Description
本発明のポリカーボネート樹脂組成物は、射出成形した多目的試験片を用い３００ｍｍの光路長で測定した際のイェローインデックス（ＹＩ）が、好ましくは２５以下である。本発明のポリカーボネート樹脂組成物は、このように長い光路長にて測定されるＹＩが２５以下であり、優れた色調を保持することができる。
また、本発明のポリカーボネート樹脂組成物は、ＪＩＳ Ｋ７１５３に準拠して射出成形した多目的試験片を用い３００ｍｍの光路長で測定した際の光線透過率が高く、導光板の輝度が向上する。
ここで、ＹＩ及び光線透過率を測定する多目的試験片の成形は、後記実施例に記載の方法に従って行われる。
The polycarbonate resin composition of the present invention, Yellow index measured at a light path length of 300mm using the I De molded multipurpose test specimen (YI) is preferably 25 or less. The polycarbonate resin composition of the present invention has a YI measured with such a long optical path length of 25 or less, and can maintain an excellent color tone.
Further, the polycarbonate resin composition of the present invention has a high light transmittance when measured with an optical path length of 300 mm using a multipurpose test piece injection-molded according to JIS K7153, and the brightness of the light guide plate is improved.
Here, the molding of the multi-purpose test piece for measuring YI and light transmittance is performed according to the method described in Examples below.
