Description
【０００１】
【発明の属する技術分野】
本発明は、筆記具、印刷インキ、塗料関連分野、化粧品関連分野などに好適に使用することができる光輝性固形描画材において、特にワックス類を含有するクレヨン、パス等の光輝性固形描画材に関する。
【０００２】
【従来の技術】
従来、ワックス類を含有するクレヨン、パス等の固形描画材では、強い光輝感と立体感の筆跡乃至塗膜を持つ光輝性固形描画材が提供されていなかった。
【０００３】
【発明が解決しようとする課題】
本発明の目的は、従来の固形描画材と比較して、より強い光輝感を持ち、さらには従来の固形描画材にはなかった強い立体感を併せ持つ筆跡乃至塗膜を得ることができる光揮性固形描画材、中でもワックス類を含有するクレヨン、パス等の光輝性固形描画材を提供するところにある。
【０００４】
【課題を解決するための手段】
上記目的を達成するため鋭意検討した結果、本発明は、必須成分として、ガラスフレーク顔料、体質顔料、ワックス及びオイルを含んでなる光輝性固形描画材を採用した。また、本発明は、必須成分として、金属被覆無機顔料、体質顔料、ワックス及びオイルを含んでなる光輝性固形描画材を採用した。なお、本発明でいう「金属被覆無機顔料」とは、金属及び金属酸化物のうち少なくともいずれか１つの物質が被覆された無機顔料を総称するものとして定義される。
【０００５】
従って、上記のガラスフレーク顔料を含有したクレヨン、パス等の光輝性固形描画材は、従来の固形描画材と比較して、より強い光輝感と立体感を有する筆跡乃至塗膜を得ることができる。
【０００６】
また、上記の金属被覆無機顔料を含有したクレヨン、パス等の光輝性固形描画材も、無機顔料が金属蒸着等で着色されているため、従来の固形描画材と比較して、より強い光輝感と立体感を有する筆跡乃至塗膜を得ることができる。
【０００７】
【発明の実施の形態】
（ガラスフレーク顔料）
本発明で用いられるガラスフレーク顔料は、フレーク状ガラスが金属などで被覆された構造からなり、光輝感と立体感を有する顔料として定義される。一例を挙げれば、フレーク状ガラスが無電解メッキ法により金属で被覆されたガラスフレーク顔料を使用することができる。例えば、銀で被覆された東洋アルミニウム社製の商品名「メタシャインＲＥＦＳＸ−２０１５ＰＳ」、「メタシャインＲＥＦＳＸ−２０２５ＰＳ」、及び「メタシャインＲＥＦＳＸ−２０４０ＰＳ」、日本板硝子社製の商品名「メタシャインＲＣＦＳＸ−５４８０ＰＳ」、「メタシャインＲＣＦＳＸ−５２３０ＰＳ」「メタシャインＲＣＦＳＸ−５１５０ＰＳ」、「メタシャインＲＣＦＳＸ−５０９０ＰＳ」を例示することができる。
【０００８】
また、フレ−ク状ガラスがスパッタリング法により金属で被覆されたガラスフレーク顔料も使用することができる。例えば、銀で被覆された東洋アルミニウム社製の商品名「クリスタルカラ−ＧＦ２１２５」、「クリスタルカラーＧＦ２１２５−Ｍ」、「クリスタルカラーＧＦ２１４０」、「クリスタルカラーＧＦ２１４０−Ｍ」がある。また、ニッケル・クロム・モリブデンで被覆された同社製の商品名「クリスタルカラーＧＦ２５２５」、「クリスタルカラーＧＦ２５２５−Ｍ」、「クリスタルカラーＧＦ２５４０」、「クリスタルカラーＧＦ２５４０−Ｍ」がある。また、真鍮で被覆された同社製の商品名「クリスタルカラーＧＦ２５０」、銀合金で被覆された同社製の商品名「クリスタルカラーＧＦ１３４５」、チタンで被覆された同社製の商品名「クリスタルカラーＧＦ１４４５」がある。
【０００９】
本発明ではガラスフレーク顔料のメジアン径は５００μｍ以下、特に５〜１００μｍが好適である。ガラスフレーク顔料のメジアン径が５００μｍを超えると筆記時滑りが発生し均一な筆跡乃至塗膜ができない状態になるため好ましくない。メジアン径が５μｍ未満の場合は、上記の粒子が小さすぎるため光輝性が低下する。
【００１０】
本発明におけるガラスフレーク顔料は、固形描画材全量に対して１〜５０重量％含まれていることが好ましい。ガラスフレーク顔料が固形描画材物全量に対して１重量％未満の場合は光輝性及び立体感が充分でない。また、ガラスフレーク顔料が固形描画材全量に対して５０重量％を超えると、固形分が多くなり、固形描画材としては粘度が上がりすぎ、流動性が低下し、成形しにくい状態になり好ましくない。ガラスフレーク顔料の最適配合量は３〜２０重量％である。
