SUBSTRATE MATERIALS FOR TRANSPARENT INJECTION MOULDINGS

摘要

A polycarbonate resin comprising fluorescing particles that feature a particular size distribution is disclosed. The size distribution of these particles that fluoresce upon excitation at wavelengths of 400-440 nm, 50x magnification and illumination time of 40 msec per scan was found to be critical in determining the suitability of the resin for optical, particularly optical storage, applications.
