Description

The method of coloured composition that imaging is used and raising color picture ozone resistants

The application is dividing an application of the Chinese patent application No.02808008.4 that submitted on April 8th, 2002.

Technical field

The present invention relates to coloured composition that a kind of imaging that includes the azoic dyestuff of specific physical properties and ad hoc structure uses and uses thereof, inkjet ink composition (ink composite that ink-vapor recording is used) for example, a kind of ink jet recording method, a kind of hot tranfer recording material, a kind of color toner, a kind of colour filter and a kind of method that improves ozone resistants.

Background technology

The material that forms color picture has surpassed the material that forms soot-and-whitewash.They have found various uses, for example ink jet recording materials, hot tranfer recording material, electrophotographic recording material, transfer printing type photographic silver halide material, marking ink, stylus and in solid-state image pickup such as charge-coupled device (CCD) and the colour filter in indicating meter such as liquid-crystal display (LCD) and plasma display dish (PDP).

These color image recording materials and colour filter use the tinting material (dyestuff and pigment) of additive or subtractive primary to realize panchromatic duplicating or record.Yet, have the absorption characteristic that is applicable to favourable color rendering and resist the tinting material of the patience of various working conditionss or envrionment conditions also not obtain at present.

Because low material cost, at a high speed, low noise and be easy to colored record, so ink-vapor recording is popularized fast and will be further developed.Basically, ink-vapor recording is divided into the continuous processing that makes the ink droplet non-stop flight and makes the demand of the ink droplet flight method of dripping by image information signal.The machinery that forms ink droplet comprises by piezoelectric element to be exerted pressure with the piezoelectric system of spraying ink droplet, is subjected to the thermogenesis bubble with the hot system of spraying ink droplet, sound system, suck or the electrostatic system of ejection ink droplet by electrostatic force to printing ink.Jetted ink comprises water color ink, oil-based ink and solid ink (fusion).

The tinting material that is used for jetted ink requires to have (1) in printing ink solvent good solubleness or dispersiveness, and (2) form the ability of high-density image, (3) satisfactory color, (NO for example of the reactive gas in (4) anti-light, heat, the environment _x, oxidizing gas such as ozone, SO _xDeng) colour fastness, the patience of (5) anti-water or chemical substance, (6) good stationarity on medium has minimized burr, (7) stability in the printing ink goods, (8) are nontoxic, the purity that (9) are high and (10) are inexpensive.The tinting material that all these requirements are satisfied in acquisition is extremely difficult.Wish that exploitation has the oxidizing gas in favourable pinkish red color and fast light, wet, heat and the environment such as the tinting material of ozone especially always.Having the place that forms image on the medium that contains porous white inorganic pigment particulate ink receiving layer, especially to pay close attention to anti-oxidant gaseousness.

Use the color copy machine of electrophotographic system and color laser printer often to use to have dyestuff or pigment to be scattered in color toner in the resin glue as tinting material.Color toner requires to have the absorption characteristic that is applicable to favourable color rendition, high transmittance (transparency), in particular for the colour fastness of elevated projecting (OHP) and anti-various environment for use conditions.Contain the toning agent that is scattered in the pigment in the particle and be disclosed in JP-A-62-157051 (term used herein " JP-A " be meant " examine disclosed Japanese patent application), JP-A-62-255956 and JP-A-6-118715.Although have excellent photostabilization, these toning agents are difficult for molten, easily assemble, and can cause the color of transparency reduction or transmitted light to change like this.The toning agent that contains dyestuff is disclosed in JP-A-3-276161, JP-A-7-209912 and JP-A-8-123085.Although they have high transparency and color does not change, existing problems aspect photostabilization.

Thermal transfer recording system has following advantage: size is little, makes cost reduce, easy handling and maintenance, and running cost is low.The tinting material that is used for hot tranfer recording requires to have the absorption characteristic that is applicable to favourable color rendition, the balance between the stationarity after hot transfer printing performance and the transfer printing, thermostability and to the colour fastness of various factors.There are not a kind of all these requirements of satisfying in the known tinting material.For example, JP-A-60-2398 has proposed a kind of hot tranfer recording material and a kind of image formation method, wherein with a kind of thermodiffusion tinting material and the transition metal ion chelating that joins in the visual receiver media.Yet the absorption characteristic of the chelate compound of formation is unsatisfactory.And using transition metal also is problem to environment.

