Description
USE OF MIXED GLASS PIGMENTS OF THE SERIES OF
QUINACRIDONE IN TONERES AND REVELATORS
ELECTROFOTOGRAFICOS, VARNISHES IN POWDER AND INKS FOR PRINTING BY INK JETS
The present invention relates to the use of new types of mixed crystal pigments in toners and electrophotographic developers, powder coatings and inks for ink jet printing (Ink-Jet). In electrophotographic recording processes, a "picture of latent charges" is generated on a photoconductive element. This "image of latent charges" is revealed by the application of an electrostatically charged toner (also known as a toner), which is then transferred, for example, to paper, textile goods, films or synthetic materials, and is fixed, for example, by the action of pressure , radiation, heat or solvents. Typical toners are powder toners of one or two components (also known as one- or two-component developers), and special toners are also used, such as, for example, magnetic or liquid toners, latex toners and toners. polymerization. A measure for the quality of a toner is its specific charge q / m (charge per unit mass). Together with the sign and the magnitude of the electrostatic charge, a decisive quality criterion is, above all, the rapid achievement of the magnitude of the desired load and the constancy of this charge during a prolonged period of activation time. In addition, toner insensitivity to climatic influences, such as temperature and humidity, is another important criterion for additional suitability. Toners that can be charged both positively and negatively are used in photocopiers, laser printers, LED printers (Light Emitting Diodes), LCS (Liquid Crystal Shutter = liquid crystal shutters) or other digital printers on an electrophotographic basis, depending on the type of the procedure and the device. i o In order to obtain electro-photographic toners or developers with charge or positive or negative, agents for the control of the loads are added frequently. As a color-generating component (chromogen), typically colored organic pigments are used in the toners. The colored pigments have, because of their insolubility in the medium of
In this case, there are considerable advantages over dyes, such as, for example, better thermostability and fastness to light. Based on the principle of "subtractive color mixing", with the help of the three primary colors, yellow, cyan and magenta, you can reproduce the entire spectrum of colors that are visible to the human eye.
2 o Only when the respective primary color meets exactly defined color requirements, an exact reproduction of the color is possible. In another case, some color tones may not be reproduced, and the color contrast is not sufficient.
In the case of toners of all colors, the three yellow, cyan and magenta toners must be exactly matched to each other, as well as to the precisely defined chromatic requirements, also in terms of their triboelectric properties, since they are transmitted consecutively in the same device. It is known that coloring agents are able to influence persistently on the triboelectric charge of toners. Because of the various triboelectric effects of the coloring agents and the influence, in part very pronounced, on the ability of the toners to be charged, it is not possible to simply add the coloring agents to a basic recipe for a toner, once it has been processed. Rather, it may be necessary to elaborate a recipe for each coloring agent, for which the type and quantity of the agent for the control of the loads must be specially established., what is needed. This procedure is correspondingly expensive and then, in the case of color toners for a process ink, still contributes additionally to the difficulties that have already been described above. Furthermore, it is important for the practice that the coloring agents possess a high thermostability and a good dispersibility. The typical temperatures of incorporation of the dyes in the toner resins are between 100 C and 200 C in the case of using kneaders or extruders. Correspondingly, a thermostability of 200 C, better than 250 C is a great advantage. It is also important that the thermostability is guaranteed for a prolonged period of time (approximately 30 minutes) and in different systems of binding agents. Typical binding agents for toners are polymerization, polyaddition and polycondensation resins, such as styrene, styrene and acrylate resins, styrene and butadiene, acrylate, polyester, phenol and epoxide resins, polysulfones or polyurethanes, individually or in combination. Fundamentally, there is a need for colored pigments, which have as high a transparency as possible, a good dispersibility and a small electrostatic effect, if possible neutral triboelectric. By