear image having a sufficient density, the formed image being excellent in the light fastness.
The above-described object can be attained by the present invention. Specifically, the present invention provides a pyridine derivative represented by the following formula A or B, a dye produced by coupling the pyridine derivative A or B with any coupler and a thermal transfer sheet using the dye: ##STR2## wherein Z stands for an atom or atom group having a coupling capability selected from a hydrogen atom, an amino group, a halogen atom, a nitro group and a nitroso group, R.sub.1 and R.sub.2 each independently stand for a hydrogen atom or a substituted or unsubstituted alkyl group, vinyl group, allyl group, aryl group, alkoxyalkyl group, aralkyl group, alkoxycarbonylalkyl group, carboxyalkyl group, alkoxycarboxyalkyl group, substituted or unsubstituted cycloalkyl group, substituted or unsubstituted acylamino group, substituted or unsubstituted alkylsulfonylamino group, substituted or unsubstituted oxycarbonyl group, substituted or unsubstituted ureido group, substituted or unsubstituted carbamoyl group, substituted or unsubstituted sulfamoyl group, substituted or unsubstituted heterocyclic group, substituted or unsubstituted acyl, substituted or unsubstituted amino group or substituted or unsubstituted sulfonyl group, provided that R.sub.1 and R.sub.2 may combine with each other to form a ring or R.sub.1 or R.sub.2 may combine with X or Y to form a ring; R.sub.3 stands for a hydroxyl group, a halogen atom, a cyano group or a substituted or unsubstituted alkyl group, alkylformylamino group, alkylsulfonylamino group, formylamino group, allylformylamino group, sulfonylamino group, allylsulfonylamino group, carbamoyl group, sulfamoyl group, amino group, carboxyl group, alkoxy group or ureido group; and n is an integer of 0 to 3.

DETAILED DESCRIPTION OF THE INVENTION
A heat transfer sheet capable of providing a record image excellent in the coloring density, sharpness and light fastness is provided through the use of a dye having a particular structure.
The present invention will now be described in more detail with reference to the following preferred embodiments.
The pyridine derivative of the present invention is represented by the general formula A or B. For example, 50 g of 2-chloro--5-nitropyridine and 150 ml of diethylamine were placed in a sealed tube and heated at 120.degree. C. for 7 hr. Pure water was added to the precipitated crystal, and the crystal was collected by filtration and recrystallized from 300 ml of methanol to give 53 g of 2-diethylamino-5-nitropyridine (yield: 86%, melting point: 75.degree. to 76.degree. C.).
40 g of the 2-diethylamino-5-nitropyridine was subjected to catalytic reduction in one liter of methanol through the use of 2 g of 10% Pd-C. The catalyst was removed by filtration, and the filtrate was concentrated to give 32 g of 5-amino-2-diethylaminopyridine (yield: 95% oleaginous form).
The dye of the present invention can be produced by coupling the above-described pyridine derivative A or B with any known coupler and represented by the following general formula A' or B'. ##STR3## wherein R.sub.1 to R.sub.3, X, Y and n are as defined above and A stands for a residue of any coupler.
Several processes for producing the above-described dye will now be exemplified.
<SYNTHESIS EXAMPLE 1>
7 g of 2-acetylamino-4,6-dichloro-5-methylphenol and 5 g of 5-amino-2-diethylaminopyridine were dissolved in 240 ml of ethanol. 80 ml of an aqueous solution of 15.8 g of sodium carbonate and 60 ml of an aqueous solution of 11.9 g of red prussiate were successively added to the resultant solution with stirring, and the mixture was stirred at room temperature for 2 hr. Thereafter, 300 ml of water was added thereto, and the mixture was stirred for 30 min and extracted with 400 ml of ethyl acetate. The resultant organic layer was separated, washed with water, dried and removed by distillation. The residue was purified by silica gel column chromatography and recrystallized twice from ethanol to give 0.5 g of a dye represented by the following structural formula. The ultraviolet and visible absorption spectrum is shown in FIG. 3. ##STR4##
<SYNTHETIC EXAMPLE 2>
5 g of 2-propylamide-1-naphthol and 7.0 g of 5-amino-2-diethylaminopyridine were dissolved in 250 ml of ethanol. 80 ml of an aqueous solution of 15.8 g of sodium carbonate and 60 ml of an aqueous solution of 11.9 g of red prussiate were successively added to the resultant solution with stirring, and the mixture was stirred at room temperature for 2 hr. Thereafter, 300 ml of water was added thereto, and the mixture was stirred for 30 min and extracted with 400 ml of ethyl acetate. The resultant organic layer was separated, washed with water, dried and removed by distillation. The residue was purified by silica gel column chromatography and recrystallized twice from ethanol to give 3.7 g of a dye represented by the following structural formula. The ultraviolet and visible absorption spectrum is shown in FIG. 4. ##STR5##

