The present invention relates to a new 2,9-dechlorination in a plate form, the method of its production and to its use for coloring high molecular weight organic material.

In the US 4370270 described phthalocyanine copper in the β-modification in plate form, which is synthesized in the form of flakes of a length of not less than 10 μm, and a width of 3 μm. When nail hot drying this pigment blue metallic reflex of the finished coating.

Chinagreen, also called 7,14-dioxo-5,7,12,14-tetrahydroquinoline(2,3-b)acridine are valuable pigments. Many patents describe the special transparent or opaque forms hinkreonsok pigment having a particle size of less than 1 μm. In addition, it is known that linear 2,9-dechlorination the following formula

exists in three polymorphic modifications (Chemical Reviews, 67, 1, 1-18 (1967)). The greatest industrial interest is bluish-red γ-modification.

It is well known that stable organic pigments can be sublime at high temperatures. By heating powdered 2,9-dechlorination to temperatures above 350°C were grown crystals of increased size plastination structure with a thickness of 2-3 microns and a length of 50 to 150 μm, and conducted scientific discussion of their education(Farbe und Lack, 77, 8, 759-769 (1971).

In EP 0466649 shown that the crude 2,9-dechlorination for which it is known that it exists in the form of particles acicular prismatic shape, with sizes ranging from 0.1 to 5 μm, can easily and efficiently be turned into a "reflex" pigment having plastination morphology, by recrystallization from a polar solvent in the presence of long chain thiol and grounds. Indicated that the obtained lamellar form exhibits excellent reflex effects when different coating systems.

The method described in EP 0466649, carried out by stirring the crude 2,9-dechlorination in a polar solvent such as N,N,N', N'-tetramethylrhodamine, N,N-dimethylacetamide, N-methylformamide and preferably N,N-dimethylformamide, together with long-chain aliphatic a thiol, such as n-decandiol, n-dodecanthiol and tert-dodecanethiol, and the substrate and heating the mixture to temperatures above 50°C, preferably to the boiling temperature until complete conversion, typically within 1 to 24 h depending from the selected conditions. During the transformation into a plate shape may contain water in amounts not impeding the transformation. Records of the pigment obtained in accordance with EP 0466649 have a length of 1 to 45 μm, a width of 0.1-20 μm, and a thickness equal to 0.05-5 MK is. Particularly preferred pigment contains at least 50 wt.% records a length of 1-20 mm, a width of 0.1 to 7 μm, and a thickness of 0.5 to 2.0 μm.

According to the invention it has been unexpectedly found that the crude 2,9-dechlorination for which it is known that it exists in the form of particles acicular prismatic shape, with sizes ranging from 0.01 to 5 μm, can easily and efficiently be turned into a "reflex" pigment having plastination morphology, without the use of long chain aliphatic thiol.

Thus, the present invention relates to a method for 2,9-dechlorination according to claim 1 of the claims in the plate and pigmentary open form, which includes

(a) dispersion and partial dissolution of the crude 2,9-dechlorination in polar solvent selected from N,N,N',N'-tetramethylrhodamine, N,N-dimethylacetamide, N-methylformamide, N,N-dimethylformamide and N-methylpyrrolidone in the presence of a base at temperatures from 100°C to the boiling point of the solvent,

(b) deposition of 2.9-dechlorination necessary in plate form by adding water to reduce the temperature.

A new method of obtaining a plate shape 2,9-dechlorination carried out by dispersion and partial dissolution of the crude 2,9-dechlorination in the Arctic is rastvoritele, selected from N,N,N',N'-tetramethylrhodamine, N,N-dimethylacetamide, N-methylformamide, N,N-dimethylformamide and N-methylpyrrolidone in the presence of a base at temperatures from 100°C to the boiling point of the solvent, preferably from 120°C to the boiling point of the solvent. At this stage of the method may be present a small amount of water. Deposition of 2.9-dechlorination necessary in plate form is carried out by adding water to reduce the temperature, and the rate of addition of water and temperature control are the most important parameters. The transformation can be carried out under pressure, while turning at atmospheric pressure is preferred. You can get 2,9-dechlorination in more angular plate shape compared to the one described in EP 0466649 by very careful control of recrystallization, which is provided by the addition of water and lower temperature. After precipitation, the suspension is cooled to room temperature, filtered, the filtrate washed with water to remove sodium methylate and the pigment is dried.

