Description

  The present invention relates to a pearly luster pigment and a method for producing the same, and a cosmetic, a coating composition, a resin composition and an ink composition using the same.

  Conventionally, pearly luster pigments include fish phosphorus foil, powder simple pigments such as basic lead carbonate and bismuth oxychloride, and mica particles coated with titanium dioxide or iron oxide (hereinafter referred to as “pearl mica”). There are known composite pigments. Further, a pearlescent pigment obtained by coating C glass with iron oxide or rutile titanium dioxide is known (see Patent Document 1).

International Publication WO97 / 46624 Pamphlet

  Of these pearly luster pigments, powdery simple pigments are natural products, so that they are difficult to obtain stably and have problems such as poor chemical resistance. In addition, since pearl mica has cleavage properties, the surface not covered with titanium dioxide or iron oxide is easily exposed when blended with paints or resins, and sufficiently enhances the glitter of coating films and resin products. I couldn't.

  Furthermore, the C glass used in WO97 / 46624 contains boric acid and zinc oxide, so it is difficult to obtain due to its special composition and is expensive.

  The present invention is intended to solve such problems. Its purpose is pearly luster that gives glitter to cosmetics, paint products, resin products, and ink products over a long period of time, even when blended in cosmetics, paints, resins, and inks. It is to provide a pigment. Furthermore, the present invention provides an efficient method for producing this pearly luster pigment, and cosmetics and paint compositions, resin compositions, and ink compositions that exhibit a high-grade appearance by containing this pearly luster pigment. There is to do.

In order to achieve the above object, the invention according to claim 1 is a pearly luster pigment in which the surface of a scaly glass substrate is coated with iron oxide and / or titanium dioxide.
The scale-like glass base material has an average thickness of 0.1 to 20 μm, an average particle diameter of 5 to 2000 μm, and its composition is an A glass composition or an E glass composition.

  A glass and E glass are easily available because they do not contain boric acid or zinc oxide, or can be low in content.

  Invention of Claim 2 is a manufacturing method of the pearl luster pigment of Claim 1, Comprising: It makes it the summary to precipitate iron oxide and / or titanium dioxide in the solution on the surface of the scale-like glass. To do.

  The gist of the invention described in claim 3 is the method for producing a pearly luster pigment according to claim 2, wherein the iron oxide raw material is iron chloride, iron sulfate, iron phosphate or iron nitrate.

  According to a fourth aspect of the present invention, in the method for producing a pearly luster pigment according to the second aspect, the titanium dioxide is a rutile type, and the raw material is titanium tetrachloride, titanium trichloride or titania sulfate. The gist.

  The gist of the invention according to claim 5 is a cosmetic containing the pearly luster pigment according to claim 1.

  The gist of the invention described in claim 6 is the coating composition containing the pearly luster pigment according to claim 1.

  The gist of the invention described in claim 7 is the resin composition containing the pearly luster pigment according to claim 1.

  The gist of the invention described in claim 8 is the ink composition containing the pearly luster pigment according to claim 1.

  The pearly luster pigment of the present invention is a glass whose base material is smooth and has no open walls, and is coated with iron oxide and / or titanium dioxide, and exhibits a very brilliant color tone, Smoothness is good. Furthermore, if this pearly luster pigment is used as a filler for cosmetics, paints, resin moldings, and inks, it is possible to provide a product with a glittering feeling.

  Hereinafter, embodiments of the present invention will be described in detail. However, the present invention is not limited to the following embodiments as long as the gist of the present invention is not exceeded.

  The base material of the pearly luster pigment of the present invention is flaky glass, and examples of the base material include flaky glass produced by a melting method. The flaky glass can be produced by a known technique, for example, a method described in JP-B Nos. 41-17148 and 45-3541. That is, molten glass is extruded from a circular slit, and air or the like is injected into the glass to expand it into a hollow cylinder to form a thin and uniform glass film, which is then pulverized. Further, as described in US Pat. No. 5,017,207, a method of spraying molten glass onto a rotating disk and quenching and forming it into a flake shape, or described in British Publication No. 989,671. In this method, the molten glass is blown out into a fiber shape from a slit that rotates, and is applied to a wall surface to be rapidly cooled and formed into a flake shape.

