The dye disclosed in No. 3 has the advantage of being easy to vapor deposit, but has the problem of low reflectance. If the reflectance is low, the contrast related to the reflectance between the portion recorded by the laser beam and the unrecorded portion will be low, making it difficult to reproduce the recorded information. Additionally, organic dyes generally have a problem of poor storage stability.
