である。Due to such photochromic properties, research has been conducted to use spiropyran compounds as functional dyes in additional recording type recording materials, and up to now, 8,500 compounds with 50 kinds of chemical structures have been synthesized. . However, when a merocyanine-type compound is used, the photochromic property rather acts as a disadvantage because the chemical structure of the merocyanine-type compound changes due to heat or visible light. One way to eliminate this heat and visible light instability is to protect the hydroxyl groups of the merocyanine form of the compound with other functional groups.

る。On the other hand, a patent has been filed (US Pat. No. 6,103,331) in which a styryl cyanine dye represented by the following general formula is used as a substance for an optical recording layer. The optical recording dye having such a structure does not utilize the photochromic property and causes photolysis by absorption of the used laser wavelength. This causes a change in the refractive index and the reflectance between the portion irradiated with the laser and the portion not irradiated with the laser. That is, the requirement for such a photo-degradable recording dye is that the laser used (for example, 635 nm or
650 nm wavelength), large molar extinction coefficient, excellent heat and light stability, large change in refractive index during thermal decomposition, excellent solubility, thin film formed by spin casting Are often made.