  Since the flaky glass is manufactured by melting an inexpensive raw material, the cost can be kept low. Moreover, since the molten glass having a free surface is cooled and solidified, the surface is very smooth. Furthermore, since it is amorphous and does not have cleavage properties, no step is generated on its surface.

  This pearly luster pigment is made of scale-like glass having an average base material thickness of 0.1 to 20 μm and an average particle diameter of 5 to 2000 μm. Since the scaly glass has a smooth surface and is transparent, the glittering feeling due to the coating of iron oxide or rutile titanium dioxide is further enhanced. If the average particle size is less than 5 μm, sufficient glitter cannot be given. If the average particle size exceeds 2000 μm, it breaks during processing, which is not practical.

  On the other hand, if the thickness of the scaly glass exceeds 20 μm, the cosmetic, coating film, resin molded product and printed surface containing the glass are covered with protrusions, and a rough feeling is produced, so that the commercial value is impaired.

  In addition, since the product containing it becomes easy to produce light scattering and the external appearance becomes a silky tone so that the particle size of scale-like glass is small, it is necessary to select the particle size product suitable for a use application.

  The composition of the glass flakes is usually composed of silicon dioxide as a main component and a metal oxide such as aluminum oxide, calcium oxide or sodium oxide.

  From the application, C glass mainly used in the corrosion resistant field, E glass used in the electrical field, A glass used for window glass, high strength glass showing high strength, and the like can be mentioned. Table 1 shows the composition of these glasses.

  The raw material for the glass flakes is not particularly limited. However, since C glass contains boric acid and zinc oxide, it is difficult to obtain due to its special composition and is expensive.

  The thickness of the iron oxide is not particularly limited as long as the target color tone can be obtained. Similarly, the film thickness of titanium dioxide is not particularly limited as long as the target color tone can be obtained. However, the crystal structure of titanium dioxide is preferably a rutile type with little photocatalytic property.

[Iron oxide coating]
The method for coating iron oxide is as follows.
After scaly glass is immersed in purified water and heated to 50 to 80 ° C., hydrochloric acid is added to adjust the pH to 2 to 4. Here, an iron oxide raw material and an alkaline solution that neutralizes with the raw material are added while maintaining the pH to precipitate iron oxide and / or a hydrate thereof on the glass flake surface. Examples of the iron oxide raw material include iron chloride, iron sulfate, iron phosphate, and iron nitrate. Moreover, as an alkaline solution which neutralizes with the said raw material, potassium hydroxide, sodium hydroxide, ammonia water, etc. are mentioned, The 1 type (s) or 2 or more types chosen from these can be used.

[Rutyl type titanium dioxide coating]
On the other hand, the process of coating the scaly glass surface with rutile titanium dioxide is as follows.

(1) Pretreatment process The glass flakes are immersed in an aqueous solution of stannous chloride, and the surface thereof is sensitized. The sensitization treatment is performed in advance as described above in order to easily attach platinum particles or palladium particles to the surface of the glass flakes in the next step. The scaly glass that has undergone this treatment is recovered, and excess stannous chloride remaining on the surface is removed by washing with water.

  Subsequently, this scaly glass is immersed in a chloroplatinic acid or palladium dichloride aqueous solution, and an activation treatment for precipitating platinum or palladium on its surface is performed.

