Title:
RESIN MOLDED ARTICLE
Document Type and Number:
WIPO Patent Application WO/2016/017528
Kind Code:
A1
Abstract:
The present invention pertains to a resin molded article obtained by molding a resin composition containing a cyclic olefin resin and a styrene thermoplastic elastomer, wherein: the styrene thermoplastic elastomer has a weight-average molecular weight of 20,000-150,000, and the difference (ΔnD) between the refractive index thereof and the refractive index of the cyclic olefin resin is greater than -0.002 and less than +0.002; the residue is 0.10 wt% or less when analyzing the resin composition on the basis of the residue-on-ignition test stipulated by the Japanese Pharmacopoeia; the light transmittance (optical path length of 3mm) of light having a wavelength of 450nm is 55% or higher, when molding the resin composition into a sheet having a thickness of 3.0mm and measuring the light transmittance using said sheet; and the Charpy impact strength is 5-40kJ/m2, when molding the resin composition into a shape having a thickness of 4.0mm, a length of 80.0mm, and a width of 10.0mm, and subjecting the same to the notch Charpy impact test stipulated by JIS K7111-1 at 23°C.
