【発明の属する技術分野】
本発明は、顔料の分散剤や樹脂の改質添加等として硬化ヒマシ油を使用する際の熱可塑性樹脂の混練性が改善され、顔料の分散性に優れ、造粒化（ペレット化）が可能な加工性が改善された樹脂組成物に関する。
【０００２】
【従来の技術】
硬化ヒマシ油は、耐熱性が良好で、透明性に優れることから、各種熱可塑性樹脂の改質添加剤あるいは顔料分散剤として従来から使用されており、特に、加工温度が高い該樹脂には耐熱性が良好であることから好んで使用されている。
しかしながら、ペレット状の着色樹脂組成物を２軸押出機等によって製造する際、硬化ヒマシ油は融点が低いために該樹脂をスクリューとシリンダー間でスリップさせて押出加工性を阻害し、顔料の分散性やペレット化に支障を来すことがあった。
【０００３】
【発明が解決しようとする課題】
本発明はこのような事情に鑑みてなされたものであり、本発明の目的は、硬化ヒマシ油を顔料の分散剤や樹脂の改質添加剤等として使用する際の、熱可塑性樹脂の混練性が改善され、顔料の分散性に優れ、造粒化（ペレット化）が可能な加工性が改善された樹脂組成物を提供することである。
本発明者らは、上記目的を達成すべく鋭意検討した結果、熱可塑性樹脂に着色剤と硬化ヒマシ油を配合して押出加工する際に、更に熱可塑性エラストマー又は特定なポリエステルを配合することにより、硬化ヒマシ油の添加量が多い場合にも、混練性が良好で、顔料の分散性も良好なペレット化が可能な着色樹脂組成物が得られることを見出し、本発明を完成するに至った。
【０００４】
【課題を解決するための手段】
上記の目的は以下の本発明によって達せられる。即ち、本発明は、ＡＢＳ樹脂に硬化ヒマシ油、着色剤及びアクリル系エラストマーが添加され、上記硬化ヒマシ油の配合量が上記ＡＢＳ樹脂１００重量部に対して０．１〜３０重量部であり、上記着色剤の配合量が上記ＡＢＳ樹脂１００重量部に対して０．１〜５０重量部であり、上記アクリル系エラストマーの配合量が上記ＡＢＳ樹脂１００重量部に対して１〜３０重量部であることを特徴とする加工性が改善された樹脂組成物、および

【発明の実施の形態】
次に発明の実施の形態を挙げて本発明を詳細に説明する。
先ず、本発明で使用する各成分について説明する。
熱可塑性樹脂としては、ＡＢＳ樹脂およびポリエチレンテレフタレート樹脂が挙げられる。
【０００６】
本発明で使用する硬化ヒマシ油は、ヒマシ油を水素添加反応によって完全硬化して得られる１２−ヒドロキシステアリン酸のトリグリセリドであり、Ｋ−３ワックスやカワスターＣＲ（いずれも川研ファインケミカル社製）等の市販品が入手可能である。硬化ヒマシ油の使用量は熱可塑性樹脂１００重量部に対して０．１〜３０重量部の割合である。
【０００７】
本発明で使用する着色剤として、従来公知の無機及び有機顔料がいずれも使用でき、特に限定されない。無機顔料としては、例えば、群青、紺青、コバルトブルー等の各種複合酸化物顔料、酸化チタン、カーボンブラック等が、有機顔料としては、例えば、アゾ顔料（溶性、不溶性及び縮合）、フタロシアニン顔料（銅及び無金属）、縮合多環顔料（例えば、アントラキノン系、ペリレン系、ペリノン系、キナクリドン系、ジオキサジン系、イソインドリノン系、キノフタロン系等）等が挙げられる。これらの着色剤の使用量は熱可塑性樹脂１００重量部に対して０．１〜５０重量部の割合である。

Hardened castor oil has been conventionally used as a modification additive or pigment dispersant for various thermoplastic resins because it has good heat resistance and excellent transparency, and is particularly resistant to the resin having a high processing temperature. It is preferably used because of its good properties.
However, when producing a pellet-shaped colored resin composition with a twin-screw extruder or the like, the hardened castor oil has a low melting point, so that the resin slips between the screw and the cylinder, impairing the extrusion processability, and dispersing the pigment. This may hinder the performance and pelletization.

