昇華した染料の金型への付着によって凹部が埋められ、
情報記録のエラーが増大する。In particular, if the melting point exceeds 250° C., the dye will not be sufficiently melted during processing of the polycarbonate resin, and will cohere in the parts, impeding the transmission of the focused small diameter light beam. In addition, it is desirable that the sublimation start temperature is high, and in order to prevent sublimation during processing of polycarbonate resin, a temperature of 230℃ is recommended.
It is necessary to have a salinity at the start of sublimation. In particular, when injection molding an information recording base such as a base for a compact disc or an optical disc, 320 mm is used to reduce optical distortion.
Since it is processed at a high temperature of ~360°C, it is required that the dye has high heat resistance. Moreover, the fine unevenness for recording information formed on the surface layer of the substrate is caused by a large amount of dye sublimation.
The recesses are filled by the adhesion of sublimated dye to the mold,
Increased errors in information recording.