a "neutral triboelectric proper effect" it is understood that the pigment does not manifest as far as possible any impact on the electrostatic charge of the resin itself and easily follows a defined adjustment of the charges, eg by means of an agent for the control of the charges. Transparency is of paramount importance, since when copying or printing in all colors, the yellow, cyan and magenta colors are copied or printed respectively on one another, with the order of succession of colors depending on the apparatus. If, then, a color above is not sufficiently transparent, the color below it may not be sufficiently translucent and color reproduction distorts. When copying or printing on sheets from above (overhead), transparency is even more important, since in this case a defective transparency even of only one color makes all the projection of the images appear gray. The present invention was based on the mission of providing color pigments for use in toners and electrophotographic developers, powder coatings, inks for ink jet printing, color filters and fibers with electret, which meet the above requirements. The problem posed by this mission was solved surprisingly by the use of the quinacridone mixed crystals defined below. The object of the present invention is the use of mixed crystal pigments of the quinacridone series, consisting of a) 85 to 99% by weight, especially 87 to 95% by weight, of unsubstituted quinacridone in the phase, which has the general formula (I),
wherein R and R 'signify hydrogen atoms, and from b) 1 to 15% by weight, especially 5 to 13% by weight, of one or more substituted quinacridones having the general formula (I), wherein the substituents R 1 and R 2 are the same or different and represent chlorine, bromine or fluorine atoms, or C 1 -C 4 alkyl, C 1 -C 4 alkoxy or carboxamido groups, which may be substituted with C C β alkyl groups, and R 1 may additionally be hydrogen, quality of coloring agents in toners and electrophotographic developers, powder coatings, inks for ink jet printing, fibers with electret and color filters. Mixtures of quinacridones consisting of 85 to 99% by weight of quinacridone unsubstituted in the phase, and 1 to 15% by weight of one or more, especially 1 or 2, quinacridones substituted in various ways, form crystals under certain conditions mixed, which are also called solid solutions. By "mixed crystals" is meant that one or more component (s) added to a crystalline phase, most often in a non-stoichiometric ratio, and the host compound, crystallize in a common lattice. The X-ray diffraction pattern of a mixed crystal presents only the reflections of the crystalline lattice - sometimes enlarged - of the host compound or of a similar or clearly distinct crystal lattice, while in the X-ray diffraction diagram of the corresponding Mechanical mixing the reflections of all the components appear. In the mixed crystal pigments used according to the invention, substituted (b) quinacridones of the formula (I) are preferred, wherein R 1 signifies hydrogen, chlorine atoms or methyl or carboxamido groups, and R 2 means chlorine atoms or methyl groups or carboxamido. The color properties of the mixed crystal pigments according to the invention differ considerably from those with the corresponding mechanical blends of the individual components. These have, in particular, shades of purer colors and have higher coloring forces. In addition, color tones can be obtained that can not be adjusted with the individual components or with the mixed crystals known from the prior art, especially in the region of reddish violet. The fastnesses are excellent. The mixed crystal pigments described above can be prepared by cyclizing the 2,5-dianiino-terephthalic acid which forms the basis of compound a) and the substituted terephthalic acid (s) which constitutes ) the base of the compound (b), in a ratio of from 85: 15 to 99: 1, especially from 87: 13 to 95: 5, in the presence of a polyphosphoric acid and / or esters of polyphosphoric acids, hydrolyzing under pressure the mixture from the ring closure, which occurs after the cyclization, with water or diluted phosphoric acid, at a temperature of at least 110 C, preferably from 110 to 180 C, particularly preferably from 135 to 165 C , and then isolating the mixed crystal pigment, optionally after a fine division step and / or after a finishing treatment. A quantity of 3 to 10 times higher, preferably 3 to 5 times higher, amount of a polyphosphoric acid or its methyl ester, based on dianilino-terephthalic acid, is generally used as the ring closure agent. The P2O5 content of the polyphosphoric acid or its ester is preferably between 80 and 85% by weight, preferably between 83 and 