The invention relates to aqueous inks and coatings containing modified carbon product.

There are different classifications of ink used in the present time. The categories include: printing ink, dried by ultraviolet irradiation ink, ink for ballpoint pens, ink pad stamps (seals) or masking ink. Basically, the ink may consist of four major categories of materials. These include edge is, for example, toners and colorants, provide color contrast with respect to the substrate. Ligament or varnishes act as carriers during the operation of the application. In the process of drying ligament binds the dye to the substrate. Additives affect the covering ability of the ink film properties, the drying speed and the properties after application. And, finally, the solvents, in addition to participating in the formation of the clutch, are used to reduce the viscosity of the ink and the speed of drying and tar. Typically, the ingredients of these four classes are weighed, mixed, crushed (i.e., dispersed), together or separately in accordance with a given recipe.

Currently, the predominant black pigments are carbon black, such as furnace carbon black, which are used as dyes or in dry, powdered form and in the form of filled pasta, or as a liquid concentrate. Forms filled paste and liquid concentrate are more economical because they require little effort to dispersion. Usually the shape of the dye affects the tone, stability, volume, covering power, gloss, rheological properties, application after application and the print quality.

th printing, screen printing, screen printing, Photocopying printing and electrostatic printing. Thus, ink can be found in such consumer use of as Newspapers, publications, trade, cardboard boxes, books, corrugated boxes, paper bags, toilet paper, textiles, etc., In McGraw-Hill's Encyclopedia of Science and Technology, Vol. 7, pgs. 156-164 provides additional details print existing inks and their use, which is entirely included in this description by reference.

Despite the presence of ink in the trade, there is still need to get ink, easier to prepare.

Coatings are used to impart a decorative, protective and functional properties of many kinds of surfaces. Such surfaces include: wrapping materials, metals, appliances, fittings, rigid cardboard, lumber and plywood, marine vessels, repair equipment, cars, cans and soft cardboard. Some coatings, such as coatings subsea pipelines are used for defensive purposes. Others, such as exterior automotive coatings perform as decorative and protective purposes. Other, in addition, provide New ship bottoms, other protect banks for food and drinks. Flint chips, printed circuits, coating fiber waveguides for transmitting signals and the magnetic coating on the tape for recording and computers are among the many so-called high technology application of coatings.

Every year produced tens of thousands of types of coatings. They are based mainly on one or more binders, such as resins or polymers, and at least one solvent, one or more pigment and, optionally, on some supplements. Many coatings are produced and applied in liquid form and turn in "hard" film after application to the substrate.

Pigments and coatings provide opacity and color. The composition of the pigment determines the gloss of the film in the ready state and can have a significant impact on its mechanical properties. Some pigments even slow down corrosion. In addition, the pigments have an impact on the viscosity and increase the covering properties of the coating. An important factor in determining the properties of the pigment is the size of its particles and the distribution of particle sizes. Processes for the production of pigments are designed to get the pigment. In the manufacture of pigments preferably dispersing the pigment to obtain a stable dispersion, where most, if not all of the pigment particles, divided into separate groups of particles, introduced in accordance with the development of the product manufacturers pigment. Dispersing pigment comprises wetting, separation and stabilization.

There are three categories of sheaves: those in which the binder is soluble in water, those in which it is dispersed in a colloidal solution, and those in which it emuleret with the formation of the latex. The compositions of the coatings for surfaces usually are more or less viscous liquid with three main components: a substance or combination of substances forming the film and called a binder, a pigment or combination of pigments and volatile liquid. The combination of binder and volatile liquid is called a bundle, which can be a solution or dispersion of fine particles of the binder in herstorical. Pigments are finely dispersed, insoluble solid particles dispersible in conjunction coverage and distributed throughout the bundle in the finished film. As the pigment dispersant is used, the surface of the ence and Engineering, pgs. 160-171 (1990), which is included in this description by reference.

Modified carbon products do not necessarily require grinding process conventional type and does not necessarily need to use in inks and coatings dispersing agents. In essence, the modified carbon products require only nizkodohodnogo stirring or mixing to easily dispersing the pigment in water.

