OPTICAL IMAGE RECORDING/READING MEDIUM
Document Type and Number:
Japanese Patent JPS5926293
Kind Code:
A
Abstract:
PURPOSE: To obtain a recording medium capable of efficiently absorbing semiconductor laser light of a wavelength of 650W800nm to record an image, by producing an image recording/reading medium by incorporating a specified anthraquinone compound.
CONSTITUTION: A solution of an anthraquinone compound of the formula (wherein R1 is 1W16C straight chain or branced alkyl, cycloalkyl, alkenyl, aralkyl or aryloxyalkyl which may be interrupted by 1W5 oxygen atoms or an aryl which may have 1W12C alkyl or alkoxy as a sustituent group; R2 is hydrogen or 1W 4C alkyl) in a solvent is prepared.
