Description
（１）本発明の複合樹脂組成物は、平均直径が３〜４００ｎｍであるセルロースナノファイバーを樹脂中に含有する複合樹脂組成物であって、前記樹脂の屈折率と前記セルロースナノファイバーの屈折率の差の絶対値が０．０２以下であることを特徴とする。
（２）本発明の複合樹脂組成物は、さらに１種以上の着色剤を含有することが好ましい。
（３）本発明の複合樹脂組成物は、前記１種以上の着色剤のうち、少なくとも１種は光沢粒子であることが好ましい。
（４）本発明の複合樹脂組成物は、前記セルロースナノファイバーの水酸基が修飾基により化学修飾されていることが好ましい。
（５）本発明の複合樹脂組成物は、前記セルロースナノファイバーは、Ｉβ型のセルロースにより製造されることが好ましい。
（６）本発明の複合樹脂組成物は、前記樹脂がポリカーボネート樹脂、又はアクリル樹脂であるであることが好ましい。
（７）本発明の複合樹脂組成物は、前記樹脂がポリカーボネート樹脂であり、さらに光沢粒子を含有することが好ましい。
（８）本発明の成形体は、先に記載の複合樹脂組成物を成形してなることを特徴とする。
(1) The composite resin composition of the present invention is a composite resin composition containing cellulose nanofibers having an average diameter of 3 to 400 nm in a resin, the refractive index of the resin and the refractive index of the cellulose nanofibers. The absolute value of the difference is 0.02 or less.
(2) It is preferable that the composite resin composition of the present invention further contains one or more colorants.
(3) In the composite resin composition of the present invention, it is preferable that at least one of the one or more colorants is a glossy particle.
(4) In the composite resin composition of the present invention, the hydroxyl group of the cellulose nanofiber is preferably chemically modified with a modifying group.
(5) In the composite resin composition of the present invention, the cellulose nanofiber is preferably produced from Iβ-type cellulose .
(6) In the composite resin composition of the present invention, the resin is preferably a polycarbonate resin or an acrylic resin.
(7) In the composite resin composition of the present invention, it is preferable that the resin is a polycarbonate resin and further contains glossy particles.
(8) The molded body of the present invention is characterized by being formed by molding the composite resin composition described above.
前記（Ｂ）セルロースナノファイバーの製造には、Ｉα型、Ｉβ型のセルロースの両方が好適に使用できる。本発明に用いられる（Ｂ）セルロースナノファイバーはどちらを用いても良いが、Ｉβ型を主成分とした方が、（Ａ）樹脂に対する補強効果が高い点から好ましい。このため、Ｉα型が確認されない図１に示されるようなθの範囲を０〜３０とするＸ線回折パターンが、１４≦θ≦１８に１つ又は２つのピークと、２０≦θ≦２４に１つのピークとを有し、他にはピークを有さないものが特に好ましい。 For the production of the (B) cellulose nanofiber, both Iα type and Iβ type cellulose can be suitably used . Either of the (B) cellulose nanofibers used in the present invention may be used, but it is preferable to use the Iβ type as a main component because (A) the reinforcing effect on the resin is high. For this reason, an X-ray diffraction pattern in which the range of θ is 0 to 30 as shown in FIG. 1 in which the type Iα is not confirmed is one or two peaks at 14 ≦ θ ≦ 18, and 20 ≦ θ ≦ 24. Particularly preferred is one having one peak and the other having no peak.