Carbon products can be obtained through the interaction of carbon, as described above, with the salt of the page in the liquid reaction medium for coupling at least one organic group to the surface of the carbon. The preferred reaction medium comprises water, any environment that contains water, and any environment that contains alcohol. Water is the preferred medium. These modified carbon products in which carbon is a carbon soot, and various methods for their preparation are described in application for U.S. patent N 08/356660, entitled "Interaction of carbon black with diazonium compounds, the resulting products with carbon black and their use", filed December 15, 1994, and in its partially continuing application, which are incorporated in this description by reference. Modified carbon patent serial number 08/356653, entitled "Interaction of carbon materials with diazonium compounds and the resultant carbon products" dated December 15, 1994, and is also included here as a reference.

To obtain the above-mentioned modified carbon products, you only need to salt the page was stable enough could be reaction with carbon. So that the reaction could occur with some diazonium compounds, it should be borne in mind that, on the other hand, they may be unstable and subject to decomposition. Some of the processes of decomposition can compete with the interaction between carbon and salt, page and reduce the total number of organic groups associated with carbon. In addition, the reaction may occur at elevated temperatures at which many diazonium salts can be sensitive to decomposition. Elevated temperatures can also favorable to increase the solubility of the diazonium salts in the reaction medium and to improve its manufacturability during the process. However, elevated temperatures may result in some loss of diazonium salts due to other processes of decomposition.

Carbon black may vzaimodeistvovat in the form of granules of carbon black with the proper amount of water. If desired, the pellets of carbon black can be obtained using the conventional methods of granulation. The other carbon species can interact with the salt of the page in the same way. In addition, when receiving the aqueous inks and coatings are modified carbon products based on carbon other than carbon, preferably carbon was ground to fine particle size before the reaction with the salt of the page, to avoid unwanted precipitation in the ink. Organic group that can be provided to the carbon, represent groups, substituted ionic or capable to ionize the group as a functional group. Able to ionize the group represents a group which can form an ionic group in your environment. The ionic group may be anionic or cationic group, and is able to ionize the group can form an anion or a cation. Capable of ionization of functional groups forming anions include, for example, acid groups or salts of acid groups. Organic group, therefore, include groups derived from organic acids. Preferably, (a) an aromatic group or a C1-C12substituted or unsubstituted alkyl group and b) at least one acid group having the pH pKa < 11 or at least one salt of an acidic group having a pKa < 11, or a mixture of at least one acidic group having a pKa < 11, and at least one salt of an acidic group having a pKa < 11. Index pKa of the acid group refers to the pKa value of the organic group as a whole and not only to acid Deputy.

More preferably pKa < 10, more preferably pKa < 9. Preferably, the aromatic group or an alkyl group of the organic group was directly linked with carbon. The aromatic group may be additionally substituted or unsubstituted, for example, alkyl groups. C1-C12is an alkyl group can be branched or unbranched and preferably is ethyl. More preferably the organic group is a phenyl or naftalina group and the acid group is a group of sulfonic acid group Sultanovich acid group, phosphonic acids or group of carboxylic acids.

Preferred substituted sulfophenyl group is hydroxysultaine group or a salt thereof.

Special organic groups can ionize functional group forming an anion, are p-sulfophenyl, 4-hydroxy-3-sulfophenyl and 2-solitarily.

Amines are examples able to ionize functional groups, which form a cationic group and can join the same organic groups as described above for able to ionize groups, which form anions. For example, amines can be protonated for the formation of ammonia Gretel pKb of less than 5. Quaternary ammonium groups (-NR3+and Quaternary hostnine group (-PR3+) also represent examples of cationic groups and can join the same organic groups as described above for able to ionize groups, which form anions. Preferably, the organic group contains an aromatic group as a phenyl or naftalina group and a Quaternary ammonium or Quaternary fosfoniya group.

The advantage of the modified carbon group, is that the modified carbon products may have increased dispergirovannogo in the water compared to the untreated carbon. Basically dispersibility in water modified carbohydrate foods increases with the number of organic groups linked to the carbon which is able to ionize the group, or more able to ionize groups attached to the organic group. Thus, the increase in the number able to ionize groups associated with modified carbon products, should improve their dispersibility in water and allows you to adjust dispergirovannom in water to the desired level. It should be noted that the dispersibility in water of modified carbon products containing amine as the organic group attached to the carbon can be increased by podkashlivanija water ligaments.

Because the dispersibility in water of modified carbon products depends to some extent on the stabilization of the charge, it is preferable that the ionic strength of the aqueous medium was less than 0.1 molar. More preferably, the ionic strength was less than 0.01 molar. Predpochtitelen or salts.
