１３００ｍＬのビーカーに、ラウリルメタクリレート ５６ｇ、エチレングリコールジメタクリレート １９ｇ及びラウロイルパーオキシド １．５ｇを加え、溶液を得た。また、平均粒径０．２５μｍの酸化チタン（ＣＲ−５０、石原産業社製）、平均粒径０．３８μｍのベンガラ（ベンガラ七宝、森下ベンガラ社製）、平均粒径０．０７×０．７μｍ（針状のため）の黄酸化鉄（イエローＬＬＸＬＯ、チタン工業社製）を、表１に示す割合で混合し、メチルハイドロジェンポリシロキサンを用いて撥水処理（無機粉体に対して２％）した。次に、得られた溶液と、撥水処理した無機顔料とを、表１に示す内包率になるよう混合し、分散させて、分散液を得た。この分散液に１質量％ポリビニルアルコール（ゴーセノールＧＨ−１７、日本合成化学工業社製）水溶液７５０ｇを添加し、超音波分散機を用いて分散した（時間と強度で粒径がコントロールできる）。得られた分散液を１０００ｍＬのセパラブルフラスコに加え、その後、該セパラブルフラスコ内の気相を窒素置換した。次いで、前記分散液を１５０r/minで撹拌しながら、７５℃で８時間、窒素雰囲気下に維持して、重合を行なった。重合終了後、得られた産物を濾過して固体を回収し、水で洗浄し、次いで、減圧乾燥して、表１に示す平均粒径の無機顔料含有ポリマー粉体１２０ｇを得た。
得られたポリマー粉体について、透過率及びヘイズ値を測定した。結果を表１に併せて示す。
Production Example 1 (Production of polymer powder)
To a 1300 mL beaker, 56 g of lauryl methacrylate, 19 g of ethylene glycol dimethacrylate and 1.5 g of lauroyl peroxide were added to obtain a solution. In addition, titanium oxide with an average particle size of 0.25 μm (CR-50, manufactured by Ishihara Sangyo Co., Ltd.), Bengala with an average particle size of 0.38 μm (Bengara Cloisonne, manufactured by Morishita Bengala), average particle size of 0.07 × 0.7 μm Yellow iron oxide (for needle shape) (Yellow LLXLO, manufactured by Titanium Industry Co., Ltd.) was mixed in the ratio shown in Table 1, and water repellent treatment using methylhydrogenpolysiloxane (2% with respect to inorganic powder) )did. Next, the obtained solution and the water-repellent-treated inorganic pigment were mixed and dispersed so as to have the inclusion rate shown in Table 1 to obtain a dispersion. To this dispersion was added 750 g of a 1% by weight polyvinyl alcohol (GOHSENOL GH-17, manufactured by Nippon Synthetic Chemical Industry) aqueous solution and dispersed using an ultrasonic disperser (the particle size can be controlled by time and strength). The obtained dispersion was added to a 1000 mL separable flask, and then the gas phase in the separable flask was purged with nitrogen. Next, while stirring the dispersion at 150 r / min, polymerization was carried out at 75 ° C. for 8 hours under a nitrogen atmosphere. After the polymerization was completed, the obtained product was filtered to collect a solid, washed with water, and then dried under reduced pressure to obtain 120 g of an inorganic pigment-containing polymer powder having an average particle size shown in Table 1.
About the obtained polymer powder, the transmittance | permeability and the haze value were measured. The results are also shown in Table 1.
（測定方法）
各粉体の全透過率及びヘイズ値は、Ｈａｚｅ−ｍｅｔｅｒ ＨＭ−１５０（村上色彩技術研究所社製）を用いて測定した。測定には、波長５５０ｎｍをピークとした光を用いた。
試料の調製は以下のように行った。粉体を０．４ｇ秤取り、これをアミノ変性シリコーン（ＳＦ８４１７、東レ・ダウコーニング社）１．６ｇに練り込み、ガラス板へ塗布する。練り込みはフーバーマーラー（混錬機：YOSHIMITSU社製、フーバーマーラー）を用いて１００回転で行い、１回かきとりを入れた後、更に１００回転で練り込んだ。またガラス板への塗布は、０．０２５mmのコーター（YOSHIMITSU社製、コーター）を用いて行った。
(Measuring method)
The total transmittance and haze value of each powder were measured using Haze-meter HM-150 (Murakami Color Research Laboratory Co., Ltd.). For the measurement, light having a peak at a wavelength of 550 nm was used.
The sample was prepared as follows. 0.4 g of the powder is weighed and kneaded into 1.6 g of amino-modified silicone (SF8417, Toray Dow Corning) and applied to a glass plate. The kneading was performed at 100 revolutions using a Hoover Marler (kneader: YOSHIMITSU, Hoover Marler), after scraping once, and further kneading at 100 revolutions. The glass plate was coated using a 0.025 mm coater (manufactured by YOSHIMITSU, coater).
なお、ヘイズ値（Ｈ）は拡散透過率（Ｔｄ）を全透過率（Ｔｔ）で割った値に１００を掛けることで算出されるが、本発明（実施例）に記載するヘイズ値（Ｈ）は各サンプルの厚さによる測定誤差をなくすため、各サンプルが厚さ１５μｍのときの値に換算した値（Ｈ15）である。換算式は以下のとおりである。サンプルの厚さは、透過率、ヘイズ値測定後、膜厚計（YOSHIMITSU社製）を用いて測定する。 The haze value (H) is calculated by multiplying the value obtained by dividing the diffuse transmittance (Td) by the total transmittance (Tt) by 100, and the haze value (H) described in the present invention (Example). Is a value (H15) converted to a value when each sample has a thickness of 15 μm in order to eliminate measurement errors due to the thickness of each sample. The conversion formula is as follows. The thickness of the sample is measured using a film thickness meter (manufactured by YOSHIMITSU) after measuring the transmittance and haze value.
式中、Ttは全透過率、Tdは拡散透過率、Ｌは膜厚である。膜厚は測定後の塗布膜を膜厚計で測定した値を用いる。 In the formula, Tt is the total transmittance, Td is the diffuse transmittance, and L is the film thickness. For the film thickness, a value obtained by measuring the coating film after measurement with a film thickness meter is used.

