The azo metal complex pigment for high density optical disk record media which is displayed with production mannered null formula (i) of the high density optical disk record media which

摘要

This invention provides azo-metal complex dyes for a high-density optical disc recording medium having the following formula (I):wherein R1 reprents C1-8 alkoxyl, carboxy, C1-8 alkoxycarbonyl, or amide; R2, R3, R4 and R5 can be the same or not, which are hydrogen, C1-8 alkyl, C1-8 alkoxyl, carboxy, C1-8 alkoxycarbonyl; C1-6 alkylaminealkylenecarboxy, amide, nitro, trifluoro-methyl, sulfonic acid fluoride group, sulfonic acid group or halogen atom; X reprents carbon or nitrogen atom; and M reprents Mg+2, Mn+2, Co+2, Ni+2, Cu+2 or Zn+2, These azo-metal complex dyes whose spectra are capable of matching wavelength of 400 nm~700 nm visible light can be used as a high-density optical disc recording medium.
