RADIATION-CURABLE COATINGS FOR OPTICAL DISCS AND OPTICAL DISCS INCORPORATING SUCH COATINGS

摘要

Optical disc, e.g., CD-R, DVD, DVD-R, comprising a polymer substrate and a radiation-cured coating provided by curing a radiation-curable coating composition having a pH greater than or equal to 3 and comprising at least one acrylate monomer, and advantageously diacrylate monomers and oligomers and monomers having acrylate functionalities of from 1 to at least 3, wherein the optical disc exhibits jitter of no greater than about 35 ns after being subjected to an environment having a temperature of at least 80 DEG C and a relative humidity of at least 85 % for a period of at least 96 hours.