Water repellent treatment (2% with respect to the inorganic powder) was performed using methyl hydrogen polysiloxane. Next, 20 parts by mass of the obtained dispersion and 80 parts by mass of viscose were roughly mixed to obtain an inorganic pigment mixed viscose. Thereafter, the mixture was mixed with an aqueous solution of polyacrylic acid soda that is an anionic polymer, heated to 80 ° C. over 10 minutes, and further mixed at 80 ° C. for 30 minutes to obtain solidified particles. Next, the coagulated particles are filtered off with a glass filter, neutralized with 0.5% by mass hydrochloric acid, further washed with excess water and methanol, dried under reduced pressure, and colored spherical cellulose powder containing an inorganic pigment. Got. As a result of analyzing the obtained particles using a scanning electron microscope, the shape was substantially spherical, and the average particle size was 10 μm.

実施例１〜１７と同様にして、ファンデーションを製造した。
得られたファンデーションは、塗布過程においては筋むらができにくく、すばやく密着し、塗布直後の見た目の仕上がりは、均一であり、マットな質感で、厚ぼったく見えないものである。また、５時間経過しても、マットな質感が維持され、５時間経過後でも毛穴が目立ちにくいものであった。

Foundations were produced in the same manner as in Examples 1-17.
The resulting foundation is less likely to cause streaks in the application process, quickly adheres, and has an even, visually matt finish and does not look thick. Further, even after 5 hours, the matte texture was maintained, and pores were hardly noticeable even after 5 hours.