The source of the crude 2,9-dechlorination is a conventional commercially available needle (needle-prismatic) crude 2,9-dechlorination having a particle size of from 0.01 to 5 μm.

Suitable polar and solvents are N,N,N',N'-tetramethylrhodamine, N,N-dimethylacetamide, N-methylformamide and N,N-dimethylformamide (DMF) and N-organic (NMP). N,N-Dimethylformamide and N-organic are preferred, and N-organic is the most preferred. The solvent may contain water. The addition of a small amount of water at the stage a) was preferred.

Suitable bases are hydroxides or methoxide alkali metals. The grounds, which proved to be particularly suitable for this purpose are the hydroxides of lithium, sodium, potassium and/or their methoxide, preferably sodium methoxide.

The molar ratio of the amount of the crude 2,9-dechlorination to the amount of water is from 1:2 to 1:20. If the amount of water is insufficient, then the output records 2,9-dechlorination is bad and formation of undesirable forms of pigment (needles).

The amount of solvent depends on the polarity of the solvent and the amount used of the base, i.e. the solubility of 2,9-dechlorination in an alkaline solvent.

If the solvent is NMP, NMP contained in an amount of 3 to 30 moschata, preferably from 4 to 20 moschata, to 1 part of pigment, and a base, such as, for example, sodium methoxide, is contained in an amount of 0.01 to 1.0 moschata, preferably from 0.1 to 0.8 moschata, 1 part of p is gment.

A new method of obtaining a plate shape 2,9-dechlorination is illustrated in more detail using NMP as a solvent, but is not limited to them.

Base, preferably sodium methylate, mixed with NMP at room temperature. It turned out that before the addition of untreated needle 2,9-dechlorination to a mixture of NMP and sodium methylate useful to add a small amount of water. The mixture is then heated to a temperature of from about 170°C to the boiling point of NMP and stirred for 0.25 to 8 hours at the same temperature. Within 1 to 3 hours, slowly add the water and the temperature of the mixture decreases. At about 130°C. precipitates the desired lamellar form of 2,9-dechlorination. After precipitation, the suspension is cooled to room temperature, filtered, the filtrate washed with water to remove sodium methylate and the pigment is dried.

Deposition of 2.9-dechlorination necessary in plate form is carried out by adding water to reduce the temperature, and the rate of addition of water and temperature control are the most important parameters. Usually a sufficient temperature reduction provided by the addition of water, but not necessarily can reduce the heat.

The molar ratio of the amount of the crude 2,9-dechlorination is the amount of water is from 1:2 to 1:20. If the amount of water is insufficient, then the output records 2,9-dechlorination is bad and formation of undesirable forms of pigment (needles).

The amount of pigment, the base and the solvent are associated with the temperature used in stage a), and therefore with a degree of dissolution of the crude 2,9-dechlorination in a mixture of base and solvent. NMP is usually contained in the amount of 3 to 30 moschata, preferably from 4 to 20 moschata, to 1 part of pigment, and the base is usually contained in a quantity of 0.01 to 1.0 moschata, preferably from 0.1 to 0.8 moschata, to 1 part of pigment.

2,9-Dechlorination in plate form, obtained in accordance with the present invention, has a length of from 1 to 45 μm, a width equal to from 0.1 to 20 μm, and an average thickness equal to from 0.01 to 5 μm, preferably from 0.03 to <2 μm, particularly preferably from 0.03 to 0,200 μm. 2,9-Dechlorination contains no6-C18-thiol.

Particularly preferred pigment contains at least 50 wt.% plates with length equal to from 1 to 20 μm, a width equal to from 0.1 to 7 μm, and a width of from 0.05 to <0,200 mm.

