子効率の改善が達成される。HEMA of the carrier in the present invention is a functional group having a large polarity,
Since it has a C═O group and an OH group, the absorption spectrum of the optical recording material becomes longer in wavelength. Further, it is considered that the change in the interaction with the functional group of HEMA based on the hydrogen bond causes the PHB reaction, and the functional group of the optical recording medium, for example, OH,
The larger the number of NH 2 and C═O, the easier the interaction. That is P
Easy to cause HB reaction. On the other hand, if the molecular structure is large, it is considered that the chance of interaction is reduced. It is considered that when the number of functional groups is large and the molecular structure is small, the PHB reaction is likely to occur, the density of optical recording is increased and the quantum efficiency is improved. ABDAQ has 2 OH groups and 1 NH 2 group.
Since ABTAQ has 3 OH groups and 1 NH 2 group and has a large number of functional groups and a small molecular structure as compared with the conventional example, higher density and improved quantum efficiency can be achieved.

It was observed that it was demonstrated that the film to which the optical recording material of this example was applied was capable of multiple recording by PHB reaction. The optical recording density is 20 multiples / nm, which is double that of the conventional example, and the quantum efficiency is improved to 5 × 10 -4 .
