That is, the present invention is as follows.
(1) A resin composition comprising (A) a polylactic acid resin, (B) a methacrylic resin, and (C) a thermoplastic resin having a refractive index in the range of 1.45 to 1.50 ,
The weight ratio of (A) polylactic acid resin to (B) methacrylic resin is 70/30 to 10/90, and
The weight ratio of (A) the polylactic acid resin and (B) the methacrylic resin and (C) the thermoplastic resin having a refractive index in the range of 1.45 to 1.50 is 99/1 to 1/99. A resin composition,
(2) The resin composition according to (1), wherein the thermoplastic resin (C) having a refractive index in the range of 1.45 to 1.50 is a cellulose resin,
(3) The resin according to (2), wherein (C) the cellulose-based resin has a hydroxyl group substitution degree (average number of hydroxyl groups substituted with cellulose ester) of 0.5 to 2.9 per glucose unit. Composition,
(4) The resin composition according to any one of (1) to (3) , which has a haze of 10% or less when molded into a thickness of 1 mm,
(5) A molded article comprising the resin composition according to any one of (1) to (4) .
本発明において、（Ａ）ポリ乳酸樹脂および（Ｂ）メタクリル系樹脂の組成は、透明性の点で、重量比として、７０／３０〜１０／９０であり、６５／３５〜１５／８５が特に好ましく、６３／３７〜３０／７０が最も好ましい。 In the present invention, the composition of (A) polylactic acid resin and (B) methacrylic resins, in terms of transparency, as a weight ratio, a 7 0/3 0 10/90, 65 / 35-15 / 85 Is particularly preferable, and 63/37 to 30/70 is most preferable.
本発明において、（Ａ）ポリ乳酸樹脂、（Ｂ）メタクリル系樹脂および（Ｃ）屈折率が１．４５〜１．５０の範囲である熱可塑性樹脂の配合比は、（Ａ）ポリ乳酸樹脂および（Ｂ）メタクリル系樹脂の合計量と（Ｃ）屈折率が１．４５〜１．５０の範囲である熱可塑性樹脂の重量比として、９９／１〜１／９９であり、耐熱性および透明性の点で、９０／１０〜５／９５であることがより好ましく、７０／３０〜１０／９０であることがさらに好ましく、６５／３５〜３０／７０であることが特に好ましい。このような配合比とすることで、耐熱性と透明性をバランスよく備えた樹脂組成物を得ることができる。 In the present invention, the blending ratio of (A) polylactic acid resin, (B) methacrylic resin and (C) thermoplastic resin having a refractive index in the range of 1.45 to 1.50 is ( A) polylactic acid resin and (B) as the weight ratio of the thermoplastic resin the total amount of the methacrylic resin and (C) a refractive index in the range of 1.45 to 1.50, 99 / 1-1 / 99 der is, heat resistance and transparency From the viewpoint of properties, 90/10 to 5/95 is more preferable, 70/30 to 10/90 is further preferable, and 65/35 to 30/70 is particularly preferable. By setting it as such a compounding ratio, the resin composition provided with heat resistance and transparency with sufficient balance can be obtained.