Colour filter requires to have high transparency, by producing with dyeing.For example, stainable photo-resist is through scheming decent exposure and develop to form the pattern of each color, and obtains colour filter with dyestuff continuous dyeing separately.As U.S. Pat 4,808,510 and JP-A-6-35182 in instruction, also by using positive resist to produce colour filter.Use the colour filter of DYE PRODUCTION to present excellent optical, have high transmittance, but limited to the patience of light and heat.Therefore need to have various resistances and the high dyestuff of transparency always.On the other hand, use method that the pigment dyestuff of anti-light and heat replaces the DYE PRODUCTION colour filter widely known to, but be difficult to obtain this optical characteristics with dyestuff.

The performance that used tinting material needs jointly in using above is the absorption characteristic that (1) is applicable to color rendition, (2) colour fastness of anti-various environment for use conditions, for example fast light, hot, wet, oxidizing gas such as ozone and chemical substance such as sulphurous acid gas and (3) big molar absorptivity.

The one-tenth colour content that has been widely used in azoic dyestuff comprises phenol, aphthols and phenyl amines.JP-A-11-209673 discloses with Japanese Patent 3020660 and has used these azoic dyestuffs that becomes colour content to obtain, and they have satisfactory color, but photostabilization is poor.Afterwards, Japanese patent application 2000-220649 had proposed to have the sunproof dyestuff of satisfactory color and raising.Yet, by known all these tinting materials of the document extremely unsatisfactory aspect the patience of the oxidizing gas of for example ozone.

When searching had the tinting material of gratifying resistance to oxidation gas such as ozone, the inventor had drawn and has used nitrogen-containing heterocycle compound as the thought that becomes colour content, abandons using the thought of conventional one-tenth colour content such as phenol, aphthols and phenyl amines.With contain pyridine and become colour content or pyrazine to become the relevant patent application of the azoic dyestuff of colour content to comprise JP-A-49-74718, EP23309 and DE 2513949, DE 2832020 and DE2525505.In these patent applications of application, do not know that these dyestuffs can be used for by imaging such as ink-vapor recordings; And it is deficiency aspect the reactive gas of disclosed these azoic dyestuffs in fast light, hot, wet and environment in these disclosed documents, and also not enough as the color of magenta dye.

Second preferred implementation

The azo-compound that can be used for coloured composition of the present invention has the oxidizing potential than the high 1.0V of SCE.Oxidizing potential is high more, and is good more.Preferred oxidizing potential is higher than the compound of 1.1V (SCE relatively).More preferably oxidizing potential is higher than the compound of 1.2V (SCE relatively).

In the research to the ozone resistants of color picture, the inventor has found to exist a relation between the oxidizing potential of the coloring compound that is used to form color picture and ozone resistants.They find out that ozone resistants can improve by the azo-compound that uses oxidizing potential to be higher than 1.0V (relative saturation mercurous chloride electrode (SCE)).They find out that also containing at least two pKa values is that-10 to 5 substituting group and the azo-compound with above-mentioned oxidizing potential show the high anti-ozone gas performance of expectation of coming in and going out.

Improve the assessed in relation between the minimum occupied molecular orbital (LUMO) of highest occupied molecular orbital (HOMO) that the ozone resistants of color picture can be by compound and ozone gas by compound with specific oxidizing potential.That is, between the LUMO of the HOMO of coloring compound and ozone, react, thereby with the coloring compound oxidation, this is considered to cause the ozone resistants of color picture to reduce.Therefore, thus ozone resistants improve to be to reduce it with the reactivity foundation of ozone by the HOMO that reduces coloring compound.

Oxidizing potential is represented the movability of electronics from the sample to the electrode.Oxidizing potential is high more, and electron migration is more little, and promptly sample is low more to the susceptibility of oxidation.About chemical structure, oxidizing potential increases with the electron-withdrawing group that adds wherein, and reduces with the electron-donating group that adds wherein.

Oxidizing potential is meant that compound in the voltammetry that is described in detail later loses the anodic current potential of its electronics.Think that oxidizing potential approximates the energy level of compound at the HOMO of its ground state.

