본 발명은 광투과성 성형품에 관한 것으로, 열가소성 수지 조성물로부터 성형된 기재층 및 기재층의 적어도 일측 표면에 형성된 도장층을 포함하고, ASTM D3763에 의해 3.0 mm 두께에서 직경 12.7 mm의 로드로 140 J의 충격 에너지를 가하였을 때 피크 에너지(PEA)가 40 J 이상이며, 90 ℃에서 500 시간 노출하였을 때, 노출 전의 CIE LAB 색공간의 색좌표(L*0, a*0, b*0)와 노출 후의 CIE LAB 색공간의 색좌표(L*A, a*A, b*A)에 따른 색차(△E1)가 하기 수학식 1을 만족하고, 노출 전의 광투과율(T0)과 노출 후의 광투과율(TA)이 하기 수학식 2를 만족하는 것인 광투과성 성형품에 관한 것이다. [수학식 1] △E1 ≤ 2.0 [수학식 2] 0.95 ≤ TA/T0 ≤ 1.05

    The present disclosure relates to a light transmissive molded article including a base layer molded from a thermoplastic resin composition and a coating layer formed on at least one surface of the base layer, wherein peak energy PEA is equal to or greater than 40 J when impact energy of 140 J is applied with a rod having a diameter of 12.7 mm and a thickness of 3.0 mm by ASTM D3763, wherein, when being exposed at 90° C. for 500 hours, a color difference ΔE1 based on color coordinates (L*0, a*0, b*0) of a CIE LAB color space before the exposure and color coordinates (L*A, a*A, b*A) of the CIE LAB color space after the exposure satisfies Equation 1 below, and light transmittance T0 before the exposure and light transmittance TA after the exposure satisfy Equation 2 below:ΔE1≤2.0  [Equation 1]0.95≤TA/T0≤1.05.  [Equation 2]
