As the coloring matter, the composition contains an aqueous suspension of the pigment or dye solutions. As the acrylate binder composition contains a copolymer of methyl acrylate, butyl acrylate and methacrylic acid in a weight ratio of 62: 35:3, respectively, or other acrylate binder, for example, on the basis of illimitability, ethyl acrylate, methyl methacrylate. As the stabilizer composition contains ethoxylated monoalkylphenols based trimers of propylene or carboxymethylate. As the aliphatic alcohol composition contains butandiol or tetraethylene glycol.The proposed composition was prepared as follows. In a container equipped with a stirrer, download successively water, an aqueous solution of the dye emiliania (n=400 rpm) for 3 hours. Then the composition is filtered and Packed in bottles.It should be noted that the pigments used in the form of 5-10% of the energy of water suspensions have the size of the water-insoluble particles of 1.0 to 1.5 μm, PH 8-9, the content of mechanical impurities not more than 0.2%; resistance to water and light - 5-6 points. Water suspensions of pigments are produced in the following colors: red, blue, black, green, brown, yellow. They are all suitable for use in the proposed composition provided that the above characteristics.As a red pigment in the composition is azopigments scarlet; as pigment yellow color in the composition include azopigments yellow (Hansa).For more songs of blue color includes blue phtalocyanine pigment, and green - green phtalocyanine pigment. Green phtalocyanine pigment unlike blue contains in the molecule 15 chlorine atoms replace hydrogen atoms on the outer faces of the crystals, which gives the surface some hydrophilic.As the black pigment in the composition is a suspension of carbon black in the composition of the brown color is water suspension pagmamahal to be used acid dyes and direct in the form of a 5-10% aqueous solutions.As antifreeze composition comprises a mixture of urea [(NH2)2CO], 1,2-propylene glycol [C3H6(OH)2] and glycerol [C3H5(OH)3] at a weight ratio of 1.8:2,0:2,5 respectively. This ratio helps to ensure uninterrupted operation of the registering device in the temperature range from +35 to -35oC. in Addition, the antifreeze prevents drying of the composition on the output device.As the acrylate binder used copolymers of methyl acrylate, butyl acrylate, and methacrylic acid in a weight ratio of 62:35:3, respectively. Can be used and other acrylate binder, for example, on the basis of illimitability, ethyl acrylate, methyl methacrylate.All acrylates sufficiently stable to light aging. To increase the frost resistance of acrylate binder add ammonia water. Mass fraction of dry substances, % - 53; surface tension, mn/m - 50; PH 8,0; viscosity, 25.In the stabilizer is used surfactants such as AF-10, ethoxylated monoalkylphenols-based propylene trimer following formula: RC6H4O(C2H4O)nN,
where R is a branched alkyl rediculasly carboxymethylate polyoxyethylene isononylphenol based trimers of propylene, General formula: RO(C2H4O)nCOONa,
where R is isononylphenol;
n is the number of moles of ethylene oxide.When using these nonionic surfactants as stabilizer ensures the stability of the composition during the operation of the device due to power and structural transformations of water due to the hydration of polar groups.As the aliphatic alcohol composition contains butandiol, for example, 2-butyn-1,4-diol of General formula (HOCH2-CC-CH2OH) with a boiling point 238oC. Butandiol prevents drying of the composition in the device, provides elasticity image, uninterrupted flow of the composition to paper media, including after the break.Examples of compositions of the claimed composition are presented in table 1, and their properties are shown in table 2. As follows from table 2, using the claimed composition for recording devices can quickly form an image and at a temperature of +35oWith, and at a temperature of -35oWith; he easily comes to paper basis, including after a break in work (1 h, 24 h, 72 h), with the first touch of the diagram paper forms a clear continuous lines, which are svetasto the mi, not exposed to radiation). In addition, these compounds have a high resolution, you can create drawings with a line width of 0.2-0.3 mm (examples 2-11). The compositions in examples 2-11 superior to the known speed of image formation and at a temperature of +35 and the -35oSecond, whereas the application of known composition is impractical due to poor runoff at high speeds. Moreover, unlike known, they, due to the high speed receipt paper media, form a contrast image after the break, form a continuous line of length 10 times higher than in example 1, have light fastness, while the known composition loses the intensity of the image upon irradiation ("pale") compared to lines made before irradiation; resolution of well-known composition is lower than in examples 2-11, almost twice.Compositions containing components with exorbitant values (examples 12-17) compared to the proposed (2-11), inferior to the latter by a number of indicators. Thus, the increase in the content of the coloring matter (example 12) and the reduction of its content (example 13) leads to a decrease in the duration of formation of the image is stoikosti.When you reduce the amount of binder in the composition (example 14) increases the time of image formation at a temperature of +35 and -35oWith the creation of a continuous image is inferior to the examples 2-11, deteriorating the resolution. With increasing binder (example 15) after a break in operation 24 h, 72 h, the composition is not immediately comes to paper media, but only after several switching on and switching off of the device. When the decrease in the composition of aliphatic alcohol (example 16) deteriorates the image formation and its quality after the break operation, continuous line, it is possible to spend up to 2500 m, and then get broken lines.With the increasing content of aliphatic alcohol (example 17) because it is too lightweight runoff composition deteriorates the resolution and, consequently, increases the width of the lines.Thus, the composition made in accordance with the invention, thanks to the selection and combination included in its composition of ingredients solves the problem quickly form a continuous image on a chart paper in the temperature range from +35 to -35oWith and ensure uninterrupted flow of costi composition allows to expand the color gamut of consumables for modern multi-channel recording devices.The proposed composition suitable for use in domestic appliances quick action, as well as foreign, in particular, the company "Yuma" (Germany). Due to the foregoing, the use of the proposed structure is economically and technically feasible. 1.
