Title:
RESIN COMPOSITION AND UNSTRETCHED OPTICAL FILM
Document Type and Number:
WIPO Patent Application WO/2021/182217
Kind Code:
A1
Abstract:
This resin composition contains: (B) 0.0001-0.2 parts by weight of a composite tungsten oxide particle (component B) represented by general formula MxWyOz (where M is at least one element selected from among H, He, an alkali metal, an alkaline earth metal, a rare earth element, Mg, Zr, Cr, Mn, Fe, Ru, Co, Rh, Ir, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Al, Ga, In, Tl, Si, Ge, Sn, Pb, Sb, B, F, P, S, Se, Br, Te, Ti, Nb, V, Mo, Ta, Re, Be, Hf, Os, Bi, and I; W is tungsten; O is oxygen; 0.001≤x/y≤1; and 2.2≤z/y≤3.0); (C) 0.0001-0.1 parts by weight of an epoxy resin (component C); and (D) 0.001-0.5 parts by weight of a mold releasing agent (component D) which is a fatty acid ester containing, as a main component, a full ester consisting of a fatty acid and a polyhydric alcohol, with respect to 100 parts by weight of (A) a polycarbonate resin blend or copolymer (component A) having main repeating units including a carbonate unit (a-1) having a fluorene ring in the side chain, a carbonate unit (a-2) represented by formula (a-2) (in the formula, W represents a C1-20 alkylene group or C6-20 cycloalkylene group, R represents a C1-20 branched or straight chain alkyl group, or a C6-20 cycloalkyl group which may have a substituent, and u represents an integer of 0-3), and a carbonate unit (a-3) derived from 2,2-bis(4-hydroxyphenyl)propane, wherein the molar ratio of the carbonate unit (a-1) to the carbonate unit (a-2) is 50/50 to 80/20, and the molar ratio of the sum of the carbonate unit (a-1) and the carbonate unit (a-2) to the carbonate unit (a-3) is 1:99 to 70:30. The resin composition is characterized by having high heat resistance, bending resistance, and moisture-heat resistance, excellent transparency, and a low three-dimensional phase difference.