【００１１】
なお、ガラスフレーク顔料は１種又は２種以上を混合して用いることができる。また、ガラスフレーク顔料を、金属被覆無機顔料、アルミニウム顔料、パ−ル顔料などの光輝性顔料と混合して用いることもできる。
【００１２】
（金属被覆無機顔料）
本発明で用いる金属被覆無機顔料とは、例えば金属蒸着等で金属及び又は金属酸化物が被覆された無機顔料として構成されている。一例を挙げれば、酸化鉄(III)が被覆されたアルミニウムを用いることができる。例えばＢＡＳＦ株式会社製の商品名「Paliocrom Gold L2000」、「Paliocrom Gold L2002」、「Paliocrom Gold L2020」、「Paliocrom Gold L2022」、「Paliocrom Gold L2025」「Paliocrom Orange L2800」がある。また、酸化鉄(III)が被覆された雲母を用いることができる。例えばＢＡＳＦ株式会社製の商品名「Paliocrom Red Gold L2500」、「Paliocrom Red L4000」がある。また、アルミニウム−マンガン被覆の雲母状酸化鉄(III) を用いることができる。例えばＢＡＳＦ株式会社製の商品名「Paliocrom Copper L3000」及び「Paliocrom Copper L3001」がある。また、還元二酸化チタンが被覆された雲母を用いることができる。例えばＢＡＳＦ株式会社製の商品名「Paliocrom Blue Silver L6000」、「Paliocrom Blue Silver L6001」がある。また、二酸化チタンが被覆された雲母も用いることができる。
【００１３】
上記の金属被覆無機顔料のメジアン径も、ガラスフレーク顔料のメジアン径と同様に、５００μｍ以下、特に５〜１００μｍが好適である。金属被覆無機顔料のメジアン径が５μｍ未満の場合は、上記の無機顔料粒子が小さすぎるため光輝性に劣り、また５００μｍを超えると筆記時滑りが発生し均一な塗膜ができない状態になるため好ましくない。
【００１４】
金属被覆無機顔料の配合量も、ガラスフレーク顔料と同様に、固形描画材全量に対して１〜５０重量％含まれていることが好ましい。上記の無機顔料が固形描画材全量に対して１重量％未満の場合は光輝性が充分でない。また、上記の無機顔料が固形描画材全量に対して５０重量％を超えると、固形分多くなり、固形描画材としては粘度が上がりすぎ、流動性が低下し、成形しにくい状態になり好ましくない。上記の無機顔料の最適配合量は３〜２０重量％である。
【００１５】
なお、金属被覆無機顔料は１種又は２種以上を混合して用いることができる。また、金属被覆無機顔料を、ガラスフレーク顔料、アルミニウム顔料、パ−ル顔料などの光輝性顔料と混合して用いることもできる。
【００１６】
（体質顔料）
体質顔料としては、固形描画材に含まれるものとして、公知の体質顔料を用いることができる。体質顔料としては、透明なもの、特にバインダー中で透明なものを好適に用いることができる。また、潤滑性（滑り）が優れているものが好ましい。具体的には、体質顔料としては、例えば、炭酸マグネシウム、炭酸カルシウム、硫酸バリウム、タルク、クレー、カオリン、シリカ、アルミナシリケート、ベントナイト等を例示することができる。そしてこれらの中から適宜選択して単独で又は組み合わせて使用できる。これらの中でも、炭酸マグネシウム、炭酸カルシウム、タルクが最適である。
【００１７】
体質顔料の配合量は、固形描画材全量に対して５〜６０重量％、好ましくは１５〜５０重量％である。体質顔料の配合量が固形描画材全量に対して５重量％より少ないと滑りが低下して潤滑性が低下するとともに、着き（定着性）が低下する。一方、体質顔料の配合量が固形描画材全量に対して６０重量％より多いと着色性、成型性が低下する。
【００１８】
（ワックス）

There is.
