The present disclosure relates to a light transmissive molded article and interior meterials of an automobile. The article includes a base layer and a coating 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 DEG C. for 500 hours, a color difference deltaE1 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. Equation 1:deltaE1<=2.0, Equation 2: 0.95<=TA/T0<=1.05.
本公开涉及透光模制品和汽车内饰部件。该透光模制品包括基础层和涂层，其中当按照ASTM D3763使用直径为12.7mm且厚度为3.0mm的棒施加140J的冲击能量时，峰值能量PEA等于或大于40J，其中当在90℃下暴露500小时时，基于暴露前CIE LAB色彩空间的色坐标(L*0,a*0,b*0)和暴露后CIE LAB色彩空间的色坐标(L*A,a*A,b*A)的色差ΔE1满足以下方程式1，并且暴露前的透光率T0和暴露后的透光率TA满足以下方程式2：[方程式1]ΔE1≤2.0[方程式2]0.95≤TA/T0≤1.05。
