Abstract
The present invention provides a fluorinated alcohol for manufacturing an optical recording medium that is superior in the characteristics and weatherability, and an optical recording medium having an organic dye layer formed by using the fluorinated alcohol.A fluorinated alcohol for manufacturing an optical recording medium having an organic dye layer and a reflecting layer in this order on a light-transmittable substrate, wherein a content of a high-boiling-point fluorinated alcohol with a boiling point of not less than 120° C. is 0.001% by weight or less. An optical recording medium is provided with an organic dye layer formed by using the ultra-high purity fluorinated alcohol.