[0009]
In the present invention, the median diameter of the glass flake pigment is preferably 500 μm or less, particularly 5 to 100 μm. When the median diameter of the glass flake pigment exceeds 500 μm, slipping occurs during writing, and a uniform handwriting or coating film cannot be formed. When the median diameter is less than 5 μm, the above-mentioned particles are too small, resulting in a decrease in glitter.
[0010]
It is preferable that the glass flake pigment in this invention is contained 1 to 50weight% with respect to the solid drawing material whole quantity. When the glass flake pigment is less than 1% by weight with respect to the total amount of the solid drawing material, the glitter and stereoscopic effect are not sufficient. Further, if the glass flake pigment exceeds 50% by weight with respect to the total amount of the solid drawing material, the solid content increases, the viscosity of the solid drawing material increases too much, the fluidity is lowered, and it becomes difficult to form, which is not preferable. . The optimum amount of glass flake pigment is 3 to 20% by weight.
[0011]
In addition, a glass flake pigment can be used 1 type or in mixture of 2 or more types. Further, the glass flake pigment can be used by mixing with a bright pigment such as a metal-coated inorganic pigment, an aluminum pigment, or a par pigment.
[0012]
(Metal-coated inorganic pigment)
The metal-coated inorganic pigment used in the present invention is configured as an inorganic pigment coated with a metal and / or metal oxide by, for example, metal deposition. As an example, aluminum coated with iron (III) oxide can be used. For example, trade names “Paliocrom Gold L2000”, “Paliocrom Gold L2002”, “Paliocrom Gold L2020”, “Paliocrom Gold L2022”, “Paliocrom Gold L2025”, and “Paliocrom Orange L2800” manufactured by BASF Corporation are available. In addition, mica coated with iron (III) oxide can be used. For example, there are trade names “Paliocrom Red Gold L2500” and “Paliocrom Red L4000” manufactured by BASF Corporation. Alternatively, aluminum-manganese-coated mica-like iron oxide (III) can be used. For example, there are trade names “Paliocrom Copper L3000” and “Paliocrom Copper L3001” manufactured by BASF Corporation. Further, mica coated with reduced titanium dioxide can be used. For example, there are trade names “Paliocrom Blue Silver L6000” and “Paliocrom Blue Silver L6001” manufactured by BASF Corporation. Also, mica coated with titanium dioxide can be used.
[0013]
The median diameter of the metal-coated inorganic pigment is also preferably 500 μm or less, particularly 5 to 100 μm, like the median diameter of the glass flake pigment. When the median diameter of the metal-coated inorganic pigment is less than 5 μm, the above-mentioned inorganic pigment particles are too small, resulting in inferior luster, and when it exceeds 500 μm, slippage occurs during writing and a uniform coating cannot be obtained. Absent.
[0014]
The blending amount of the metal-coated inorganic pigment is preferably 1 to 50% by weight with respect to the total amount of the solid drawing material, similarly to the glass flake pigment. When the inorganic pigment is less than 1% by weight based on the total amount of the solid drawing material, the glitter is not sufficient. Further, if the above-mentioned inorganic pigment exceeds 50% by weight based on the total amount of the solid drawing material, the solid content is increased, the viscosity of the solid drawing material is excessively increased, fluidity is lowered, and it becomes difficult to mold, which is not preferable. . The optimum blending amount of the above inorganic pigment is 3 to 20% by weight.
[0015]
The metal-coated inorganic pigment can be used alone or in combination of two or more. In addition, the metal-coated inorganic pigment can be used by mixing with a bright pigment such as a glass flake pigment, an aluminum pigment, or a par pigment.
[0016]
(External pigment)
As the extender pigment, a known extender pigment can be used as one included in the solid drawing material. As the extender pigment, a transparent pigment, particularly a pigment that is transparent in the binder, can be suitably used. Moreover, what is excellent in lubricity (sliding) is preferable. Specific examples of extender pigments include magnesium carbonate, calcium carbonate, barium sulfate, talc, clay, kaolin, silica, alumina silicate, bentonite and the like. And it can select suitably from these and can be used individually or in combination. Of these, magnesium carbonate, calcium carbonate, and talc are optimal.
[0017]
The amount of the extender is 5 to 60% by weight, preferably 15 to 50% by weight, based on the total amount of the solid drawing material. If the amount of the extender pigment is less than 5% by weight based on the total amount of the solid drawing material, the slippage is lowered, the lubricity is lowered, and the adhesion (fixing property) is lowered. On the other hand, if the amount of the extender pigment is more than 60% by weight based on the total amount of the solid drawing material, the colorability and moldability deteriorate.