Oxidizing potential is with DC polarogram system or cyclic voltammetric systems measurement.With sample to be determined with 1 * 10 ^-4-1 * 10 ^-6Mol.dm ^-3Concentration be dissolved in the solution of supporting electrolyte of for example sodium perchlorate in the solvent of dimethyl formamide for example or acetonitrile or perchloric acid tetrapropyl ammonium, and use SCE to measure the current potential of working electrode as reference electrode.Oxidizing potential per sample or solubleness are selected suitable electrolyte and solvent.Details with regard to these selections can be with reference to P.Delalhay, New Instrumental Methods in Electrochemistry, Interscience Publishers (1954), A.J.Bard etc., Electrochemical Methods, John Willey ﹠amp; Sons (1980) and Akira Fujishima etc., DenkikagakuSokuteiho 101-118 page or leaf Gihodo (1984).

By the influence of the potential difference between the different liqs, the resistance of sample etc., oxidizing potential is measured may differ about tens millivolts.Can use standard model (for example quinhydrones) to proofread and correct this species diversity to this, thereby guarantee the reproducibility of mensuration.

In the present invention, oxidizing potential mensuration is to use by the DC polarography to contain 0.1mol.dm ^-3The perchloric acid tetrapropyl ammonium is as supporting electrolyte and 1 * 10 ^-3Mol.dm ^-3The N of sample compound, dinethylformamide solution uses SCE as reference electrode, uses Graphite Electrodes as working electrode, and uses platinum electrode to carry out as counter electrode.

The operation that is used to obtain to have high oxidation potential comprise (i) select to have inherently high oxidation potential compound structure, (ii) add electron-withdrawing group (promptly to the optional position of compound, have the group of big Hammett substituent constant σ p value, this paper back is described).Not only from the angle of ozone resistants, and from being easy to add any electrophilic or the photoelectron group angle with the molecular designing of adjusting colour fastness, color and physicals, the dye structure of selecting to have inherently high oxidation potential is a preferred operations.

Join the optional position of compound structure when electron-withdrawing group, thereby make oxidizing potential higher, therefore reduce with the time, can use Hammett substituent constant σ p value as substituent electrophilic or measuring to Electronic Performance as the ozone of electrophilic reagent reactive.The substituting group that has big σ p value by adding can make oxidizing potential higher.

Here explain Hammett substituent constant σ p value briefly.The Hammett rule is the rule of thumb that L.P.Hammett proposed in nineteen thirty-five, thereby attempts discussing quantitatively reaction or the equilibrated influence of substituting group to benzene derivative, is considered to effective so far usually.Used substituent constant comprises σ p value and σ m value in the Hammett rule.These values can find in many general books, J.A.Dean (editor) for example, Lange ' s Handbook of Chemistry, the 12nd edition, McGraw-Hill (1979) and Kagaku-no-ryoiki, the 122nd phase special issue, the 96-103 page or leaf, Nankodo (1979).

It is-10 to 5 that the azo-compound that can be used for coloured composition of the present invention should have at least two pKa values in water, preferred-9 to 5, is more preferably-8 to 5 substituting group." the pKa value is-10 to 5 substituting group " is that the substituting group that the pKa value is the proton dissociation part of-10 to 5 compound is measured in a kind of representative in water.

The pKa value is a kind of for example at Yasuhiko Saawaki, the value of definition in the Kisokagaku CourseButuriyukikagaku 47-60 page or leaf, Maruzen (1999).The pKa value of chemical compound lot is shown in M.B.Smith ﹠amp; J.March, the 5th edition the 329th page table 8.1 of March ' s Advanced OrganicChemistry, John Wiley ﹠amp; Sons (2001), and be introduced into this paper, can obtain substituent pKa value thus.The pKa value of the compound that does not find in the document can be according to The Chemical Sociaty of Japan (editor), the method of instruction is defined as the basis acquisition with the pKa value among the 115th page of the JikkenKagaku Koza l Kihon Sosa I (the 4th edition), Maruzen (1990).Faintly acid pKa value can be according to YasuhikoSaawaki, the 50th page of Kisokagaku Course Buturiyukikagaku, and the method described in the Maruzen (1999) obtains with relative value.Because the pKa value changes with the environment of for example solvent, therefore can be according to The Chemical Sociaty of Japan (editor), the 286th page of Jikken KagakuKoza 9 Denki.Jiki (the 4th edition), the method described in the Maruzen (1991).