(2) Rutile-type titanium dioxide coating step The scaly glass subjected to the above treatment is immersed in purified water and heated to 50 to 80 ° C., and then adjusted to pH 1.3 or less by adding hydrochloric acid. A titanium dioxide raw material and an alkaline solution that neutralizes with the raw material are added to the titanium glass and / or hydrate thereof on the surface of the glass flakes while maintaining the pH. Examples of the raw material for titanium dioxide include titania salts such as titanium tetrachloride, titanium trichloride, and titania sulfate. Moreover, as an alkaline solution which neutralizes with the said raw material, potassium hydroxide, sodium hydroxide, ammonia water, etc. are mentioned, The 1 type (s) or 2 or more types chosen from these can be used. By appropriately adjusting the pH of the solution and the solution temperature, rutile titanium dioxide can be directly deposited. The relationship between the pH and the solution temperature is specifically described in Japanese Patent Laid-Open No. 2001-31421 proposed by the present inventor. If rutile-type titanium dioxide can be deposited directly from a solution, it is not necessary to first precipitate anatase-type titanium dioxide and then heat it to cause a crystal transition to the rutile-type as in the prior art, thereby improving production efficiency. . However, in the case where titanium dioxide is coated on a glass flake coated with iron oxide, pretreatment is not always necessary.

  By blending this pearly luster pigment into cosmetics, it is possible to produce cosmetics with a color that has an unprecedented luster and a good feel. 1-100 mass% is suitable for the content rate of the pearly luster pigment in cosmetics. If it is less than 1% by mass, color development is weak. In the case of powdery cosmetics such as eye shadows and face colors used as loose powder, it may be 100% because it is mixed with human fats present on the skin at the time of use.

  This pearly luster pigment may be appropriately hydrophobized according to the purpose of the cosmetic. Hydrophobic treatment includes methylhydrogenpolysiloxane, high viscosity silicone oil or silicone compound such as silicone resin, treatment with anionic or cationic surfactant, nylon, polymethylmethacrylate, polyethylene , Treatment with a polymer compound such as fluororesin or polyamino acid, or treatment with a perfluoro group-containing compound, lecithin, collagen, metal soap, lipophilic wax, polyhydric alcohol partial ester or complete ester, or a combined treatment thereof Is mentioned. However, any method can be used as long as it is generally applicable to the hydrophobizing treatment of the powder, and is not limited to these methods.

  In addition to the above-mentioned pearly luster material, other components usually used in cosmetics can be appropriately blended with this cosmetic as necessary. Examples of other components include inorganic powder, organic powder, pigment, dye, oil component, organic solvent, resin, or plasticizer. For example, inorganic powders include talc, kaolin, sericite, muscovite, phlogopite, saucite, biotite, lithia mica, vermiculite, magnesium carbonate, calcium carbonate, diatomaceous earth, magnesium silicate, calcium silicate, silicic acid.

  As dyes, red 201, red 202, red 204, red 205, red 220, red 226, red 228, red 405, orange 203, orange 204, yellow 205, yellow 401 And organic pigments such as No. 404 and Blue No. 404, Red No. 3, Red No. 104, Red No. 106, Red No. 227, Red No. 230, Red No. 401, Red No. 505, Orange No. 205, Yellow No. 4, Yellow No. 5, Organic pigments such as yellow 202, yellow 203, green 3 and blue 1 zirconium, barium or aluminum lake, or natural pigments such as chlorophyll or β-carotene.

  Furthermore, as oily components, squalane, liquid paraffin, petrolatum, microcrystalline wax, okezolite, ceresin, myristic acid, palmitic acid, stearic acid, oleic acid, isostearic acid, cetyl alcohol, hexadecyl alcohol, oleyl alcohol, 2-ethylhexane Cetyl acid, 2-ethylhexyl palmitate, 2-octyldodecyl myristate, neopentyl glycol di-2-ethylhexanoate, glycerol tri-2-ethylhexanoate, -2-octyldodecyl oleate, isopropyl myristate, triisostearin Acid glycerol, tricoconut oil fatty acid glycerol, olive oil, avocado oil, beeswax, myristyl myristate, various hydrocarbons such as mink oil or lanolin, silicone oil, higher fatty acid, fat Esters, higher alcohols, or waxes, and the like.

  Also, organic solvents such as acetone, toluene, butyl acetate or acetate, resins such as alkyd resin or urea resin, plasticizers such as camphor and acetyltributyl citrate, UV absorbers, antioxidants, preservatives, surfactants , Moisturizers, fragrances, water, alcohols, or thickeners.