85% by weight, corresponding to a phosphoric acid equivalent of 110 to 120%. Larger quantities of the ring closure agent can be used, but this is not necessary in general. The ring closure temperature is generally 80 to 150 C, preferably 120 to 140 C. In the ring closure reaction, inert solvents such as, for example, aromatic hydrocarbons may also be present. The time that passes until the total cyclization is usually 0, 5 to 24 hours, but most of the time only from 1 to 2 hours. The ring closure mixtures which occur after cyclization are hydrolysed under pressure at a temperature of at least 110 C with water or dilute phosphoric acid, optionally in the presence of an inert organic solvent under the reaction conditions, e.g. eg aromatic hydrocarbons. For hydrolysis, water or dilute phosphoric acid is used. In such case, the ring closure mixture is metered in under pressure into the water or diluted phosphoric acid. However, you can also proceed in the reverse way. The hydrolysis can be carried out in a continuous or batchwise regime. Advantageously, it is carried out continuously in a static mixer. Generally, referred to the polyphosphoric acid, a greater amount in 2 to 10 times of water or diluted phosphoric acid will be used. The duration of the hydrolysis is dependent on the rate of metered addition of the ring closure melt, for example 0.5 to 24 hours, preferably 0.5 to 5 hours. Through the choice of dianilino-terephthalic acids, the conditions of ring closure and hydrolysis at high temperatures, pigments of mixed crystals suitable for use are obtained immediately after hydrolysis, which can be isolated according to methods usual It may be advantageous to subject the finely divided mixed crystals, which have thus been obtained (in the present idiomatic idiom, hereinafter referred to as "prepigments"), to a finishing treatment at elevated temperatures, or first of all to produce coarse pigments of mixed crystals with coarse crystallinity, which are advantageously subjected to a fine mechanical division, and which directly or after a finishing treatment are transformed into a pigment form suitable for use. The mixed crystal pigments, optionally after intermediate isolation, are subjected to a subsequent treatment with or without addition of solvents at a temperature of 50 to 2001 C and, after having separated the liquid medium, they are isolated. The liquid medium can preferably have an alkaline pH value, for example a pH of 7.5 to 13. The coarse pigments of mixed crystals with coarse crystallinity are subjected to a fine fine mechanical division and then the mixed crystal pigments obtained in in this case they are isolated in the usual way or the mixed crystal pigments which have been obtained in this case, possibly after an intermediate insulation, are subjected to a finishing treatment, as previously described, and after having separated the liquid medium, are isolated. The fine division can be carried out by dry or wet milling. Preferably, a wet grinding with high energy input is carried out, since the crude pigment of mixed crystals does not have to be dried for this purpose. For dry milling, all discontinuous and continuous oscillating or rolling mills are suitable, and for wet milling all ball mills with stirring, rolling and discontinuous and continuous oscillating, as well as kneading machines are suitable. In order to improve the color properties and to achieve certain coloristic effects, solvents, pigment dispersants, surfactants, defoamers, extenders and other additives can be added at any point of the process. Mixtures of these additive materials can also be used. Surfactants which are to be used in the process are, for example, cationic, anionic or nonionic surfactants, preferably taurides of fatty acids, fatty acid sarcosides, (fatty alcohol) -polyglycol ethers, esters of (fatty alcohol) - polyglycols, alkyl polyglycol ether sulfates, (alkyl phenol) polyglycol ethers, alkane sulphonic acids and their salts, (alkyl phenyl) sulphonic acids and their salts, and (alkylphenol) -polyglycol ether sulfates. As pigment dispersants, which can be applied in the process, compounds having the general formula (II) are used