[0018]
(wax)
In the present invention, wax can be used. The wax is preferably a wax that melts when heated and is solid at room temperature. Examples of the wax include wood wax, beeswax, carnauba wax, beef tallow oil, polyethylene wax, α-olefin oligomer, lard, paraffin wax and the like. As the wax, paraffin wax, beef tallow oil, and carnauba wax are suitable.
[0019]
The blending amount of the wax is 20 to 80% by weight, preferably 30 to 50% by weight, based on the total amount of the solid drawing material. When the blending amount of the wax is less than 20% by weight based on the total amount of the solid drawing material, the strength of the solid drawing material is lowered, the moldability is lowered, and the adhesion (fixing property) is lowered. On the other hand, when the blending amount of the wax is more than 80% by weight with respect to the total amount of the solid drawing material, the color becomes transparent and light.
[0020]
(oil)
In the present invention, oil can be used. The oil is preferably a transparent oil that dissolves in wax. Examples of the oil include liquid paraffin, spindle oil, coconut oil, castor oil and the like. As the oil, liquid paraffin is suitable.
[0021]
The blending amount of the oil is 3 to 20% by weight, preferably 5 to 15% by weight, based on the total amount of the solid drawing material. When the blending amount of the oil is less than 3% by weight with respect to the total amount of the solid drawing material, slippage is reduced, drawing property is lowered, and adhesion (fixing property) is lowered. On the other hand, when the blending amount of the oil is more than 20% by weight based on the total amount of the solid drawing material, the strength is weakened and the heat resistance is lowered.
[0022]
(Coloring agent)
In the present invention, a colorant can be used. By using the colorant, the color of the solid drawing material can be adjusted to various colors. It is important to use a colorant that does not react with the glass flake pigment or the metal-coated inorganic pigment and does not affect the color development of the glass flake pigment or the metal-coated inorganic pigment. In the present invention, a bright solid drawing material containing no colorant is also included.
[0023]
Specifically, as the colorant, water-soluble dyes such as acid dyes, direct dyes, basic dyes (triphenylmethane, xanthene, anthraquinone, metal complex, copper phthalocyanine, etc.), phthalocyanine, quinacridone, Organic pigments or inorganic pigments such as carbon black and titanium oxide, fluorescent pigments, colored resin emulsions, and the like can be used. A coloring agent can be used 1 type or in mixture of 2 or more types.
[0024]
In the present invention, as described above, the colorant may be contained or not contained. However, when a colorant is contained, it is preferably contained in an amount of 40% by weight or less, particularly 20% by weight or less, based on the total amount of the solid drawing material. When the colorant exceeds 40% by weight with respect to the total amount of the solid drawing material, the glitter feeling is lowered and the slip is lowered. Furthermore, the moldability also decreases.
[0025]
In the solid drawing material (such as crayon) of the present invention, known additives can be appropriately blended as necessary as other components.
[0026]
In the method for producing a solid drawing material of the present invention, basically, the above components may be mixed uniformly. For example, when blending a colorant, first, a wax and a colorant (pigment, etc.) are mixed using a kneader (roll mill, kneader, etc.). Then, a volatile solid drawing material composition can be prepared by heating and melting and adding and mixing the glass flake pigment and / or metal-coated inorganic pigment and extender pigment. The solid drawing material composition having a specific shape can be obtained by pouring the solid drawing material composition into a mold having a desired shape and cooling and solidifying the composition. In the above method, when each component is dissolved and mixed, it may be heated as necessary. The solid drawing material such as crayon and pass of the present invention can be produced by using these components according to a known production method of crayon and pass.
[0027]
Since the solid drawing material of the present invention uses a specific glitter pigment, it can exhibit excellent writing properties and higher glitter. In particular, the writability can be applied to all materials such as paper, metal, ceramic, plastic and glass.
[0028]
In addition, it has excellent adhesion, and the handwriting or coating film after adhesion does not transfer color or drop off the glitter pigment. Further, it is superior in handling than conventional crayons and passes.
[0029]
The glittering solid drawing material of the present invention is used in the writing instrument field, printing-related field, paint-related field, cosmetics-related field, and the like, and is useful in various applications such as for writing instruments, for drawing, for applicators. Further, the present invention can be widely applied to glittering solid drawing materials containing glass flake pigments and / or metal-coated inorganic pigments other than wax, crayons containing oils, passes and the like.