The thermal transfer sheet of the present invention is characterized in that use is made of the above-described particular dyes. The other constitution may be the same as that in the conventional thermal transfer sheet.
The substrate sheet containing the above-described dye used in the thermal transfer sheet of the present invention may be any known one having a heat resistance and a strength to some extent. Examples of the substrate sheet include paper having a thickness in the range of from about 0.5 to 50 .mu.m, preferably in the range of from about 3 to 10 .mu.m, various types of converted paper, a polyester film, a polystyrene film, a polypropylene film, a polysulfone film, a polycarbonate film, an aramid film, a polyvinyl alcohol film and cellophane. A polyester film is particularly preferred.
The dye supporting layer provided on the surface of the above-described substrate sheet comprises a layer produced by supporting on the substrate sheet a dye selected from those represented by the general formula (I) by means of an arbitrary resin.
The binder resin for supporting the above-described dye may be any conventional one, and preferred examples thereof include cellulose resins such as ethyl cellulose, hydroxyethyl cellulose, ethylhydroxy cellulose, hydroxypropyl cellulose, methyl cellulose, cellulose acetate and cellulose acetate butyrate, and vinyl resins such as polyvinyl alcohol, polyvinyl acetate, polyvinyl butyral, polyvinyl acetoacetal, polyvinyl pyrrolidone and polyacrylamide. Among them, polyvinyl butyral and polyvinyl acetal are particularly preferred from the viewpoint of the heat resistance and the migration of a dye.
The dye supporting layer of the thermal transfer sheet of the present invention is basically comprised of the above-described material and, if necessary, additionally contains various additives known in the art.
The above-described dye supporting layer is preferably formed by adding the above-described dye, binder resin and optional components to a suitable solvent to dissolve or disperse the individual components in the solvent to prepare a coating solution or an ink for the formation of a supporting layer, coating the coating solution or ink on the substrate sheet and drying the resultant coating.
The thickness of the supporting layer thus formed is in the range of from about 0.2 to 5.0 .mu.m, preferably in the range of from about 0.4 to 2.0 .mu.m. The content of the dye in the supporting layer is preferably 5 to 70% by weight, still preferably 10 to 60 % by weight based on the weight of the supporting layer.
Although the thermal transfer sheet of the present invention, as such, is sufficiently useful for a thermal transfer application, it is also possible to further provide a surface tack eliminating layer, that is, a release layer, on the surface of the dye supporting layer. The provision of such a layer enables the tack adhesion of the thermal transfer sheet to the transfer material to be prevented during the thermal transfer, so that an image having a better density can be formed through the use of a higher thermal transfer temperature.
Regarding the release layer, a considerable effect can be attained by merely adhering an antitack inorganic powder. Further, for example, it is also possible to select a highly releasable resin, such as a silicone polymer, an acrylic polymer or a fluorinated polymer, and to provide a release layer of the selected resin having a thickness in the range of from 0.01 to 5 .mu.m, preferably in the range of from 0.05 to 2 .mu.m.
The inorganic powder or releasable polymer can exhibit a sufficient effect also when it is incorporated in the dye supporting layer.
Further, a heat resistant layer may be additionally provided on the back surface of the thermal transfer sheet for the purpose of preventing an adverse effect of heat from a thermal head.
The transfer material used for forming an image through the use of the above-described thermal transfer sheet may be any one as far as the recording face has a capability of accepting the above-described dye. When the transfer material is paper, a metal, glass, a synthetic resin or other material incapable of accepting the dye, a dye accepting layer may be formed on one surface such a material.
Means for applying a thermal energy used in the thermal transfer through the use of the thermal transfer sheet according to the present invention and the recording material may be any means known in the art. For example, a desired object can be sufficiently attained by applying a thermal energy of about 5 to 100 mJ/mm.sup.2 through the control of a recording time by means of a recording device, for example, a thermal printer (for example, a video printer VY-100 manufactured by Hitachi, Limited).
The present invention will now be described in more detail with reference to the following Example and Comparative Example. In the Examples and Comparative Examples, "parts" is by weight unless otherwise specified.
EXAMPLE
An ink composition comprising the following components for the formation of a dye supporting layer was prepared, and the ink composition was coated on a 6 .mu.m-thick polyethylene terephthalate film having a back surface subjected to tropicalization so that the coverage on a dry basis was 1.0 g/m.sup.2. The resultant coating was dried to give the thermal transfer sheet of the present invention.

When no change in the sharpness of the image was observed after this test, the light fastness was evaluated as ".largecircle."; when a slight deterioration in the sharpness of the image was observed, the light fastness was evaluated as ".DELTA."; and when a deterioration in the sharpness of the image was observed, the light fastness was evaluated as "X".
Mutagenic Test:
Ames test was conducted as an identical amest test with respect to representative examples of the intermediate of the present invention and control dyes having the same structure as that of the intermediate of the present invention, except that the ring was a pyridine ring instead of the phenyl ring.
The ames test was conducted in such a state that Salmonella TA1538 and TA98 were metabolically activated by a preincubation method (+x9mix). The dye was used in contentrations in five grades in the range of from 0 to 5 mg. Acetone was used as the solvent control. The toxicity was judged based on the maximum increase in the colony of the sample as compared with the solvent control. Specifically, when the increase in the reversion colony was twice or more as compared with that in the case of the control, the mutagenicity was judged as positive, while when the increase in the reversion colony was less than twice as compared with that in the case of the control, the mutagenicity was judged as negative. The results are given in the following Table.