When having a thickness of 0.4 mm of rolled sheets of PVC (polyvinyl chloride), as shown in the application example 1, 2,9-dechlorination in plate form, get in compliance and with the present invention (1.0% pigment), characterized in that

- the value of the hue h to weaken is ≤31,

- the value of the hue h is a bandwidth equal to ≥351,0, and

the lightness L* for bandwidth equal to ≥20, the color is measured using a Minolta CM3610d relatively Leneta B&W. In the preferred embodiment, the intensity of color* for bandwidth equal to ≥50.

In addition, the value b* for 2,9-dechlorination proposed in the present invention, is reduced, and the value of a* for 2,9-dechlorination proposed in the present invention, is the same or increases when the angle of illumination and viewing angle (the angle of specular reflection) from 45°/110° (+25°) to 45°/90° (+45°). In a preferred embodiment of the present invention, the value b* for 2,9-dechlorination proposed in the present invention, is reduced, and the value of a* for 2,9-dechlorination proposed in the present invention, increases when the angle of illumination and viewing angle (the angle of specular reflection) from 45°/110° (+25°) to 45°/90° (+45°) to 45°/60° (+75°). Measurement according to the angle spend using the card Datacolor FX 10 and Black Leneta. If the value b* for 2,9-dechlorination of example 1 in EP 0466649 also decreases when the angle of illumination and viewing angle (the angle of specular reflection) from 45°/110° (+25°) to 45°/90° (+45°), then e is a value and* decreases when the angle of illumination and viewing angle (the angle of specular reflection) from 45°/110° (+25°) to 45°/90° (+45°). This difference leads to the perception that 2,9-dechlorination proposed in the present invention, has a more deep/wide color change.

2,9-Dechlorination in plate form, obtained in accordance with the present invention, differs from those described in EP 0466649 the fact that it has a lower covering power (greater transparency) and has (more significant) sparkling. In addition, it has clear corner plate form that provides new color effects, change colors depending on the angle and characteristic x-rays. Cm. figure 1-3.

High-molecular organic material, for pigmentation which can be applied pigments or composition of pigments, proposed in the present invention may be of natural or synthetic origin. High-molecular organic materials typically have a molecular weight of approximately from 103up to 108g/mol or more. They can represent, for example, natural resins, drying oils, rubber or casein, or derived from natural substances, such as chlorinated rubber, modified oil alkyd resins, viscose, simple or complex esters of cellulose, such as ethylcellulose, cellulose acetate, cellulose propionate, acetobutyrate cellulose or nitrocellulose, but preferably fully synthetic organic polymers (thermoreg the sector of plastics and thermoplastics), such as obtained by polymerization, polycondensation or polyprionidae. From the class obtained by the polymerization of resins in particular can be mentioned polyolefins such as polyethylene, polypropylene and polyisobutylene, and substituted polyolefins, such as polymerization products of vinyl chloride, vinyl acetate, styrene, Acrylonitrile, esters of acrylic acid, esters of methacrylic acid and butadiene, as well as the products of copolymerization of these monomers, preferably such as ABS resin plant copolymer) or EVA (copolymer of ethylene and vinyl acetate).

From the group of resins obtained by polyprionidae, and resins obtained by the polycondensation can be mentioned, for example, condensation products of formaldehyde with phenols, the so-called phenolic plastics, and condensation products of formaldehyde with urea, thiourea or melamine, the so-called aminos, and polyester resins, used as resins for surface coatings, saturated, such as alkyd resins, or unsaturated, such as maleate resin; and linear polyesters and polyamides, polyurethanes and silicones.

These high-molecular compounds may be contained individually or in mixtures, in the form of plastics or melts. They can also be in the form of their monomers or in Ameritania state in dissolved form, as film formers or binders for coatings or printing inks, such as, for example, boiled linseed oil, nitrocellulose, alkyd resins, melamine resins, urea-formaldehyde resins or acrylic resins.
