【発明の詳細な説明】
〔発明の目的〕
（産業上の利用分野）
本発明は、熱可塑性樹脂成形物にキメ細かく優雅な光沢
を与える樹脂組成物に係り、特に成形性あるいは成形物
の物性等を損なわずに成形物表面に上記特性を奏し得る
成形材料樹脂組成物に関する。[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a resin composition that imparts a fine-grained and elegant luster to a thermoplastic resin molded article, and particularly relates to a resin composition that imparts a fine-grained and elegant luster to a thermoplastic resin molded article, and particularly to a resin composition that imparts a fine-grained and elegant luster to a thermoplastic resin molded article, and particularly improves moldability, physical properties of the molded article, etc. The present invention relates to a molding material resin composition that can exhibit the above characteristics on the surface of a molded product without impairing the properties.

ことにより上記表面特性を付与することが行われている
。(Prior Art) Conventionally, so-called pearl pigments, which are mica powder coated with titanium dioxide, have been used to give gloss to the surfaces of paints and resin moldings, giving them a luxurious feel. Especially injection molding,
BACKGROUND ART When molding containers for cosmetics or detergents by blow molding or the like, the above-mentioned surface characteristics are imparted by using a molding material containing a pearl pigment in a resin.
一方、成形物表面の光沢調整方法として、粒子径の大き
な（数１０ミクロン以上）炭酸カルシウムやタルク等の
無機充填剤を樹脂中に配合し、成形品表面に艶消効果あ
るいは防眩効果を付与する試みもある。On the other hand, as a method for adjusting the gloss on the surface of molded products, inorganic fillers such as calcium carbonate and talc with large particle diameters (several tens of microns or more) are blended into the resin to impart a matte or anti-glare effect to the surface of the molded product. There are also attempts to do so.
しかし樹脂成形品の表面に光沢を付与する目的でパール
顔料を使用すると、人工的で硬質な光沢となり、キメ細
か（優雅な、例えばシルクの様な光沢を現出することが
できなかった。また艶消を目的として粗大な粒子径を有
する炭酸カルシウム等を樹脂中に配合する方法では微妙
な光沢の調整が非常に困難である。However, when pearl pigments are used to add luster to the surface of resin molded products, the result is an artificial, hard luster, making it impossible to create a fine-grained (elegant, silk-like luster). In the method of blending calcium carbonate or the like having a coarse particle size into the resin for the purpose of matting, it is very difficult to finely adjust the gloss.
（発明が解決しようとする課題）
そこで本発明者は前述の欠点を改良すべく鋭意研究を行
った結果、比較的粒径の大きい光拡散性を有する無機化
合物とパール顔料とを併用して樹脂中に配合することに
より、成形品表面にキメ細かく優雅な光沢を付与し得る
ことを見出した。(Problems to be Solved by the Invention) Therefore, as a result of intensive research to improve the above-mentioned shortcomings, the present inventor has developed a resin using a combination of an inorganic compound having a relatively large particle size and a light-diffusing property and a pearl pigment. It has been found that by blending it into the molded product, it is possible to impart a fine-grained and elegant luster to the surface of the molded product.
本発明の目的は成形性あるいは成形物の物性等を損わず
に成形物表面にキメ細かく優雅な光沢を付与することが
できる樹脂組成物を提供することにある。An object of the present invention is to provide a resin composition capable of imparting a finely textured and elegant gloss to the surface of a molded article without impairing its moldability or the physical properties of the molded article.
（課題を解決するための手段）
本発明は、熱可塑性樹脂に平均粒径１〜１０μｍの光拡
散性無機化合物０．１〜１０重量％およびパール顔料０
．１〜５重量％を配合してなる樹脂組成物である。(Means for Solving the Problems) The present invention provides a thermoplastic resin containing 0.1 to 10% by weight of a light-diffusing inorganic compound with an average particle size of 1 to 10 μm and 0% of a pearl pigment.
．． This is a resin composition containing 1 to 5% by weight.

