RESIN COMPOSITION CAPABLE OF PHASE SEPARATION, WRITABLE RESIN COMPOSITION FOR OPTICAL RECORDING AND OPTICAL RECORDING MEDIUM USING THE SAME, METHOD OF RECORDING INFORMATION USING THE OPTICAL RECORDING MEDIUM

摘要

PROBLEM TO BE SOLVED: To provide a resin composition to be used for an optical recording medium which is a rewritable optical recording medium using an anthracene derivative as an optical recording material, easy to make thin film and capable of using base materials having a convexoconcave or a curved surface.SOLUTION: A writable resin composition for optical recording contains the general formula (1), where n is an integer of 1 to 20, in a polymer matrix consisting of a polymer having a glass transformation temperature of 150°C, and the polymer and the anthracene derivative form a phase separation structure.