Notice that any substituent pKa value in the compound is subjected to the influence of structure of compound big, actual value may be with different by the value of another compound estimation like this.Although can use aforesaid method to measure the pKa value of the group that dissociates of compound, because the part except that the group that dissociates can influence this mensuration, so when this measured value of assignment for example, be not easy systematically to understand this measured value.

Therefore, in the present invention, any substituent pKa value of compound is not by to the value representation of compound practical measurement, but the conventional pKa value representation by corresponding functional group.The pKa value of the group that dissociates of the structure of the approaching group that dissociates of preferred utilization and compound similar compounds to be evaluated is estimated, so that substituting group influence or three-dimensional influence are minimized.For example, in order to explain the pKa value of the carboxyl in a certain compd A that carboxyl links to each other with phenyl ring, can use the pKa value of similar phenylformic acid (=4.2) or derivatives thereof of substituent type on the phenyl ring and position and compd A.The used pKa value of the present invention that is used for the quantitative definition compound is measured at water.

The pKa value comprises sulfo group, carboxyl, thiocarboxyl group, sulfino, phosphono and dihydroxyl phosphino-at-10 to 5 substituting group, wherein preferred sulfo group and carboxyl.

Group is expressed with non-separation form or salt form in the present invention although dissociate, and compound in fact can separate stage, non-separation state or exist with the separation/non-separation admixture of any ratio.The virtual condition of group of dissociating depends on the residing environment of compound.

The substituent quantity of pKa value between-10 to 5 is 2 or more in each molecule, preferred 3 or more, and more preferably 4 or more.The pKa value can be connected any position of azo-compound independently of one another for-10 to 5 substituting group.When these substituting groups are water soluble group, according to Kazuo Kondo (managing editor), Senshoku (the 3rd edition) about directly acting on the instruction of cellulosic fibre factor, separately is an ideal with their spaces among the TokyoDenki University Publishing Dep. (1987).

Preferably on each side of azo group-N=N-at least one is arranged, particularly two or more pKa values are substituting groups of-10 to 5.The preferred azo-compound of employing formula (5-I) representative this means Het (A ⁵) and Het (B ⁵) respectively carrying at least one, particularly two or more pKa values are substituting groups of-10 to 5.

Specific azo-compound to the raising of the ozone resistants of color picture can be by being positioned at correct position suitable dissociate group and specific oxidizing potential above-mentioned of suitable quantity influence evaluation.Think that the particular solution in the azo-compound has increased the direct degree of compound from this configuration of group.Then the azo-compound in the printing ink can be fixed on the desired location of visual receiver media.In other words, as if the dissociate this configuration of group produces a kind of mordant dyeing effect between azo-compound and visual receiver media.This is consistent with water-repellancy result among the embodiment that this paper provides later.The high water-repellancy of color picture of supposing azoic dyestuff can be estimated dyeing power so owing to the firm mordant dyeing between azoic dyestuff and the visual receiver media in waterproof test.In fact, the embodiment that this paper provides later confirms that the image with gratifying ozone resistants also has gratifying water-repellancy, and this has confirmed relation certain between mordant dyeing and the ozone resistants.

The 3rd preferred implementation

Method according to the ozone resistants of the raising color picture of the 3rd preferred implementation of the present invention is characterised in that and uses the compound of oxidizing potential than the high 1.0V of SCE.The higher compound of oxidizing potential has better result.More preferably oxidizing potential is higher than the compound of 1.1V (SCE relatively).Preferred especially oxidizing potential is higher than the compound of 1.2V (SCE relatively).

When the ozone resistants of research color picture, the inventor finds, is used to form between the oxidizing potential of coloring compound of color picture and the ozone resistants to have a relation.They find out that ozone resistants can improve by the compound that uses oxidizing potential to be higher than 1.0V (relative saturation mercurous chloride electrode (SCE)).

Improve the assessed in relation between the minimum occupied molecular orbital (LUMO) of highest occupied molecular orbital (HOMO) that the ozone resistants of color picture can be by compound and ozone gas by compound of the present invention.That is, between the LUMO of the HOMO of coloring compound and ozone, react, thereby with the coloring compound oxidation, this is considered to cause the ozone resistants of color picture to reduce.Therefore, thus ozone resistants improve to be to reduce it with the reactivity foundation of ozone by the HOMO that reduces coloring compound.