  Examples of the cosmetics include various forms such as powder, cake, pencil, stick, ointment, liquid, emulsion or cream. These include, for example, makeup cosmetics such as foundation, lipstick, eye shadow, blusher, eyeliner, nail enamel or mascara, hair cosmetics such as hair color, facial cosmetics such as lotion, emulsion or cream. It is.

  As the coating composition, there are generally a liquid coating composition and a powder coating composition. This pearly luster pigment can be contained in any composition.

  The vehicle component used in the liquid paint is preferably a cross-linking curable resin composition containing a base resin and a cross-linking agent as main components. Examples of the base resin include acrylic resins having a crosslinkable functional group, polyester resins, alkyd resins, and fluorine resins. Examples of the crosslinking agent include methylolated and / or alkyletherified melamine resins or urea resins, and polyisocyanate compounds (including blocked products). Further, a self-curing resin or a thermoplastic resin may be present in the liquid paint. The solvent is preferably an organic solvent for paint and / or water.

  The blending amount of the pearly luster pigment in the coating composition is preferably 0.1 to 30 parts by mass per 100 parts by mass (solid content) of the vehicle component. A more preferable blending amount is 0.5 to 10 parts by mass. When this compounding quantity is less than 0.1 mass part, a coating film cannot exhibit sufficient glitter. On the other hand, when the amount is more than 30 parts by mass, the glittering feeling is not improved for an increase in the blending amount.

  In addition to the components described above, the coating composition may include other colored pigments, metallic pigments (for example, aluminum pigments and iron oxide pigments), and interference color pigments (for example, glass flakes coated with metal oxides, mica, etc.) 1 type or 2 types or more selected from.

  Examples of the form of the coating composition include an organic solution type, a high solid type, a non-aqueous dispersion type, an aqueous solution type, and a water dispersion type. Moreover, it can adjust to each said form by a known method.

  The method for applying the coating composition to an object to be coated (for example, metal or plastic) is not particularly limited, and may be a known method such as spraying, roller coating, brush coating, or dipping method. Further, the coating composition may be directly applied to the surface of the object to be coated, but surface treatment such as primer coating or intermediate coating may be performed in advance as necessary. The thickness of the coating film is not particularly limited, and may be appropriately adjusted depending on the application.

  In the case of a resin composition, the resin as a base material is not particularly limited as long as it is a moldable thermoplastic resin. For example, polyethylene, polypropylene, ethylene-propylene copolymer, polymethylpentene, polystyrene, ABS, AS, AES, acrylic resin, methacrylic resin, polyamide, polyethylene terephthalate, polybutylene terephthalate, polyimide, polyarylate, polyacetal, polycarbonate, polyphenylene ether, Polysulfone, polyphenylene sulfide, polyethersulfone or polybutadiene, or a copolymer, mixture or modified product of these polymers may be mentioned. In particular, acrylic resin, methacrylic resin, polystyrene, AS resin, or polycarbonate is preferable as a base material of the resin composition of the present invention because of its high transparency.

  When the content of the pearly luster pigment is too small in the resin composition, the glitter feeling due to the pearly luster pigment becomes inconspicuous. On the other hand, if the amount is too large, the physical properties of the resin composition may be adversely affected. Considering these, it is preferable to add the white pigment in a ratio of 0.05 to 10 parts by mass with respect to 100 parts by mass of the base material of the resin composition.

  Furthermore, within the range not impairing the purpose of the resin composition of the present invention, coloring pigments, other metallic pigments (for example, aluminum pigments, iron oxides or silver-coated glass flakes) and interference color pigments (for example, metal oxide-coated mica) Etc.), stabilizers or flame retardants may be added as appropriate.

  A resin composition can be manufactured by mixing each said structural material using a tumbler, a Nauta mixer, a blender, or an extruder, for example. Then, by molding this resin composition into a specific shape using an injection molding machine or the like, a glossy and deep resin molded product is formed.

Hereinafter, the present invention will be described more specifically with reference to examples. Note that the present invention is not limited to the following examples.
For the pearly luster pigments prepared in each Example and Comparative Example, the glitter was evaluated by the following method.