wherein P represents a radical with the valence m of a linear quinacridone of the general formula (I), in which R1 and R2 are the same and represent hydrogen atoms or methyl groups, X represents a group of the formula (III) -COOM (III) or a group of the formula (IV) -SO3M (IV) in which M denotes the hydrogen ion H + or the equivalent Mr r of a cation of a metal with the valence r, where r is the case corresponding then coincidentally one of the numbers 1, 2 or 3, as defined for example L1 +, Na1 +, K1 +, Mg2 +, C2 +, Sr2 *, Ba2 +, Mn2 +, Cu2 +, Ni2 +, Co2 +, Zn2 +, Fe2 +, Al3 +, Cr3 + or Fe3 +; or an ammonium ion or an alkyl ammonium ion, or X means a phthalimido-methylene group or a sulfonamido group. For each unit of weight of crude pigment, prepigment or pigment of mixed crystals, a total of between 0.1 and 20% by weight, preferably between 3 and 10% by weight of surfactants and / or pigment dispersants can be suitably added in total. Preferred organic solvents, which can be used in one or more stages of the preparation process, are alkanols, especially ethanol, propanoles, butanols and pentanols; amides of carboxylic acids of an aliphatic nature, in particular formamide or dimethylformamide; cyclic carboxylic acid amides, in particular N-methyl-pyrrolidone; aromatic hydrocarbons, such as, for example, toluene, xylenes or ethylbenzene; chlorinated aromatic hydrocarbons, such as, for example, chlorobenzene and o-dichlorobenzene. It was surprising and unpredictable that pure glass pigments of mixed crystals were obtained by high temperature hydrolysis, whereas according to US Pat. No. 3,160,510 pigments of quinacridone mixed crystals (and not mixtures) are obtained only when the unsubstituted quinacridone is contained in a clearly lower proportion than in the case of the present invention. In addition, according to the data of US Pat. No. 4,099,980, in the case of the solvolysis of ring closure mixtures with the aforementioned composition, mixed crystal pigments result in the phase of the unsubstituted quinacridone, while that in accordance with the present process result in pigments of mixed crystals, which occur in the phase. The mixed crystal pigments obtainable in accordance with the present invention are distinguished by outstanding color and rheological properties, especially by a high flocculation stability, easy dispersibility, good gloss performance and high coloring strength. In comparison with the mixed crystals hitherto known, such as, for example, European Patent Documents EP-A2-247,576 and EP 0 822 560 or EP 0 827 037, the use of the present mixed crystals of quinacridone leads to properties clearly improved colors in the toner. The toner, with the same concentration of the pigment used, shows a higher coloring force, a higher transparency and a more pure color tone. The electrostatic influence of the binder system is small and thus makes it possible to easily fine-tune the desired triboelectric load, for example by means of charge control agents. In addition, the preparation of the coloring agent in an environmentally friendly way leads to a more favorable overall ecological balance of the toner in colors. In addition to being used in toners and electrophotographic developers, the present mixed crystals can also be used as coloring agents in powders and varnishes, especially in triboelectrically or electrokinetically projected powder coatings, as they are applied to the surface coating of base objects, example, metals, wood, textiles, paper or rubber. The powder varnish or powder receives its electrostatic charge usually in accordance with one of the following two procedures:
a) In the corona discharge process, the powder or powder varnish is conducted in front of a device charged for corona discharge and at the same time charged, b) in the triboelectric or electrokinetic process, the principle is used of the electricity generated by friction. As resins for powder coatings, epoxy resins, polyester resins containing carboxyl and hydroxyl groups, polyurethane and acrylic resins are typically employed, together with the usual hardening agents. Resin combinations also find use. Thus, for example, epoxy resins are frequently used in combination with polyester resins containing carboxyl and hydroxyl groups. In addition, the improved triboelectric influence of the coloring agent can lead to the improvement of the properties of the electret in dyed (pigmented) electret materials, based on the typical electret materials in polyolefins, halogenated polyolefins, polyacrylates, poly (acrylonitriles), polystyrenes or fluorinated polymers, such as for example polyethylene, polypropylene, poly (tetrafluoroethylene) and those of perfluorinated ethylene and propylene, or in polyesters, polycarbonates, polyamides, polyimides, poly (ether ketones), in poly (arylene sulfides), especially poly (phenylene sulphides), in polyacetals, cellulose esters, poly (alkylene terealates) as well as mixtures of these polymers. Electret materials have numerous sectors of use and can acquire their load by means of a corona or triboelectric loading operation (bibliography: GM Sessler, "Electrets", Topics in Applied Physics, volume 33, Springer Publishing, New York, Heidelberg , 20th edition, 1987). In addition, the