SPECIAL POLYCARBONATE POLARIZING EYEWEAR |
摘要 |
The present invention makes it possible to provide eyewear which uses a polarizing lens obtained by bending a multilayer polarizing sheet in which a sheet (A) including at least 50% by mass of an aromatic polycarbonate resin and having a retardation value of 2000 nm or less at a wavelength of 600 nm is layered on one side of a polarizing film, and a sheet (B) including a special polycarbonate resin obtained by carbonate bonding a dihydroxy compound through use of a carbonic acid diester, the polycarbonate resin being a compound in which 70-100 mol% of the dihydroxy compound is represented by general formula (1), is layered on the other side of the polarizing film.
(In general formula (1), R 1 and R 2 are each independently a hydrogen atom, a C 1 -C 20 alkyl group, or the like. In general formula (1), X are each independently a C 2 -C 8 alkylene group or the like.) |
