Abstract (en)
[origin: WO0015425A1] A dye-in-polymer composition for use in fluorescent WORM discs comprises about 0.1 to 10% by weight of a fluorescent dye capable of absorbing laser radiation and transforming the absorbed light into heat; about 10 to 80% by weight of nitrocellulose and a film forming polymer. The dye containing solution is applied to a substrate of an optical reading medium by a spin, roller or dip coating. The method utilizes a focused laser beam for scanning the recording layer.