As a result of diligent studies to achieve the above object, the present inventors have further blended a thermoplastic elastomer or a specific polyester with a thermoplastic resin when a colorant and hardened castor oil are blended and extruded. In addition, even when the amount of hardened castor oil added is large, it was found that a colored resin composition capable of being pelletized with good kneadability and good dispersibility of the pigment was obtained, and the present invention was completed. .

[0006]
The hydrogenated castor oil used in the present invention is a triglyceride of 12-hydroxystearic acid obtained by completely curing castor oil by hydrogenation reaction, such as K-3 wax and Kawastar CR (both manufactured by Kawaken Fine Chemical Co., Ltd.). Are commercially available. The amount of hydrogenated castor oil Ru Ah in a proportion of 0.1 to 30 parts by weight per 100 parts by weight of the thermoplastic resin.
[0007]
As the colorant used in the present invention, any conventionally known inorganic and organic pigments can be used and are not particularly limited. Examples of inorganic pigments include various complex oxide pigments such as ultramarine, bitumen, and cobalt blue, titanium oxide, and carbon black. Examples of organic pigments include azo pigments (soluble, insoluble, and condensed), and phthalocyanine pigments (copper). And non-metal), condensed polycyclic pigments (for example, anthraquinone, perylene, perinone, quinacridone, dioxazine, isoindolinone, quinophthalone, etc.). The amount of these colorants Ru Ah in a proportion of 0.1 to 50 parts by weight per 100 parts by weight of the thermoplastic resin.
[0008]
The thermoplastic elastomer used in the present invention, A chestnut Le elastomer (e.g., ethylene - acrylic acid copolymer (EEA), ionomer, a so-called acrylic rubber (e.g., ethyl acrylate - acrylonitrile copolymer rubber, butyl acrylate homopolymer etc.)), and the like. The amount of the d elastomer is a proportion of 1 to 30 parts by weight per 100 parts by weight of the thermoplastic resin. If the amount is less than 1 part by weight, the workability is insufficiently improved, and even if the amount exceeds 30 parts by weight, the effect of improving the workability corresponding to the amount used cannot be obtained, which is uneconomical. More preferably, it is a ratio of 2 to 10 parts by weight.
[0009]
A melting point to be used is 200 ° C. or less in the present invention, the following polyester glass transition temperature of 30 ° C., a melting point (ring and ball method (JIS K2531) is 1 23 ° C., a glass transition temperature (Tg: measured by DSC) is - 7 is a 0 ℃ polyester copolymer (trade name GM913). the amount of the polyester copolymer is the same as the case of the thermoplastic elastomer.
[0010]
The resin composition of the present invention can be produced by kneading a thermoplastic resin and each of the above components with a twin screw extruder or the like and extruding them into pellets. At that time, the idle rotation of the screw due to the molten hardened castor oil is suppressed, and each component can be fed from the feed part to the kneading part and sufficiently kneaded in the kneading part, and the colored resin composition having good colorant dispersion. Pellets can be produced. In the kneading, an effective amount of an additive such as an antioxidant can be appropriately added as necessary.

Each component was weighed according to the formulation shown in Table 1 below, and kneaded and granulated (pellet) processed with a 45 mm twin screw extruder (average cylinder temperature 280 ° C.). When the polyester copolymer was not used, the screw was idled by the action of the molten hardened castor oil, and each component was not sent from the feed part to the kneading part, and kneading and pelletization were not possible. On the other hand, when the polyester copolymer was added, idle rotation of the screw did not occur, and each component was sufficiently kneaded, extruded from the die, and cut by a cutter to be pelletized. Also, the dispersibility of the pigment was good.
