RESIN COMPOSITION FOR OPTICAL RECORDING MEDIUM

摘要

PURPOSE:To prevent a dye from being discolored, by a method wherein a poly- alpha-methylstyrene resin composition having a specified bromine number is used in combination with a transition metal containing dye as a material for a laser optical recording/reading medium. CONSTITUTION:A poly-alpha-methylstyrene having a bromine number of not more than 100 is used as an organic high molecular weight compound to be combined with a transition metal containing dye to which semiconductor laser can be applied. Accordingly, an optical recording/reading medium free of spontaneous discoloration can be produced.