プロピレン等のポリオレフィン系樹脂およびポリスチレ
ン、ＡＢＳ等のスチレン系樹脂、ポリ塩化ビニル、ポリ
エチレンテレフタレート等である。Thermoplastic resins used in the present invention include polyolefin resins such as polyethylene and polypropylene, styrene resins such as polystyrene and ABS, polyvinyl chloride, and polyethylene terephthalate.
本発明の光拡散性無機化合物は、光散乱性とするため多
角結晶構造を有しているものが好ましい。The light-diffusing inorganic compound of the present invention preferably has a polygonal crystal structure in order to provide light-scattering properties.
このような無機化合物としては、炭酸カルシウム、炭酸
バリウム、炭酸マグネシウム、硫酸バリウム、シリカ等
がある。好ましい光拡散性無機化合物としては、ダイヤ
形単結晶構造を有する炭酸カルシウムであり、これは光
拡散剤として上布されている。Examples of such inorganic compounds include calcium carbonate, barium carbonate, magnesium carbonate, barium sulfate, and silica. A preferred light-diffusing inorganic compound is calcium carbonate having a diamond-shaped single crystal structure, which is coated as a light-diffusing agent.
光拡散性無機化合物は、平均粒子径が１〜１０ミクロン
であり、粒子径が１ミクロン以下の場合であると光拡散
現象が充分に発現せず、１０ミクロン以上では艶消効果
が顕著となるので光沢を微妙に調整することが困難とな
る。The light-diffusing inorganic compound has an average particle size of 1 to 10 microns, and if the particle size is less than 1 micron, the light-diffusing phenomenon will not be sufficiently expressed, and if it is more than 10 microns, the matting effect will be noticeable. Therefore, it is difficult to finely adjust the gloss.
光拡散性無機化合物の配合量は成形用熱可塑性樹脂に対
して、０．１〜１０重量％が好ましく、０゜１重量％以
下では光拡散効果が充分に発現せず、１０重量％以上で
は成形性や成形物の物性を低下させるため好ましくない
。The amount of light-diffusing inorganic compound compounded is preferably 0.1 to 10% by weight based on the thermoplastic resin for molding. If it is less than 0.1% by weight, the light-diffusing effect will not be sufficiently expressed, and if it is more than 10% by weight, This is not preferable because it reduces moldability and physical properties of the molded product.
また本発明に使用されるパール顔料は金属酸化物被覆雲
母系の合成パール顔料であればいずれのものでもよい。Further, the pearl pigment used in the present invention may be any metal oxide-coated mica-based synthetic pearl pigment.
成形用熱可塑性樹脂への配合量は０．１〜５重量％であ
り、０．１重量％以下では光沢が不充分となり、５重量
％以上では成形性や成形品物性を低下させるので好まし
くない。The blending amount in the thermoplastic resin for molding is 0.1 to 5% by weight, and if it is less than 0.1% by weight, the gloss will be insufficient, and if it is more than 5% by weight, it will deteriorate the moldability and physical properties of the molded product, so it is not preferable. .

以上の試験成形品に対し、蛍光灯下における成形品表面
のパール光沢および光沢のキメ細かさを目視で５段階に
評価した結果を表−１に示す。Table 1 shows the results of visually evaluating the pearlescent luster and fineness of the gloss on the surface of the molded product under a fluorescent lamp on a five-grade scale for the above test molded products.

光沢を与えることがわかる。また各々の実施例において
いずれも成形性は良く、得られた試料の物性低下は見ら
れなかった。From Table 1, it can be seen that the combined use of a light diffusing material and a pearl pigment gives the surface of the molded product a fine-grained and elegant luster even at a low blending amount. Furthermore, in each of the Examples, the moldability was good, and no deterioration in the physical properties of the obtained samples was observed.
以上のとおり、本発明の樹脂組成物は、成形品表面にキ
メ細かく優雅な光沢を与えるものである。As described above, the resin composition of the present invention provides a finely textured and elegant gloss to the surface of a molded article.
さらに光拡散性無機化合物およびパール顔料の成形用樹
脂材料への配合量が少量ですみ、成形性や成形品の物性
等を損うことなく、
優雅な光沢を付
与し得るものである。Furthermore, the amount of the light-diffusing inorganic compound and pearl pigment added to the resin material for molding is small, and an elegant luster can be imparted without impairing the moldability or physical properties of the molded product.
