Conventionally, generally available black pearlescent pigments exhibiting a gray to blackish-gray color have either an iron oxide layer containing triiron tetroxide attached to the surface of pearlescent pigment particles with a weak force, or a combination of iron oxide and pearls. These are mixtures of lustrous pigments, and these pigments have severe color separation, and when applied on a desk or dispersed in water, the iron oxide and pearlescent pigments are completely separated. This phenomenon occurs.

For example, when such a black pearlescent pigment is used in cosmetics, color separation between the iron oxide and the pearlescent pigment easily occurs, and the iron oxide adheres to the surface of the desk, causing the coating film of the cosmetic to deteriorate. It looks grainy and the pearlescent pigments appear floating, causing a decline in quality as a cosmetic. Furthermore, when such a black pearlescent pigment is mixed with other colored pearlescent pigments, the colors easily separate during the normal mixing and crushing process, and the external color and the applied color do not match. This also caused the problem.

Some attempts have been made to solve the problems of black pearlescent pigments as described above. For example, in JP-A No. 49-128027, an oxidizing agent is contained in an aqueous dispersion of titanium dioxide-coated mica, and an aqueous solution of a base and an iron (n) salt is added to produce black pearls. A method for obtaining luster pigments has already been disclosed. However, in this method, the reaction process leading to iron (II) salt → iron hydroxide → triiron tetroxide proceeds too rapidly due to the presence of an excess oxidizing agent, and Since the particles have a larger particle size than other iron oxides, such as ferric oxide (Fe203) particles, there are problems such as difficulty in obtaining a uniform and strong coating. had.

Therefore, the present inventor conducted intensive research to solve the problems faced by the conventional colored pearlescent pigments and their manufacturing method, and found that iron hydroxide was first deposited on the surface of titanium dioxide-coated mica particles. After increasing the binding strength between the coloring agent and the pearlescent pigment, the pigment is deposited in the form of triiron tetroxide, and finally, the reaction process is carried out to convert the iron hydroxide into triiron tetroxide using the action of an oxidizing agent. As a result, a black pearlescent pigment is obtained in which the particle surface of titanium dioxide-coated mica particles is effectively and firmly coated with triiron tetroxide. It was discovered that an unprecedented red pearlescent pigment could be obtained by converting iron trioxide to 1 il of ferric oxide, leading to the completion of the present invention.

At this time, the amount of dispersed mica coated with titanium dioxide is 40 weight -
It is preferable to select the following range, preferably 1 to 20% by weight, particularly preferably 2 to 10% by weight. If the amount exceeds 40% by weight, the dispersion system becomes slurry-like and uniform quality cannot be obtained, and on the other hand, if the amount of dispersion is too small, industrial advantages will be lost. Further, the heating temperature is preferably in the range of 50 to 100°C in view of the reaction rate. Furthermore, if air is present in the dispersion, the generated triiron tetroxide will be oxidized to ferric oxide, and it will be difficult to control the reaction system, so it is recommended to blow nitrogen gas in advance to drive out oxygen. good.

After pH adjustment, at the same time as a base, iron (Ji) salts such as ferrous chloride, ferrous sulfate, and ferrous phosphate, nitrates such as potassium nitrate, sodium nitrate, ammonium nitrate, and chlorates such as potassium chlorate are added. , sodium chlorate,
An aqueous solution in which an oxidizing agent having a relatively mild action such as ammonium chlorate is dissolved is gradually dropped into the dispersion. At this time, since iron (II) salt is unstable in an aqueous system,
It is preferable to add an acid such as sulfuric acid, hydrochloric acid, or nitric acid to the additive solution to acidify the pll and stabilize the iron salt. During the coating formation, the pH was kept constant between 7 and 12 by continuing to drop a base.

Thereafter, the reaction is continued to be stirred, and the reaction is terminated when the desired degree of coloring is reached.Then, the pigment is washed with water and passed through the mouth according to a conventional method. In this case, it is preferable to wash with water until there are no traces of additives such as ammonia or sulfuric acid contained in the raw or proboscis, or of produced impurities. When the obtained mouthwash is dried under reduced pressure at 130° C. or lower, a black colored pearlescent pigment is obtained.

Here, the color (degree of coloring) of the black colored pearlescent pigment is determined by changing the amount of iron (II) salt and oxidizing agent added.
It can be controlled arbitrarily by doing this. For example, when the coating amount of triiron tetroxide is 5M relative to the weight of titanium dioxide-coated mica, the color still appears silver, but as the coating amount increases, the blackness becomes stronger, and when it exceeds 20% by weight, it becomes almost black. exhibits.

However, when the total amount exceeds 25% by weight, the luster begins to disappear and the pearlescent pigment approaches a simple black pigment. Therefore, when it is desired to use it as a black pearlescent pigment in cosmetics, for example, it is practical to use one with a coating amount in the range of 20 to 25% by weight.

Next, 5% of the obtained black colored pearlescent pigment was added to the atmosphere.
When heat-treated in the temperature range of 00 to 1000°C, triiron tetroxide is converted to ferric oxide and becomes a red colored pearlescent pigment.The color (degree of coloration) of this red colored pearlescent pigment Naturally, there is a correlation with the amount of triiron tetroxide covered in the original black colored pearlescent pigment, and the color changes from pale brick color (reddish brown) to deep red.

That is, the black pearlescent pigment according to the present invention obtained in Production Example 5 (silver gray) and Production Example 7 (black gray), Merck & Co. #, Kororona/Zotina Schiltsk (silver gray) and Mallinckrodt Co. Using a commercially available black pearlescent pigment, Spectra Pearl BKW (black gray), each sample was first ground in a grinder at 6,000 rpm, and then the ground product was suspended in water and ground in a disper. The mixture was dispersed and then centrifuged at 3,000 rpm to see if the layers would separate. As a result, two commercial products were successfully separated, but nine products prepared by the method of the present invention were not separated.