Oxidizing potential E _OxRepresent the movability of electronics from the sample to the electrode.E _OxHigh more, electron migration is more little, and promptly sample is low more to the susceptibility of oxidation.About chemical structure, E _OxIncrease with the electron-withdrawing group that adds wherein, and reduce with the electron-donating group that adds wherein.

E _OxBe meant that compound in the voltammetry that is described in detail later loses the anodic current potential of its electronics.Think E _OxApproximate the energy level of compound at the HOMO of its ground state.

Eox can easily be measured by those skilled in the art.Can reference example such as P.Delahay, New Instrumental Methods in Electrochemistry, IntersciencePublishers (1954), A.J.Bard etc., Electrochemical Methods, John Wiley ﹠amp; Sons (1980) and Akira Fujishima etc., Denkikagaku SokuteiHo, Gihodo (1984).

Oxidizing potential is with DC polarogram system or cyclic voltammetric systems measurement.With sample to be determined with 1 * 10 ^-4-1 * 10 ^-6Mol.dm ^-3Concentration be dissolved in the solution of supporting electrolyte of for example sodium perchlorate in the solvent of dimethyl formamide for example or acetonitrile or perchloric acid tetrapropyl ammonium, and use SCE to measure the current potential of working electrode as reference electrode.Oxidizing potential per sample or solubleness are selected suitable electrolyte and solvent.Details with regard to these selections can be with reference to A.Fujishima etc., Denkikagaku Sokuteiho 101-118 page or leaf Gihodo (1984).

The influence of the resistance by the potential difference between the different liqs, sample etc., oxidizing potential is measured may differ about tens millivolts.Can use standard model (for example quinhydrones) to proofread and correct this species diversity to this, thereby guarantee the reproducibility of mensuration.

In the present invention, oxidizing potential mensuration is to use by the DC polarography to contain 0.1mol.dm ^-3The perchloric acid tetrapropyl ammonium is as supporting electrolyte and 1 * 10 ^-3Mol.dm ^-3The N of sample compound, dinethylformamide solution uses SCE as reference electrode, uses Graphite Electrodes as working electrode, and uses platinum electrode to carry out as counter electrode.

Oxidizing potential is also with the structural changes of compound.Not only from the angle of ozone resistants, and from being easy to add any electrophilic or photoelectron group angle with the molecular designing of adjusting colour fastness, color and physicals, in order to reduce the reactivity with ozone, preferred selection has the compound structure of high oxidation potential inherently.

For example, in order to reduce the reactivity with electrophilic ozone, it is desirable to electron-withdrawing group is joined the optional position of compound structure, thereby make oxidizing potential higher.Can use Hammett substituent constant σ p value as substituent electrophilic or measuring to electronics.The substituting group that has big σ p value by adding can make oxidizing potential higher.

Here sketch Hammett substituent constant σ p value.The Hammett rule is the rule of thumb that L.P.Hammett proposed in nineteen thirty-five, thereby attempts discussing quantitatively reaction or the equilibrated influence of substituting group to benzene derivative, is considered to effective so far usually.Used substituent constant comprises σ p value and σ m value in the Hammett rule.These values can find in many general books, J.A.Dean (editor) for example, Lange ' s Handbook of Chemistry, the 12nd edition, McGraw-Hill (1979) and Kagaku-no-ryoiki, the 122nd phase special issue, calculate the 96-103 page or leaf, Nankodo (1979).

The maximum absorption wavelength and the half breadth that are used to characterize The compounds of this invention can easily be measured by those skilled in the art.For example can be with reference to The Chemical Sociaty ofJapan (editor), Jikken Kagaku Koza 7Bunko II the 4th edition, 175-199 page or leaf, Maruzen (1992).Specifically, can use two unit that get by quartz or glass, a dress sample solution, another adorns contrast, measures.The solvent of sample solution from can sample dissolution, estimating that wavelength zone does not absorb and too not high-volatilely selecting arbitrarily those.In the present invention, use N, dinethylformamide (DMF) is used for measuring.

