Abstract

PURPOSE:To enhance reflectivity and obtain an output satisfactory as a reproduction signal, by incorporating a specified indolenine cyanine. CONSTITUTION:A heat-mode direct-read-after-write type optical data recording medium comprises an indolenine cyanine of general formula [I], wherein each of R1 and R1' is a substd. or unsubstd. alkyl or alkoxyl, each of R2 and R2' represents one or more substituent groups at least one of which is nitro, X1<-> is an anion such as halide ion, perchlorate ion and fluoroborate ion, and B is pentamethine. To produce the optical information recording medium, a coloring matter solution containing the indolenine cyanine of general formula [I] is prepared, and is applied to a substrate. The solution may be prepared by using a solvent such as an alcohol solvent (e.g., methanol, ethanol) and chloroform. The proportion of the cyanine coloring matter is preferably 1-10%.