enhanced triboelectric influence of the coloring agent can lead to improved separation performance of stained (pigmented) polymers, which are separated according to electrostatic separation procedures (Y. Higashiyau, J. of Electrostatics, 30, pages 203-212. , 1993). Correspondingly, the triboelectric proper effect of the pigments is also important for mass dyeing of synthetic materials. Likewise, the triboelectric proper effect is important in process and elaboration stages in which intense contact with friction is reached, such as, for example, spinning processes, sheet stretching processes or other forming processes. The present mixed crystals can be coloristically colored by mixing with other pigments. The mission is often to colorize the color tone in toners in electrophotographic colors, triboelectrically projected powder coatings or inks for ink jet printing and adapt it to the specific requirements for the application. For this purpose, other organic color pigments, inorganic pigments and dyes are especially recommended. Preferably, for coloring the color tone, other organic color pigments are used in mixtures with the mixed crystals of quinacridone in concentrations of between 0.01 and 50% by weight, preferably between 0.1 and 25% by weight, and particularly preferably between 0.1 and 15% by weight, based on mixed crystals. In this case, the pigments in additional organic colors can be taken from the group of azo pigments or polycyclic pigments. In an especially preferred variant, a bluish magenta quinacridone mixed crystal can be colored by types of yellowish or carmine pigments, such as for example P.R. 146, P.R. 207, P.R. 209, P.R. 186 or P.R. 48 in the sense of a mixture of 2 components. Mixtures of multiple components are also suitable. Greater steps of color tones are possible for example when using orange-colored pigments such as P.O. 62, P.O. 36, P.O. 34, P.O. 13, P.O. 43 o P.O. 5, or yellow pigments such as P.Y. 12, 13, 17, 83, 155, 180, 185 or 97. The mixtures can be prepared in the form of powders, by mixing press cakes, spray-dried press cakes, master batches, as well as by dispersion (extrusion , kneading, processes in roller mills, bead mills, Ultraturrax) in the presence of a support material or vehicle in solid or liquid form (inks on aqueous and non-aqueous basis) as well as by waterlogging (flushing) in the presence of a material of support or vehicle. If the coloring agent is used with high proportions (>; 5%) of water or a solvent, the mixing can then also proceed in the presence of elevated temperatures and in a manner supported by a vacuum. Especially in order to increase the brightness as well as in part simultaneously for the hue of the color tone, mixtures with organic dyes are recommended. As such, preference can be given to: water-soluble dyes, such as, for example, direct dyes, reagents and acids (Direct, Reactive and Acid Dyes), as well as solvent-soluble dyes, such as, for example, dyes in solution, dyes in dispersion and vat dyes (Solvent Dyes, Disperse Dyes and Vat Dyes). As individual examples, mention will be made of: C.l. Reactive Yellow 37, Acid Yellow 23, Reactive Red 23, 180, Acid Red 52, Reactive Blue 19, 21, Acid Blue 9, Direct Blue 199, Solvent Yellow 14, 16, 25, 56, 64, 79, 81, 82, 83: 1, 93, 98, 133, 162, 174, Solvent Red, 8, 19, 24, 49, 89, 90, 91, 109, 118, 119, 122,
127, 135, 160, 195, 212, 215, Solvent Blue 44, 45, Solvent Orange 60, 63, Disperse Yellow 64 and Vat Red 41. Dyes and pigments with fluorescent properties can also be used, such as 7LuminoIe (Riedel- De Haen), in concentrations of 0.0001 to 30% by weight, preferably from 0.001 to 15% by weight, very particularly preferably comprised between 0.001 and 5%, based on the mixed crystals, for example in order to prepare safe toners against counterfeits. Inorganic pigments, such as for example TiO2 or BaSO4, serve to lighten the color in mixtures. In addition, certain mixtures of quinacridone mixed crystals with pigments are suitable for generating effects, such as, for example, pigments to produce pearlescent luster, pigments of Fe2O3 (7 Paliochrome) as well as pigments based on cholesteric polymers which, depending on the angle of observation, provide different impressions color. The mixed crystals used according to the invention can also be combined with numerous agents for the control of the loads, which control those of positive or negative sign, in order to achieve good capacities for loading in application techniques. It is also possible a simultaneous use of agents for the control of positive and negative charges. Possible agents for the control of fillers are, for example: triphenylmethanes; ammonium and imonium compounds; mineral compounds; fluorinated