As for the mensuration of the half breadth of absorption spectrum, can be with reference to Jikken Kagaku Koza 7Bunko II the 4th edition, the especially description in the 154th page.The half breadth representative of absorption spectrum is at the width of the absorption band of a half-peak absorbancy, and it is used to describe the shape of absorption band.Have the spectrum point of little half breadth, and have the spectral width of big half breadth.Because the unwanted absorption that exists in short and longer wavelength side does not have big influence to color rendition, color is preferably had the spectrographic dyestuff of less half value.Maximum absorption wavelength that the present invention is used and half breadth are to contain 5 * 10 ^-5Mol.dm ^-3Use those that path length measures as the quartzy unit of 1cm on the DMF solution of sample compound.

Having maximum absorption and half breadth under the wavelength with 500nm-580nm is that 150nm or the narrower used compound of the present invention are used as magenta dye.For color preferably, maximum absorption wavelength is preferably at 520nm-580nm, more preferably at 520nm-570nm.Half breadth is 110nm or narrower preferably, is more preferably 90nm or narrower.

Compound with above-mentioned physicals is selected arbitrarily from azoic dyestuff, quinone dyestuff, cyanine dyes, cationic dyestuff, phthalocyanine pigment, indigoide colors, fulgide dyestuff, intermolecular charge transfer dyestuff etc.Although the dyestuff of these types can be used for the present invention arbitrarily, select and be easy to synthetic the satisfy compound that oxidizing potential and color require, preferred especially azo-compound from the width of its tone.Can be used for compound of the present invention although also will describe, should describe being suitable for other different dye structure suitably, be not construed as limiting the invention with particular reference to azo-compound.

Not only, can obtain to satisfy compound about the condition of oxidizing potential by above-mentioned actual oxidation potential measurement but also by molecular designing based on chemical structure.The oxidizing potential of known compound is relevant with the energy level of compound H OMO, as (editors) such as Manabu Seno-o, Daigakuin Buturikagaku (Chu), the 534-536 page or leaf, KodanshaScientific (1992) and Yasuhiko Saawaki, instruct in the Kisokagaku CourseButuriyukikagaku 187-189 page or leaf, Maruzen (1999).Therefore, can make the oxidizing potential of compound near desired level by adjusting the HOMO level.

Before the HOMO level of adjusting compound, need obtain this HOMO level by any known technology.The HOMO level of compound can be by its oxidizing potential or by the molecular orbital method backwards calculation.Up-to-date molecular orbital method and details thereof are described in The ChemicalSociaty of Japan (editor), kikan Kagaku Sousetu No.46 Koseido BunshiSekkei to Shinsozai Kaihatsu-Kinokagakuno Shintenkai wo Mezashite-. 65-96 page or leaf, Japan Scientific Societies Press (2000) and Sumio Tokita, Electronics Kanren Shikiso-Genjo to Shorai Tenbo-20-25 page or leaf, CMC (1988).Although wish to obtain suitable calculation result, can use simpler calculating easily according to required tolerance range by accurate as far as possible Molecular Orbital Calculation.

With reference to substituting group influence and colour developing structure the structure of azo-compound and the relation of HOMO level thereof are discussed.Makoto Ohkawara etc., Kinousei Shikiso, the 39-42 page or leaf, Kodansha Scientific (1992), Makoto Ohkawara etc., Kinousei Shikiso noKagaku, 43-45 page or leaf, CMC (1981) and Sumio Tokita, Kinousei Shikiso noBunshi Sekkei-PPP Bunshikidoho to sono katuyo, 89-108 page or leaf, Maruzen (1989) have described the relation of substituting group influence with absorbing wavelength skew and orbital energies level.Be understood that this HOMO level can adjust by any substituting group is joined the position with big HOMO coefficient.That is, add electron-withdrawing substituent and make the HOMO level reduce, adding increases the HOMO level to electron substituent group.

When the oxidizing potential of a certain compound does not reach the scope of the present invention's definition, can improve desired level by adding substituting group according to the molecular designing guide of being instructed.In this case, by using aforementioned Hammett substituent constant σ p value can select suitable substituents.In order to understand molecular orbital(MO), be important to understanding the HOMO coefficient by molecular orbital method.Yet, certain restriction is arranged by substituting group influence raising.Easily expect, add many substituting groups and will be difficult to synthetic dyestuff.And replacement is accompanied by color change, makes it be difficult to satisfy the requirement of oxidizing potential and color.Only by in known compound, add substituting group may, still can be very difficult to realize purpose of the present invention.Owing to, therefore recognize and to start with from colour developing structure itself by simply utilizing the free difficulty of also adjusting the HOMO level of compound widely of substituent influence.

