BACKGROUND OF THE INVENTION The present invention relates to a pigment preparation based on beta modification of copper phthalocyanine, substituted phthalocyanine of copper and alkylolamide of aliphatic acids. The preparation is suitable for pigmentation of intaglio inks. In the production of intaglio inks intended for three- and four-color printing, pigment preparations based on copper naphthalocyanine beta modification are used. The average particle size of the copper phthalocyanine in these preparations must be about 0.55 m, so that the pigmenting ability of the pigment is not utilized. Such small particles have a great tendency to form aggregates (secondary particles), thereby reducing the high free surface energy values. Therefore, copper phthalocyanine particles are treated with vigorous adjuvants to prevent re-aggregation and to improve the dispersibility of the product of the respective application environment (British Pat. No. 900,757, 978,242, 1,100,103, U.S. Pat. 245 600, etc.).

A disadvantage of possible rotogravure pigment preparations is that the dispersion of these preparations in the solvent-binder + auxiliary system has a high apparent viscosity. This leads to difficulties both in the production of printing inks and in rotary noise printing. The aim is to produce low-viscosity printing inks, as the pigment content can be increased in color as well as the printing speed.

Research has now found that the pigment preparation of the present invention removes these drawbacks. This pigment preparation contains 69.0 to 94.5% wt. copper phthalocyanine beta diffusion, 5.0 to 25.0 wt%, of a compound or mixture of compounds of formula I R 1 -CONHmbCH 2) p HJ "(O where R 1 is a saturated or unsaturated, linear or branched aliphatic radical of the number of carbon atoms 12 to 20, m is 0 or 1,

The micronization of copper phthalocyanine can be carried out in the presence of a compound of formula II * which, in this process, is the surface of copper phthalocyanine particles, micronized in the presence of a compound or a mixture of compounds of formula I and II, and the compounds of formula II can be produced by copper chlorosulfonataphthalocyanine. and partial sulfonation of copper phthalocyanine) and subsequent condensation of the chlorosulfonated derivative with monoalkylolamine or dialkylolamine. An important advantage of the technology for the production of compounds of formula II is that there is no release of hazardous substances in the manufacturing process. The compounds hitherto used for the preparation of the botulinum preparations (MS, vol. 245,660) were produced by chloromethylation of copper phthalocyanine by treatment with formaldehyde and hydrogen chloride, with carcerogenic dichlorodimethyl ether being formed by side reactions. By using a pigment preparation containing copper beta-phthalocyanine according to the invention and the compounds of the formula I and II, intaglio inks having better flow properties can be produced than the colors produced using known compositions not containing phthalocyanine derivatives. Example 1 A suspension containing 0.4 kg of a beta-modification phthalocyanine medium (copper phthalocyanine content 98% by weight), 0.048 kg of di- (2-ethylhexyl) sulfo-sodium succinate and 0.016 kg of FCM (SO3H) 2 (SO2NHCH2CH2OH) 2 was ground in a 0.6-liter pearl horizontal mill, filled with 0.48 L 0.7 mm glass beads. The suspension was ground through two passages at a circumferential speed of 15 rs discs and at a flow rate of 1 *. Then the dispersion was diluted with 5 liters of water and an emulsion containing 0.040 kg of palladium monoethanolamide, 0.020 kg of monoethanol oleic acid, 0.006 kg of di- (2-ethylhexyl) sulphonate succinate was added gradually and under stirring to the dispersion so dispersed. 1.6 liters of water · The mixture was heated to 80 ° C and stirred for 60 minutes · The product was filtered off, washed, dried at 90 ° C and ground. · The pigment preparation was used for the production of intaglio ink with which proofs were made. , that the proofs are high-quality, predetermined dispersing hardness and are comparable to that produced using ink with pigmented known preparation. The apparent viscosity of the xylene dispersion (30.0 wt% concentration) at a shear rate of 10 s -1 and a temperature of 25 ° C was 1.07 Pas, the comparative dispersion had a viscosity of 6.0 Pas. Example 2 A pigment preparation was prepared as described in Example 1, comprising 82 wt% copper phthalocyanine beta modification, 16 wt% stearic acid monoethanol amide and 2 wt% FCM (SO 3 H) 1> 5 (SO 2 N (CH 2 CH 2 OH)). 2) 1i8 Intaglio printing ink made using this product had a lower apparent viscosity than that prepared using standard preparation, test proofs were satisfactory.