ammonium compounds and fluorinated imonium; amides of bis-cationic acids; polymeric ammonium compounds; diallylammonium compounds, aryl sulfide derivatives; phenol derivatives; phosphonium compounds and fluorinated phosphonium compounds; calix (n) arenes; bound oligosaccharides in the form of rings (cyclodextrins) and their derivatives, especially their derivatives of esters containing boron, inter-polyelectrolyte complexes (IPECs); salts of polyesters; complex compounds with metals, especially complexes of salicylates with metals and salicylates with non-metals; complexes of -hydroxycarboxylic acids with metals and non-metals; benzimidazolones; azines, thiazines or oxazines, which are exposed in the Color Index as pigments, dyes in solution (Solvent Dyes), basic dyes (Basic Dyes) or acid dyes (Acid Dyes). Examples of agents for the control of fillers, which can be combined individually or in combination with the mixed crystal pigment according to the invention, are: triarylmethane derivatives such as, for example: Pigment Blue 1, 2: 2 , 3, 8, 9, 9: 1, 10, 10: 1, 11, 12, 14, 18, 19, 24, 53, 56, 57, 58, 59, 61, 62, 67 of the Color Index, or example the Solvent Blue 2, 3, 4, 5, 6, 23, 43, 54, 66, 71, 72, 81, 124, 125 of the Color Index, as well as the triarylmethane compounds listed in the Color Index with the names of Acid Blue and Basic Dye, provided they are appropriate in terms of thermal stability and processability, such as, for example, Basic Blue 1, 2, 5, 7, 8, 11, 15, 18, 20, 23, 26, 36, 55, 56, 77, 81, 83, 88, 89 of the Color Index, the Basic Green

In this case, the pigment of mixed crystals as well as the agents for the control of the aforementioned fillers are added in the form of dry and ground powders, dispersions or suspensions, for example in organic and / or inorganic solvents, of a press cake (which can be used eg for the so-called waterlogging process), spray-dried press cakes, as described below, batches, preparations, pastes pastes, as a compound applied on appropriate supports, such as eg ground of infusoria (Kieselgur), T0O2 or AI2O3, from an aqueous or non-aqueous solution or can be added in another form. The content of the mixed crystal pigment in the press cake and in the master batch is usually between 5 and 70% by weight, preferably between 20 and 50% by weight. In addition, the mixed crystal pigment can also be used as a highly concentrated press cake, especially as a spray dried press cake, the pigment content being in this case between 25 and 95% by weight, preferably between 50 and 95% by weight. 90% by weight. The preparation of the spray dried press cake can be carried out according to customary methods.
The magnitude of the electrostatic charge of the electrophotographic toners or powder varnishes, in which the pigment according to the invention is homogenously incorporated, can not be predicted and is measured with the aid of conventional test systems under the same conditions (same dispersion times, equal particle size distribution, same particle shape) at approximately 20 C and a relative humidity of 50%. The operation of electrostatically charging the toner is performed by swirling with a vehicle (carrier), with a standardized share in the crushing (3 parts by weight of toner by 97 parts by weight of vehicle, on a rolling bench (150 revolutions per minute Then the electrostatic charge (JH Dessauer, HE Clark, "Xerography and related Processes", Focal Press, NY, 1965, page 289) is measured at a conventional measuring station.; J.F. Hughes, "Electrostatic Powder Coating", Research Studies Press Ltd. Letchworth, Hertfordshire, England, 1984, chapter 2). The triboelectric projection of the (varnishes in) powders is carried out with a projector with a standardized projection tube and a star internal bar, at a maximum flow rate of the powder with a projection pressure of 3 bar. The object that has been subjected to projection is hung for it inside a projection cabin and is subjected to projection from a distance of approximately 20 cm directly from the front, without additional movement of the projector apparatus. The respective charge of the sprayed powder is then measured with a "measuring device for the measurement of the triboelectric charge of powders" of the entity Intec (Dortmund). For measurement, the measuring antenna of the measuring device is held directly inside the dust cloud that comes out of the projector. The intensity of current that is established from the electrostatic charge of a powder varnish or a powder is indicated in microamps (A). The rate of deposition or separation is then determined in% by differential weighing from the sprayed and deposited powder varnish. The transparency of the pigment