The colour developing structure is discussed then.Colour developing structure or can use nitrogen benzide structure (it is a basic structure) perhaps can be one to have heterocyclic heterocycle azo structure.Think and not only answer the controlled oxidation current potential, and should control absorption characteristic, therefore colour developing structure optimizing Billy is fallen in the specified range with the easier physicals that makes of substituent effect.Promptly, expect easily, when select to have minimize the HOMO level and with the colour developing structure of the approaching color of required color when adding substituting group with the basic structure of the color of oxidizing potential with adjustment and adjustment, compare with the adjustment that only depends on above-mentioned substituting group influence, the degree of freedom of molecular designing will be widened.From this angle, assert preferred heterocycle azo type compound.

Makoto Ohkawara etc., Kinousei Shikiso, the 42nd page, KodanshaScientific (1992) has especially shown the use heterocycle, particularly sulfur heterocyclic ring makes the example of absorbing wavelength to longer wavelength side skew.Think that utilizing this color development system to widen selects available substituent degree of freedom, makes its easier design can realize the compound of the object of the invention then.

Except the one-piece construction and substituting group influence of color development system, the other factors that influences the color development system of dyestuff comprises intermolecular and intramolecularly effect, solvent effect, tautomerism, acid-alkali balance, three-dimensional influence etc., as Kinousei Shikiso no Kagaku, the 58-63 page or leaf is described in the CMC (1981).

Design has an above-mentioned half breadth in its absorption spectrum compound is given the color picture of satisfactory color., instruct among the Maruzen (1982) at Chemical Seminar 9 ColorChemistry 150-161 pages or leaves as Sumio Tokita, color always not only is subjected to the influence of electron energy level, and is subjected to the influence of molecular vibration or rotation.Therefore wish that the influence that reduces because of molecular vibration or rotation will make absorption band narrower and sharper, and half breadth is narrower.The method that reduces molecular vibration or rotate influence of color comprises to the three-dimensional big substituting group of correct position adding, thus the rotation of inhibition any key.

Confirm that by above-mentioned test and observation the present invention obtains specific oxidizing potential and half breadth combination the color picture of anti-ozone gas and color excellence.The compound that can be used for the combination with specific oxidizing potential and half breadth of the present invention is the azo-compound of formula (7) representative preferably:

To require the full content of each foreign patent of foreign priority to add this paper by reference among the application, as statement in full.

Prepare ink sample 6-202 to 6-208 in the mode identical, just replace oil-soluble compounds 6-(33) with the oil-soluble compounds shown in the following table 6-2 with ink sample 6-201.Picture record and evaluation

Waxy luster printing paper (ink-jet developing out paper level derives from Fujiphoto) ink-jet printer (PM-700C derives from Cisco's Epson) writes down an image with each ink sample 6-201 to 6-208.Estimate color, paper dependency, water-repellancy, photostabilization and the ozone resistants of the image of record in accordance with the following methods.Gained the results are shown in table 6-2.

1) color

With the reflection spectrum of 10nm wavelength interval at the area test image of 390-730nm, and with CIE 1976L ^*a ^*b ^*The color space system is basic calculation a ^*And b ^*Value.Preferred magenta tone is defined as follows, and color that should image is divided into the A-C level according to following standard.

Preferred a ^*Value: 76 or bigger

Preferred b ^*Value :-30 to 0

A:a ^*And b ^*Value is all in preferable range separately.

B:a ^*And b ^*One of value is in its preferable range.

C:a ^*And b ^*Value is not all in preferable range separately.

2) paper dependency

The tone of the image that forms separately on the paper with the tone of the image that forms on the waxy luster printing paper and plain paper copier (PPC) is compared.Difference between two is little, illustrates that the paper dependency is little, is decided to be A (satisfactory), and difference is big is decided to be B (poor).

3) water-repellancy

With the waxy luster printing paper that is formed with image thereon under room temperature dry 1 hour, in water, soaked for 30 seconds then, and seasoning under room temperature.Observe printing ink image become mildewed thorn and general