of quinacridone mixed crystals in toner binding agent systems is investigated as follows: In 70 parts by weight of a crude binder (consisting of 15 parts by weight of the respective resin for toner and 85 parts by weight) weight of ethyl acetate) are incorporated by stirring with a dissolving apparatus 30 parts by weight of the pigmented test toner (for 5 min at 5,000 rpm). The binder agent for test toner thus produced is applied with a doctor blade to a conventional pigment binder produced in the same way, with a manual coater on an appropriate paper (eg, letterpress printing paper). An appropriate size of the doctor blade is, for example, the K bar N3 (= thickness of the applied layer with a scraper 24 m). The paper, for the best determination of the transparency, has a black bar printed, the transparency differences are determined in dL values according to DIN 55,988, or it is evaluated according to the test prescription Marketing Pigmente, Clariant GmbH "Visuelle und Farbmetrische Bewertung von Pigmenten "edition 3, 1996 (n1 1/1). In addition, quinacridone mixed crystal pigments were found to be suitable as coloring agents in inks for ink jet printing on an aqueous basis (including microemulsion inks) and on a non-aqueous (solvent-based) base as well as in the inks that work according to the hot melt principle. The inks in microemulsion are based on organic solvents, water and eventually an additional hydrotrope (interface mediator). The inks on a non-aqueous base contain essentially organic solvents and optionally a hydrotropic substance. Inks for hot melt processes are mostly based on waxes, fatty acids, alcohols or sulfonamides, which are in the solid state at room temperature and which are converted to the liquid state upon heating, the preferred margin being located of fusion between about 60 C and about 140 C. Also subject to invention is an ink for hot melt jet printing, which consists essentially of 20 to 90% by weight of a wax and of 1 to 10% by weight of the pigment of quinacridone mixed crystals. In addition, contents of from 0 to 20% by weight of an additional polymer (as "dye solubilizer"), from 0 to 5% by weight of a dispersing agent, from 0 to 20% by weight of a modifying agent can be found. of the viscosity, from 0 to 20% by weight of a plasticizer, from 0 to 10% by weight of a tackifier, from 0 to 10% by weight of a transparency stabilizer (which, for example, prevents crystallization of the waxes) as well as from 0 to 2% by weight of an antioxidant. Typical additive materials and adjuvants are described, for example, in US Pat. No. 5,560,760. The subject of the present invention are also liquids for ink jet recording, which contain one or more of the quinacridone mixed crystal pigments. The finished recording liquids generally contain in total from 0.5 to 15% by weight, preferably from 1.5 to 8% by weight (calculated on a dry basis) of pigments of quinacridone mixed crystals. The microemulsion inks contain from 0.5 to 15% by weight, preferably from 1.5 to 8% by weight, of a pigment of quinacridone mixed crystals, from 5 to 99% by weight of water and from 0.5 to 94.5% by weight of an organic solvent and / or a hydrotrope compound. The "solvent-based" ink jet printing inks preferably contain from 0.5 to 15% by weight of a pigment of quinacridone mixed crystals, from 85 to 94.5% by weight of an organic solvent and / or hydrotrope compounds.

As hydrotrope compounds, optionally also serving as solvents, for example, formamide, urea, tetramethyl urea, caprolactam, ethylene glycol, diethylene glycol, triethylene glycol, polyethylene glycol, butyl glycol, methyl cellosolve can be used. , glycerol, N-methyl-pyrrolidone, 1,3-diethyl-2-imidazolidinone, thiodiglycol, sodium benzene sulfonate, sodium xylene sulphonate, sodium toluene sulfonate, sodium cumene sulfonate, sodium dodecyl sulfonate , sodium benzoate, sodium salicylate or sodium butyl monoglycol sulfate. In addition, the recording liquids according to the invention can also contain customary additive materials, for example preserving agents, surface-active substances, cationic, anionic or non-ionogenic (surfactants and wetting agents), as well as agents for viscosity regulation, polyvinyl alcohol, cellulose derivatives, or water-soluble natural or artificial resins such as smoke-forming agents (film formers) or binders in order to increase the adhesion and abrasion resistance. Amines, such as, for example, ethanol-amine, diethanol-amine, triethanolamine, N, N-dimethylethanolamine or diisopropylamine, serve mainly to increase the pH value of the liquid for recording. These are normally present in a proportion of 0 to 10% by weight, preferably 0.5 to 5% by weight in the liquid for recording.
